[Bug 1884850] Re: Xorg server uses unacceptably large amounts of memory (and keep growing) when LibreOffice is running
One point of observation. Since this time, I am switching to Debian 10 for daily work because I couldn't bear X11 memory growth. The package information for my Debian install: * xserver-xorg version 1:7.7+19 * xserver-xorg-video-intel version 2:2.99.917+git20180925-2 * linux-image-4.19.0-17-amd64 version 4.19.194-3 (stock kernel, unmodified) This does not produce the same kind of unabated memory growth. Please let me know if anything can be done to help diagnose the problem. I have not gotten rid of the Ubuntu 20.04 install yet, though I had switched to xfce for daily work, before eventually I installed Debian 10. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1884850 Title: Xorg server uses unacceptably large amounts of memory (and keep growing) when LibreOffice is running To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1884850/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Dave, I am suspecting a bug with the X hardware driver. Can you please describe the machine you are using. Plus produce the output of "lspci" and "lsmod"?

[Bug 1884850] Re: Xorg server uses unacceptably large amounts of memory (and keep growing) when LibreOffice is running
Here is a fuller analysis (see next attachment, Xfce- session-20200922-analysis.html). I started LibreOffice on 9/22 nearly exclusively on a new Xfce session. (Except for the MATE terminal app, again). I edited a few documents, as indicated in the analysis. Every time without exception, the X pixmap memory usage grew. My previous attachment (graph) showed that the X memory usage eventually exploded after an extended period of time the LO Writer app was open--nearly a month. This time, I did not do that. But I managed to show in the graph that almost every document edit leads to a significant increase in the X pixmap memory usage (5 MB, 10 MB, and even 20 MB just looking at the graph). The problem is, once the LibreOffice is closed, the X pixmap memory usage won't shrink anymore. I do have the xrestop snapshots of the LibreOffice usage but haven't had chance to process the data to graph it. Ask me if that is desired. But I will send the script that polls the memory usage as a second attachment in case that is useful for others to monitor the memory growth. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1884850 Title: Xorg server uses unacceptably large amounts of memory (and keep growing) when LibreOffice is running To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1884850/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1884850] Re: Xorg server uses unacceptably large amounts of memory (and keep growing)
Update 20200922 I have tested LibreOffice for a while. It did cause Xorg memory explosion again as explained below. I am excerpting my own personal notes here, please bear with the rough form of it. The graph that I will attach next will show the point. I started using a LibreOFfice program at 2020-09-06; this was a relaunch after the last comment. At timestamp = 20200921T2330, I checked Xorg memory usage tonight after leaving LibreOffice open for over 11 days: Xorg RSS became swollen to over 1 GB! xorg RSS ... 1182768 kiB The "free" status was terrible: totalusedfree shared buff/cache available Mem: 12144888 9761024 596696 710552 1787168 1353420 Swap: 1808384 1477752 330632 Three major users of Xorg memory: LibreOffice Writer ( PID:1760594 ): pixmap bytes : 334753205 1 - xfwm4 ( PID:1477670 ): pixmap bytes : 141633828 Mozilla Firefox ( PID:1816946 ): pixmap bytes : 44090522 The total of all three is ~520 MB. LibreOffice alone is eating up over 334 MB of RAM! NOTE: I did not use LibreOffice every day on this machine. But I left that program open since it was opened on Sept 6. I used the LO Writer occasionally to make notes now and then. Now I am closing the LibreOffice program, see what happened. Before LibreOffice doc was closed, the mem usage status was: LibreOffice pixmap bytes usage dropped to 286360981 (pixmap bytes) xfwm4 131834529 (pixmap bytes) firefox 44090522 (pixmap bytes) xorg RSS 1203568 kiB => misleading, too much dumped to swap! Let's close LibreOffice; after closing (time marker = 20200922T0006) the usage: xfwm4 98517409 firefox 44090522 xorg RSS 1192256 kiB A few observations: * As you can see above, xorg RSS was NOT significantly reduced even after I closed the LibreOffice. That was not the case with Firefox or with Xpra; the memory usage dropped as soon as I closed those programs. * I also remember from my past observations that *when this Xorg memory explosion occurred*, the RSS of the xorg server is way higher than the (rough) sum total of the pixmap memory consumption reported by xrestop. My fuzzy memory has it at about a factor of 4: RSS(Xorg) ~ 4x sum(pixmap bytes reported by xrestop) The example above did not quite support that though, but still, it is a factor of more than two! * I also looked at smaps: (ref: smaps-1600747980-20200922T001300.txt). That file indicates the largest memory occupied is in the heap: $ grep -e '^[0-9a-f]' -e 'Dirty' smaps-1600747980-20200922T001300.txt ... 55aa90005000-55aad31ae000 rw-p 00:00 0 [heap] Shared_Dirty: 0 kB Private_Dirty: 1078916 kB ... Now I closed Firefox as well: (after closure, timestamp: 20200922T0034) xfwm4 61755763 xorg RSS 1149028 kiB Again, it looks like firefox X pixmap memory was freed ok (xorg RSS dropped by ~50 MB), but not much lower. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1884850 Title: Xorg server uses unacceptably large amounts of memory (and keep growing) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1884850/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1884850] Re: Xorg server uses unacceptably large amounts of memory (and keep growing)
I have tested two applications so far... 1) firefox + MATE terminal 2) xpra + MATE terminal I'm sorry I can't not use MATE terminal because I still have to use part of the laptop for work. In either case I did not notice too significant a memory growth. Again, the memory usage numbers mentioned below are the "RSS" reported by "ps". In the case of Firefox: memory usage is approximately ~130MB (I belive this was right after Firefox was started and fully running) to over ~150 MB after 7-8 days of use. But I tried this: I closed Firefox, the memory usage dropped to below 90 MB. So at least I know that Firefox X memory seems to be released. In the case of running xpra: before xpra is running (right after X server restart), X server memory usage is about 80 MB, and it goes up to ~120-130 MB after 3 days. It dropped back to 96MB. I don't fully know why this yet. Maybe there is some leak, but I also want to note that xfwm4 is uses significant amount of X memory. In this case and previous case, I also note that the xrestop reports increasing memory usage of "xfwm4" over time. Initially when the Xserver just restarted, xfwm4 uses ~30 MB of X memory. It goes up and down, seemingly dependent on how many windows are opened. So, no conclusion yet on that end. Note: I am running gnucash (or gnucash and firefox) on the XPRA server. I tend to think that the stuff I run under XPRA will to a good degree not affect the xserver being diagnosed except by the number of windows it displays. I have currently been running libreoffice on the existing session (xpra+MateTerm) just to find out how things are. I have personally suspected libreoffice and/or vlc. So far, libreoffice seems to exhibit this apparent behavior: when I am actively using it, the X server RSS goes up. But when I leave that libreoffice window alone, the RSS does not increase. I'll have to re-test this by itself and report back. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1884850 Title: Xorg server uses unacceptably large amounts of memory (and keep growing) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1884850/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Brief comment. Have restarted X server 3 days ago to run pretty much just Firefox + MATE terminal. Will let you know later how this goes. So far the X server memory usage (RSS) is about 125-130MB. Which is high, but not super terrible. Usually it takes a few more days before the usage swells. Another comment, xfwm4 is using quite a bit of X pixmap memory (50-54 MB as reported by xrestop). I have 4 desktops, and the laptop display ix FHD 1920x1080. I wonder if window image caching is what causing this. When it started it measured already at 30MB. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1884850 Title: Xorg server uses unacceptably large amounts of memory (and keep growing) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1884850/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi folks, an update on my VLC measurement. I finally did that "vlc -vvv", please see attachments for the stderr. I don't see anything interesting there. But I did make snapshots of the vsize, rss, and the "smaps" file under the /procfs/$PID/smaps --they are also attached. I played the same video for less than 12 minutes then paused it. Then let the window sit there like what I did before. The observation covered for about 20 hours total. The file "vlc-vvv-usage-wirawan2-Sisters_M16.txt" contains the output of "ps faux" commands taken over regular interval (timestamp shown as cols 1-2) for this one process. I plotted the vsize and rss from that ps output file (using pandas, in case you're curious), I did see linear growth in the memory usage in several stretches of time. And these stretches did not grow with the same rate. I omitted the first line of the measurement because it is not relevant (vlc was being started).

[Bug 1884850] Re: Xorg server uses unacceptably large amounts of memory (and keep growing)
Hi Daniel, responding to your comment: In my years of using Linux desktop (in particular, XFCE), I have never experienced memory explosion caused by Xorg server like what I described in this bug report. Please allow me to be a bit candid here. It seems like the newer versions of desktop software (which could mean one or more of these: Xorg, firefox, Libre Office, XFCE and/or MATE, ...) leads to significant bloat in memory usage. This is to the point that a very capable laptop (with >= 8 GB of RAM) would perform poorly because of memory thrashing today even when our usage pattern is not changed over the years (at least I feel so). I'll back this up below. I still have a desktop computer running Debian 8 and XFCE.

[Bug 1884850] Re: Xorg server uses unacceptably large amounts of memory (and keep growing)
Thanks. I am testing XFCE desktop for now. A brief comment on XFCE experience. The starting size of Xorg process under XFCE is ~100-130 MB, but after 10 days of usage with mostly Firefox & terminal windows (multiple windows for each app, and sometimes pdf viewer [atril]) it grew to 270-300 MB. I have some data collected by xrestop, ps, if you want it. Let me know what kind of data would help. In a prior session where I was still using LibreOFfice (again, with multiple windows, but nothing is a huge document or complicated doc with lots of graphics), the memory usage grew to over 800 MB usage. And xrestop indicated libreoffice was consuming nearly 200 MB of pixmap memory just before I closed it! Any direction to help narrow down the source of large memory consumption would be appreciated.

[Bug 953440] Re: Screen corruption observed randomly
Thanks for the reply. I launched the live CD version of the daily build on the machine. The display was changed to a different monitor with ordinary 1280x1024 resolution. Sorry, it is not practical for me to repeat the old setup and rerun the test. I see that the nouveau driver is indeed loaded on that machine, so this is an opportunity to try out the new version of the OS. I am yet to check whether the screen corruption would occur in this setting. But I am frustrated by the flashy animations of windows etc, which I suspect is due to compiz (I can see compiz process using lots of CPU). How do I disable this? Sorry this is OOT, but if you (@Christopher) can help, I may be able to test out some more without the flashy compiz stuff.

[Bug 559163] Re: Dell Latitude D600 hangs on wakeup from suspend
This bug is probably not going to be resolved, given the lack of interest in solving the problem, and the oldness of the video card. If you use crunchbang linux, there is actually a simple workaround which I found to be working. I disabled the kernel modeset altogether (so it reverts back to user-mode modesetting. which was the old way of doing things). This is done by modifying the kernel command-line parameter (GRUB_CMDLINE_LINUX ) in /etc/default/grub: GRUB_CMDLINE_LINUX=radeon.modeset=0 After that you execute `sudo /usr/sbin/update-grub' and reboot. Try it and let us know. On my laptop (which is actually a inspiron 600m with D600 motherboard), suspend to RAM and resume worked fine. I would be curious to see if this would work also for ubuntu.

[Bug 953440] [NEW] Screen corruption observed randomly
Public bug reported: I am using nouveau driver to drive a ViewSonic LCD display that has HD resolution (1920x1080) on this computer. On random occasion, usually after unlocking a screen saver, the screen will look corrupt. Symptoms: 1) desktop background is always corrupted 2) Letters from some fonts would become garbled. To work around (1), I could restart nautilus. But for the other symptom, I don't know. Background: I originally installed this when I had a different external display (and I was using proprietary nvidia driver included in Ubuntu 10.04 LTS). The original resolution was 1600x1024.

Hi Bernt: I recently installed Debian 6.0.2 (Squeeze) on my laptop. I think this distro runs smoothly on this laptop. Exception is the firmware for intel iwlwifi, which must be installed separately (not a big deal). I am using kernel 2.6.38 from squeeze-backports to get rid of flickering problem existing in 2.6.32 kernel line. I probably should write a fuller report in ubuntu forums instead of here. I just want to give you some lead if perhaps this would help you too. I love Ubuntu and the efforts made by Canonical to popularize linux.

I have been using 64-bit Ubuntu (8.10, 10.04 LTS) in Thinkpad T400 with Intel graphics. They are fine in general. There are issues here and there--some could be annoying.

Hmm... nobody responded. I found a few posting on Ubuntu Forums which might or might not be relevant: http://ubuntuforums.org/showthread.php?t=1467927 * This one says flickering about once a minute. I did not experience this. I did experience occasional flickering but not as often as once a minute. The flicker is very quick and the display goes back to normal. I was afraid if this was my hardware error; but now I suspect it is probably software-related. * The solution mentioned there (about disabling RANDR service) does not apply to me. Apparently it is for KDE-based Ubuntu desktop; I am using GNOME. * But there is a mention about a bug in Lucid intel driver (see post #10): For what I've read, there's a bug on Lucid with the Intel Corporation Mobile 4 Series Chipset, and it hasn't been fixed, so we're out of luck.

[Bug 777956] [NEW] X display with Intel i915 driver occasionally goes blank after resume from suspend
Public bug reported: Binary package hint: xorg I have had Ubuntu 10.04 on my laptop (see details in attachments) since September 2010. I have been using kernel modeset. This one has a hybrid Intel/ATI display. I disabled the ATI one and only used the Intel. Here is the relevant lspci output: 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) 00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) For a while this laptop suspended and resumed with no problem whatsoever. I use this laptop as a work machine that I suspend/resume often (once or twice a day if not more). Recently (for a few months) the laptop sometimes wake up with a bizzare behavior on the LCD display: it flashes a bright light then the LCD went black. Never to recover until I rebooted the laptop. Trying to suspend and resume again won't help. The result from dmesg etc came from a fresh reboot, so it might not show anything there. Once I tried to scavenge for debug info or other logged problems when this happened by gathering all the dmesg, /var/log/kern, /var/log/messages or /var/log/Xorg.0.log -- they did not contain anything useful AFAIK. I can attach them if you want. The difficulty is that this bug would not appear consistently. It only appears randomly and I can't tell when it would happen. I am filing this bug report just in case other Thinkpad users with intel integrated graphics also experienced similar problem (or if it has been reported elsewhere). I have a suspicion that perhaps some kernel update in the past caused this bug, since it never happened before. Another point to consider: from time to time I would use xrandr to duplicate or extend the display to external VGA projector. (`xrandr -q' is usually all I did and the magic is done). Not sure if this has to do with the problem said above.

And it is suspended and resume day after day (and brought with me to home and office); and the OS/desktop is not typically restarted after 1 month or more.

Felipe, what you did in giving firefox backtrace is almost complete, but it still does not provide useful information yet. I think you don't need to issue continue, but rather you need to follow step 6 in the wiki page that you mentioned. The output can be long; so you might want to issue: set logging file /tmp/gdb.log set logging on (/tmp/gdb.log can be replaced by another file name of your choice) before doing the backtrace dump. Then publish the /tmp/gdb.log to this bug database. The backtrace info is what the developers are after, I believe.

[Bug 316460] [NEW] WPA2 Enterprise wireless connection is often lost by itself
Public bug reported:
Binary package hint: wpasupplicant
I installed 0.6.7 today on my laptop. It indeed resolves the problem
with Compound_MAC problem in:
https://bugs.launchpad.net/ubuntu/+source/wpasupplicant/+bug/304126
I configured and built my wpa_supplicant with dbus support (for later
uses, just in case), and only wext driver, which is the one used for my
laptop. I put wpasupplicant as the first suspect of this bug, since it
happens only with WPA2 Enterprise kind of encrypted wireless network.
However I still have a problem that I had with 0.6.4 earlier, namely
that the connection often breaks by itself. This is my
wpa_supplicant.conf section (with no username and password), using WPA2
Enterprise connection.
network={
ssid=W-M_Wireless_Encrypted
scan_ssid=0
key_mgmt=WPA-EAP
eap=PEAP
phase1=peaplabel=0
phase2=auth=MSCHAPV2
identity=ident...@wm.edu
password=PASSWORD
}
My campus website gives the following tech info:
SSID:W-M_Wireless_Encrypted
Encryption: WPA2 Enterprise
802.1x/EAP Type: PEAP (Protected EAP)
Authentication: MS-CHAPv2
The config that I used above could successfully authenticate my laptop
on the encrypted network, and get me the IP address via DHCP.
When my connection is lost, I noticed from the debug file
(/var/log/wpa_supplicant.eth1.log) that the BSSID that I am associated
to is often blacklisted, and sometimes re-whitelisted later. But when
this happened, the connection could not be resumed. I don't understand
something here... This seems to happen randomly, and usually after some
period of idling. Not knowing whether scan_ssid is a culprit, I have
tried scan_ssid=1 also, but it does not matter. The SSID is not hidden
anyway.
When the connection is broken, the `wpa_cli status' and `iwconfig' still
show good and valid connection, but I could not even ping outside my
laptop.
Any help will be appreciated.

[Bug 314424] [NEW] Firefox 3 memory use explodes by itself randomly
Public bug reported: Hi, I noted that the recent versions of Firefox (3.0.4 and 3.0.5) would randomly explode in terms of memory use. It happened on at least the following two machines: * laptop, Dell Lattitude D600 (768 MB RAM, Pentium M), OS: Ubuntu 8.10 with firefox 3.0.4 and later 3.0.5 * desktop, Dell Dimension 8250 (2 GB RAM, Pentium 4), OS: Ubuntu 8.04 with firefox 3.0.5 This problem happened to me today on the desktop, in which `top' reported the following memory use: PID USER PR NI VIRT RES SHR S %CPU %MEMTIME+ COMMAND 10021 wirawan 20 0 109m 1684 1668 R 100 0.1 1472:19 ld-linux.so.2 9675 wirawan 20 0 2049m 1.7g 6312 S2 87.9 22:23.60 firefox I typically let firefox run for many days on this machine, as this is a desktop machine in office. The computer is also never suspended. Fortunately the computer has 2G of memory so I could still manage to bring down firefox without injuring the whole system.

Unfortunately I already killed everything by now. I am sure that this problem would appear again, and if it does, I will post more information here. Firefox was upgraded yesterday to version 3.0.5, so it has been running for less than 24 hours. Other than the PDF plugin, and Ubuntu standard plugins (vlc, mplayer, divx, quicktime), I don't have any other plugins. Specifically, this firefox is not equipped with Adobe Flash plugin. The last pages that I left on, (if I am correct, based on the firefox's sessions restored), are: * http://www.bestbuy.com/site/olspage.jsp?id=pcat17071type=pageinitialize=falsesp=-bestsellingsort+skuidnrp=15iht=nlist=ysc=Globalst=under_20pageusc=All+Categoriesks=960prids=cp=3qp=_requestid=556654 * http://www.chem.ucla.edu/dept/Faculty/dxn/pages/teaching.html * http://www.pcc.qub.ac.uk/tec/courses/f90/stu-notes/f90-stu.html * http://support.dell.com/support/edocs/systems/dim8200/codes.htm I don't recall how much memory this firefox uses last night, before this exploded today. Probably I should make a simple cron job to collect the stats of firefox, eh? Usually the memory explosion happens when the computer is idling and screen saver is running. I wonder if there *is* indeed correlation between these two. In the past, I never encountered this kind of memory explosion in the past with firefox 2, if I remember it correctly. Another thing that I suspect is whether heavy-duty pages such as Yahoo mail (the new interface) is a culprit also. I cannot confirm this yet. If anyone ever experience this kind of problem, please add your comment. It is very annoying that now firefox becomes a time bomb in my computer. What I do temporarily as a workaround in my laptop is to add the following limitations on its startup script (/usr/lib/firefox-3.0.5/firefox.sh), just before the execution of firefox binary: # Limiting virtual address space, data segment, and resident memory ulimit -d 50 ulimit -v 50 ulimit -m 25 This is *not* without its own peril, as I observe that firefox's vmsize can grow quickly although the real rss is not that big.

If it succeeds, then suspend will continue as usual. This would be a nice feature, as applications don't have to always force its will to g-p-m (i.e. inhibiting suspend). It is not critical for a playback to be paused automatically if we want to suspend the computer. But of course there are circumstances where we don't want g-p-m to suspend no matter what, such as formatting disk, burning a CD/DVD, etc. -- Multiple applications have stopped the suspend from taking place. vlc : Playing some media https://bugs.launchpad.net/bugs/290753 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi everybody, There has been no further discussion from anyone for a little while; new posts seem to repeat the existing bug description. I am surprised that such a long bug report hasn't be acted upon promptly, although the fix is easy to make (albeit being a dirty workaround): This dire situation we are having with Dell laptops can be easily fixed if the patch proposed in comment #142 is incorporated into the current file atkbd.c in the Linux kernel, by adding an additional record in the atkbd_dmi_quirk_table[] array using the second commonly-found DMI string match: Dell Computer Corporation, in addition to the Dell Inc. string. This is dirty indeed, as we have two records of similar things. But this would get rid of the problem for virtually all Dell users. Could one of the Ubuntu developers do this for us, please?

[Bug 290067] Re: switch user or switch to console failes on first try in intrepid
This bug also happens to me. I am attaching my Xorg.0.log here. The log includes log entries after four Ctrl+Alt+Fn strokes (n = 1..6). Stroke #1 is the first attempt to switch to a VC (virtual console). It failed in the following way: the corresponding virtual console (VC) appeared for a split second, but then the X screen reappeared. If this happens, retrying it (stroke #2) immediately always succeeded. Stroke #3 also failed: it took place several minutes apart (I have no idea about the exact time interval) from the strokes #1 and #2. Stroke #4, a retry of stroke #3, also succeeded. In brief, after one failure, other following attempts would succeeded if they are closely spaced. But then if we don't switch to any VC for a period of time (maybe several minutes), then attempting to switch to one of the VCs would fail as I descibed above.

[Bug 310798] [NEW] Suspend denied by gnome-power-manager, saying that action stopped by vlc
Public bug reported: Binary package hint: gnome-power-manager Version references: Xubuntu 8.10 (Intrepid Ibex), gnome-power-manager version 2.24.0-0ubuntu8.1, vlc/vlc-nox version 0.9.4-1ubuntu3 . Hardware reference: Dell Lattitude D600 (Pentium M, 768 MB RAM). I am filing this bug against gnome-power-manager first, but the blame could lie on vlc. I am playing an M3U list containing a mix of OGG and MP3 files with vlc (the GUI one). After I stopped the vlc (using stop button), I tried to suspend using the usual key (Fn+Esc). Then a pop up showed on the bottom of the screen, saying this: Request to do policy action Multiple actions have stopped the policy action from taking place. vlc: Playing some media. vlc: Playing some media. (yes, the last line is duplicated). This is the first time it ever happened to me. Now, I cannot suspend the machine via Fn+Esc, and pressing power button (which usually brings up the suspend-hibernate- poweroff-reboot prompt) also pops the same message like above. What's even more silly, is that the message repeats in new pop up windows if I press Fn+Esc again and again. (But that's not the focus of my bug; I just want to bring that up.) I then closed the vlc program gracefully. Yet the gnome-power-manager still denies the suspend for me after vlc quits. What's going on here? I remember that last time this situation happened, the denial was removed when I closed vlc (but I don't remember whether it was on pause or on stop.)

[Bug 281526] Re: Firefox freezes with 100% CPU after resuming from suspend
I can confirm this problem on one of the laptops that I used. IT is a Sony VAIO PCG-FXA53 with AMD Athlon XP 1400+ CPU, 512MB RAM. The other laptop (Dell Lattitude D600) never experienced this kind of problem. I notice that usually either firefox or both firefox/Xorg combination consumes the CPU after suspend to RAM. Often the problem can be cured by closing some web pages. I notice that the following pages are the culprit (again, I still cannot notice a definite pattern): * mail.yahoo.com (new web mail) * mail.google.com (standard AJAX interface) * perhaps weather.com, skymall.com I will write more then things become clearer to me.

I installed the newest gnome-power-manager (2.24.0-0ubuntu8.1) on my Dell Lattitude D600.

System: Intrepid Ibex. See comment #126 for more hardware/software
detail.
* Commenting suggestion from Jérémie Laval:
https://bugs.launchpad.net/ubuntu/intrepid/+source/linux/+bug/285323/comments/51
-- I also found that this trick did not work for me (as Saïvann
Carignan mentioned in comment #53)
* Confirming Endolith's 3rd observation in comment #56 above: hald-
addon-dell-backlight is taking much CPU (~48%; or if I have firefox as
the main window: X ~ 32%, hald-addon-dell-backlight ~ 14-18%, firefox
~10%).
* Confirming comment #91 by Daniel Knitt-Frank: When I got locked due
to Fn+up/dn, then when I used Ctrl+Alt+F{n} (n = 1..6) for the first
time (as the suggested for workaround), the X screen somehow pops back
in before I even pressed Ctrl+Alt+F7. I had to press Ctrl+Alt+F{n} then
Ctrl+Alt+F7 again to fully restore the functionality of keyboard (just
to be safe). Weird.
Also related, probably: after the suspend and resume, sometimes the LCD
brightness slider would not work anymore. But later on (don't remember
whether I suspended again or not in between) it worked again. I may need
to open a separate thread for this bug. But for now I just want to make
a comment on that.
My DMI vendor string is also Dell Computer Corporation, so I'm out of
luck with the fix already in the kernel. When will somebody act upon
this?

I have not tested earlier or later versions. And specifically it affects network-admin program, which allows user to specify network parameters via its GUI. In brief, the default wireless security mode that is written to /etc/network/interfaces is restricted. In my case, this is the reason why my laptop could not connect to my wireless station unless I disabled the WEP! After I discovered this problem, I inserted the following text manually in /etc/network/interfaces : wireless-keymode open and, after `sudo ifup eth1', the wireless connection worked fine.

Public bug reported: I don't like the way suspend problem reported in Ubuntu, as shown in the attachment (supplied in a later submission): Suspend Problem Your computer failed to suspend. Check the help file for common problems. That's it! I really wish that this applet provides, at least, a button saying Detail..., through which, a window can be displayed to show the problem detail.

Public bug reported:
Binary package hint: libc6
I used Ubuntu 7.04 on x86 system (Pentium M), and updated the libc
package to version 2.6: (2.6-3ubuntu2). The error described below also
appliled to glibc 2.5, IIRC.
I found that the following C program won't print the correct number of
digits:
#include stdio.h
int main(int argc, char *argv[], char *env[])
{
printf(%#.4g\n, 912.98);
return 0;
}
The output should be 913.0, but my Ubuntu box shows 913. (no
trailing zero). The alternate format, according to the C standard,
should print out the trailing zeros after decimal point.
This error is shameful and severe! I tried on different systems (Fedora
5, Fedora 6, SunOS, CentOS), none of them show this sickness.

Now what's wroing? I believe that the error is due to the following lines in file e_redraw.cpp: 473 char num[10]; 474 475 MoveStr(B, 0, W-Cols, s, SColor, W-Cols); 476 sprintf(num, %s %d, CCharStr, ModelNo); We only have TEN characters available in the num array. Is this enough, though? NO! I noticed in line 424--431 of the same file, that CCharStr contains exactly six characters (not counting the terminating NULL). As a consequence, for buffer /tmp//.pl above, whose ModelNo == 101, we have 1+6+1+3 = 11 non-null characters plus one NULL terminating character. This is just FATAL! So to solve the problem, just allocate a larger buffer for num. In my case, I'd rather be wasteful and safe, so I will replace line 473 to: 473 char num[32]; That should be large enough for any integer value of ModelNo and string of CCharStr.

[Bug 124573] xmgrace with LessTif crashes when Esc key is pressed on menu
Public bug reported: Binary package hint: lesstif2 I am using Ubuntu 7.04 . The LessTif package that I used was: lesstif2 version 0.94.4-2 . The xmgrace version was 5.1.20-1, although I could reproduce the same bug exactly with 5.1.21-1 also. How to reproduce: Try bringing up the xmgrace program, then play around with menu with keyboard. Say, press Alt+F , then Right or Left . The menu will be stuck (would not navigate anymore with keyboard). That's bug #1. So, you are desperate, right? Try pressing Esc now. If it did not do anything, try it again. BOOOM! The program will crash and xmgrace will print the following in the stdout/stderr: [quote] Oops! Got SIGSYS Please use Help/Comments to report the bug. NB. This version of Grace was compiled with LessTif. Make sure to read the FAQ carefully prior to reporting the bug, ESPECIALLY is the problem might be related to the graphical interface. Aborted (core dumped) [/quote] An easier way to reproduce the bug is this: 1. bring up xmgrace 2. press Alt+E 3. press Esc , and BOOM!! I would note that I recompiled the same grace package with OpenMotif 2.3.0, and these problem disappear altogether. So, whose fault is this? I would say, but not definitely, LessTif. ** Affects: lesstif2 (Ubuntu) Importance: Undecided Status: New -- xmgrace with LessTif crashes when Esc key is pressed on menu https://bugs.launchpad.net/bugs/124573 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 124573] Re: xmgrace with LessTif crashes when Esc key is pressed on menu
This might give you a hint of what's the problem is: The items listed on the menu bar are: File, Edit, Data, Plot, View, Window, and Help. The crash abovementioned happens when you press any of the Alt+key to access the menu items and Esc afterward, with the exception of Alt+F (File menu). I tried many times, and the program did not crash at all. So it may be something related to the internal representation of the menu list, or what.
