[Bug 1069265] Re: Compiz hangs at first click anywhere on desktop - can work around by deleting .compiz/session/* first.
Hello all! Executive summary of the verbose text below: * I can confirm the same problem, and also that deleting anything under ~/.compiz*/* resolves my problem temporarily * I don't believe it's related to graphics adaptor drivers, as my Thinkpad T500 with dual graphics has the exact same problem when using the on-board Intel graphics with no proprietary driver. * I believe the problem *MIGHT BE* related to systems being upgraded from previous Ubuntu versions * It *MIGHT ALSO BE* related to use of CCSM (Compiz Config Settings Manager) and other tools that are tweaking settings and hence possibly causing problems by setting parameters that are not 100% compatible. I have the exact same problem as you report here! My laptop is a Lenovo Thinkpad T500, pretty plain common, I'd say, and Thinkpads also have great Linux support in general. I've got dual graphics consisting of a dedicated ATI Radeon card and an on-motherboard Intel chip. I've configured BIOS to use only the on-board Intel graphics, mainly because the laptop's using less than half the power (really: battery is lasting double the time!), and I don't use any proprietary driver. Still, I'm reproducing the exact problem you're reporting, and my resolution has also been the same :-) Honestly, I don't think the problem is related to graphics drivers, but I haven't had the time to do any further debugging. However, I confirm that deleting any directories and files under ~/.compiz*/* is also resolving the problem on my side. Furthermore, I may add that I'm usually working 1-2 weeks without rebooting my laptop (just closing the lid, making the computer go sleep), and I very rarely have problems even though I every day plug/unplug external monitor at my workplace (no docking, just plain VGA cable plugged/unplugged), and also when I'm using projectors in meeting rooms etc. Even though I used to have more trouble (especially under Ubuntu 11.x series with Unity), 12.10 is rather stabile except for the boot-up problem. If I'm able to type into a terminal window under Unity after boot, I'm usually able to fix the problem temporarily by performing $ compiz --replace However, it will crash again, until I first delete the file structure under ~/.compiz*/* and replace compiz again. If I'm not able to type into a terminal window under Unity (the same tty, normally tty7), the same procedure does NOT work from e.g. tty1 (typically using CTRL+ALT+F1 to fix problem). In this case even the following doesn't help: $ killall -9 compiz $ DISPLAY=:0.0 compiz --replace In these cases, I have 2 options: 1) sudo shutdown -r now 2) sudo service lightdm restart The problem for both alternatives is that any open application under the existing session will be killed as well. (This isn't a huge problem when the compiz/unity crashes just after reboot, but was really annoying when it used to crash in the middle of the day, giving me no alternative but to kill all running applications including a couple of virtual machines under VirtualBox.) Also, I suspect that our problem is related to systems being upgraded from earlier Ubuntu distros (mine comes from 10.10, as far as I remember) and/or is related to use of ccsm (Compiz Config Settings Manager). Sorry for the long texting, and I'm happy to provide logs etc. if anyone interested. (I'm currently creating a full image backup and plan to reinstall a clean, plain 12.10 install to see if that makes any difference.)

[Bug 943083] Re: Unable to fetch children: No such interface `org.ayatana.bamf.view'
I have a general problem whenever re-booting Ubuntu 12.10; Compiz seems to always crash, and I'm losing the launcher, dash, window decorations, ability to switch desktops or even window focus. If I'm able to type into a terminal under unity (still default tty7), I'm usually able to (temporarily) fix the problem by typing $ compiz --replace However, if I have to switch to tty1, it's not working with the same $ DISPLAY=:0.0 compiz --replace (not even if I do a killall -9 compiz first) In this case, I have to do the following from tty1: $ sudo service lightdm restart Sorry for the long intro, but here's the link to this very issue; Whenever I'm able to get into a terminal window under unity and fix the issue by 'compiz --replace ', the terminal window is printing out lots of these ayatana/bamf warnings afterwords. Also, a few ERRORs are printed: ERROR 2013-02-19 11:07:36 nux.gestures_subscription GesturesSubscription.cpp:364 Failed to set Geis subscription configuration com.canonical.oif.drag.threshold ERROR 2013-02-19 11:07:36 nux.gestures_subscription GesturesSubscription.cpp:364 Failed to set Geis subscription configuration com.canonical.oif.drag.timeout ERROR 2013-02-19 11:07:36 nux.gestures_subscription GesturesSubscription.cpp:364 Failed to set Geis subscription configuration com.canonical.oif.pinch.threshold ERROR 2013-02-19 11:07:36 nux.gestures_subscription GesturesSubscription.cpp:364 Failed to set Geis subscription configuration com.canonical.oif.pinch.timeout ERROR 2013-02-19 11:07:36 nux.gestures_subscription GesturesSubscription.cpp:364 Failed to set Geis subscription configuration com.canonical.oif.tap.threshold ERROR 2013-02-19 11:07:36 nux.gestures_subscription GesturesSubscription.cpp:364 Failed to set Geis subscription configuration com.canonical.oif.tap.timeout ERROR 2013-02-19 11:07:36 nux.gestures_subscription GesturesSubscription.cpp:364 Failed to set Geis subscription configuration com.canonical.oif.rotate.threshold ERROR 2013-02-19 11:07:36 nux.gestures_subscription GesturesSubscription.cpp:364 Failed to set Geis subscription configuration com.canonical.oif.rotate.timeout Please NOTE that if I leave my computer (Lenovo Thinkpad T500 using the onboard Intel graphics adaptor without any proprietary driver) on for a week or more, just closing the lid when moving, I usually don't have any problems -- even if plugging/unplugging external monitor/projector. When I'm rebooting, however, the problems almost certainly will occur. What I've found out is that deleting all compiz logs (which I can do from tty1 before restarting lightdm) seems to fix the problems crashing compiz. I.e. what I do is basically 1. switch to tty1 and log in as myself 2. rm -rf ~/.compiz (in order to recursively delete session logsthere might also be ~/compiz-1 and so on -- delete all!) 3. sudo service lightdm restart 4. log in using the standard greeter again Note that this procedure (restarting lightdm) has the negative effect of killing any open applications, including my virtual machines running on top of Ubuntu. Hence, it's a procedure I try to perform just after restarting the computer, since the system seems a lot more stable after I've done this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/943083 Title: Unable to fetch children: No such interface `org.ayatana.bamf.view' To manage notifications about this bug go to: https://bugs.launchpad.net/bamf/+bug/943083/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 872054] Re: Cannot shutdown/restart with multiple users logged in
*** This bug is a duplicate of bug 861171 *** https://bugs.launchpad.net/bugs/861171 This problem still persists in 12.04 and 12.10, at least with Unity (if that matters). My solution is to shutdown via a terminal session, which works well (as long as sudo is used). Work-around: 1. Open a terminal 2.

[Bug 861171] Re: Shutdown from greeter does nothing when multiple accounts open
I'd say go for your Alt A, Robert, and I agree that an authentication dialogue is better than the vanilla conf dialogue exactly like you say; This will definitely make the general wife or brother pause to think 3 seconds before shutting down killing other sessions. I guess that power button is accessable to the common user in about 98% of all use cases, and therefore I also agree that any user should be able to perform a proper shutdown if he/she is working locally (either from greeter or from session). HOWEVER, this makes it VERY important to keep in mind what Matthew says about really being pushy on the user...really trying to make him understand that this is serious business. (This learning also comes from Windows where quite a few of us have lost work due to the fact that wife/brother actually shut down the computer without even thinking about other users. Well...maybe not THAT many of us, since I guess Windows in general is considered a 1 user system in more cases than unix.) In the mean time (work-around): For anyone with slight tech knowledge (like myself, and I emphasise slight in this sentence), they are likely to have sudo permissions and be able to perform 'shutdown now' from a terminal anyway. Thanks a lot to you guys in the team who actually FIX things for all of us others who're just whining!! :-) alfs -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/861171 Title: Shutdown from greeter does nothing when multiple accounts open To manage notifications about this bug go to: https://bugs.launchpad.net/indicator-session/+bug/861171/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 740126] Re: Disabling an output can cause vblank events to be missed
Hello, I'm running on a ThinkPad T500 with dual video. Currently have been running with the build-in Intel graphics adaptor (due to battery life). I may switch to the external ATI Radeon 3850 (I think that's what my laptop has...) and test if that resolves the problem. One theory I have is that the problem is related to the Compiz process providing 3D graphics for Unity, and that this is related to the HW we are running; i.e. if we run the Intel on-board graphics adaptor, it might not have 3D support in HW, hence demanding other things from the SW than if we run on 3D enabled graphics adaptors. Does this sound as a possibility, anyone?? My solution to the problem (when coming back to my laptop with frozen screensaver) has been to press CTRL+ALT+F1 and then log in to the console in tty1. From here, I run ps -ef --sort time to see which processes have been running for a long time. 1) kill pid of gnome screen-saver does not help -- doesn't even remove the screensaver photo from the display even though the process dies. 2) kill pid of compiz does not kill the process -- no change 3) kill -9 pid of compiz does actually kill compiz, and at this point pressing CTRL+ALT+F7 (or F8) takes me back to the Gnome session, which is now flashing a bit, then refreshing and coming up again, seemingly normal. Most of the times, I'm able to get back into my session with all applications still running after step 3) above. However, it has also happened that I got a new, blank session with no apps running. My 5 cents today is that this is a problem related to compiz and 3D rendering, and that it might be related to the graphics adaptor used, including whether the computer is equipped with 3D suppot in HW.

[Bug 778387] Re: Unity freezes when the desktop should be locked due to inactivity
I've been running 11.04 one week (default upgrade by Update Manager from 10.04) on ThinkiPad T500, and I have the same problem; After leaving my laptop for a while, sometimes (approx. once a day), the system hangs when trying to resume; - Screen saver picture shows beautifully - Mouse pointer shows and moves with mouse - Nothing brings back the login password input box. (Disabling password protection in the screen saver doesn't help, the screensaver picture and mousepointer still shows with no response) - Starting a new session from tty1 and running ps -ef then kill on the gnome screen saver process doesn't even remove the screen saver picture when pressing CTRL+ALT+F7 or F8 (depending on original session). - Trying kill on several processes, I found that kill -9 on compiz was the only thing that could unlock the hang/freeze. Note that in 2 occasions, this actually kept my existing login session, not killing running applications/virtual machines, whereas one time I lost the entire session and all context/running apps. Also, I notices one time that a new session was kicked off in tty8 even though the one I killed was running from tty7. - I can't see any pattern regarding network (wired eth vs wlan vs. nothing) or power (battery vs. power supply) or running apps (other than the fact that Unity has been GUI/windowing manager) My T500 laptop has dual graphics adaptors; An internal Intel chip (which I am using, locked by the BIOS setup to save power and extend battery life) and a ATI Radeon adaptor (PCI) which I have disabled, and I've currently not loaded legacy drivers. It might be that the internal Intel chip is not acceptable for accelerating 3D graphics...however I never realised any problem with the previous Ubuntu 10 releases (however not using the effects very much) or with Windows 7 for that sake (the Aero effects). It seems to me that this problem is related to compiz, and also note that default kill will not actually do anything, it's necessary to add -9 to the kill entry to have any reaction. Thanks for a fantastic effort in order to deliver both a very good desktop Linux version and support!
