Screens; a choice between 1920x1080 WLED 1920x1080 RGBLED IPS The IPS screen only comes with an NVIDIA Quadro 2000M with 2GB GDDR3, The regular screen comes with these choices of video card: AMD FirePro M5950 Mobility Pro with 1GB GDDR5 dedicated memory NVIDIA Quadro 1000M with 2GB GDDR3 dedicated memory NVIDIA Quadro 2000M with 2GB GDDR3 dedicated memory The price difference is substantial. Considering that my usage is nothing more stressful than KDE eye-candy and mplayer, is the IPS screen worth the extra price? OTOH the machine has VGA, HDMI and DisplayPort as well as internal screen and I believe the ATI can drive all 4 at the same time whereas the nVidia is pick any two. Up to 4 screens might be more useful than outright performance. I don't think it is. When I bought my XPS (a year and a half ago) the RGBLED screen was c. £150 on top of what was a rather expensive machine by my affordability standards. Perhaps it was an early version back then, but although it was claimed by those who bought it that the RGBLED has somewhat superior picture quality, it also had 2 more drawbacks besides the price: 1. You need to calibrate the monitor to get best picture and may need to repeat that every now and then. 2. It will suck your battery dry (much?) faster than the WLED. If you're always on mains then the latter may be less of a problem. A word of warning: the 1920x1080 resolution on a 16 monitor is *small*. Trying to read a typical website or even the content of my desktop menu would cause eye strain! Ha! Fantastic picture if you just want to watch videos in full 1080p HD, but if you are also thinking of productivity you may need to readjust your desktop settings to make reading comfortable. On e17 I had to change the Scaling setting to 80 DPI. A final note about Dell's build quality: This is meant to be a top of the range laptop. However, there are no substantial rubber stops to keep the screen surface away from the keyboard. Even with 3 additional self-adhesive rubber stops that I added, the keyboard is still touching and scratching the screen. For the sort of money I paid to buy it I would expect some more thought to have gone into the design and build of it. I guess all laptops these days are being churned out of some Chinese sweat shop, but for the money I expect a better product. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

On Saturday 16 July 2011 17:53:48 Stroller wrote: A bit of a long shot, this, but has anyone got any older Portage snapshots kicking around, by any chance? I have a box which hasn't been updated in 2 - 3 years. It would normally be easiest to format and reinstall, but in this case the box in question is a PS3 which was installed using the experimental PS3 stages which are (I think) no longer available. I'm pretty sure this machine has some PS3-specific hacks applied, so I think an attempt to upgrade the hard way is worthwhile. If it doesn't work I'll probably try Debian, or something. I have no illusions that attempting this *will* be a pain the ass, because in the past I've updated machines which have been ignored for 18 months, and that required lots of manually digging in the Portage CVS attic and copying files into the local overlay by hand. So if anyone has any Portage snapshots that are sufficiently old left lying around from an old install, it would save me that grunt work. Alternatively, if you, too, have a machine that hasn't been updated a long time, maybe you'll be able to help me by tarring up a copy of the Portage tree. Thanks for looking, Stroller.

No, you just need a newer portage, probably a version = 2.2. This seems to be safe and is often suggested here on this list. Although there are frequent updates and I wonder if some big bug might slide into portage one day. If you want to do so, put sys-apps/portage- ** in /etc/portage/package.accept_keywords. Or something like =sys-apps/portage-2.2.0_alpha45 to install this version only, but I guess when it moves out of the portage tree it will be downgraded, so you'd need to put the ebuild into your local overlay then. And by the way, what is the use of 'xorg-drivers' package ? I think it's just some sort of meta package pulling in the real drivers. At least the output of equery files xorg-drivers is empty. Wonko

It's true that the IPS does have a fantastic viewing angle. I only started seeing bothersome colour shifts at about a 70degree angle viewed from the 10 o'clock position. Which is all great except that no-one in their right mind looks at a notebook from that acute angle. And I've never needed hugely accurate colour reproduction in 20 years, so I doubt that will change either anytime soon. My current machine is 1920x1200 with a regular display, and it's plenty good enough for me so I can't honestly say I see a need for the latest and greatest. But there's always a chance someone who's used one for a while will report significantly reduced eye strain or similar (impossible to detect this in the first short trial), hence my original question.

Screens; a choice between 1920x1080 WLED 1920x1080 RGBLED IPS The IPS screen only comes with an NVIDIA Quadro 2000M with 2GB GDDR3, The regular screen comes with these choices of video card: AMD FirePro M5950 Mobility Pro with 1GB GDDR5 dedicated memory NVIDIA Quadro 1000M with 2GB GDDR3 dedicated memory NVIDIA Quadro 2000M with 2GB GDDR3 dedicated memory The price difference is substantial. Considering that my usage is nothing more stressful than KDE eye-candy and mplayer, is the IPS screen worth the extra price? OTOH the machine has VGA, HDMI and DisplayPort as well as internal screen and I believe the ATI can drive all 4 at the same time whereas the nVidia is pick any two. Up to 4 screens might be more useful than outright performance. I don't think it is. When I bought my XPS (a year and a half ago) the RGBLED screen was c. £150 on top of what was a rather expensive machine by my affordability standards. Perhaps it was an early version back then, but although it was claimed by those who bought it that the RGBLED has somewhat superior picture quality, it also had 2 more drawbacks besides the price: I *can* see a difference with the RGBLED screen (see why answer to Stroller where someone in the office got one today), but its not a compelling difference and not big enough to make me go Wow! yet 1. You need to calibrate the monitor to get best picture and may need to repeat that every now and then. I will likely never do this :-) Mostly coz I'm lazy... 2. It will suck your battery dry (much?) faster than the WLED. If you're always on mains then the latter may be less of a problem. Mostly on mains, but I'd like to stay at more than 2 hours battery life from a full charge for 2.5 years A word of warning: the 1920x1080 resolution on a 16 monitor is *small*. Trying to read a typical website or even the content of my desktop menu would cause eye strain! Ha! Fantastic picture if you just want to watch videos in full 1080p HD, but if you are also thinking of productivity you may need to readjust your desktop settings to make reading comfortable. On e17 I had to change the Scaling setting to 80 DPI. Currently I have 1920x1200, 96dpi and konsole fonts set at 8pt. I'm used to people looking over my shoulder saying how the blazes do you read those tiny letters? A final note about Dell's build quality: This is meant to be a top of the range laptop. However, there are no substantial rubber stops to keep the screen surface away from the keyboard. Even with 3 additional self-adhesive rubber stops that I added, the keyboard is still touching and scratching the screen. For the sort of money I paid to buy it I would expect some more thought to have gone into the design and build of it. I guess all laptops these days are being churned out of some Chinese sweat shop, but for the money I expect a better product. I can't honestly fault this XPS's build quality. The palm rest area has warped, but it does run hot almost 24/7. The keyboard always felt a tad lower quality than it should have been, but did take 2.5 years for the legends to start wearing through. From what I've seen, the Precisions are better (there's quite a lot in the office of varying ages). They are almost as good as ThinkPads - not as good, but close. -- alan dot mckinnon at gmail dot com

Running /etc/init.d/nginx ineed gives me fsck localmount dhcpcd net.eth0 net.eth1 net.lo I guess this means that all the net.* interfaces have to be up for nginx to start. Wouldn't it be more logical to require only one (like the loopback interface) to be up? The problem is that if I stop net.eth1 and start nginx it tries to start net.eth1, which I'd rather it did not do. Is there any way to avoid this? Thank you! Best regards, Giedrius Kudelis

Oddly VGA is the only common interface on all my display devices. As far as power I get 2.5 hours before needing to plug in. I'd expect to see about the same on the M4600. You might head over to your local big box electronic store. Dell seems to be well represented at most and hopefully they'd have a model with the IPS. I skipped the upgrade at the time and haven't felt the lack though if you like to work outside and it's bright enough it might be worth it. kashani

Re: [gentoo-user] Problem with xf86-video-ati nvidia-drivers
--snip-- The TV is an LG 47LH90 and and it is said to do 1080p. I looked for ghosting in 16:9 mode instead of Just Scan mode and strangely the shadows are there, but they're oriented top and bottom instead of left and right. I can take another photo if anyone would like to see. Why do I need to select Just Scan in order to prevent all 4 edges of the screen from being cut off? - Grant BTW I think you're on to something Stroller because the overall picture is definitely improved in 16:9 mode compared to Just Scan mode. I just need to figure out how to prevent the edges of the screen from being cut off. - Grant Grant, By default most TVs overscan inputs due to broadcast signals at the edges as the picture there is not well defined and can have white overscan lines and such. The TV compensates by overscanning which basically zooms in on the picture making (on my 46 Samsung TV) the outer 1-1.5 of the picture disappear. On my TV it was fairly simple to turn this off, I just had to label the HDMI input as DVI PC and it automatically turned off any picture processing/overscanning. Yours may be similar. Sorry if there's typos, I have a bandaged finger and it's a PITA to type with. I think I fixed all of them. Dan I found this: We recommend using the Just Scan mode with 1080i and 1080p material, which assures zero overscan and proper 1:1 pixel matching for this 1080p display. http://reviews.cnet.com/flat-panel-tvs/lg-47lh90/4505-6482_7-33485570.html# reviewPage1 Just Scan is what I've always used which has the ghosting problem. I think I'm back to square one. Just a thought: have you approached the OEM for the TV? If you could get to some technical department they would hopefully advise if this is a setting or hardware issue. That may be. I'll try that. Please let me know if you think this may be a software issue of some sort. - Grant

Fair enough.

Re: [gentoo-user] Re: Problem with xf86-video-ati nvidia-drivers
... I was thinking about this. The digital HDMI signal must be converted into an analog signal at some point if it's being represented as light on a TV screen. Electrical interference generated by the computer and traveling up the HDMI wire should have its chance to affect things (i.e. create weird shadows) at that point, right? Not with DFPs. Those work digital even internally. I assume of course that his HDMI TV *is* a DFP. But at some point the 1s and 0s must be converted to some sort of an analog signal if only right behind the diode. A diode must be presented with a signal in some sort of analog form in order to illuminate, right? no. If your tv is a standard flat panel, the sub pixels only go from on to off and back. Nothing else. There is no analog signal, no transformation nothing. And off means 'let light through' and on 'black' Every digital signal is encoded into an analog signal. I think it would take some serious EMI to sufficiently change the characteristics of an analog signal so as to create an error in the overlying digital signal if that signal is traveling along a wire. I can imagine it happens but I would think it's rare. Even if that signal were altered, I would think it just about impossible that anything but an error could be produced. Whether an LED is on or off is determined by whether or not it is forward biased. Biasing is established by analog voltages and/or currents, and those can be altered by EMI. Again, I would think it's very rare that EMI could affect an LED's forward biasing and change its state from on to off or off to on. However, what color an LED emits is determined by the energy gap of the semiconductor which is very much an analog process. How could it be anything else? How do you tell a photon to emit a certain color by feeding it 1's and 0's? There has to be at least one D/A conversion somewhere between the digital signal and the emittance of the LED, and that is the most likely point for EMI to affect the final output. If you have an led display it is pretty much the same. All the levels you see are achieved with fast switching. There are no analog levels. Stroller is probably correct with overscan/underscan. But that has nothing to do with digital/analog conversion. Digital is just a figment of our imagination after all. emm, no, seriously not. It is though. It only exists in the conceptual world, not the physical world. If you want to do anything with your digital signal besides change it, store it, or transfer it, there must be a D/A conversion. You're thinking of PCM. (And that's what I was thinking of, earlier, too). I assume Stroller and Volker are talking about PWM, where a perceived analog value is achieved by rapidly turning a signal from full-on to full-off. (Yes, there's no such thing as pure-digital in the physical world. The confusion here appears to be in PWM vs PCM.) -- :wq Everything I said above applies to both PCM and PWM. They are only conceptual layers built on top of a physical/analog base. PWM switching from full-on to full-off and back is an analog process representing digital data in order to represent an analog signal. - Grant

You can also create a swap file to supplement the swap partition if you don't want to or aren't able to repartition. I'd check the MySQL logs to see if it shows anything. Maybe check the settings with regard to memory upper limits (Google it, there's a lot of info about MySQL RAM management). If you're running any other servers that utilize MySQL like Apache or something, check its access logs to see if you had an abnormal number of connections. Bruteforce hacking or some kind of flooding/DOS attack might cause it to use more memory than it ordinarily would. A Basic what's using up my memory? technique is to log the output of top by using the -b command. Something like top -b toplog.txt. Then you can go back to the time when the OOM occurred and see what was using a lot of RAM at that time.

I don't think I've come across a display with a display port yet. Oddly VGA is the only common interface on all my display devices. Agreed. Macs have infested our techie areas, the things seem to breed under the desks overnight. Macs use DisplayPort and our techies can have their pick of just about any display device they feel like having (within reason). No-one has a native DisplayPort device, everyone has converter dongles (usual to VGA!) As far as power I get 2.5 hours before needing to plug in. I'd expect to see about the same on the M4600. This XPS M1530 gave me 2.5 hours when new with extended battery. A colleague with a one-year old Precision gets 4 on a standard battery! You might head over to your local big box electronic store. Dell seems to be well represented at most and hopefully they'd have a model with the IPS.

[gentoo-user] no_root_squash equivalent for virtualbox shared folders?
I've been trying to share /usr/portage on a gentoo host with a virtualbox gentoo guest, but I'm having an identity crisis ;) The /usr/portage/ share mounts perfectly on the gentoo guest, but even root (on the gentoo guest) can't write to the shared portage directory. After hours of googling and putzing around with mount options, I'm pretty sure that root on the host is not the same user as root on the virtualbox guest. This seems analogous to an NFS mount without the 'no_squash_root' mount option, but I haven't discovered the analogous solution for vboxfs mounts. Any applications of the cluestick would be most welcome :)

Re: [gentoo-user] mysqld invoked oom-killer
Does it sound like apache2 was using up all the memory? If so, should I look further for a catalyst or did this likely happen slowly? What can I do to prevent it from happening again? Should I switch apache2 from prefork to threads? Do you need the full 256 instances? How many simultaneous connections do you have? Are you running keep alive (connection persistence, and i *think* it also implies connection pipelining). Its the default these days but if you're been upgrading through older versions the config might have it disabled. Also, WRT swap you can set vm.swappiness in /etc/sysctl.conf from the default of 60 to something lower, to reduce the propensity to use swap.

Switching from prefork to threads and vice versa can be very difficult depending on which modules and libraries your site uses. It is not on the list of things you should try first. Or second. Maybe 37th. I wouldn't expect adding swap to do much in this case. Your site gets hit hard, Mysql is a bit slow, Apache processes start stacking up, the system starts swapping, disk is really slow compared to RAM, and everything grinds to a complete halt possibly locking the machine up. The easiest thing to try is to turn off keepalives so child processes aren't hanging around keeping connections up. Also lower the number of Apache children to 8 * number of processors or a minimum of 32. Test a bit. Turning off keep alive can cause problems for Flash based uploaders to your site and code that expect the connection to stay up. For most sites this shouldn't matter. Next I'd look at tuning your Mysql config. If you've never touched my.cnf, by default it's set to use 64MB IIRC. You may need to raise this to get better performance. key_buffer and innodb_buffer_pool_size are the only two I'd modify without knowing more. kashani

Re: [gentoo-user] mysqld invoked oom-killer
The easiest thing to try is to turn off keepalives so child processes aren't hanging around keeping connections up. KeepAliveTimeout defaults to 5 seconds, so that shouldn't be a significant problem, and you get the efficiency of persistence and probably pipelining too. Could be worth reducing some of the tcp timers (the *_WAIT ones) if your netstat is full of CLOSE_WAIT/TIME_WAIT etc sessions (which will be more of a problem if you turn off keepalives). But completely agree, if your mysql is sluggish, it will mean apache processes hang around for longer than they need to and therefore build up and use more memory. Use top then shift-m for quick overview of memory use.

So, given that I have three devices, /dev/sda, /dev/sdb and /dev/sdc, if I run the command mdadm --assemble --scan, would this find all the components and create a /dev/md0 disk without damaging the contents of the original RAID array? If you've got the space and time, a backup can't hurt. Using --scan will make it check the config file, but right now, there's probably nothing useful in it. This looks like what you want to do to me: If the --scan option is not given, then only devices and identities listed on the command line are considered. The first device will be the array device, and the remainder will be examined when looking for components. but I'd figure out where that md0 is coming from (below) first. When I tried mdadm --assemble --scan with nothing uncommented in the configuration file, I got mdadm: No arrays found in config file or automatically. Typing dmesg | grep md0 returned no lines. There are a couple of lines in dmesg when I run dmesg | grep md:, but they read md: linear personality registered for level -1 md: raid0 personality registered for level 0 md: raid1 personality registered for level 1 md: raid10 personality registered for level 10 md: raid6 personality registered for level 6 md: raid5 personality registered for level 5 md: raid4 personality registered for level 4 md: Waiting for all devices to be available before autodetect md: If you don't use raid, use raid=noautodetect md: Autodetecting RAID arrays md: Scanned 0 and added 0 devices md: autorun... md: ... autorun DONE. I think this means that raid5 is set up correctly in the kernel, but it can't find the raid array. Next I tried adding a line to the config file: DEVICE /dev/sda /dev/sdb /dev/sdc mdadm --assemble --scan returned the same results as before Next, I tried commenting out the previously added DEVICE line, and adding ARRAY /dev/md0 devices=/dev/sda,/dev/sdb,/dev/sdc mdadm --assemble --scan returns something different mdadm: /dev/sdb has no superblock - assembly aborted. The only item in /dev/mapper is th default 'control' entry. There is a /dev/md0 item already listed, but presently when I try to mount it, it reports that it is unable to read the superblock. Would the command above fix this? Depends. Where'd the md0 come from? You probably have something in your logs or dmesg, unless that device was created manually on your old system. Where is the config file mentioned in your e-mail, and do I need to edit it first to add the three raid disks? It's /etc/mdadm.conf. You don't need it to create or use the array, but you'll want to run mdadm when the machine boots and the config file tells it what to do. Once the array is working, you can just do, mdadm --detail --scan /etc/mdadm.conf mdadm --detail --scan returns no output. Also, I just checked /dev and md0 is now gone from the list. Since there are also /dev/sg0, /dev/sg1 and /dev/sg1, I also tried those instead of /dev/sda, /dev/sdb and /dev/sdc in the ARRAY line, but mdadm --assemble --scan returned no output I tried re-booting, but /dev/md0 is now permanently gone.

[gentoo-user] New computer and Gentoo
Hi everyone, Today, I ordered a new desktop from Dell (offer too good to pass up!). The system is a Dell XPS 8300 with an Intel Core i7 processor. I was reading the Gentoo wiki about safe CFLAGS and it said that march=native is recommended if I use gcc = 4.2.3. I looked at processor specific CFLAGS and if I am understanding this correctly, for an Intel i7, I would use march=prescott for a 32 bit OS. It also mentions march=core2 if using gcc 4.3 for a 64-bit OS. However, it has amd64 in brackets. So would this be for an amd system? Should I stick with march=native? Advice would be appreciated. Regards, Colleen -- Registered Linux User #411143 with the Linux Counter, http://counter.li.org
Re: [gentoo-user] New computer and Gentoo
amd64 means any x86 64bit platform, so Intel too. march=native is good if you're not using distcc, or if you're only using distcc on core2 boxes. Otherwise be specific.
