| * ara hugs RAOF for working on bug 824099 :) | 07:27 | |
| RAOF | It's not so much a fix as a "please don't do that, use Unity 2D if you want to span your displays". :/ | 07:28 |
|---|---|---|
| alkisg | Hi, I've a lab of computers where the graphics card uses the pm2fb.ko module. The videoram is 4 MB, but only 512 KB are detected. | 07:47 |
| alkisg | I tried forcing VideoRam in xorg.conf, but it made no difference | 07:48 |
| alkisg | Would trying a newer kernel help? What else can I try? | 07:48 |
| RAOF | alkisg: Is that permidia? | 07:57 |
| RAOF | Old school! | 07:57 |
| alkisg | RAOF: yes, and yes | 07:57 |
| alkisg | Too old, but unfortunately that school can't afford the change | 07:57 |
| alkisg | I'm trying to install the backported natty kernel (using lucid) | 07:58 |
| RAOF | xorg.conf isn't going to have any effect; that's a kernel framebuffer driver - there is no X driver involved. | 07:58 |
| alkisg | If anyone has some other ideas I could try... | 07:58 |
| alkisg | Ah | 07:58 |
| RAOF | Or, rather, there's an X driver involved, but it's just a dumb FB driver. | 07:58 |
| alkisg | Isn't there any way to force X to use a particular mode even though it thinks there's not enough videoram for it? | 07:58 |
| RAOF | No. X isn't setting the mode at all. | 07:59 |
| alkisg | (the school had windows previously, cards worked fine there) | 07:59 |
| jcristau | you can try playing with fbset | 07:59 |
| ara | RAOF, good to me. Right now it is: do what you want but your display will look awful | 07:59 |
| jcristau | or hacking up your kernel driver | 07:59 |
| RAOF | You *might* be able to pass some kernel module parameters to that module. | 07:59 |
| RAOF | alkisg: parm: mode_option:Initial video mode e.g. '648x480-8@60' (charp) | 08:00 |
| alkisg | I tried `modinfo pm2fb` but I didn't see any options... ah that one | 08:00 |
| alkisg | Let's see if it can use it even though it thinks it doesn't have enough ram | 08:00 |
| RAOF | ara: Yeah. Or, in my case, be software rendered on the *super fast* atom processor, for a blazing 30 seconds per frame performance. | 08:01 |
| RAOF | Let's see if this works... | 08:02 |
| alkisg | jcristau: I tried `fbset` and it says "cannot open /dev/fb0" | 08:05 |
| alkisg | trying to pass mode_option in the command line... | 08:06 |
| jcristau | err | 08:08 |
| jcristau | if you're using pm2fb.ko surely you have a fb device... | 08:08 |
| alkisg | I'm using LTSP, and that's a thin client, but I don't think ltsp would interfere with that... :( | 08:09 |
| alkisg | Is this a correct syntax? initrd.img ... mode_option:1024x768-16@60 | 08:12 |
| jcristau | no | 08:14 |
| alkisg | Here are some files from the client: http://paste.ubuntu.com/697123/ | 08:18 |
| alkisg | xorg.log, cmdline, modinfo etc | 08:18 |
| alkisg | ls -l /dev/fb* says file not found | 08:19 |
| jcristau | well pm2fb is not loaded | 08:21 |
| jcristau | so clearly you're not using that | 08:21 |
| alkisg | I'm reporting what `lspci -nn -k | grep -A 2 VGA` told me: Kernel modules: pm2fb | 08:22 |
| jcristau | yes, that means pm2fb could drive that hw | 08:23 |
| jcristau | otherwise it would tell you Kernel driver in use: $something | 08:23 |
| alkisg | Ah. modprobe pm2fb indeed loaded the module now | 08:24 |
| alkisg | And I have an /dev/fb0 now | 08:24 |
| alkisg | jcristau: a big improvement, thanks. After manually loading pm2fb, I got X at 640x480 | 08:31 |
| alkisg | Any advice on how to force that to 1024x768? | 08:32 |
| alkisg | Will running `fbset params` before loading X help? | 08:32 |
| jcristau | i don't know. | 08:32 |
| alkisg | Thank you though. Could you help me for the correct syntax on the mode_option parameter? | 08:33 |
| alkisg | (11:12:41 πμ) alkisg: Is this a correct syntax? initrd.img ... mode_option:1024x768-16@60 | 08:33 |
| alkisg | (11:14:33 πμ) jcristau: no | 08:33 |
| alkisg | *could someone help me... | 08:33 |
| tjaalton | http://www.linuxdoc.org/HOWTO/Framebuffer-HOWTO/x168.html | 08:38 |
| tjaalton | see the part about permedia | 08:38 |
| * alkisg reads, ty... | 08:45 | |
| alkisg | Phew that was a difficult one to do via VNC! After all the troubleshooting, I solved the problem by putting the following in my LTSP lts.conf configuration file: | 09:54 |
| alkisg | MODULE_01="pm2fb mode_option=1024x768-16@75" | 09:54 |
| alkisg | Thank you all for your help, yet another school just moved to Ubuntu/LTSP. :) | 09:54 |
| mdeslaur | Hi X hackers...any known workaround for bug 858450 ? | 12:27 |
| tjaalton | bug 858450 | 12:28 |
| tjaalton | huh, no bot | 12:29 |
| * mdeslaur is saddened by bot's suicide | 12:32 | |
| tjaalton | mdeslaur: uh, I understand how annoying the bug is.. | 12:36 |
| tjaalton | as a quick test I can only suggest trying a 3.1rc mainline kernel | 12:36 |
| mdeslaur | tjaalton: do we have a mainline ppa somewhere? | 12:37 |
| tjaalton | mdeslaur: yes http://kernel.ubuntu.com/~kernel-ppa/mainline/ | 12:39 |
| mdeslaur | tjaalton: ah, thanks! | 12:39 |
| tjaalton | mdeslaur: i don't have working ati-gear here, so haven't seen bugs like that myself. maybe others on this channel have though | 12:54 |
| mdeslaur | tjaalton: thanks | 13:01 |
| kamstrup | I almost assume that it's a known issue, but I can't find it in LP: my integrated intel graphics hd 3000 (sandybridge) no longer works (no glx). This worked smoothly ~1 month ago... ? | 13:27 |
| kamstrup | I am not 100% sure where the regression happened because I normally use the discrete nvidia card on my laptop, but decided in a fit of adventurousness that I wanted to try the integrated intel again yesterday... | 13:28 |
| kamstrup | (so just to make it clear optimus is disabled in the bios, so it's not running hybrid, just pure old intel graphics hd 3000) | 13:29 |
| Sarvatt | you have to remove the nvidia driver | 13:30 |
| tjaalton | right | 13:31 |
| kamstrup | ah, ok | 13:34 |
| kamstrup | thanks Sarvatt, tjaalton that helped :-) | 13:39 |
| Sarvatt | kamstrup: you can do it without removing it if you plan on doing it a lot also | 13:45 |
| Sarvatt | sudo update-alternatives --config gl_conf (pick mesa instead of nvidia) | 13:46 |
| Sarvatt | sudo ldconfig | 13:46 |
| Sarvatt | sudo update-initramfs -u | 13:46 |
| kamstrup | Sarvatt: yeah, it might be helpful for testing out Unity performance | 13:46 |
| Sarvatt | (then reboot) | 13:46 |
| * kamstrup stores a note | 13:46 | |
| Sarvatt | same thing picking nvidia again to go back | 13:47 |
| tseliot | kamstrup: if you're using oneiric you might want to replace "gl_conf" with either "x86_64-linux-gnu_gl_conf" (on Ubuntu 64bit) or "i386-linux-gnu_gl_conf" (on 32bit) | 13:49 |
| kamstrup | tseliot: ah, that's also way easier mnemotechnically ;-) | 13:49 |
| tseliot | kamstrup: I'm on Ubuntu 64bit and simply type update-alternatives --configure x86 and then I press TAB for autocompletion since I can't remember the whole string | 13:50 |
| kamstrup | Long live tab completion :-) | 13:51 |
| tseliot | :) | 13:51 |
| alkisg | Yeah I started using it on norm<tab> senten<tab> too. Unfor<tab> it doesn't work :( | 13:52 |
| kamstrup | yeah, i kn | 13:58 |
| bjsnider | since when does optimus work on linux? | 14:32 |
| kamstrup | bjsnider: it "works" if you disable it in the bios ;-) | 14:32 |
| bjsnider | no, you said you normally use the nvidia chip exclusively | 14:33 |
| tjaalton | ironhide works somewhat | 14:33 |
| kamstrup | bjsnider: exactly | 14:33 |
| kamstrup | bjsnider: disable optimus, using only the discrete card | 14:34 |
| bjsnider | i see | 14:34 |
| bjsnider | you're lucky your craptop gives you that option | 14:34 |
| bjsnider | a lot of them don't let the user have that much control over the graphics setup | 14:34 |
| kamstrup | bjsnider: wow, I'd actually expect one to be able to deactivate the hybrid mode in the bios, and at least use the integrated card in a dedicated way | 14:43 |
| kamstrup | even on cheap hardware | 14:43 |
| kamstrup | ignorance is bliss | 14:44 |
| bjsnider | i've talked to people recently who say they've been through the bios and there is no such option | 14:45 |
| bjsnider | i would think that would make it very hard to buy a laptop if you intend to put linux on it | 14:50 |
| shadeslayer | hey, anyone have a idea how to get my intel i915 kernel module working? I get : *ERROR* drm/i915 can't work without intel_agp module! | 17:48 |
| shadeslayer | i have a seprate discrete graphics card, but i'd like to power that down and just boot using the intel agp | 17:48 |
| ricotz | Sarvatt, hi, are you ok with if i just copy the cairo packages with its current version string to edgers? | 19:51 |
| Sarvatt | ricotz: yup! | 20:10 |
| ricotz | Sarvatt, done ;) | 20:12 |
