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