[SOLVED] Setting higher reslution using the nouveau driver

kcholakov · 2012-05-11 21:05:56

Hi all,

I just upgraded my system and installed the nouveau driver (as described here https://wiki.archlinux.org/index.php/Nouveau), because the nvidia driver seems to be incompatible with newer xorg server (http://www.archlinux.org/news/nvidia-17 … rom-extra/) , right ?

So now it seems that I am running the X with the nouveau driver, but the resolution of my monitor is 1024x768. This is not very cool because it was 1280x1024 before the upgrade. I am using KDE and its screen & resolution tool does not show something higher than 1024x768 too.

Can you give me some help setting back the correct resolution or give me some link to similar discussion when I can find the info?

Thanks a lot!

Did you reboot after the drivers switch? https://wiki.archlinux.org/index.php/Ge … y_projects might help.
If it doesn't, post your xorg log.

Nouveau has a bug currently. It'll be fixed in the 3.4 kernel.

I'm using nouveau and everything's fine.

I'm lazy, can you share a link to said bug?
Are you talking about https://bbs.archlinux.org/viewtopic.php?id=140961 ?

Yep, that's what I mean. And that's not the only thread with nouveau resolution problems.

"Invalid EDID checksum" is not actually the error, I've had that since forever on my old laptop, but neither nouveau nor nvidia mind. The problem is elsewhere, and the fix will be in kernel 3.4 (and then maybe ported back to 3.3).

I don't know if the lts kernel has the bug. kcholakov, can you test linux-lts?

kcholakov · 2012-05-12 05:44:44

Nope, linux-lts did not solve the problem (just installed it). But just to be sure I am not doing anything wrong...when installing the nuveau driver do I need to change anything manually in xorg.conf or other file under /etc/X11?
Because what i did is just doint this:

# pacman -Rdds nvidia nvidia-utils
# pacman -S --asdeps libgl

as described in the Wiki.

Looking at my xorg.conf I see:

Section "Device"
Identifier "Card0"
Driver "nouveau"
BusID "PCI:1:0:0"
EndSection

Section "Device"
Identifier "Card1"
Driver "vesa"
BusID "PCI:1:0:0"
EndSection

So it seems the file was updated I am running nouveau, but do I need to change anything else manually?

Hi again,

I just installed 'xf86-video-nv' instead of 'nouveau' and everything works like a charm. I have 3d acceleration too.

Thanks for all you replies to this thread :-)

Gcool · 2012-05-12 06:03:01

Good to hear you managed to solve it.

Don't forget to mark your thread as [SOLVED].

Gusar · 2012-05-12 08:47:41

Err, with nv you definitely do *not* have 3D, not hardware accelerated. nv does basic userspace modesetting (no multi-monitor) for older cards, and that's it. Ok, there's also Xv.

I wouldn't call using nv a "solution", when a fixed nouveau gives you KMS, 2D acceleration with EXA, and actual 3D acceleration.

kcholakov · 2012-05-12 11:53:20

You are right, I do not have 3d acceleration. I got confused by something else.

I'll give a try to nouveau again when kernel 3.4 comes up.
