Can't change screen resolution [Solved]

hosage · 2011-01-13 20:19:29

Hello, for some reason, when a bunch of strange problems showed up, the default screen resolution changed to 640x480 and i can't change it by using the GUI or xrandr -s <resolution> (it says that the requested resolution is not in the modes, even when it actually is in xorg.conf).

xrandr output (whitout mouse and keyboard sections):

Screen 0: minimum 320 x 200, current 640 x 480, maximum 8192 x 8192
LVDS1 connected 640x480+0+0 (normal left inverted right x axis y axis) 303mm x 190mm
640x480 59.9*
VGA1 disconnected (normal left inverted right x axis y axis)
DVI1 disconnected (normal left inverted right x axis y axis)
TV1 disconnected (normal left inverted right x axis y axis)

xorg.conf (whitout mouse and keyboard sections):

The card is an integrated Intel GM965 on a Dell Inspiron 1525
It worked perfect untill the second coming of strange problems that, just as the first time, were solved by some update or something, except for the screen resolution

Any idea?

That doesn't look like a very good xorg.conf...
in the device section you name the device as "Intel GM965" then in the screen section you call the device just "GM965".
I would rename the xorg.conf something else and let X figure things out.
You could also read /var/log/Xorg.0.log to find out what's going on.

Have you checked in /etc/X11/xorg.conf.d ? might be worth reading Arch wiki on Xorg for more information

Can you make up your mind? ;-)

Run

pacman -Qs ^xf86-video

and post the output.
Post the relevant part of /var/log/pacman.log - the upgrade that broke the resolution.

sorry for the wrong tags... long story.

About the nvidia thing, it kind of surprised me since i don't remember messing with nvidia drivers but maybe, following a wrong guide i actually did, but i'm sure it is a intel GM965

pacman -Qs ^xf86-video:

local/xf86-video-fbdev 0.4.2-2 (xorg-video-drivers)
    X.org framebuffer video driver
local/xf86-video-intel 2.13.0-4 (xorg-video-drivers)
    X.org Intel i810/i830/i915/945G/G965+ video drivers
local/xf86-video-vesa 2.3.0-3 (xorg xorg-video-drivers)
    X.org vesa video driver

Sometimes after an upgrade happens that video modules won't detect correctly your video card -usually the built-in motherboard videocard- and/or the chip that identifies your monitor anymore.
I remember having this kind of issues from time to time when running Debian-based OSs AND Via OpenChrome modules for the ViaChrome chipset with a 17" CRT LG StudioWorks monitor.
I'm sorry I can't help you anymore but I hope I had help you head the right way to research and resolv your problem.
Best!

I don't know how did you create that xorg.xonf, but do as moetunes suggests and remove / rename it so that X can work things out by itself. I'm not using xorg.conf anymore and never had any problems.

Please post /var/log/Xorg.0.log and the relevant part of /var/log/pacman.log.
If you haven't updated in a long time, maybe your problems are related to http://mailman.archlinux.org/pipermail/ … 18235.html

Solved!
The problem was in the xorg.conf file like everyone said, not sure how i end up with that file, or how got nvidia got involved, but i copied the conf file of https://wiki.archlinux.org/index.php/De … 1525#Video and it worked perfect (at the second reboot, the first time the keyboard lights freaked out).

Thanks a lot everyone.

I don't see an xorg.conf file in that link.

Really, as has been said, I also think you'll be better off without an xorg.conf. Xorg is very good at setting everything up itself (on Intel graphics at least). If you use an xorg.conf, you'll probably just give yourself problems.

hosage · 2011-01-14 19:05:28

It was changed yesterday.
So you think i just should rename/delete xorg.conf and forget about it?

Rename it and give it a shot. You can always put it back if you liked it better with the xorg.conf. I've been xorg.conf-less for a couple years now and see no reason to use it anymore.
