screen set to 640x480 after update

Hey all. I have an nvidia 8800GT graphics card and am running an updated arch linux system using the "nvidia" driver. It was working fine until I did an update a while ago (probably a few weeks ago) and then after the reboot, my screen was set to 640x480 and in KDE4, I was unable to set it any higher. Does anyone know why this is happening?

Re: screen set to 640x480 after update

No idea, buddy. Anywho, have you tried setting your resolution using:

xrandr -s resolution goes here

or in /etc/X11/xorg.conf?

Section "Monitor"
    Option    "PreferredMode"    "resolution goes here"
EndSection

Thanks for the reply. Neither worked.

Same problem with Nvidia 6600GT... 800x600 by default and can't change it...

[saneone@mordor ~]$ xrandr -s 1280x1024
Size 1280x1024 not found in available modes

Nvidia has the 185 drivers out. Maybe you could try those. I haven't tried them yet.

Re: screen set to 640x480 after update

I had the same problem with a nvidia GeForce 9500 GT. It seems that X is not able to read information from the display anymore. Form xorg.log:
"(WW) NVIDIA(GPU-0): Unable to read EDID for display device CRT-0".
It then falls down to the settings in xorg.conf. I had to set:

HorizSync       31.5 - 90.0
VertRefresh     60.0 - 75.0

in xorg.conf to be able to use the higher resolutions.

Thanks for the reply. I tried that. It still doesn't work. Here's my xorg.conf:

Re: screen set to 640x480 after update

You can backup your xorg.conf and try various schemes like 'hwd', 'nvidia-xconfig', 'nvidia-settings' and whatever you can. If you f.e. need xinerama, make sure KDE is compiled w/ it, you can try qtmod, qt and gnome to see if it helps.
Everything up to date? Anything interesting in the logs?

Nothing I do is making this work. I'm going to try the vesa drivers next and see if that helps. If not, I'll see if an Ubuntu live CD will work. If it doesn't, then there may be something wrong with the hardware. It's dual booting on windows and windows is working fine, though.

Good idea. If you can get a LiveCD to work, you can poke around in its configs and see what made it work.

It's odd. I used unetbootin to create an Ubuntu live USB stick. It had always worked. Now when I booted into the USB stick, I was dropped to the initramfs shell. I then tested the stick on my laptop. Worked perfectly...

Windows still works though.
