[SOLVED] xorg.conf problems

I just ran pacman -Syu on the desktop and installed some software to get my digital camera working (gtkam and all of its dependencies and the stuff listed on the archwiki article), and when I reboot my xorg.conf no longer worked. My monitor gave me an "out of range" error.

The tried re-running nvidia-xconfig, but no difference. The best I could figure out to do was comment out horizontal and vertical refresh. Now X starts up ok, but the resolution is tiny. Can anyone help me out?

xorg.conf

Re: [SOLVED] xorg.conf problems

If you can run X, post the output of 'xrandr'.
Have you tried running w/o the xorg.conf or adding a modeline with the resolution you want to your xorg.conf?

Re: [SOLVED] xorg.conf problems

You don't need an xorg.conf anymore, so try without one. If it doesn't work, post /var/log/Xorg.0.log. Also, what kind of display is it and which resolution do you want?

xrandr

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 320 x 240, current 640 x 480, maximum 640 x 480
default connected 640x480+0+0 0mm x 0mm
   640x480        50.0*
   320x240        51.0

Xorg.0.log

Starting without xorg.conf doesn't have any effect. Still displays at 640x480. I'm not sure about the display. It's some cheap monitor I skimped out on years ago. I was never able to find any documentation on it on the Internet. I'd like to to run in 1024x768. The label on the back says A170E1-TOM Rev. C1.

[    24.336] (WW) NVIDIA(GPU-0): The EDID read for display device CRT-0 is invalid:
[    24.336] (WW) NVIDIA(GPU-0):     unrecognized EDID Header.

[    24.352] (WW) NVIDIA(0): Unable to get display device CRT-0's EDID; cannot compute DPI

That's our problem.

What's the output of 'xrandr --prop'?

Re: [SOLVED] xorg.conf problems

Woah woah, hold on. A reboot without xorg.conf seems to have solved the problem, sorry. Thanks for the help!
