[SOLVED] Resolution only 800x600 fedora 12 intel 82G33/G31

[wnorth]

The max resolution I am allowed is 800x600. This seems to be coming from a probe of the Intel 82G33/G31. My xorg.conf is set for the Qptiquest Q9 correctly.

I was using Fedora 10 with this same system and got the 1024x768 that I wanted but when I went to fedora 11 I only got 800x600. After installing fedora 12 the same.
But a couple weeks ago, after a reboot I suddenly got 1024x768 again and thru assorted reboots it stayed. Until today. After a reboot, now only 800x600.

Is my integrated 82G33/G31 maybe going flakey on me?
Or is there something I'm missing.

thanks!

Hi and Welcome !

Which Graphics driver are you using? Post the contents of /etc/X11/xorg.conf file here.

--- same driver as when it worked earlier.

First of all, set correct HorizSync and VertRefresh rates. Check your Monitor's Manual.
These are Generic Refresh rates and work fine for most of displays :

HorizSync 30.0 - 71.0
VertRefresh 50.0 - 160.0

In case it doesn't work, try "vesa" driver instead of "intel".

[wnorth]

The sync rates I had were from the monitor manual so they were good,

Ah! It was the change of driver from intel to vesa that fixed it.

Thanks to devils casper.

Interesting is that it had been intel since way back.
O well, now you see it now you dont.
