Custom Resolution In X?

tux-junkie · 01-06-2005, 03:11 PM

I just installed Debian (Sarge) on my laptop, and everything works great. But, I have a widescreen display, and I wanted to know if it was possible to specify a custom resolution for said display -- something like 1280x800. Thanks!

Edit the "modes" in your /etc/X11/xorg.conf file...

Section "Screen"
Identifier "Screen 1"
Device "NVIDIA GeForce"
Monitor "My Monitor"
DefaultDepth 24

Subsection "Display"
Depth 8
Modes "800x600" <--- EDIT
ViewPort 0 0
EndSubsection

Ah, thanks! I knew there was a file like that somewhere, just didn't know where.

Well, I don't have that file. Could it be anywhere else/named something else?

check for a XF86Config file. i just put FC3 on my gfs laptop (dell 700m) and I couldn not get 1280x800 to work. even if it was the only resolution in my xorg file. it would always defualt to 1024x768. trying to change the resolution in gnome didn't even give me the 1280 choice.

find a program called 855resolution. Compile and put it in /usr/sbin. Then on boot (in the rc.local file) put the following line:
/usr/sbin/855resolution 38 1280 800

That inserts a mode 38h of 1280x800 whcih will then let X find and bring it up.

Good Luck!
