Video modes on Debian

Post by archinet »

I have installed latest Debian on fitPc2. The major problem is that maximum resolution that I am able to get is 640x480. On this machine and same screen LG 30inch previously was installed XP, which gave me decent 1280x768. What should I do?

Good Day

The FitPC2 uses an Intel GMA500 graphics acceleration. You should to insure that Debian uses the appropriate driver for this GA to be able to get higher resolutions

I've got the same problem at beginning. I solved it in this way:

Code: Select all

`--# cat /etc/modprobe.d/uvesafb.conf 
options uvesafb mode_option=1280x1024-16 mtrr=3 scroll=ywrap
.-(/etc)---------------------------------------------------------(root@fitpc2i)-
`--# cat /etc/grub.d/01_915resolution 
echo insmod 915resolution
echo 915resolution 49 1280 1024 16
My screen has a physical resolution of 1280x1024. Just use google to find the correct 915resolution-line for your 1280x768 and generate a file in /etc/grub.d like above. After this just do a "update-grub" at command-line.
After reboot, you can try "modprobe uvesafb mode_option=1280x768-16 mtrr=3 scroll=ywrap" on command line.
