Hi,

I installed gnome and added Driver "fbdev" to xorg.conf. How do I change the screen resolution. It is at only 800x640.

= Setting Video Resolution = It first depends on what kernel version you are using.

You have to define it at boot time, thru u-boot, this would set 1280x720x16 for 2.6.29. setenv bootargs 'console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro omapfb.mode=dvi:1280x720MR-16@60' saveenv

For 2.6.27/2.6.27: video=omapfb:mode:1280x720@60

For 2.6.28: omap-dss.def_disp=lcd omapfb.video_mode=1280x720MR-16@60

For 2.6.29: omapfb.mode=dvi:1280x720MR-16@60

Common Modes: (not every combination is supported) 800x600MR-16@60, 1280x720MR-16@60, etc... Main doc is here: http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap-2.6.git;a=blob;f=Documentation/fb/modedb.txt;h=ec4dee75a35450376ad13442ea926eaf76de76aa;hb=HEAD
