DVI /S Video issues in linaro-m-netbook-efl-tar-20101024-0.tar.gz with Beagle Board XM Rev A3
Dear All,
Looks like something is broken in the new kernel ( Post changes to the bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/663642 ), In the earlier versions of the kernel atleast the S- Video used to work ( tested in Maveric 2.6.35.6-l5 Regular/Non netbook edition ).
Now If I pass omapfb.mode=tv:pal omapfb.default_disp=tv .. the xorg exits with with /dev/fb0 no such file or directory ( and ls -l on /dev/fb* confirms there is no files by that name ), I tried omapfb.mode=lcd:640x480 ( and other resolutions ), the X server starts but No out put on the screen / LCD tv thorugh S Video.
The DVI port with default options ( and tried with different resolutions as well ) connected through HDMI cable to the TV No output on the display in any Distributions/OS/Kernel I have tried sofar.
I understand that Fixing DVI might take some time because there is a HW change in Beagel Board XM A3, However I I would really appreciate if some one point me how to get atleast S Video output till HDMI starts working again.
Thanks

If I remember correctly omap boards use /dev/omapfb And it's configured in /etc/X11/xorg.conf in the filesystem should have Driver "fbdev" See http://elinux.org/BeagleBoardDebian#Xorg_omapfb_Drivers

thanks for the reply, Will try that later today However FYI ... If I choose anything else other than omapfb.mode=tv ( For eg dvi or lcd ), /dev/fb0 , /dev/fb1 will come back, They disappear only when I use omapfb.mode=tv, Not sure it really matters but thought should let you know.
