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

Upgrade_X-loader_and_U-boot
Hi Rob,
I just added some hints and discussion on Upgrade_X-loader_and_U-boot
Since this is related to the content found at git://github.com/RobertCNelson/flash-omap.git
I thought you are surely directly involved there. Thanks.

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...

the "I don't know" method of finding your SD card
Here is me attempting to use your method for finding your SD card on my Maverick Meerkat Ubuntu machine:
administrator@ubuntu:~/desk$ sudo ./setup_sdcard.sh --mmc /dev/idontknow [sudo] password for administrator: sudo: ./setup_sdcard.sh: command not found administrator@ubuntu:~/desk$
Not
Are you sure? I Don't see [/dev/idontknow], here is what I do see..
as you said would happen. What OS/version do you run in which this works?
Anyways df -h, (while provoking an admittedly less charming response from the computer!), works for me. Why did you change the page to use this new method? I strongly suspect that using df -h to list the amount of free space on each disk (and hence where they each are) would have a more universal result on more types of Linux machines than using sudo ./setup_sdcard.sh --mmc /dev/idontknow. Would you mind if I reverted it back to the method I had originally put?
