Hi
I'm struggling with a custom-made carrier board for Congatec QA6 Qseven module running Atom E660T and Intel EG20 chipset, more info here: http://www.congatec.com/qa6.html.
18-bit 5.7" LVDS panel is connected directly to the module data lines and I'm encountering interesting problems with grub and tty output. Resolution should be panel's native 640x480, but I have five top lines duplicated at the bottom of the screen. Could this be something about Ubuntu trying to run 24-bit data on 18-bit display (the fourth data signal pair is not connected) or just about resolution?
Also, Natty's GRUB entry with line "set gfxpayload=$linux_gfx_mode" got me to blank boot screen and ttys, but fixed it with "GRUB_GFXPAYLOAD_LINUX=text" in /etc/default/grub.
Any help appreciated, I've been banging my head on keyboard and don't know where to start.
Edit: Let me point out that carrier board only routes signals to external connectors and provides power, thus EG20 drivers are all that's needed. BIOS screen is ok without those duplicate lines, so this problem exists only in Linux.
Second edit: It was BIOS after all, needed some tricky cfg
