Re: [Libreboot] lcd-panel 1440x900 not working (external monitor ok)

[Marcel Maci]

Hi Leah
Thx for your quick answer. I actually tried 
libreboot_experimental-84-g2f2e2ee_grub_t400_8mbcd image 
t400_8mb_usqwerty_txtmode.rom today. I had inserted MAC-Adress with ich9gen and 
then flashed it directly on the Thinkpad (with flashrom utility from stable 
release). I used txtmode because I thought that this way I could at least get 
GRUB. Dont know, what went wrong (maybe I should have flashed it externally 
again or used ./flash update instead of flashrom?), but after the flash, the 
computer didn't boot any more. So I flashed the 20150518 image again with 
Raspberry Pi.
If you think that there is a chance that it works with the vesa image (instead 
of txtmode), I can try that (in the next days or so)
Thx a lot for your work: libreboot is genious (I already use it on a Thinkpad 
x60s and it works great!!)
Marcel
