Hi Jani,

thank you for your response.
Attached is the dmesg output trimmed of more thousand lines like: 
[drm:i915_irq_handler], pipe B underrun

Kernel command line was:
linux   /boot/vmlinuz-3.11.6-4-desktop 
root=UUID=12529369-6b58-4afe-8e65-9801c19ad8c5 
resume=/dev/disk/by-id/ata-SQF-P10S2-4G_7DF707151A0900716999-part1 
splash=silent drm_kms_helper.edid_firmware=edid/1920x1080.bin quiet 
showopts drm.debug=0xe video=VGA-1:d video=LVDS-1:1920x1080 
video=LVDS-2:1920x1080

Result was the same: LVDS-2 starts with right resolution, but wrong 
colors and LVDS-1 stays black.

I know that the panels are right connected, because the IEGD driver 
starts both panels, but without direct rendering :(.


Thanks,
Dragos
