IEGD to xf86-video-intel

[Dragoș Carp <dragoscarp@xxxxxxxxx>]

Hi all,

I'm trying to update an old linux board Advantech PCM-9361 (Intel Atom N270+ 945GSE+ ICH7M) Linux 2.6.32 + IEGD to the newest opensuse 13.1: Linux 3.11.6 + xf86-video-intel 2.99.906.

The IEGD driver has some settings (Port Attributes) that cannot be set in xf86-video-intel.

Is it possible to set them with the intel_reg_write utility? Are there any reference documents describing the IEGD Port attributes?

Below is the xorg.conf with the iegd settings. The interesting lines are "Attr/26" "18" for ports 2 and 4: the TFT panels are 18bbp color depth (the panels don't provide any EDID info).

With the new configuration the colors on LVDS2 panel are wrong (probably set to 24bbp) and LVDS1 panel is black although xrandr shows it as active.

Any ideas?

Regards,

Dragos Carp
