Output of demidecode

The Driver doesn't seem to recognize any more the laptopscreen since 3.10. In 3.9 everything worked fine.
My Laptop is a TX300CA.
Attached is the output of dmidecode.

If I login over ssh and try to start the X-Server I get following ERROR:

xf86OpenConsole: VT_ACTIVATE failed: No such device or address

Can you please attach the complet Xorg.log and also please boot with drm.debug=0xe and then grab the complete dmesg and attach it, too.

Asus TX300 variant, ivy bridge, efi boot, broken at 3.10, clamping bpp for eDP panel to BIOS-provided 18 -> very likely dupe of bug 59841.

Either try CSM/legacy boot or the patch in bug 59841 on top of drm-intel-nightly.
Comment 6 Jani Nikula 2013-10-21 08:25:33 UTC 
The patch being attachment 111321 [details] "drm/i915/dp: workaround BIOS eDP bpp clamping issue".
Comment 7 mealejan 2013-10-22 16:19:26 UTC 
Trying the CSM/legacy worked for me. I will try the patch the next few days.
Comment 8 Jani Nikula 2013-11-11 12:44:36 UTC 
Presumed dupe of bug 59841 which is fixed by 
commit c6cd2ee2d59111a07cd9199564c9bdcb2d11e5cf
