[Bug 554569] Re: [lucid] Blank screen with KMS on Thinkpad X201 with Arrandale (i915)

[Mubes]

Datapoint; With latest X201 BIOS (BIOS: 1.14 / ECP: 1.08/1.08) from
lenovo I can get i915 driver working on the external display by removing
the modeset and vesa elements from the kernel command line. I also get
full effects etc. and i915 is in use according to lsmod. This is using
'stock' 64 bit 2.6.32-22 generic kernel.  I cannot get any display on
the LCD panel at all, although It will wake up the backlight if I try to
switch on both screens.

This new BIOS has improved a few items - I understand that the ACPI is
now more stable and certainly the display on the external (4x3) monitor
'fits' a lot better than it did before.

Not sure it's much use, but just in case....
