[Bug 601376] Re: 2.6.35-6.9 (and newer) kernels having issues with invalid EDID info and ATI Radeon graphics

[baben]

It seems to be the same problem here.

Kernel: 2.6.35-22
Dell Latitude E6410 ATG
Graphics card: Mobile Intel Integrated Graphics Media Accelerator X4500HD

after grub I get a blank screen on every boot. 
when I plug in an external monitor I get a signal only at the external screen. 
if I unplug the external monitor I get a blank screen. 
if I then plug in the external monitor again I get a signal on both screens. 

I've tried:
Samsung SyncMaster LD190
DELL TFT Monitor 2209WA

same issue.
