Created attachment 36332 [details] lspci -vv If I disable KMS with the nomodeset kernel option the screen works fine, but X will not not work with the intel driver (no kernelmodesetting driver detected). If I boot without the kernel option the screen blanks as soon as kms loads. I tried kernels with the modules compiled in, putting the modules into the initramfs, and just loading them late. I got the same results just at a different point in boot process. The Hardware is a HP 8440p Laptop with Core Processor Integrated Graphics Controller and display port. The VGA out doesnt have any output as well, but I could not test the display port yet. I am using Archlinux with stock kernel 2.6.34-ARCH. I did try the xf86-video-intel drivers from the git repository and the linux2.6.35-rc3 kernel with the same results. Any help would be appreciated. Regards, Tobias

looks similar to bug#28224?
Looks like the same eDP issue. Could you attach "intel_reg_dumper" output in 'nomodeset' case and in kernel failure case?
Created attachment 36355 [details] output of intel_reg_dumper with kms disabled
Created attachment 36356 [details] output of intel_reg_dumper with kms enabled
Please test with recent linux-2.6 git tree, this should be fixed.
