Well let's confirm that it really is the same problem. Can you show us your /var/log/Xorg.0.log file and the output of 'glxinfo'?

This is a kernel problem with the new Core i3/i5/i7 integrated graphics. I just bought a HP DM4-1265dx with the same or similar setup and I am experiencing this issue with a number of Distro's . Most all of them, in fact.

The laptop boots up ok with what looks like no video. Goes blank when KMS kicks in. Using the function keys I had to turn up the brightness after each boot.

My temporary fix, for the moment, is a

echo 6 > /sys/class/backlight/acpi_video0/brightness

in my /etc/rc.local

I'm on ArchLinux, as I always intend to be, kernel 2.6.37. I may try 2.6.38 or there is a 2.6.36 in the AUR that claims to fix this issue.

The joys of new and better hardware!
