Running ubuntu hardy with a 2.6.25 kernel causes the backlight of my laptop to remain black after resume. Switching VTs does not help.
Hardy ships with a 2.6.24 kernel which works just fine, I installed a 2.6.25 kernel since it causes far fewer wakeups (as observed with powertop).
I have also tried the 2.6.24 kernel with drm modules from git. This also fails on resume.
The laptop is a dell xps m1330 with an x3100 chipset.
Any ideas?

Khashayar
