Comment 8 for bug 740893

Hey

I have the same laptop and have the same problem when i updated the Kernel.

I've been running 2.6.35.22 which has no problems.

I initially updated to 2.6.38-8 which i thought at first had failed, but noticed the screen was only usable (and i use that word very lightly) in direct sunlight.

I've now updated to 2.6.38-10 which has the same problem as 2.6.38-8, no back light on the monitor.

I'm currently viewing the laptop on 2.6.38-10 through an external monitor so i can try to resolve the problem and can run any diagnostic commands you require.

My onboard graphics card is the same and as follows with [sudo lshw -c display]
