Description Cameron Cross 2009-03-05 07:32:40 UTC
Description of problem:
Laptop screen brightness is set to lowest on boot up

Version-Release number of selected component (if applicable):
2.6.27.19-170.2.35.fc10.i686

How reproducible:
consistently

Steps to Reproduce:
1.update to the kernel 2.6.27.19-170.2.35.fc10.i686
2.reboot on a lcd screen that can have the brightness changed via software
3.struggle to see the cursor
  
Actual results:
boots up with a dimmed screen

Expected results:
boots up with a significantly brighter screen

Additional info:
previous kernel hasn't got this problem
if I press the increase brightness button on my keyboard, nothing happens and the gui shows that the screen is on full. But if i press the decrease brightness button on my keyboard, the screen goes to the second highest level and the gui shows the second highest level and then i can increase it to the full brightness.

Hi,

It seems my problem (https://bugzilla.redhat.com/show_bug.cgi?id=490608) is the same as this one. Do you have an ASUS laptop too ?

Cheers.

Hi,

A new kernel has been released and the problem is still occurring.

Here is something new (I hope): When I boot on the last kernel where the problem was not (never) occurring (ie 2.6.27.15-170.2.24.fc10.i686) and I reboot on one of the two last kernels (2.6.27.19-170.2.35.fc10.i686 or 2.6.27.19-170.2.35.fc10.i686) the problem does not seem to occur; the brightness is correct from the beginning of the boot. Can it be that the problem is linked to something that might happen when shutting down the computer and not something happening at booting time ?

I hope someone is looking at this problem.

Thanks and regards.
Lilian
