Binary package hint: gnome-power-manager
I have a fresh installation of Hardy with the latest updates installed on a Dell Inspiron 6400 laptop. The brightness settings (Fn+Up/Down) work although they seem to skip a level each time.
'/proc/acpi/video/VID/LCD/brightness' tells me that it supports brightness levels 12, 24, 36, 48, 60, 72, 84 and 100. Without gnome-power-manager running pressing Fn+Up will transition up into each level and back down again smoothly.
When gnome-power-manager is running increasing the brightness from 12 I can only get levels 36, 60, 84 and 100. Decreasing the levels from 100 I only get 72, 48, 24 and 12. Running gnome-power-manager with the verbose option shows that when I press the brightness-up button once it is recorded twice. I ran gnome-power-manager in a debugger thinking it was a timing issue and it still happened.
I have included the output from pressing the brightness-up button (Fn+Up) once below. This only happens when gnome-power-manager is running and did not happen using Feisty. I have looked at the code and I cannot see why the button event is triggered twice, I don't have any experience of the code but if you can give me any ideas of where to start I can look into this myself.
Thanks!

this is actually caused by a BIOS bug/kernel bug (depends who you talk to). It's because the BIOS has tables in the DSDT to represent the possible different video cards that would ship with the box (UMA or discrete). There is a fix available upstream, but it causes regressions on other machines. It will need to be tracked until it's ready. |
