When i try to change display brightness using keyboard
switches it goes to lower value and does not grew up!
If i use the slider on applet it works perfectly! My hardware is an HP Pavilion dv5000(dv5245ea) Doing some searches i found this http://bugzilla.gnome.org/show_bug.cgi?id=469748 as solution for my problem. Attached there is the patch used by me. Additional info: * gnome-power-manager-2.20.0-1 Steps to reproduce: Try to change display brightness using keyboard |
This task depends upon
brightness.patch (1.1 KiB)
So the only workaround for me is using the attached patch that fix a communication problem between hal 0.9.10 and gnome-power-manager.
I also tried gpm-2.20.1 but without any patch it does not work!!
more details:
- removing video module prevents brightness keys from working at all (they stop generating any event whatsoever) so this is NOT a workaround.
- with video module but without g-p-m (either not started or jsut by killing it), brightness keys work exactly as expected.
- with video module and g-p-m, brightness keys work, but brightness is set incorrectly, as described above and in gnome bugzilla.
I will try attached patch and report.
Some computers have an AC event occuring in ACPI from time to time (as if the plug had been un-re-plugged), and this may trigger a re-set of related functions, incl. brightness.
Check your ACPI log for such an event.
gpm 2.20.2 works without any patch
