After putting the system to suspend this won't work. Also after a second time putting to suspend it won't work. Reproducible: Always Steps to Reproduce: 1. Restart if you've done a suspend recently. 2. Try Adjusting brightness (on my Notebook using Fn+F6/F7), this should work. 3. Put the system to suspend mode. 4. Wake up the system from suspend and try the steps named in 2 again Actual Results: In both cases (before and after suspend) the KDE brightness widget is shown correctly but brightness won't change after suspend. Expected Results: Adjusting brightness should work like after a fresh restart. System: Toshiba Tecra R850-11M openSuse 11.4 / 2.6.37.6-0.7-desktop / KDE 4.7 The actual state is also after a suspend shown correctly in the following file: cat /proc/acpi/toshiba/lcd brightness: 5 brightness_levels: 8 When adjusting the brightness using the keys the value in the file above is actualized corrctly. In /var/log/messages and dmesg (also as attachment) the following line appears: Aug 9 20:38:02 linux-h81p kernel: [ 899.913018] ACPI: Failed to switch the brightness -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
