I have the same issue with Jaunty. I have also tested on Karmic and the bug is a bit different. First thing is that brightness can now go up to 15 instead of 13 in Jaunty (in /sys/class/backlight/acpi_video0/brightness). This matches what's reported in /proc/acpi :
cat /proc/acpi/video/VGA/LCDD/brightness levels: 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 100 current: 100 On Jaunty the levels only go from 20 to 85. So that's a good improvement. Second, I can now cycle through all the brightness settings but it's a bit random. When I press fn+home for the first time, brightness goes to 0. If I press it again it goes to 14. If I press fn+end and brightness is already at 15, it goes to 1. It goes back to 15 if I press it again. Third, I can have every brightness level but I need to hold fn+home or fn+end for a certain amount of time and release it. It seems that the key press is sampled too fast. -- thinkpad sl400 light control keys don't work https://bugs.launchpad.net/bugs/348348 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
