On my just-released Dell XPS 13 Ultrabook, I can control the backlight |
2 |
with 'xbacklight -set 0' and 'xbacklight -set 100'. Any other values |
3 |
cause the screen to blink and flash. The keyboard backlight shortcuts |
4 |
don't work unless I map them to xbacklight 0 and 100. Also xbacklight |
5 |
doesn't work at all if I'm unplugged from AC. I've tried |
6 |
acpi_osi=Linux and acpi_backlight=vendor in grub.conf. acpi_osi |
7 |
doesn't seem to make any difference and xbacklight doesn't work at all |
8 |
without acpi_backlight. Do I just need to wait for a newer kernel? |
