[Bug 1389215] Re: Brightness controls are not working in Unity / Xorg because of Nvidia proprietary driver.
** Tags added: needs-vivid-test
** Changed in: xorg (Ubuntu)
Importance: Undecided => Low
** Changed in: xorg (Ubuntu)
Status: New => Incomplete
** Description changed:
Brightness controls are not working in Unity / Xorg. When pressing the
keys <fn><home> and <fn><end> on my Lenovo W510, I see the indicator on
the screen showing the level of brightness changing, so key mapping is
not the problem. However, the brightness is not changing.
On the kernel level, I have the single following device:
# cd /sys/class/backlight
# ls -l
total 0
lrwxrwxrwx 1 root root 0 Nov 3 17:16 acpi_video0 -> ../../devices/pci0000:00/0000:00:03.0/0000:01:00.0/backlight/acpi_video0
When playing with the <fn><home> and <fn><end>, the value of
/sys/class/backlight/brightness changes accordingly. The screen
brightness does not change.
Performing:
# echo 10 >brightness
...does not have any effect (regardless of the value provided, 10 being
just an example).
WORKAROUND
There is an odd workaround. Simply go to the console using
<CTRL><ALT><F1> and using the <fn><home> and <fn><end> keys, brightness
then changes. Return to Unity / Xorg with <CTRL><ALT><F7> and the
selected brightness persists.
NON WORKING WORKAROUND
On the web, I read that adding:
Option "RegistryDwords" "EnableBrightnessControl=1"'
in xorg.conf might fix the problem. I do not have an xorg and when I
let the proprietary Nvidia driver generate one and add this option, X
does not start anymore.
