Public bug reported:
Binary package hint: xfce4-power-manager
Bug description:
When I start my laptop usually the screen brightness is set to minimum. I have
xfce4-power-manager running in e17. However trying to increase the screen
brightness using the function keys fails.
Running xfce4-power-manager --no-daemon in a terminal gives the following
output:
(xfce4-power-manager:2106): xfce4-power-manager-WARNING **: could not
map keysym 1008ffa8 to keycode
and pressing one of the brightness function keys results in a segfault
.
However after setting the brightness manually via: echo 7
>/sys/class/backlight/sony/brightness
xfce4-power-manager works fine and setting the brightness works.
Backtrace attached.
** Affects: xfce4-power-manager (Ubuntu)
