Package: xbacklight
Version: 1.1.2-1
Severity: normal
Dear Maintainer,
on my Lenovo T410 with an Intel graphics card, xbacklight modifies the values
in /sys/class/backlight/acpi_video0 instead of
/sys/class/backlight/intel_backlight . The latter works just fine, whereas
changing values in the former has no visible effect.
Since my KDE session seems to use xbacklight upon login to restore the old
backlight, this results in a totally black screen, because the intel value
seems to be initialized to 0. Pressing the brightness up and down keys has no
effect either, so the only way to recover from this is to change the values in
/sys/class/backlight/intel_backlight by hand.

That's not a bug in xbacklight, it's either a bug in your kernel or X
driver.
