Package: src:linux
Version: 4.14.13-1
Severity: minor
Ever since a recent kernel upgrade (I *think* 4.13 to 4.14; if
necessary, I can check), on each boot, my LCD brightness gets
reset to the minimum.
This is annoying; I currently work around it by putting
cat /sys/class/backlight/intel_backlight/max_brightness \
>/sys/class/backlight/intel_backlight/brightness
into /etc/rc.local, but it makes it virtually impossible to read
boot messages.
Furthermore, I have a slight feeling that the maximum brightness
is lower than it was before, or compared to my IBM Thinkpad X40.
That being said, several minutes after booting, it seems to be
becoming a bit brighter, so it’s maybe only on a cold start.
