wlsunset runs fine until the failed message after which the gamma is returned to the daylight default.
setting temperature on output '47' to 4689 K
setting temperature on output '47' to 4665 K
gamma control of output 47 failed
setting temperature on output '47' to 4641 K
I've even created a script to automatically restarts wlsunset after it stopped working:
#!/bin/sh
while wlsunset -l 46.8 -L 8.5 2>&1| read line; do
echo "$line" |grep -q failed && pkill wlsunset
done
This problem also happens with redshift. This problem also happens if I change to another location.
Does not happen any more.
