Hi All,
I used to use this command to change the brightness of the screen: xrandr --output eDP1 --brightness 0.9
After an update, it didn't work anymore. The error message is:
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 21 (RRSetCrtcConfig)
Serial number of failed request: 36
Current serial number in output stream: 36
eDP1 is still correct. Does anybody know what's wrong?
Regards.
Solved: restarting the machine solved the issue.
