Deleting specific display setting created with xrandr

Question

I want to delete a display setting which I set up via xrandr to my Linux Mint distribution.

xrandr --rmmode 1368x768_60.00

gives me this error:

X Error of failed request:  BadAccess (attempt to access private 
resource denied)
Major opcode of failed request:  140 (RANDR)
Minor opcode of failed request:  17 (RRDestroyMode)
Serial number of failed request:  32
Current serial number in output stream:  33

I also tried it with sudo , which prints out the same error.

Besides that I also deleted my monitors.xml file, with no effect.

How can I properly delete my display setting 1368x768_60.00 ?

Solution 1

Try this

xrandr --delmode <output> <name>

for example:

xrandr --delmode HDMI-1 1368x768_60.00

Solution 2

As ctac_ already mentioned, the mode has to be unused. So I switched to another mode, used xrandr --rmmode 1368x768_60.00 which nevertheless has thrown an error and still showed the mode in the display settings.

Rebooting after that helped, and the mode wasn't available anymore.

I think the problem come from : --rmmode name This removes a mode from the server if it is otherwise unused. Try to start on another mode.

@ctac_ you are right, that helped me solving the problem.
