I have just replaced the screen in my laptop because the last one cracked after years of loyal service. At first boot everything worked, except it is not possible to choose a resolution higher than 1366x768. To fix this problem I found this thread which offered solutions: https://askbot.fedoraproject.org/en/question/82840/how-to-provide-unrecognised-monitor-parameters-so-that-i-will-be-able-to-change-screen-resolution/
The answer in that topic shows how to add custom resolutions with
xrandr. However, I can manage the first few steps provided, but in the last one I get an error that I haven’t been able to find any information on.
In this last step I type:
xrandr --output XWAYLAND0 --mode "1920x1080_60.00"
the output I get is:
Blockquote X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 139 (RANDR)
Minor opcode of failed request: 21 (RRSetCrtcConfig)
Value in failed request: 0x0
Serial number of failed request: 22
Current serial number in output stream: 22
xrandr I get:
Blockquote Screen 0: minimum 16 x 16, current 1366 x 768, maximum 32767 x 32767
XWAYLAND0 connected 1366x768+0+0 (normal left inverted right x axis y axis) 340mm x 190mm
So it seems
xrandr --newmode and
xrandr --addmode have done their job, but some other step is required before
xrandr --output will work.
Is there anyone who can help me out to fix this?
Thanks in advance.
