View Full Version : Fedora 26 does not recognize the standard resolution for my monitor

29th October 2017, 06:43 PM
Good afternoon, fedora fellas,
I'm running fedora 26 on my computer and recently, my system stopped recognizing the standard resolution for my LCD monitor Samsung SyncMaster 933, which is 1360x768. Instead, what I get is 1024x768.

By tiping the xrandr command on a terminal, I get the following output:

Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
XWAYLAND0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1024x768 59.92*+

I've already tried to change the resolution manually, with the following code:

xrandr --newmode "1360x768_60.00" 84.75 1360 1432 1568 1776 768 771 781 798 -hsync +vsync
xrandr --addmode XWAYLAND0 "1360x768_60.00"
xrandr --output XWAYLAND0 --mode "1360x768_60.00"

But that renders me the following response:

xrandr: Configure crtc 0 failed

As a last resource, I've created the files 01-monitor.conf and 02-screen.conf in the folder /etc/X11/xorg.conf.d/, but that doesn't seem to have made any difference at all. You can check their texts right here:


Section "Monitor"
Identifier "XWAYLAND0"
VendorName "Samsung"
ModelName "SyncMaster 933"
HorizSync 31.5 - 80
VertRefresh 40 - 80

I've already searched for similar problems on the web, but it seems that none of the given solutions can help me.
I'd be extremely grateful for your answers.
