### Problems with Resolution and My Monitor in Fedora Core 25

Well, my monitor always has been a bit of a problem child, but it worked, so I didn't mind.

I let it bounce once on the floor, but besides some slight discolouring in the lower-right corner, it was fine.

It reports EDID settings that are completely crap, but I got used to ignoring those, using xrandr.

# XRandr settings that work for me

The following settings work:
xrandr --newmode "1920x1440" 339.50  1920 2072 2280 2640  1440 1443 1447 1514 -
xrandr --newmode "1600x1200" 235.00  1600 1728 1896 2192  1200 1203 1207 1262 -
xrandr --newmode "1280x1024"  159.50  1280 1376 1512 1744  1024 1027 1034 1078
xrandr --output VGA-0 --mode 1920x1440

# Problem

Then I upgraded to Fedora Core 25, and my monitor showed me a handsome 1024x768, which was a disappointment to say the least. (I'm used to 1920x1440.)

Using xrandr gave me the cryptic error message:
bash-4.3$xrandr --output XWAYLAND0 --mode "1920x1440" xrandr: Configure crtc 0 failed After some research I noticed that Fedora Core 25 is the first one to use Wayland1 as the default. # Solution Switching back to the old Xorg2 fixed my problem. # Checking graphics card bash-4.3$  lspci -nnk |grep -A 3 -i vga
