Hello,
My second monitor has stopped working after an upgrade to Fedora 26
using dnf system-upgrade.
Also, arandr is busted: here is what I get.
$ arandr

Exception: XRandR 1.2/1.3 required.
And here is the output from xrandr:
Does the external monitor switch work on your computer? Here it is the
<Meta/Windows> - <p>
keyboard shortcut
Careful: this switch can drive my CPU up to 100% load - I recommend
being logged in as root on a tty to be able kill the offending process
via htop or someth like that. Here the offender seems to be, IIRC
gnome-settings-daemon
I recommend a
tail -f /path/to/your/active/Xorg*log
and then see what happens there if you plug in the second monitor.
Watching journalctl (journalctl -f, IIRC) might help too ...
What GPU? To identify it:
lspci -nnk |grep -A 5 -i vga
Also: firmware for your GPU loaded? Someth. like:
dmesg | grep -E 'drm|amd' | grep -iE 'firmware|microcode'
(from
https://wiki.debian.org/AtiHowTo#Firmware )
I had my external monitor settings more or less broken/reduced in
functionality a few days ago after an upgrade from F24 > F25 ... still
hoping, in spite of your mail, that an upgrade to F26 fixes my problems.
I don't want to go back to F24 where a connect to an external TV monitor
worked very well with an AMD GPU.
