Dear all,
I have three monitors and I use /etc/X11/xorg.conf.d/10-monitor.conf to configure
these for xorg. I use xfce4. After I updated using pacman -Syu this morning I got
some new xfce4 packages and also a new xf86-video-intel package. Last time
I had updated was two weeks ago. My /etc/X11/xorg.conf.d/10-monitor.conf
looks as follows
Section "Monitor"
Identifier "DP1"
Option "Primary" "true"
EndSection
Section "Monitor"
Identifier "DP2"
Option "RightOf" "DP1"
EndSection
Section "Monitor"
Identifier "VGA1"
Option "RightOf" "DP2"
EndSection
After the update the rightmost 'VGA1' monitor no longer works. I can see
the windows that are on the non-working monitor on the workspace
switcher but the monitor itself is black. The most funny thing of all of this
is that if I move the mouse cursor completely to the right of the two
screens that work, some sort of one pixel wide shadow of the mouse is
visible on the screen that is not working. But the mouse cannot be
moved to the third screen despite the fact that the screen space of the
non-working monitor is present in the workspace switcher. Also, I know
that the third screen did not suddenly bread down because when I leave
X I see an identical text screen on all three of the monitors.
Also, I can see the third screen when I do xrandr --listmonitors. It says
Monitors: 3
0: +*DP1 1920/520x1200/320+0+0 DP1
1: +VGA1 1920/520x1200/320+3840+0 VGA1
2: +DP2 1920/520x1200/320+1920+0 DP2
Anyone any ideas about what to do?
Have a nice day,
Chris

Okay I now sort of solved this. It turns out that commenting out the third monitor in the file
/etc/X11/xorg.conf.d/10-monitor.conf makes them work all three just as before. Kind of weird
really.....
