Public bug reported:
Ubuntu 16.04 with two identical nvidia cards and four identical LG monitors.
At the graphical login screen only the first 3 monitors appear alive (i.e. have
backgrounds and the mouse can move to them). A pop-up appears:
"Could not switch the monitor configuration" (bold text with do-not-enter icon)
"could not set the configuration for CRTC 64" (normal text)
After logging in (gnome flashback Metacity session) the same 3 monitors
are alive and the same pop-up appears.
Using Applications > System Tools > System Settings > Displays,
the 4th monitor is shown in grey and when clicking it, it shows that the slider
is off. When turning it to On (leaving default resolution and rotation) and
clicking Apply
"The selected configuration for displays could not be applied" (bold text with
do-not-enter icon)
"could not set the configuration for CRTC 64" (normal text)
a few seconds later (if the first one is not closed) another pop up with
do-not-enter icon:
"Failed to apply configuration: %s"
"Timeout was reached"
or trying again, if the first pop-up is closed within a few seconds, the
second one is
"Failed to apply configuration: %s"
"GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._gsd_2drr_2derror_2dquark.Code2:
could not set the configuration for CRTC 64"
...and the Displays GUI makes it look like the 4th monitor is enabled
but it is still blank.
At the time of doing this, /var/log/Xorg.0.log shows:
[ 96283.251] resize called 7680 1080
[ 96283.299] Cannot do multiple crtcs without X server dirty tracking 2
interface
[ 96283.299] randr: failed to set shadow slave pixmap
[ 96283.300] (EE) NOUVEAU(G0): failed to set mode: No space left on device
I have also tried this with xrandr command line:
$ xrandr --output DVI-I-1-4 --right-of DVI-I-1-3 --auto
xrandr: Configure crtc 3 failed
...and the Xorg.0.log at this time is almost the same as above, plus the
(I guess) fall back resizing to 3 monitors (5760x1080):
[ 96645.224] Cannot do multiple crtcs without X server dirty tracking 2
interface
[ 96645.224] randr: failed to set shadow slave pixmap

[ 96645.229] resize called 7680 1080
[ 96645.281] resize called 5760 1080
I have previously tried to get around this with /etc/X11/xorg.conf with various
Xinerama or ZaphodHeads settings but at the moment (of starting this
"ubuntu-bug xserver-xorg-core" report) I have no xorg.conf and no
~/.config/monitors.xml. Obviously monitors.xml has been re-created as I test
the Displays GUI to describe the pop-ups above, but it was not there at login.
The 2-connector video cards to all four monitors are connected with DVI
cables. The monitors are LG E2240TI, the video cards are (lspci):
