Title:
unity dialogues split between 2 monitors
Status in gtk+3.0 package in Ubuntu:
Incomplete
Status in unity package in Ubuntu:
Incomplete
Status in xorg package in Ubuntu:
Incomplete
Bug description:
Since upgrading from Ubuntu 15.10 to 16.04, Unity is now shown across
both my monitors in a hard to use manner: unity dialogues, such as the
log-out and shutdown popups, are displayed centered between both
monitors, so the left half is on one monitor, and the right half on
another. Also, the unity top panel indicators and clock used to be on
both monitors, but are now only on the right monitor.
More info since it is likely relevant:
I have a Dell laptop with an NVidia Prime GPU and Intel built-in GPU. This
laptop has always been trouble configuring for dual monitors. The
nvidia-settings controls only shows one monitor, though it is supposed to show
two. I have never been able to get a working xorg.conf for the two monitors,
despited 2 days of trying (and I am a software developer well versed in reading
docs). The instructions in the nvidia docs simply don't work as stated for this
hardware (Dell XPS 17 L702X). Purging all graphics settings doesn't help.
Upgrading to a newer nvidia driver didn't help (I've tried the latest official
nvidia package as well as one newer). As a result, I've been using an xrandr
command and compiz display settings since Ubuntu 15.10. This worked perfectly
in 15.10. But, as stated, the unity top panel and dialogues are not working
properly in 16.04.
I tried Nvidia 361.42 and 364.19 from the PPA at
http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu.
The xrandr command in use is:
xrandr --fb 3520x1080 --output HDMI-0 --preferred --primary --mode 1920x1080
--pos 0x0 --panning 3520x1080+0+0/3520x1080+0+0/0/0/-3520/0 --output LVDS-1
--mode 1600x900 --pos 1920x180 --panning 0x0
(I know the fb sets up a wide virtual screen, but as stated, in 15.10,
that worked perfectly for unity)
In compiz display settings I have the following "Outputs" set:
1920x1080+0+0
1600x900+1920+180
It would appear in 16.04, Unity ignores the compiz outputs whereas in
15.10 it does not. But that's just a guess.
Sorry I cannot get a screenshot of the dialogues. They seem to block
Ubuntu's screenshot program due to their modal nature.
