3. The unity menu or task switcher pop up or leave quickly
4. The menu or task switcher slowly fade in (or out) over the course of 5-7
seconds.
I'm running Ubuntu 16.04 with the latest updates on a 2009 Dell T5500
workstation with an nvidia Quadro NVS card. When I run the noveau drivers, I
get errors and lockups, so I run the nvidia 340 drivers (which are the
recommended ones). I've tried a few other versions of the drivers, and still
get the same issues.
The problem that I have is that on initial login, the Unity menu and
alt-tab switchers work quickly, but after I've left the X session up for
a while, they start popping up at about 1 FPS over the the course of
5-10 seconds. Switching to a different desktop (e.g. MATE) "fixes" the
issue, but I like the easy "search for applications" launcher that Unity
provides.
The dash "include online search results" is off, but I think that was a
red herring, given that the alt-tab switcher exhibits the same behavior.
I've tried toying with CompizConfig settings (e.g. Dash Blur, disabling
animations, etc), to no avail.
I just did a fresh install of 16.04 yesterday on a brand new, recent SSD, and
I'm getting the same issues, and I'd seen the same issue going back at least to
14.04.
Note that running $ unity --replace or compiz --replace does not alleviate the
problem for more than a couple of minutes.
I've installed the CompizConfig Settings Manager and tried disabling
anything that seemed relevant: Animations, Fading Windows, Window
Decoration, Dash Blur, etc. Even if I choose Enable Low Graphics Mode,
the affected windows don't pop up instantly. I've even gone into the
Ubuntu Unity Plugin and set all of the Menus durations to 0, to no
avail.
When running htop -d 1 (i.e. to get quick updates on the CPU usage in
tenths of a second), I see a brief spike in CPU utilization from compiz
and /usr/lib/xorg/Xorg during the issue, and compiz stays pegged using a
full CPU until the problematic window goes away. (CPU is 4 core
hyperthreaded Xeon)
If there exists a work-around, I've also asked a question on
askubuntu.com
