unity package

Workspaces, Launcher placement, Sticky Edge stopped working, 16.04.1

Asked by Alex Villeneuve

I've recently update Ubuntu 16.04 using the dist-upgrade commands. Some settings suddenly stopped working, such as Workspaces, Launcher placement (always display on all monitors) and sticky edge is always on.

I've formatted, reinstalled Ubuntu 16.04, everything works until I run dist-upgrade, then after reboot the problems return. I haven't modified or installed anything to modify the core of Ubuntu. The only thing I have installed are my development software (Git, Atom, GitKraken, Browsers, MySQL Workbench, Docker, Docker Compose)

If I run this command:

dconf read /org/compiz/profiles/unity/plugins/unityshell/num-launchers

Will return the right value, either 1 (if I set launcher on one screen) or 0 (if I set the launcher on all screens).

dconf read /org/compiz/profiles/unity/plugins/core/hsize
dconf read /org/compiz/profiles/unity/plugins/core/vsize

Both return 2 (if I tick Enable Workspaces) or 1 (if I untick Enable Workspaces)

So I'm guessing the settings actually get changed, but they are getting ignored for some reason?

I've recently reinstall 16.04 and updated package by package to pinpoint the issue. It appears after I update the unity package.

After verifying the system info, I noticed that Ubuntu wasn't seeing my graphic card properly (I had the nouveau display driver installed - Gallium 0.4 on llvmpipe (LLVM 3.8, 256 bits)). Once I switch the driver for the NVIDIA binary driver (version 361.42) and rebooted Unity started to work properly.
