Comment 4 for bug 1734271

Typing up notes as I do more tests.

OK, I can confirm that the hang/freeze still happens with latest updates as of 2017-11-28 15:56 UTC, using window manager Marco (Compton GPU compositor).

Upon switching to Marco No Compositor and logging then and logging in, the global menus disappeared from the top panel. After a full restart of the VM, the menus reappeared.

The hang/freeze also happens with marco-no-compositor.

Ctrl-alt-F1, log in, sudo killall lightdm, go back to X and the GUI is already frozen and I see two Network indicators on the top right instead of one. Hard-reset the VM. Open MATE Tweak, switch window manager to Marco (Software compositor).

Try Alt key, X freezes/hangs. Ctrl-alt-F1, sudo shutdown -r now. VM restarts, test Alt key again, freeze/hang --- *even though in a previous test the software compositor worked OK*.

This is a difficult issue to pin down because it is very inconsistent.

Are there any log settings I can enable that may help provide more insight?
