Public bug reported:
I've recently switched from 16.04/Unity to 18.04/Gnome3, with new
hardware (a Lenovo Thinkpad T470s) used mostly with a docking station
and external keyboard.
I do heavily use of in-workspace windows switch (eg, Alt+Esc) and i've found
that every time i press Alt+Backslash (in Italian keyboard layout Backslash is
all left, between TAB and Esc keys) my session ''lock up'': i can switch
between windows, i can use the gnome shell and the top bar (status bar?), i can
even run other application (via Alt+F2 or gnome shell menu) but every window
(old or new) are ''locked'', like there's no focus: no keyboard nor mouse
interaction is possible.
Application are not 'locked', they continue to run, but there's no way to
interact with them.
I can also lock the screen, or put the system in standby: i can awaken
from that, insert the password but still no focus on windows.
The only solution: logout.
I've also tried to define a keyboard shortcut to map Alt+Backslash,
but... gnome keyboard configurator locks as every other window when i
press the keys.
Please, help me at least to disable that 'killer' keyboard shortcut! ;-)
Thanks.
