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.
