I have a problem with ctr+alt+f4 in 5.20 that I use for the moment. Modifications are ok,
but anyway not possible inside games. And when I want to go out, the x86 64 version is hanging.
Black screen and flashing cursor down at the begin of the last line.
Necessary to push reset button. I have no idea if I am the only one with this problem, or if resolved in 5.21
And after, sound is away but comes back with a putty connection and alsctl restore.
