I start with brand new Xubuntu 19.10 (I come from Windows 10).
With my laptop (MSI GS75 Sealth 85F), I have a problem during sleep when I close the cover:
First of all when I close the cover of my laptop, my PC goes to sleep well and the screen locks well (in order to be "protected" by password). I want this, and that's what's configured in my settings. But when I open the cover of my laptop, the screen often freezes (blocking) ... I see the wallpaper of my desktop, I see my tabs in my taskbar open, I can move the mouse, but I can not click anywhere ... And the unlock screen (so that I can login) does not even appear ... To get out of this situation I have to press the power button for a long time to shut down my PC and turn it back on ...
Is there a solution please?
PS: i am French, sorry if i don't speak english well.
Thank you in advance.
