Debian suddenly lost graphical interface

Postby victor_dy » 2020-12-28 22:25

My vm runs on a debian os and it has worked well until suddenly the window keeps flashing. I turned it down and then when I came back and re-logged in, the graphical interface is gone. Now the logging in is shown as :


Info :

debian : debian-10.7.0-amd64-xfce-CD-1.iso for Debian ISO image
host : Win 10
virtualbox : VirtualBox 6.1.16

Any idea what happened and how to fix this ?

PS: it seems that the case happens when it's going to idle mode.
PS2 : if I logged in in the no-GUI mode, and use command `startx`, I will enter into the graphical interface, but with no response at all, except the mouse could move.
PS3 : I also notice that in start-up, there seems to be some `sensor not found error`[![enter image description here][2]][2]

Perhaps letting us know what GUI took a Yuletide holiday might help.

Did you check the X.Org log after running 'startx'? It should be under ~/.local/share/xorg/.
