blank screen after logging in

Postby canti » 2018-09-14 07:02

Dear all,

Since one week I face a blank screen with mouse cursor only (movable cursor, but can't do anything with this). Before that everything went fine. It seems that a regular update broke something with the graphical Gnome 3 environment (from previous posts here I read it is probably caused by the update of Xorg). In the login screen I have the following options to select:
    Default Xsession
    Gnome flashback (metacity)
    Gnome
    Gnome on Wayland
    System default X11 default
The first, the third and the fifth option results in blank screen as described above. The second option went smooth and I can enter in the Gnome flashback environment which is similar to Gnome 2. The fourth option results in turning back automatically to the login screen after showing a blank screen for one, two seconds.

This does not matter if I am using gdm3 or lightdm: the results are the same.

I use Debian stretch with Gnome 3.

Few outputs for information:
lspci -nn | egrep -i "3d|display|vga"

I have bumblebee installed.

What can I do to get Gnome 3 back?

you have to fix your graphics session to support hardware accelaration.
not sure how to do this with dual graphics...

Yes, it could be something with the hardware acceleration. Bumblebee issue? Nvidia issue? When I tried with "rmmod nvidia" within tty, I got the message that nvidia was not running. I don't know what to do. Or just wait until the new update of xorg? I hope someone can help me here...

Thanks for the link to the startpage. Running the intel gpu and Nvidia gpu seem fine:

shows that bumblebee works well with the Optimus system.

On https://github.com/Bumblebee-Project/bbswitch#disable-card-on-boot I see a possible solution to disable card on boot and see what happened. I hope I will not break the system. But as I'm not highly experienced Debin-user, I'd like to know first your opinion based on above. And if agreed to use the possible solution, should I create /etc/modprobe.d/bbswitch.conf and add there "options bbswitch load_state=0"?
