Frozen login screen BUT system is running

Post by czezz »

Hi everyone,

Host: Win10
Guest: Xubuntu 18.04
Vbox Version: 6.1.18 r142142 (Qt5.6.2)

This VM was running for years with no issue and only today this happened and it applies only to this specific VM:
Once Xubuntu 18.04 is booted I get login screen which seems to be frozen - I cannot enter my passwd, mouse cursor is not an arrow but like a pipe BUT I can see that
clock is working.
Also I can SSH to the system.

Any idea what might be wrong / where to look?

[UPDATE]
Once I connected with VNC i can see it complains about light-locker. I removed it but it didnt help. It also didnt help to install it back again.

The VM's name is not a hackable piece of information.

Start the VM from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the VM from within the VM's OS if possible. If not possible, close the Virtualbox window for the VM with the Power Off option set.

Right-click the VM in the main Virtualbox window's VM list, choose Show Log. Save the far left tab's log, zip it, and post the zip file, using the forum's Upload Attachment tab.

Also, check if the VM's disk is almost or completely full.

Hi everyone
I just wanted to let u know that this issue has nothig to do with VirtualBox.

In many/most google searches people were talkig about removig / reistalling / dowgradig nvidia drivers (as it is conflicting with display server).
In my case, this was a problem due to messed up/broken xserver-xorg-* packages (not VGA drivers).

Code: Select all

xserver-xorg-*
eg:
xserver-xorg-video-intel
xserver-xorg-input-all
xserver-xorg-video-vmware
In case Debian-like distros here is the fix (at least how I solved problem on my OS - Ubuntu 18.04):

Code: Select all

1. Boot system in to recovery mode:
In the GRUB menu, choose Advance options for Ubuntu > select kernel with "recovery mode" 
2. Enable network
3. dpkg Repair broken packages
4. proceed to normal boot / reboot
Hope this helps to someone.
Cheers
