When I start my Ubuntu 20.04 normally, I get an (backlit) black screen.
When I hold Shift during startup, I can see the grub startup menu:
I can choose "advanced options" and then the recovery mode and it starts with a low-resolution and without internet.
I have purged all nvidia drivers in the hope that this would fix the issue. It didn't. What can I do?
What I've tried
When I replace "quiet splash" by "nomodeset" in the boot options, I get the following instead of a black screen:
I can also switch with Ctrl+Alt+F1-F7 and I see that something changes, but I cannot read anything.
Internet in Recovery mode
With this guide I could get internet in recovery mode. I could install another nvidia driver, but it didn't help :-(
Defect graphics card?
Could it be that the nvidia graphics card broke and the Intel "on-board" graphics chip still works?
Within the recovery mode, I get:
$ nvidia-settings ERROR: NVIDIA driver is not loaded ERROR: Unable to load info from any available system (nvidia-settings:4594): GLib-GObject-CRITICAL **: 11:34:54.538: g_object_unref: assertion 'G_IS_OBJECT (object)' failed ** Message: 11:34:54.541: PRIME: No offloading required.
