Recently I decided to try KDE Neon again. I tried KDE Neon in the past and had too many problems with my hard drive, but I decided now to try KDE Neon again because I really like KDE.
I have Nvidia GeForce GT 630m hybrid graphics.
At first everything seem to work fine until I installed Nvidia driver.

What I did:

I installed Nvidia driver with the command (of course I checked that Nvidia card is recognized by the system before)

Code: Select all

sudo ubuntu-drivers autoinstall

In ubuntu that what I was always doing and it worked fine.
At first everything worked fine KDE was crashing from time to time though.
Until one day my system didn't boot up I was just getting black screen couldn't even go to tty session I had to cut the power in order to shutdown.
Finlay I managed to boot into tty through the recovery mode and changed Nvidia Prime to Intel and managed to boot up.
The weird thing is that if I purge Nvidia driver I'm getting the same black screen.

What I have tried

I tried to purge Nvidia driver and install again (as a mentioned for some reason my laptop can't boot up without Nvidia driver)
I tried this solution from Ubuntu forum to delete the alternatives with the command:

Code: Select all

sudo update-alternatives --remove x86_64-linux-gnu_gl_conf /usr/lib/x86_64-linux-gnu/mesa/ld.so.conf


But it didn't help I was getting the same black screen when Nvidia Prime is set to Nvidia.

It seem that when Nivdia card is on opengl is disable.
is anyone know how can I make Nvidia card to work in KDE Neon?
