Black screen on OpenSUSE Tumbleweed Linux

I have Alienware m15r7 which has RTX 3060.

0000:00:02.0 VGA compatible controller: Intel Corporation Alder Lake-P Integrated Graphics Controller (rev 0c)
0000:01:00.0 VGA compatible controller: NVIDIA Corporation GA106M [GeForce RTX 3060 Mobile / Max-Q] (rev a1)

When I install and use drivers (nvidia-glG06) Linux doesn’t see KDE desktop but it is not disabled, I have a mouse pointer, and I see a _ on the top left of the screen.

When I switched to tty1 and killed the startplasma-x11 process (actually, it should have restarted startplasma-x11), the KDE desktop reappeared.

I looked at other threads and tried their solutions, but none of them worked.
