Kubuntu 22.04 installed on SSD as only OS on old Lenovo V570c laptop.

xrandr output (part of it):
Laptop has these VGA controllers:
The problem is that some programs (Kdenlive, Openshot video editor) and some games (OpenMW, Assaultcube, UFO: AI) doesn't work. Some (kdenlive) say: that it's something wrong with display settings. Some (AssaultCube) work in background but doesn't show anything on screen. Or, for example, I hear music from OpenMW, but nothing on screen. And in settings it (OpenMW) offers to use "default resolution: 0x0", which seems strange. I can't recall what exactly I've been doing when these problems started.
In my opinion it connected with fact that xrandr tells about some VGA-0 connected, but I only have laptop screen and no external displays connected.
I tried to reinstall nvidia drivers but it didn't help.
So how can I get rid of this "ghost" VGA-0? Or where should I dig to understand the roots of the problem?
[SOLVED partly]: After looking through history of commands I could recollect that at some point I had installed SDL2 from sources (don't ask why). Uninstalling it solved a problem with programs and games not running. But mysterious VGA-0 still stays with me.
