reinstall qt6 after chrome os linux rebuild fixes qt6 platform error; but gives to other errors.

Received an update to linux beta, from Chrome OS.
The update rebuilt the linux environment.
I re-installed qt6 creator.
My previous situation of not being able to find a platform was fixed.
I immediately tried to run a test of a new (vanilla) qt quick UI prototype project.

The immediate result was that Qt could not load/find libOpengl0. It was not defined.
I ran sudo apt install libopengl0. This fixed that situation, but resulted in a previous
error related to "keyboard" and "<CAP>"; and the min/max controls in the
title application area does not work.

See snapshots for more detail.
