9.5.1, 9.5.2, 9.6.2 didn't run on ubuntu 20.04

Now I have few versions on my PC with various run problems:

9.6.2 - after run it asks about import settings and then nothing, no messages in console, no errors, no CPU usage. Software didn't exit, but didn't work as well.

9.5.2 - similar to 9.6.2, but it shows splash with "loading...". Have line "Sandboxing disabled by user." in console.

9.5.1 - opens schematic and pcb editor with last project at start, but there is no main window. Also shows splash screen infinitely.

9.5.0 - This version not fully work. Menu doesn't work, I see menu bar, but if I click on it menu going selected and nothing happens, no drop down part.

Did it work fine for everyone?

Where is log files or something like that can help me realize what actually going on?

OK. Solution is so epic that hard to describe.

Last part about menu got me curious and I get deeper about it. And what I found: https://forums.autodesk.com/t5/eagle-forum/no-main-menu-in-layout-or-schematic-editor-eagle-9-0-0-9-...

If you have more than one monitor (configured position not in a straight line) you might be stumbled about.

At start newer version of EAGLE ask you about importing settings from older version. And on systems with more than one monitor window with question might show in outer space. So there is no way to see it.

Just disconnect monitors, run EAGLE, answer the questions and put them back.

After all, menu still not work with monitors configured angled L like.
