I'm obliged to use the onscreen keyboard (i.e Onboard). I decided to update my PCs to Ubuntu 20.04 LTS.
However, I'm facing problems with the on-screen keyboard with all of them
- It's impossible to use the on-screen keyboard to log in - it appears on the login screen but it doesn't work
- Once I'm logged in, the keyboard does not stay floating at the bottom of the screen, but becomes stuck and pushes all my screen content up and my desktop becomes unusable.
I downloaded the keyboard that was available in 16.04. I also tried a fresh install on one of the machines. But the same issues persist.
I've tried:
- Ubuntu 18.04 keyboard and mouse not working at login screen No change for me, still impossible to use the on screen keyboard for log in.
- Keyboard not working after update to 18.04 same, no change
work PC:
- intel i5
- 16g ram
- nvidia 1050
wife's PC
- intel i3
- 8g ram
- nvidia gtx
If anybody has any idea how to get the keyboard to float over the content instead of getting fixed I would be very thankful.

onboard? From the Ubuntu repository 'universe', or from some other source? If you really used the version from 16.04, you can expect problems, because it was made for another version of Ubuntu. Which version is it? Please check with the commandapt-cache policy onboardif you installed from a repository. – sudodus Jan 28 '21 at 15:57
