Green "boxes" on desktop after upgrading from eoan to focal

I also tried creating another account just in case the issue stems from my account config but the problem persists.

What is the output of:

sudo lshw -C display; lsb_release -a; uname -a; sudo dmidecode -t 1

Thanks

Hi

Also here's a screenshot of what I see:

Does it happen on all screens? If you set a different refresh rate is it different?

Hi
Not sure what you mean by screens. Do you mean monitors? If so, I only
have one.Happens even if I change the refresh rate.
Here's what I figured out so far.
When I login, it only happens if I choose any of the following from the
gear icon at the bottom right corner of the login screen:- GNOME
Classic- GNOME on Xorg- Ubuntu
It doesn't happen if I choose:- GNOME- Ubuntu on Wayland
I wonder if the stemmed from the fact that I upgraded from eoan. Old
incompatible configs perhaps?

Yes, monitor = screen.

If you use the additional drivers app does that help?

monitors = screens. Gotcha. That said, I only have one.
Tried the additional drivers but the only thing there is the wifi
driver.

Ubuntu 20.04 LTS (Focal Fossa) Daily Build has not been released yet. 23 April 2020 is the Official release date.
This is a Developmental Branch OS at this point. File any necessary bug reports that may occur.
This build changes on a daily basis with a new build. Suggestion is to reinstall after the new LTS Release is out.

Gotcha. Just to clarify, are you suggesting that I file a bug report after
the official release provided that the problem still persists or should I
file the bug report now?

Hi

Just wanted to make a quick update on this one. Here's what I did to "fix" this.

sudo apt remove --purge xorg xserver-xorg gnome-session ubuntu-desktop-minimal ubuntu-desktop gdm3 xwayland
sudo autoremove --purge

# unsure if the following two mv steps were necessary
mv /etc/X11 /etc/X11.bak
mv /usr/share/X11 /usr/share/X11.bak

sudo apt install gnome-session ubuntu-desktop-minimal

# this is i had to do as it seems I lost keyboard config when I did the above mv
sudo apt install --reinstall xkb-data

reboot

All is well now. Posting this here for reference.

Great share. Hopefully this will help others
