I recently upgraded to Ubuntu 21.04 from Ubuntu 20.10. I already had programs installed that I kept with the upgrade. Subsequently, I then installed BOINC Manager and the associated client software. I used the command line: sudo /etc/init.d/boinc-client start to start the client for BOINC. I then connected to my Einstein@Home account using BOINC Manager. The packages loaded as usual. I started the screen saver (rotating astronomy sphere). Then within a couple of minutes my entire computer system freezes.
I have tested my various other installed programs for astronomy and they all work just fine and do not freeze my system.
My system is as follows
Intel® Core™ i7-4500U CPU @ 1.80GHz × 4
7.7 GiB Memory
Intel® HD Graphics 4400 (HSW GT2)
1.0 TB HD
Ubuntu 21.04
64-bit
GNOME Version 3.38.5
Windowing System Wayland
To check the version of BOINC Manager I had to start the the program which froze my system before I could add the following:
BOINC Manager
Version 7.16.6 (x64)
wxWidgets 3.0.5

Change back to X.org WDM and I bet the screensaver works and doesn't freeze the system.
Hi Keith, Thanks so much!

Hi Keith,
Thanks so much! I made the change suggested and yep, No freeze with BOINC and Einstein@Home screen saver!

Glad to help. Pretty sure Wayland was the issue. The old screensaver using X.org OpenGL was the situation that Wayland couldn't handle.
