    Freeze Report Ubuntu 21.04

    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.

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