Running Ubuntu 22.10, Mate desktop environment. I installed boinc-client and boinc-manager via apt. All works fine in this pre-release version of BOINC (7.20.2+dfsg), except, when I open the Computing Preferences, I get a blank dialog box, with only the window controls in the title bar.

Searching here I found question 1134597 (Unable to access settings of the BOINC manager), which seems to be the same issue from 2019, never answered.

For the time being I used cpulimit to force down CPU usage, but that's not a very polished or ideal way to handle this.


  • Today it's mysteriously working. I have no idea what changed.

  • When you say "settings" are you talking about the "Computing preferences" or another menu? Does this happen with any other software? I wonder if it is a driver/library issue. Does lowering the CPU usage fix this issue? I also wonder if you are better off with a Long Term Support Version (LTS) of Ubuntu; I use LTS 22.04 with Boinc 7.20.5 (x64) and all the preferences and option menus work.

  • It has been long enough now that it is irrelevant. Several versions of the client and a new OS later, it works as designed. I did mean Computing preferences.

  • OK, this is just bizarre. I set up a completely new system and ... computing preferences remains blank. I9 with nVidia GPU, might be useful to the project if they'd accept my help, darn it.

As of this exact moment on Debian bookworm, I got the blank Computing Preferences dialog from the simple view of the BOINC Manager. If I switch to the Advanced View, the dialog displays normally.

That's one serious bug, but at least it's easy to work around once you know.
