3.6 does not work in Linux Mint 20

• Jan 19, 2021 - 19:13

Opens fine, loads scores fine, but the menu is completely inactive and you cannot do anything. You can't even exit the program. (Clicking on the close-window "x" also does nothing.) Massive FAIL. This is still an alpha version, clearly.


Any chance that there is a model dialog open that your missing (such as the telemetry dialog on first run)? If so, try pressing Escape once after launching and see if that works out.

When you say it loads scores fine, what do you mean? You were able to go to File / Open and select a score, but upon loading it, then the menus became inactive? Was this a score created pre-3.6? If so, did you see a dialog asking if you wanted to update the fonts etc? If not, probably the dialog opened offscreen for some reason, and hitting Esc should close it. Otherwise, we'd need more information to understand the problem that appears unique to your particular system.

Ah, sorry. It successfully loads my previous session from version 3.2.3 (from the repo), so there are scores to see upon startup. The update-fonts dialog did pop up, and that window operated normally. But the main MuseScore window is inert. Using the keyboard (e.g., Alt-F for the Files menu) also did not work. It seems like MuseScore is functioning normally, from what little I can tell, except that the main window is failing to interact with mouse or keyboard.

I'm running Linux Mint 20.1, kernel 5.4.0-64-generic x86_64, Cinnamon 4.8.6. The AppImage file name is MuseScore-

When I try starting it from the command line in a terminal, it hangs on "restoring session". In the terminal appears the line "QWidget::insertAction: Attempt to insert null action". I don't know what that means, if anything. When I run it from the command line, the following gets added to /var/log/syslog:

Jan 20 12:11:10 hypatia dbus-daemon[23246]: [session uid=0 pid=23244] AppArmor D-Bus mediation is enabled
Jan 20 12:11:14 hypatia systemd[2564]: tmp-.mount_mscorees66NN.mount: Succeeded.
Jan 20 12:11:14 hypatia systemd[1]: tmp-.mount_mscorees66NN.mount: Succeeded.

which seems to indicate things are happy at that point. But when I double-click on the AppImage (and it successfully restores the previous session), this appears in /var/log/syslog:

Jan 20 12:12:17 hypatia systemd-resolved[1370]: Server returned error NXDOMAIN, mitigating potential DNS violation DVE-2018-0001, retrying transaction with reduced feature level UDP.

I don't know what else to try at this point.

Re clicking on a score: interesting. The toolbars are now almost fully functional, and I can edit successfully. However, anything eliciting a dropdown menu does not work, still. Also, cannot exit the program at all, other than to kill the process.

Re -F option: I get this error message:
/tmp/.mount_MuseSckuK7Ld/bin/mscore-portable: symbol lookup error: /tmp/.mount_MuseSckuK7Ld/bin/mscore-portable: undefined symbol: _ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEED1Ev, version Qt_5

If instead I use sudo,
sudo -E ./MuseScore-
we're back to the same behavior as clicking on a score.

If I do s straight sudo (no -E option) with -F, the whole window goes gray and nonresponsive as soon as I close the start center window.

If I do sudo -E with the factory reset flag -F, I get the grayed-out screen again as soon as I try to load a score.

Exactly the same happens after I downloaded and installed the latest version 3.6, other versions I have had no problems with. I have Mac OSX Catalina 10.15.7 and a high end Macbook Pro 16"

So Disappointing

To summarise I open the 3.6 musescore3, all the windows appear as normal, All the Musescore options on the Top Options menu are all greyed out. Clicking anything anywhere just give a Mac bing sound. Even the red close window button doesn't work. Only option is to CMD-OPTION-ESC and kill the app. Or locate the PID and kill -9 it from a terminal.
