I have no damaged packages. Any help would be appreciated.

I do not have MATE, but generally speaking some places to check are the System Reports app and /var/log/syslog.

I do not have MATE, but generally speaking some places to check are the System Reports app and /var/log/syslog.

Sorry, but that sounds Chinese to me. I purposely tried to adjust the keyboard. Then I searched today's syslog for the word keyboard, but nowhere did I find it says failure. The system report claims no problems.

I purposely tried to adjust the keyboard.

Because I'm not familiar with the MATE apps, I'm not sure where that might be recorded. However, a window crashing seemed like a big enough issue that I would have expected it to be recorded somewhere.

We'll have to wait for someone more familiar with MATE to help.

[diabolicbg]

I did a clean install of LM 20.3 MATE and it crashes the settings again and I can't change the keys to change the keyboard layout - En/Bg. Currently I can only change the two keyboards using the mouse.

Can someone write me a command via terminal to change keys to Alt+Shift keys And to turn on the LED when changing the arrangement ?
Thanks!

In two days, I reinstall LM 20.3 twice on a clean install and check the keyboard right after the installation is finished - the settings crash.
I found this in the system report a while ago. Please someone who understands give advice what to do.
Today I found that this problem exists on all my 3 computers with LM 20.3. With 20.2 it did not exist. Now my other two computers are switching because they were set up at 20.2 and then upgraded. But the main one - my desktop cannot change the language from the keyboard.

I'll run an experiment. I'll remove the Bulgarian keyboard and install a German one to see if the settings break again. Maybe there is only a problem with the Bulgarian language pack?

EDIT: The experiment gave the same result again. Apparently the reason is not in the language pack. This is the system report after the experiment:

I'll run an experiment. I'll remove the Bulgarian keyboard and install a German one to see if the settings break again. Maybe there is only a problem with the Bulgarian language pack?

EDIT: The experiment gave the same result again. Apparently the reason is not in the language pack. This is the system report after the experiment:

I found the following bug report It is not possible to assign keyboard shortcuts to switch keyboard layouts when using the Ukrainian interface language #55 . It sounds like it might be a similar issue? If I am understanding it correctly, I think there is a workaround described. However, because I do not have a MATE install, I could be wrong. Perhaps the discussion in that topic might help.

Thanks for the assistance, but this is all very complicated and confusing for me - I understand nothing of these codes and don't know how to adapt them to my case.
I need a solution of sorts:
1. Do this.
2 Do that... etc.

Hopefully, someone with MATE can come to the topic and help.

I don't know if it's just MATE. You need a programmer for that.

There is a saying in Bulgaria: "Help yourself so that God will help you!"
I thought for a few days how to cheat the system and finally I figured it out. I changed the interface language from Bulgarian to English. The settings stopped crashing. I made the necessary adjustments and then put the Bulgarian interface back on the system. Now everything works perfectly if you don't touch the settings again.

Many thanks SMG for the good direction with the Ukrainian translation!

Apparently, the problem lies in the Bulgarian translation of version 20.3. I don't know if someone is sending information from the forum, but please admins to send this information to the Bulgarian translator, so that the error is not repeated in the next version!

mate-keyboard-properties is part of mate-control-center and is maintained by the MATE Desktop project: https://github.com/mate-desktop/mate-co ... ter/issues. I didn't spot an issue there that looks related to what you describe. I was also not able to reproduce your issue on Linux Mint 20.3 MATE by changing interface language to Bulgarian; something else must play a part in this.

If you want to troubleshoot this further and maybe help identify a bug in the MATE Control Center for its developers, I would suggest 3 things:

1. See if you change the interface language back now, you can still reproduce the issue.
2. If so then try the following: create a new user account, log out and log in to the new user account and (assuming the interface language is already correctly set for crashing) see if the issue is also present on a new user account. If not then it may still be a bug but one related to user preferences somehow.
3. And finally I would suggest to then make a bug report in the above project, and include debug output with debug info enabled (it's not in your output above). Unfortunately Linux Mint 20.3 is based on Ubuntu 20.04 LTS and debugging on that is a bit more involved because you have to manually install debug info packages. On upcoming Linux Mint 21 it will be trivially easy to get debug info by simply installing the debuginfod package. Anyway... I'll detail it for Linux Mint 20.3 below.

The steps to get debug output with debug info enabled are as follows. With this developers (and maybe we here) will have more information to go on, even if we can't reproduce the issue ourselves we can see where in the code things happen.

1. Open Software Sources and enable debug symbols on the official repositories tab. Refresh the repository cache as prompted.
2. Then run apt install debian-goodies on the terminal to install a necessary package for the next step.
3. Then run find-dbgsym-packages /usr/bin/mate-keyboard-properties 2>/dev/null to find all needed debug symbol packages. This command will take some long minutes complete. Let it run. Once it's done it will print a list of all the debug symbol packages you need.
4. Then run apt install PKGLIST where you replace PKGLIST with the list from the previous step, to install all those debug symbol packages.
5. After all are installed start mate-keyboard-properties from the terminal as such:
   gdb -q -ex 'set logging on' -ex 'set pagination off' -ex 'thread apply all backtrace' -ex 'run' mate-keyboard-properties
6. The program will probably load slower and it may look like it's not doing anything for a bit. Assuming it will still crash when you do what causes that, you will see that on the terminal and have debug output here. Then type "quit" on the (gdb) prompt and press enter key to close gdb. It may ask if it is okay to kill the running program, that's okay.
7. You will now have a gdb.txt file with the backtrace with debug symbols. Attach that here or on the issue you create on the GitHub.

1. When returning to the Bulgarian interface, the problem resumed - the settings crashed.
2. The same happened with a new user.
3. In the next few days I will be very busy, but I hope to have time soon and be able to do the necessary bug report.

Regards,
Ivo
