Recently, after booting the window appears "System Problem Detected" - and I choose "Report problem". So how can I find out what actually is the problem? Otherwise everything works as expected. Xubuntu 18.04 on HP15 laptop.

I have the same on 19.04 Budgie. Started today for me. So it might be a bug. The popup does not help... no details or anything to go on – Rinzwind May 21 '19 at 16:48

Check for a .crash file in /var/crash – user535733 May 21 '19 at 17:18

OK, with the /var/crash file I know what may have caused it. I'm aware of the situation (dkms, non-kernel WiiFi module) and have a workaround. Thx. – Janos May 21 '19 at 18:00

The "System Problem Detected" popup usually means that a crash occured.
The apport application listens for crashes. When one occurs, it constructs a .crash file in /var/crash with plenty of details for bug triagers to understand how and why the crash occurred.
Look in /var/crash for the .crash file to learn the cause. It's an ordinary text file - you can open it in any text editor.

@Janos Hmmm. I find that I don't need to use sudo: `gedit /var/crash/filename.crash` opens the file in gedit properly in a stock 19.04 test system. Opens properly in Nautilus, too. – user535733 May 22 '19 at 15:17

U're probably right, I've already removed the file, but I remember that Thunar had a tiny "x" on the file icon, so I did sudo cat linux-headers-4.15.0-50-generic.0.crash | less - sorry, I could not make the formatting, tried ctr+k or sp sp sp sp – Janos May 23 '19 at 18:18

A simple `less /var/crash/filename.crash` should suffice for most folks. It should be user-readable. The developers *want* you to be able to read it. You can also pastebin the file for convenient browsing from a desktop. – user535733 May 23 '19 at 18:43
