my system: Lubuntu 20.04.4 LTS, 64 bit
I wonder if anyone could help me with a certain “problem”.
Yesterday evening (I just wanted to end my session) my system suddenly went partially unresponsive.
What I had done just before it happened was this:
I unmounted my USB-Sticks from within PCManFM-Qt and then closed the file-manager.
I seemed to have forgotten something, so I opened up thunar (which is also installed on my system). Yet this took an unusually long time and I couldn´t close it anymore.
Plus: every popup-window I opened by clicking on the respective icon in the taskbar couldn´t be closed either.
This is the unresponsive-part.
But I could change into a virtual terminal with
CTRL+ALT+3. From there I could have triggered some appropriate action - had I known what to do.
top -i didn´t show any process with unusually high cpu consumption. So nothing there.
I would have liked to restart either (or all) of those processes:
pcmanfm-qt … in the hope to get a responsive system back.
Could you tell me what the correct command for doing this might be
Many thanks in advance …
… and many greetings from Rosika
In the end I issued the REISUB-sequence (holding ALT+Print) and after the reboot everything worked fine again.
