I have a desktop PC with Ubuntu 20.04 + KDE. Yesterday my program gets stopped due to a no space left on device
error. I deleted some files and then found the freed space is soon occupied again. Through iotop
I found that plasmashell
is writing to the disk at ~19MB/s, so I killed the process. I have two questions:
What does plasmashell do? It seems to be related to the plasma desktop environment, but I wonder whether writing at 19MB/s until the disk is full is a bug, or do I need to worry about a virus?
Where does it write to? After killing the process the available disk space did not grow, which means whatever it has written to disk is still there. I'd prefer not to do a reboot because it is a remote machine (someone needs to be on site to log into the internet after the reboot).
.xsession-errors
which takes up 126GB. Seems to be a bug (unfavorable feature?) that has been reported 10 years ago: https://askubuntu.com/q/93718/1053356. – trisct Sep 15 '23 at 04:52.xsession-errors
file. Useless
to page through the errors. You'll see that one set of error messages repeats and repeats and repeats. Fix that error. Then, log out of your graphical session (to ensure the file is closed), log into a text session (Ctrl-Alt-F#, where # is 1 to 4) and finallydf -m .;rm ~/.xsession-errors;df -m .
