For example, if I try to open a video with VLC, I can see it appear on the System monitor but it's quickly listed with red and disappears.

It could be RAM related. I have 4GB and it's shown as 70% used. But I have a 4GB swap file and it's not even 1/4 used.

I'm new to Linux.

EDIT: Terminal message

2023/06/05 17:30:51.401887 system_key.go:129: cannot determine nfs usage in generateSystemKey: cannot parse /etc/fstab: cannot parse check pass number: "1o"

  • HI. Try to open VLC using the terminal. - Open the terminal application - write there 'vlc' and press enter It will crash but will leave you some text that you can add to the question – aafirvida Jun 05 '23 at 20:14
  • @aafirvida I added the info to the main post – fede Jun 05 '23 at 20:34
  • @fede - if vlc was installed as snap - remove it and install it via apt. It should work then, (First thing I do on Ubuntu is to remove snap and all related packages) – kanehekili Jun 05 '23 at 23:33
  • @kanehekili +1 to your comment, I do the same. Snap does not work for me. – aafirvida Jun 06 '23 at 14:49

Looking for this same problem here

You can solve your vlc problem with:

sudo rm /var/cache/fontconfig/* 
rm ~/.cache/fontconfig/*
fc-cache -r
