Hi again @Chaos5462; I see (from clicking username at upper left, 'View Public Profile')
that you were on LQ today, so I'll post a bit more (rather than my usual editing if unvisited)
(I just learned a lot here
, reading ch.2, in "Linux Bible" old 8th ed. Book)
I'd suggest this search: (including your distro, DE/WM might narrow, or otoh, exclude relevent general, results)
Linux System Settings missing|gone|lost ( | is 'OR' here, and might be done automagically by search engine)
https://www.google.com/search?q=linu...27t+open%7Crun
There seems to be lots of possible reasons, so that web-research should provide things to check,
to collect more problem data to post. (Other, more GUI-experienced, LQ'ers advice welcome here)
And, as I mentioned prior, it will likely lead to more specfic keywords, to narrow search & config info checks.
Let us know what you find, esp. to help future searches (with this problem)!!!
p.s. Additional (tho more complex) idea, to see precisely why it exits,
strace [ -f -o mystrc] 'it' from CLI; to find its cli pgm name:
