hi, i have updated recently.
since, I have restarted, I have a major problem.
everything work fine, I can use the terminal, even install software as root... as usual
but when I try to launch some less basic software as firefox or libreoffice, it fails. It is always a problem of reading or identification.
I have tried to run firefox as root to see. it works.
So it seems the user with its normal rights can't access some setting files, or something like that.
Do you have any ideas of what I could do?
