[Discuss] Linux Mint Cinnamon Home Permissions

[Jerry Feldman]

Most of these settings are stored in "hidden"  files in your home
directory.
An 'ls -al' will show you all your files, hidden or otherwise as well as
the permissions.
Once you determine that these files may have incorrect ownership, then:
'sudo chown -R <you>:<your group> .'
Should set everything back to the correct ownership.

-- Another test may be safer
1., become root using sudo ' sudo -s -H'
2. cd /tmp.
3. Check permissions and ownership of files in /tmp
4. reinstall the nvidia driver. Something like 'apt-get install
--reinstall nvidia'
After reinstalling, check the permissions and ownership in the /tmp
directory.
5. Restart X by logging out, and logging back in. Your home directory
should be untouched, and it any file permission has changed in /tmp,
then the nvidia package is suspect.
