Permission mix-up on Mint

So recently I accidentally started changing all the permissions in root to my unprivileged account :(.
It happened because I was switching between users and shells and the directory changed to / without me noticing.
Luckily I had -c enabled so I realised there was something wrong quite quickly(just after the home dir).
I then ran chown root:root -R (all files owned by me in /)
Now I'm having problems with xscreensaver and su'ing reurns failed auth. I can still use sudo though.
Is there any maybe a list of permissions somewhere?
I'm running the latest Mint XFCE.

Well , since you recursively chowned everything, you also have chowned everything in your home . . . .Dochown -R yourUsername:yourUsername /home/yourUsernameto get your stuff back to your ownership

@Serg The problem is that most of the root filesystem was owned by me instead of root. I was attempting to dochown -R yourUsername:yourUsername ./but I was in / not ~

Oh, I see. Changing ownership of everything on the filesystem back to root user will be the easiest next to reinstalling. But there are many direcotries in files , such as /etc/shadow or /etc/mtab.fuselock that have different group ownership, so if you chown everything to root recursivelly you still have to go back and fix many other files.

This is pretty much an "+++ Out of Cheese Error. Redo From Start. +++" situation.
Lots of files down in the guts run as different users/groups and while most things can live as "root:root" if this is going to be a long running system you're better off backing up /home and repaving.
Alternatively find another computer, install virtual box, install mint, and then run:
find ./ | xargs ls -lth | awk ' print $1"t"$3":"$4" "$NF ' > /var/tmp/perms.
You should then be able to copy perms over to your mint computer, and write a script that reads that file and sets the right user/group ownership.
Actually, that would be a good penance as well as a useful technical exercise. :)

https://serverfault.com/a/117149/191095
getfacl -R / > /root/perms.acl
setfacl --restore=/root/perms.acl
It works perfectly. Now my xscreensaver and logging in as root work again :-)
