[solved] changed owner of /usr /etc /var folders ..

Hello There !

I messed up, as being the root user,
did a

chown -R root /usr /var /etc

I'm using KDE 4.2, and I bet I messed up with the system.

How can I recover this ?

I cannot start up kde from KDM, just dont know how can I make it work. I reinstalled the whole kde packages..

Thanks in advance.

edit: solved it by installing and turning on the  "consolekit" daemon: see this topic http://bbs.archlinux.org/viewtopic.php?id=62554

Re: [solved] changed owner of /usr /etc /var folders ..

Are you having any specific problems? I think your system probably should still work. You could just do

chown -R root:root /usr

if you want. Most of the directories in /usr are owned root:root on my system, and I haven't changed anything there from the default. If some of yours had different owners or groups, you can just change them back manually afterward.

Re: [solved] changed owner of /usr /etc /var folders ..

After rebooting, I cannot login to KDE (kdm is just restarting everytime i press the enter to login)

I'm using framebuffer now.
the mpd its still working fine, drivers are fine too (as the kdm appeared).

It seems that probably chowned /etc and /var too..

the command "startx" output is

Fatal server error:
xf860OpenConsole: Cannot Open Virtual Console 7 (Permission denied)

Xorg.0.log is fine, but the "permission errors"

That's interesting, all my policykit files are owned either by root:root or root:<user>, with the exception of /usr/lib/Policykit/polkit-set-default-helper, which is policykit:root. So maybe changing either to what byte listed or to root:root or root:<user> for those files would work.

If not, maybe reinstalling xorg-server would set the right permissions again.

Re: [solved] changed owner of /usr /etc /var folders ..

I reinstalled the xorg-server (and all of it's dependencies).

chowned' back some folders (above mentioned).

I still have to pkill the kdm and running the "startx" command.

btw:
