Hi Mike,

the file permissions only need to be fixed for the next login.
During startup, the xauth command needs the selinux file permissions
of unconfined_u:object_r:xauth_home_t:s0 or of unconfined_u:object_r:user_home_t:s0 to the .Xauthority file,
so that it can overwrite the file with the new Xauthority Information.
After that, everything works fine for the session.
At least for my test, where I did login and opened a terminal window.
Maybe I should try opening some more kde and gnome applications.
On my system, it is ok, when the permissions will be fixed at logout time.

Hi Mike,

what about the following solution / proposal for the x2goruncommand script:

# run logout scripts

FIX_XAUTH=`ls -Z $HOME/.Xauthority | egrep default_t`
if test -n $FIX_AUTH
  /usr/bin/chcon unconfined_u:object_r:xauth_home_t:s0 $HOME/.Xauthority

test -r /etc/x2go/x2go_logout && . /etc/x2go/x2go_logout


this fixes the selinux file permission in case, it it set to system_u:object_r:default_t:s0
It works on my system.



The position where you propose adding the fix does not seem right to me. As the file permissions will stay "wrong" for the duration of the session and will only be corrected after the session has ended.

Do I understand it correctly, that the file permissions need adaptions directly after session startup (i.e. after launching the session (destop) command)?
