[X2Go-Dev] [PATCH] xauth file location mismatch in x2gostartagent

[Milan Knížek]

Hello,

the /usr/bin/x2gostartagent script does not sufficiently specify the
location of $XAUTHORITY file for the xauth command, while the command
line for starting x2goagent refers to a specific location
$HOME/.Xauthority.

Usually, this works, because if nothing is specified on the command
line for xauth and the $XAUTHORITY variable is not defined, it falls
back to $HOME/.Xauthority.

Nonetheless, recent GDM versions set XAUTHORITY
to /var/run/gdm/auth-for-$USER-blabla/database.

As a result, when opening a shadow session as another
user, /usr/bin/x2gostartagent adds the cookie to $XAUTHORITY
(/var/run/gdm...) and then starts x2goagent -auth $HOME/.Xauthority,
which fails obviously.


The attached patch removes the -f $HOME/.Xauthority parameter from the
x2goagent command line to resolve the problem. It also removes a
redundant '-S' parameter (there is already $SESSION_TYPE there).

Can users of other distributions or display managers test if it does not
break something else? (It works on Arch Linux with GDM and Xfce.)

Regards,

Milan
