setting xhost rules at boot...

[yurtesen]

I am able to set xhost at boot in Fedora by editing /etc/gdm/Init/Default and for example add:

/usr/bin/xhost +local:

How can similar be done in Ubuntu? I want that the

/usr/bin/xhost +local:

command is executed when the system is sitting at login prompt.

Do you want it executed when the computer turns on (before showing the login screen) or after you have logged in?

To execute a command after you have logged in, add the command to .profile in your home folder (this will apply only to you).

To execute a command when you or anyone else logs in, add the command to /etc/profile.

To execute a command before anyone logs in, add the command to either /etc/rc.local or /etc/gdm/Init/Default (I don't know the difference between the two, so I don't know which one is preferable).

Thank you for the answer, This is the correct answer if ubuntu was using GDM (the Init/Default one). If I put it to /etc/rc.local, I believe it wont work since only the user who starts GDM would have right to change xhost setting.

However, since Ubuntu is using Lightdm at this point. I was looking for something which would work with lightdm. For now, I could solve the issue by giving shell to lightdm, setting DISPLAY=:0 in shell rc file and running su - lightdm -c xhost +local: from the rc.local. This is not quote elegant...
