[SOLVED] Run as su

ceh383 · 05-26-2012, 09:58 AM

When I try to run thunar as su I get the following error...

Code:

bash-4.1$ su
Password: 
bash-4.1# thunar
No protocol specified
No protocol specified
No protocol specified
No protocol specified
Thunar: Cannot open display: 
bash-4.1#

Being a poor typist, this is my preferred way to navigate to files for editing.
The computer is a Dell XPS l702x with dual video (integrated intel and discrete nvidia) running BumbleBee 3.0

I can enter

Code:

export XAUTHORITY=~/.Xauthority

as a user then su and it works. Is there a config file that can be edited so this can be skipped?

And I know running as root is not the best way to go about it, but, It's the way I like to do it...

Usually you have a tool comming with your wm... For kde it's "kdesu"... It launches a command as root, but setup display so it can use the "user space" xserver (it's a simplification).

You can use kdesu even with other wm comming with slackware, of course, if you've done a full install...

Code:

 bash-4.1$ kdesu thunar &>/dev/null &

(You can ommit the redirection and the background parts if you want some verbose/debug...)

EDIT: I haven't tried, but you might even be able to do something like:

Code:

 bash-4.1$ kdesu terminal &>/dev/null &

... and launch a 'root' terminal, being able to launch any graphical tool from root... WARNING: I haven't tested that, it needs to be confirmed.

Bests.

You can just add a xhost line like the following:

Code:

xhost local:root &>/dev/null

in your ~/.bashrc to allow root opening X windows.

That worked, thank you...

Just a word of caution on this one. The "local:" family option on xhost ignores the username so the above would open the xserver up to any local user, not just root. If you're running a desktop machine it's probably not a big deal, but if you want to keep things tighter, you can use the following instead.

Code:

xhost +si:localuser:root

Did you try

Code:

su -

instead of "su"?

Thanks for the advice!
