 |
|
If I want to launch a program from the terminal, like qtella or the config program for imwheel I get this error :
| Code: | Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
Could not open display, check shell DISPLAY variable, and export or setenv it!
|
Mandrake didn't prepare me for this, how can I solve it without having to wade through any more man pages at 1 AM? I've been doing that all day and honestly don't feel like seeing another one... |

Only the user who logged in is allowed to use X (by default). If you have changed users while logged into X then the new user will get an error message like that when trying to launch an X application.
There are two ways around this that I know of (I think there are probably others as well). If I am logged in as juser and I want to run an X application as root then I just | Code: | | sudo X-application & |
You need the sudo package installed and configured to be able to do this. The other way is to issue as the original logged in user. This can be dangerous because it allows anyone access to your X-server even from remote machines so only do this if you are either not connected to the net or you are behind a firewall.
