Run Programs As Another User

You can always switch to another user by using sudo or sudo su, however you loose the capability of running graphical programs. To run graphical programs as another user follow the guide below.

Installing Required Packages

You need kdesudo installed (redhat/centos users will use kdesu). In a console type:

sudo apt-get install kdesudo

Running XTERM As Another User

By running xterm, you can then run graphical programs from the command line and using keyboard shortcuts can background them and run more if needed.

sudo kdesudo -u USERNAME -c "xterm -ls"
