root with X access

Using Debian Squeeze and others older versions, the root cannot execute X programs from a x-console (like kde-konsole or gnome-terminal).

To allow this just edit your root's .baschrc and add this line

export XAUTHORITY=/home/$SOME_USER/.Xauthority

where  SOME_USER is replaced by a user with X access.

In Debian squeeze the jacksense in my laptop didn't work. Solution: I installed the latest Alsa driver. In Debian wheezy works fine.

My first post... I really like Linux

I like to use Linux a lot, and my favorite distro is Debian, most of my post of this blog will be my experience on my computers using Debian wheezy.
The idea is to write and share a diary based on the configuration problems that me and some friends have faced installing and configuring programs in Linux, and how to solve this issues.
