I'm a linux beginer and just got GNURoot Debian in my tablet. There are two commands necessary to make it run which is
export DISPLAY=:0 PULSE_SERVER=tcp:127.0.0.1:4712
Then the guide recommends putting them in a shell script to easily restart lxde and that's where I'm lost. Found some guides on how to create such type of file but none seem to have baby steps and none of my attempts have worked.
