OK, the word useless was a bit rude, sorry. I just meant there are many articles that were not touched since years and need updating. Wrong links, old screenshots, new infos missing, like the above mentioned examples of the QT variable, since it has to now be added how to source the .profile because it is not sourced by default anymore. As i mentioned in this tutorial.
It just is a lot of work to make it correct again. I considered volunteering, but i just do not have the spare time for it, unfortunately.
You mean ~/.bash_profile instead of ~/.xinitrc @banjo banjo?
Not than it would not work that way too, but editing the small .bash_profile may be less intimidating for new users. At least on xfce that it, i am not sure if the other DEs use bash.
