I was trying to set my GUI working on autorun boot through several methods (system, LXDE etc) but I think I screwed it up as none of them worked really. I must have mixed some commands up.
Right now, the terminal on my RPi runs on root (root@raspberrypi) as LXTerminal but I cannot change the content of my files (therefore I cannot make any backup via USB), use Web Browser (Chromium won't start, backup online not possible, but Wifi connection works) and other things (I don't even know about) which are not permitted. I have tried working with permissions but there is no effect whatsoever.
Can anybody help me how to set my RPi back to where it was before? (pi@raspberrypi)? Sorry for possible question duplication, being still a beginner with RPi, I might not even know what the appropriate keywords helping me to solve this are.
Thanks for any help.
