so bugbuntu 14.04 hit me again. I upgraded my graphicscard so i thought it would be a good idea to install new drivers. I changed from a HD 5850 to a R9 280X. I took a quick look at the graphicsdriver before installing the new one and it said something along the lines of "xorg blabla (open source)" under additional drivers. So i downloaded the new driver, ran
sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev* and installed the new driver with its installer and rebooted.
Upon reboot i got the low graphics mode error, tried reloading old config, didn't work. (The menu also severly bugged out, i always got returned to the dialog with "load old" and "reload current" with no message at all). running in low-graphics mode just caused ubuntu to hang indefinitely, same for going to terminal from there. BTW: pressing ctrl+alt+f1 there also caused it to hang.
So after some googling i tried the recovery mode,
failsafex just led to the situation described in the paragraph before.
root atleast brought me to console, but started with some error not being able to load /bash/XYZ and i couldn't use
apt-get there because it always errored out saying something was missing.
So, any suggestion on how to fix this mess is highly appreciated :)
