I'm not very familiar with Ubuntu, hope to not bother you too much.
I had Ubuntu 12.04 LTS on my HP Pavillion dv7-2005eg, after not being able to fix the Intel/AMD hybrid graphics disaster in 12.10.
Everything went smooth until I gave in to the always popping up upgrade to 13.04 window...
Well since then, nothing is working. If I boot I get the 'running in low graphic mode' prompt and can only access tty1. Trying to install the drivers from there didn't work, flgrxinfo always tells me that 'error: unable to open display (null)' although it's installed, I don't even know how these things are connected.
My question is can I reinstall Ubuntu 12.04 from that terminal, it has internet connection. I tried to boot it from a USB drive created on MAC OS with unetbootin but it simply doesn't boot that even if I choose it from the BIOS boot list.
Would be real grateful, have been searching on-line but could not find anything like that, sorry if it's a double post.
Thanks in advance...
