I've been using Ubuntu 12.04 installed via Wubi on my Windows 7 laptop for a couple of months now. Last weekend I installed Spotify and Pycharm (which required me to download a Java library) and since then I can't boot up.
When I try I get an error message saying 'The system is running in low graphics mode' and the screen freezes. Having googled it (on my phone) I found this thread that discusses it How to fix "The system is running in low-graphics mode" error? (it appears to be an issue with the graphics driver)
The second issue is when I follow the instructions in the answer above and try to boot via FailsafeX on the recovery menu I get as far as 'Loading extension glx' and the screen freezes again. Googling that problem led me here Loading extension GLX : screen freezes but it's not clear to me how I'm supposed to run commands when the FailsafeX process is failing?
I'm relatively new to Ubuntu/Linux and while everything I've worked on within my installation has been backed up, I'm loathed to have to uninstall the wubi installation and start again. Equally, I don't want to start trying things without understanding what I'm doing and potentially making it worse. Any help on this would be much appreciated!
