I'm using my phone right now because I completely lost access to my Z510 laptop running 14.04 (Trusty Tahr), I had no problem using my laptop, everything worked fine and I was really enjoying it for a while just before I had this temptation to install the videogame Dota 2 which runs on an independent client known as steam.
This is where the problem actually appears: software runs but asks that the user must install three packages, namely,
libgl1-mesa-dri:i386, libg1-mesa-glx:i386 and libc6
I checked synaptic for these packages, successfully found them and install them, they also automatically removed some other packages under the architecture amd64, I thought to myself that I have a 4th gen i7 CPU, so this kind of changing may be good for performance by what its name has to offer. After installing them (and removing others) I went to Nvidia settings tried to switch to my GF 740m graphic card, I encountered an error, so decided to reboot the machine and here I am, the purple frozen screen.
Can I do something about it? may I somehow acces to my stored data (some of them are pretty necessary)? Can I repair the OS using a live usb/dvd ubuntu image? what do you suggest? Thanks in advance
