I installed Ubuntu 16.04 on my brand new hardware about a month ago (Intel I7 6700k, Asus Pro Gaming mini ITX motherboard and Nvidia GTX950 graphics card). Things have been going mostly well, however The pic repeatedly comes up with a 16.04 internal error, try restarting your computer
. When I look at the details it talks about compiz has crashed and Nvidia drivers. Firefox also repeatedly crashes, but everything else to date has worked perfectly.
So this evening I tried to correct the problem by upgrading the driver. I looked in the Software and Updates section, and it said it was using the reccommended driver (Nvidia 3.61.42) however when I looked online, a newer driver was available. I followed instructions posted on a forum page here, doing the install using apt-get
in a terminal window. BANG. Now I cannot log in at all!! The machine takes me to a guest login, which I have never used, and insists on a password I don't have (including leaving it blank). There is no option to use my standard username/login.
I am able to get to a terminal window (Ctrl + Alt + F3, or similar combination) but it wants a login and user name that does not exist. I know, I have read all over the place how this is the login you establish when you first install Ubuntu, well I can tell you that my standard login DOES NOT WORK! I have been logging in without incident for a month, but now using this same login, I can't get in, and I don't have a guest login either (as stated, never ever used)
So short of re-installing and spending untold hours re-configuring software etc. what do I do?
I have also tried the grub login as well. I can get into the GRUB menu, select a version with RECOVER. But when I select to use a low res graphics option, it just locks up. And the drive, though I can access it through the root option in GRUB appears to be read only, so I can't run something like DCONF reset as suggested here on the web. It just tells me everything is read only!
Frustrated and out of time this evening. Hope somebody has some answers.

Graham
