I have a gazp8 that came with 13.04, so this is the first upgrade on this machine.
When I boot up I get a box that says " the system is running in low-graphics mode. your screen, graphics card, and input device settings could not be detected correctly. You'll need to configure these yourself." It then asks me what I would like to do: run in low graphics mode for just one session, reconfigure graphics, troubleshoot the error, or exit to console login. Run in low graphics mode and exit to console login go to a black screen with a blinking cursor in the corner. The other options do nothing useful either.
I have opened the console and updated the system76 driver, and made sure that the rest of the packages were up to date, and am at a loss as to what to do next.
I really needed my computer to work tonight, and am pretty disappointed about this, especially since I got an email saying that system76 machines were ready to go for 13.10.
