I am reinstalling Kubuntu again now (second time today, joy!), and was wondering is there anything wrong with the following as a driver upgrade process;
Not enabling any of the resticted drivers under KDE.
Hitting ESC from GRUB and booting to a root prompt.
Pressing Ctrl ALT F3
Running the nvidia driver install.
Sudo reboot.
I was just wondering if this process might give me more luck. I seem to be having the API mis-match issues regardless of what i do when the 180.11 drivers were enabled within KDE.
EDIT: This seems to have worked for me, i now have the 185.14 version of the nvidia drivers loaded.
I would be interested to know from people what they think i was doing wrong before. (It seems from the nvforum that Ubuntu is bloody tricky to get new nvidia drivers working on sometimes).
