I've done an upgrade from 12.04 to 12.10 on a PC with an i7 processor, an nvidia GT630 card video card and an Intuos 2 tablet. Everything went smoothly until I tried to also upgrade the nvidia drivers using the additional drivers tab in the Software Sources application.
Now the tablet is recognized (it shows up in the output from lsusb and xsetwacom --list devices) but neither the Wacom mouse or pen controls the cursor. By plugging in a USB mouse I do get a working mouse. The strangest part is that occasionally the tablet works but I can't find any pattern to when this happens. I've tried all the different nvidia drivers, but the problem is the same.
Possibly coincidently or they may have been there before and I didn't notice them, I now get some messages on shutdown that I don't know the meaning of:
Rather than invoking init scripts through /etc/init.d use the service(8) utility, e.g. service S35 networking stop initctl : unknown job S35networking
Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the stop(8) utility, e.g., stop S35networking
Is there a way to repair my installation or should I just do a fresh install of 12.10?
