I tried to reproduce this, but it seems this only happens on a real nvidia card.
If this happens for you, can you please do the following: - ensure that the nvidia driver is not installed, and jockey is not opened; best is probably to do that from a fresh install, but if you can reproduce it again after uninstalling the driver, that's fine - sudo killall jockey-backend # if that fails with "no such process", that's okay - start jockey, confirm that nvidia is displayed as available, but don't do anything yet - determine the PID of jockey-backend: ps aux|grep jockey-backend|grep -v grep |awk '{print $2}' - sudo strace -f -v -s 1024 -o /tmp/jockey.trace -p 12345 Replace 12345 with the pid you determined in the previous step - enable nvidia in jockey - confirm that it crashes - go back to the terminal with the strace, press Control-C, and attach /tmp/jockey.trace here.
