What happens if you enable a 3rd party driver (like ATI) with Jockey, but after a reboot your graphics is broken and you can’t log in to revert?
Answer: Use the command line version of Jockey!
Here’s how you can revert any installed 3rd party driver using Jockey from the command line:
- At log in (perhaps with a broken X screen), switch to another terminal using the key combination:
- Log in as root
- Get a list of enabled drivers from Jockey:
- Disable the driver (such as the ATI driver):
- Once it has finished, reboot!
Ctrl + Alt + F2
When using Jockey, you should ensure that you have the latest updates applied, in particular the latest running kernel. This is because you might otherwise get a driver for a newer kernel, which might break your system upon reboot, or fail to activate.
You can also try using akmods with Jockey, which will build a new driver for you on reboot, if one does not exist for your running kernel (no matter what that is!).
