There may be many reasons for a computer not working after installing the driver via DoFlicky. I wrote to you to check the capabilities of eopkg sr nvidia-
. Currently :
nvidia-glx-driver-current - 560.35.03
nvidia-beta-driver-current - 565.57.01
nvidia-developer-driver-current - 550.40.80
nvidia-470-glx-driver-current - 470.256.02
You need to test. Just e.g. sudo eopkg it nvidia-470-glx-driver-current
. If you have a black screen, go to TTY and uninstall this package, and after reboot it should be fine.
To play, you also need to install the 32-bit version of the driver.
