I recently purchased a Gigabyte “GT 710” single-port graphics card. I seem to have successfully download the driver from NVIDIA and installed it, but my displays don’t work properly. Specifically, when I connect the second display, it is black except for the mouse pointer, and the primary display shimmers. I am undecidd whether to simply uninstall the driver (how?) or wait for help in this forum.
It seems to be related to X. Before X loads, both displays work in text mode.
It’s Ubuntu 20.04 on a Dell Inspiron 3671 desktop
If you used the runfile installer, please uninstall it by running it again with --uninstall option. Afterwards, use “Software&Updates” to install the 470 driver from ubuntu repo.
I that doesn’t help, please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.
Thanks @generix . I successfully did the uninstall but I don’t know how to use Software and Updates to install 470. There are seven tabs and I don’t know which one to use. I always use apt-get or apt to install software. Please advise
“Additional Drivers”

@generix, that fixed it. I simply went to Additional Drivers, deselected X and selected the driver I had installed.
