Thanks for the links. Note that each of those links themselves contains links to the main problem reports at the bottom of the page. So you are experiencing bug 1771485, bug 1543192, bug 1771486 and bug 1771484 at least. As we know those bugs are often about login failures and black screen problems I think it is more useful to continue with those specific bugs instead of this one. Especially bug 1543192, which other Nvidia users are reporting. P.S. Some duplicate bug links don't work because the main bug is marked as Private. Just let us know which ones and we can make the public... ** This bug has been marked a duplicate of bug 1543192 Xorg crashed with SIGABRT in OsAbort() from AbortServer() from FatalError() from dix_main() ["no screens found"] -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1770238 Title: [nvidia] Logging in results in a black screen for many minutes after which the login screen reappears and I am able to login fine.
