I just installed Kubuntu 15.04 and everything were fine.. till I installed proprietary nvidia driver. After restarting the computer I can't login, because there's only black screen. However, when I choose grub recovery mode and then resume from the recovery menu system boots and proprietary nvidia driver works. It just doesn't work on normal boot. Nouveau works, though. Any suggestions?
I'm running Fedora 18 x86_64 on a system with a Nvidia GeForce 8400 GS videocard and the proprietary driver (xorg-x11-drv-nvidia-304.64-3.fc18.x86_64).
Sometimes, at startup, the Gnome Display Manager (GDM) login screen does not appear: the screen remains black and only the mouse cursor is visible; nothing else happens and I'm forced to reboot the system.
This issue has been occurring since I
