I have an ASUS laptop with Nvidia 950M GPU with optimus technology. Ubuntu mate 16.04 runs fine on it.
I installed Ubuntu Mate 18.04 beta 2. On first boot in the new system I did an upgrade and then installed the Nvidia drivers (390) using the “Additional Drivers” tool, then rebooted. After reboot I only see a black screen. It is not frozen or crashed, it just doesn’t display anything (I can tell since I hear the sounds and it responds to commands).
I also tried 4 different fresh installs of Ubuntu Mate and using Mate Tweak, I changed the Window Manager to each of the 4 options (Compiz, Marco - no compositor, Marco - software, Marco - GPU ) before installing the Nvidia drivers. I tried with and without automatic login on boot, since I thought the login screen might be the one causing problems. I tried kernel options: “nouveau.modeset=0” and “nomodeset”.
The result was the same.
This is not an issue in Ubuntu (Gnome). I also tried Kubuntu and Ubuntu-budgie, and on both this problem only affects the login screen. If I enable automatic login on boot, they work fine. (Mate doesn’t work even with auto login)
Do you have any suggestions what I can try next?
