Hi,
I have a 1070ti on Ubuntu 18.04.02 (5.0.7) with 418.56 drivers. It works fine but i can’t enable 30 bit color depth or HDR 10.
Display setup:
Main monitor: HDR 10 capable 144hz FreeSync2 1440p DisplayPort 1.4 (FreeSync works fine)
Secondary monitor: Not HDR 10 capable 60hz 4k HDMI 2.0
The problem is when i switch to 30 bit color depth both within NVIDIA settings or xorg.conf and restart, then i can’t interact with Ubuntu UI with mouse, my wallpaper is black and only the keyboard is working. It’s working fine on 24 bit color though.
My xorg.conf:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 418.56
