On Dell G3 15 with GeForce GTX 1050 Ti/PCIe/SSE2 I am connecting to an external (acer) monitor via HDMI. I do not have any image (the screen is black) sometimes is coverd in blue dots or blue lines.

I ensured that:

  • The HDMI cable is not damage
  • The monitor is working
  • I tried on several new monitors
  • I tried different refresh rates
  • I tried on xorg driver and several NVIDIA drivers
  • Switching to Wayland; Ubuntu 16.04 and 19.04
  • sudo ubuntu-drivers autoinstall

Xrandr outputs:

  • journalctl cat give more details over /var/log/syslog. Try using journalctl | grep -i nvidia Also with my new 4K monitor I couldn't get 60Hz to work and had to use cvt to generate frequency of 54Hz. – WinEunuuchs2Unix Jul 5 '19 at 10:43

Problem appears to lie within nvidia persistence daemon. Here's what my working system looks like from last boot (I suspend and resume many times a day instead of rebooting):

Jun 21 17:24:31 alien systemd[1]: Starting NVIDIA Persistence Daemon...
Jun 21 17:24:31 alien nvidia-persistenced[1102]: Verbose syslog connection opened
Jun 21 17:24:31 alien nvidia-persistenced[1102]: Now running with user ID 122 and group ID 131

Jun 21 17:24:31 alien nvidia-persistenced[1102]: device 0000:01:00.0 - registered
Jun 21 17:24:31 alien nvidia-persistenced[1102]: Local RPC service initialized
Jun 21 17:24:31 alien systemd[1]: Started NVIDIA Persistence Daemon.
Jun 21 17:24:32 alien kernel: nvidia-modeset: Allocated GPU:0 (GPU-30fab9bc-fe6f-ec05-e8e6-c151a1a96121) @ PCI:0000:01:00.0

I also had problems with nvidia-persistenced when I first setup my laptop and it took some googling to fix.
