I've been unable to make my friend's PC graphics card work with Ubuntu 19.04, 19.10 and elementary OS 5.0 (18.04 based) since I first tried in April.
The card is a GTX 1660 and whenever I install NVIDIA 435 or 440 drivers (whether from the official repo, the ppa or using the .run from NVIDIA's website), I get a black screen, the monitor keeps shutting on and off (no signal) and I can only ssh into the machine. In the Windows partition 10 it works perfectly, and before I install the NVIDIA drivers in Ubuntu all I get is a very poor resolution like that in secure graphics mode.
Usually, the nvidia-smi command gives a driver error, but I've just formatted and fresh-installed again today to try for the thousandth time with the new 435 driver from the official repo (not the ppa), and at least I get a nvidia-smi response with everything seeming ok. But still, no signal. Any recommendations? Blacklist nouveau (I had already tried that before)?
It's been a lot of months waiting for better support for these quite new cards (or so I thought), and I'm starting to get desperate. The machine status now is:
- Fresh installed Ubuntu 19.10 which defaults to driver 435
- Updated everything and rebooted
- Black screen so can't even install openssh
Any idea?
Edit:
I've found that I can set the BIOS setting Initial display output to IGFX instead of PCIE 1 (it's a Gigabyte motherboard), plug the HDMI cable to the motherboard's video output instead of the Nvidia gpu one, and then I can get to the desktop.
Awkwardly for me, everything seems to indicate the NVIDIA GPU is in use (is that even possible connected to the integrated gpu?). Even the gears tests make the GPU usage jump to 100% in the NVIDIA settings app. Despite of this, if I instead boot Windows, the NVIDIA app says I'm not connected to an NVIDIA card.
