I have a desktop with GeForce RTX 2080 Ti.

After Ubuntu 20.04 Installation it loads straight onto a blank screen with a blinking cursor. I get a terminal on the system using Ctrl + Alt + F1.

I first tried all the suggestions mentioned below

I read in some forums that the graphics card maybe the root cause of the issue. So I tried checking the compatible versions on NVidia's website as well as tried running ubuntu-drivers devices

== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
modalias : pci:v000010DEd00001E04sv000010DEsd000012AEbc03sc00i00
vendor   : NVIDIA Corporation
model    : TU102 [GeForce RTX 2080 Ti]
driver   : nvidia-driver-465 - third-party non-free
driver   : nvidia-driver-418-server - distro non-free
driver   : nvidia-driver-450-server - distro non-free
driver   : nvidia-driver-460-server - distro non-free
driver   : nvidia-driver-460 - third-party non-free recommended
driver   : xserver-xorg-video-nouveau - distro free builtin

I went with nvidia-driver-460. Tried rebooting after that and still booted up into the same blank screen. I tried running nvidia-smi and then something happened to the display. It showed multiple purple glitches across the screen and returned No devices were found

enter image description here

I tried purging and reinstalling the drivers as per this answer - https://askubuntu.com/a/1129890 The output for some of the commonly requested commands across the forum in similar scenarios have been highlighted

  • Did you try ubuntu-drivers install? Try also classic dpkg --configure -a; apt install -f, check also logs with journalctl -p err -k -b0 -xe Jul 16 at 19:27
  • Well if you can get a terminal up then someone in the community should be able to help. You can type mokutil --sb-state to confirm is fast boot is switched off (a common problem) and let us know. After a clean boot and then opening a terminal try sudo systemctl set-default graphical.target this works for me after ugrades but does not fix "human errors". Jul 18 at 7:08
  • What CPU are you running, and what options do you have set on boot. Post the output of cat /proc/cmdline. If you have an AMD processor, then you may need mem_encrypt=off in your boot options.

Try adding pcie_aspm=off and rcutree.rcu_idle_gp_delay=1 to kernel cmdline.

You could also try installing the latest drivers from the Nvidia website. I know this isn't ideal, but it might be an informative test: https://www.nvidia.com/en-us/drivers/unix/

However, this looks like a hardware failure. Take a look at https://github.com/wilicc/gpu-burn and https://github.com/ComputationalRadiationPhysics/cuda_memtest to test your GPU memory.
