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

• - sudo dpkg-reconfigure gdm3 followed by sudo service gdm3 restart
• - add nomodeset to GRUB_CMDLINE_LINUX_DEFAULT. Tried rebooting and still got the same blank screen.

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

I tried purging and reinstalling the drivers as per this answer - The output for some of the commonly requested commands across the forum in similar scenarios have been highlighted

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:

However, this looks like a hardware failure. Take a look at and to test your GPU memory.
