Hello! I can’t seem to get the lightdm desktop after installing Cuda 10.2 with NVIDIA’s proprietary driver (440.33.01). I switched to lightdm from gdm, trying to circumvent this problem. I am currently able to see a GUI for the login screen, but after typing in the password, I only see a (still move-able) mouse arrow and the Bionic Beaver splash screen. I am currently logging in through ssh.
After consulting the forums, I found someone with a similar problem (https://devtalk.nvidia.com/default/topic/1054962/linux/nvidia-quadro-p1000-repo-nvidia-driver-430-not-running/post/5347818/#). I tried replicating the solution on my machine, but didn’t resolve the problem.
I am running Ubuntu 18.04 LTS. I installed CUDA via network deb method (https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1804&target_type=debnetwork) I have not disabled Wayland Server. I have blacklisted nouveau drivers.
I added the following to my bashrc file as instructed in the documentation:
export PATH=/usr/local/cuda-10.2/bin:/usr/local/cuda-10.2/NsightCompute-2019.1${PATH:+:${PATH}}
This is what nvidia-smi shows me:

Anyone else facing similar issues with deb[network] installation and workstation GPUs?
