I recently installed Ubuntu Budgie 20.04 on my laptop “Lenovo Ideapad 330 with NVidia Geforce MX150”. While installing NVidia CUDA Toolkit 11.0, I faced couple of issue which are reported here.
There are two ways to install nvidia drivers on Ubuntu Budgie:
- Install using “Additional Drivers” tool
- Install manually using .run file from Nvidia website
Problem with the first type is that software center shows “nvidia-driver-440”. If this driver is installed, it works absolutely fine but the problem with this driver is it supports CUDA 10.2 but CUDA 10.2 is not supported on ubuntu 20.04 as it requires gcc 7 and ubuntu 20.04 has gcc 9.3. So CUDA will not work with this driver. However CUDA 11.0 supports ubuntu 20.04 but it requires nvidia-driver-450 which is not present in ubuntu software center. So we need to install it manually by downloading it from NVidia website.
I downloaded cuda toolkit 11.0 which includes driver as well. I installed it following the installation instructions mentioned at following link:
After installation, I get blank screen, no display. I changed terminal using function keys and run nvidia-smi to check running processes. It shows /usr/lib/xorg/Xorg is running but no display.
But if you run nvidia-smi with previous installation (software center), it shows two processes:
- budgie-wm (or vm)
Anyone please help me resolving this issue and guide me how to run budgie-wm process on nvidia graphics.
Not to mentioned, this manual installation of NVidia CUDA 11.0 is working fine on ubuntu-desktop-20.04 but not on ubuntu budgie 20.04. Help me resolve this issue.
Thanks & Kind Regards,
