Hi,
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.
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:
/usr/lib/xorg/Xorg
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.
Given that nvidia 450 is still in beta/first stable it will not have been packaged yet formally for 20.04. It will be eventually after a bit of time when it has gone through the stable release processes.
In the interim … since its beta/first stable, suggest tackle this on the nvidia forums to allow nvidia devs visibility of beta/first stable issues such as this.
I followed your link and installed and installed CUDA 10.2. After installation when I try to compile any sample code, it gives error “unsupported GNU version! gcc versions later than 8 are not supported”
So, CUDA 11.0 is the only option but CUDA 11.0 doesn’t work on budgie desktop.
I just installed NVIDIA CUDA 11.1 and the latest drivers by running these commands on a freshly installed Ubuntu Budgie 20.04 today, you can save them to a .sh file and run it in the Terminal and all you need to do afterwards is a reboot.:
