Relatively new to Linux. Lenovo T495 - AMD Ryzen™ 7 PRO 3700U - AMD Vega 10 graphics. Can't get video card working properly and can't install AMD pro drivers because of a 'failed for running kernel' warning.
Started shortly after the fresh install I went through the black screen at login and had to add 'nomodeset' in grub to get in. I then, based off another post here, I installed the mesa and vulkan drivers with this code:
sudo apt install mesa-vulkan-drivers
That solved the black screen problem, as I was able to remove 'nomodeset' and have a normal boot screen without issue. But I have all sorts of video issues. Playback in 'Library' is slow/glitchy on a 1080p video. And even when I close the video the audio keeps playing and I have to kill the process in Monitor. Playback of videos in VLC is smoother but the screen flashes black when I adjust volume or brightness with the F keys.
I then followed that post's advice for how to install the AMD Pro drivers, but at the end it says:
WARNING: amdgpu dkms failed for running kernel
So I uninstalled the amd pro drivers (otherwise I can't login cause it just keeps looping back to the login screen), and I followed instructions and installed ukuu and changed the kernel from 5.3.0 to 5.4.13 and then the latest kernel (I think it was 5.5 something), each time trying to install amd pro drivers and each time got the same 'failed for running kernel warning'.
I also tried the suggestion from somewhere to also manually install with this code
sudo apt install amdgpu-dkms libdrm-amdgpu-amdgpu1 libdrm-amdgpu1 libdrm2-amdgpu
I don't know what to do anymore. When I decided to quit Apple I expected some difficulties, but when I test drove things with an NVIDIA Macbook I could install the proprietary drivers in the AppCenter. With AMD it feels like we're just completely left to our own devices. Am I missing something? I'm 2 days into working on this. There has to be a way, but I'm not finding anything out there...
Really appreciate any help.
