After not using Linux for a while I reinstalled to get access to Linux version of games (only just found out that Descent 3 now has an a recently released enhanced native Linux version). However the installation has failed 3 times now. First with Ubuntu 20.10 when I updated to latest AMD provided amdgpu drivers. System then fails to boot. Then I installed 20.04 (whatever the previous release was) and amdgpu driver 20.50 still fails to install even though that was the recommended version of Ubuntu in driver release notes. This could have been due to a wrong kernel version ... but then why did AMD install script not warn me ?
So then I read about Mate having hidpi (4K) support and was expecting my display to scale up properly yet it never did. It's a secondary display via HDMI. While setting the primary display the Mate gui froze even though mouse pointer was still moving.
What on earth is going on here ? Please help if you can. I'm usually pretty good with Linux and have never had multiple failed installations like this. I suspect that ...
The AMD RX 590 is the problem - Sapphire NITRO+ RX 590 8G G5 SE. How do I get proper drivers and the full Radeon control panel ?
I installed to a secondary partition and put the grub bootloader on the same partition (not at the top of primary) as I can boot straight to that partition from UEFI bios and did not want the Windows bootloader replaced.
I notice the installer has some UEFI driver stuff like asking for a password. Yet I was never asked for this password. Could this be a problem ? Yet I can boot into Mate.
How do I get Mate to scale up everything on my 4K display (3840x2160 ?).
Any help appreciated !
