I finally gave up my Nvidia 2070 Super and rejoined Team red with a 9070 XT. And it’s like this is the way everything was always meant to be.
HDR works without breaking font rendering. Sleep states just work. No more random border flickering in fullscreen or borderless windows. And the fans never even spin up.
I did have to unwind a couple Nvidia workarounds to swap over successfully (like /etc/environment needed cleaning up for sddm-greeter-qt to not core dump).
No ragrets.
No regerts.
Team red 4lyfe (again).
Until I saw this, I assumed it must be a problem with newer Nvidia cards because I almost never had a problem with my ancient GTS450 on Mint and LMDE.
And that “almost” is because of the one time something got added to the kernel that didn’t play nice with the OEM driver. Later kernels didn’t have the same problem.
All that said, I’m team AMD again and am likely to stay that way. The old computer was built during a very brief window about 15 years ago where it wasn’t uncool to buy Intel CPUs and NVidia graphics and, I assume, AMD were having problems.
The PC before that was AMD/ATI, hence “again” now.
