Luis Chamberlain sent out the modules changes today for the Linux 6.6 merge window. Most notable with the modules update is a change that better builds up the defenses against NVIDIA’s proprietary kernel driver from using GPL-only symbols. Or in other words, bits that only true open-source drivers should be utilizing and not proprietary kernel drivers like NVIDIA’s default Linux driver in respecting the original kernel code author’s intent.
Back in 2020 when the original defense was added, NVIDIA recommended avoiding the Linux 5.9 for the time being. They ended up having a supported driver several weeks later. It will be interesting to see this time how long Linux 6.6+ thwarts their kernel driver.
I have an RDNA3 card (upgraded from a 1080) and am running a multi-boot triple-head setup with mixed refresh rates (60, 144).
Pros: most things work and work well. Installation of the physical card went without a hitch and it was relatively simple to install the drivers. No issues with web video, streaming, video encoding, or standard use.
Cons: the drivers are still lacking significant features - I am still unable to reliably control fan curves/speeds, clock speeds, etc. FreeSync is unusable as well. I have also been experiencing regular crashes on certain games (BG3, Apex Legends, etc.) and support has been nonexistent, despite similar complaints from other users. When the card does crash, it usually results in a ring timeout and an accompanied total session crash. AMD does not seem to be responsive to these issues in either their official forum or any other space where people are lodging complaints.
The hardware seems fine; the drivers are the main issue. If I had to do it over again, I’d hold my nose and buy NVIDIA.
EDIT: regarding the cursor issue, I’ve had to switch to a software cursor on Linux. The hardware cursor wasn’t showing up at all.
