From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

AMD GPUs are cursed for me (lemmy.world)

Each time I try AMD graphics, something is fucked for me. Back with fglrx, fglrx just sucked, so I used Nvidia. Then I had an AMD right around when they finally had opensource drivers, but it was still buggy as hell. So I went with Nvidia again (first a GTX 790, then a GTX 1060). In the meantime I had a new work notebook where I also went with an AMD APU, and had driver crashes for a long time when I was in video calls and it had to decode multiple streams. That thankfully stabilized with Linux 6.4.

Since sooo many people in the community swear by AMD, I thought "dammit, let's try it again for my new desktop" and got an 7800rx ... and I have to reboot ~5 times until I finally make it to a running xserver or wayland session. Apparently I am hit by this problem (at least I hope so). But that doesn't even read nice ... the fix seems to be to revert another fix for powermanagement. So I either have a mostly non-booting card or suboptimal power management.

I start to regret having chosen AMD .... again :-/ I seem to be cursed.

I have a similar story with an RX580, I replaced my GTX 1060 3GB for a 8GB RX 580 mostly because the 3GB of vram were an issue for BeamNG.

Now I can't record my 3 displays with the RX 580, it just fails when trying to do so, and 2 displays results in constant encoder overloads, something that the 1060 had issues at all, also my colors are off when recording and I have no idea why, it even happens when recording with the CPU:

Also kernel 6.6 broke the power reporting on all polaris GPUs, thankfully that was fixed recently in kernel 6.7.2, but holy shit it took like 6 months to fix that.

I probably shouldn't have read tests and forums, but simply searched for crashes and open bugs to get a feeling for what I am getting into. Then again I also read from people with very ugly problems with nvidia, so it's not a really good measure.

I really want AMD to be good; they offer more VRAM where nvidia always seems to cheap out in pretty suspicious ways. Then again nvidia seems to be more power efficient.

My time with nvidia on linux was 0 issues in performance or usability.

The only sort of issue that I had was that the GTX 1060 drew 20W at idle when using the 3 displays, this was a bug that nvidia fixed for the RTX 20 series and newer cards but never fixed for pascal lol.

But even on BeamNG, there was a period were the native linux version didn't work on mesa while it worked for nvidia, now to be fair with amd this was because the vulkan implementation of beamng is horrible and right now it does not work on either lol.

Polaris GPUs had very weak video encoders, I also had an RX 580 and had issues on Linux as well as Windows. To my knowledge the AMF encoders worked better for those, but I could never get them working with OBS

Oh I did try to use the AMF driver, my first attempt ended with i3 crashing upon startup. What was worse is that even after removing those drivers and putting mesa back it still crashed on startup, good thing I had a btrfs snapshot before messing with that.

My second attempt I was able to use the AMF on OBS, but it still failed to record the 3 displays.

My biggest issue right now is the issue with the colors, I don't care if I have to use the cpu to record at this point.
