![]() ![]() Turns out I had to enable the AHS repo (Advanced Hardware Support haha, for a ~10 year old card) - anyways, turns out I guess some drivers (amdgpu) or Mesa was outdated but AHS had newer ones, which worked without a hitch. Just had an issue with this and couldn't figure out why MX Linux was having issues but Manjaro wasn't (same hardware). There is a way to make the change permanent (and can be reversed, but test it via grub entry editing at least once first):įor me with an AMD HD 7770 this was enough to have AMDGPU working (a little before I retired it), without altering modprobe blacklists or anything That should be enough to test if amdgpu works for your card, and next time you boot it will have reverted to radeon on its own already, because the entry editing via grub is not stored for later This is an example of how editing the boot menu looks like (but with different edits): Radeon.cik_support=0 radeon.si_support=0 amdgpu.cik_support=1 amdgpu.si_support=1 amdgpu.dpm=1 amdgpu.dc=1 Just get to the boot menu, select the default boot entry, type "e" to edit the entry and type all the code below into the entry at the end: and maybe you should try another route to the same result first, via kernel boot parameters, since it is trivial to revert boot parameters to the original in case something goes wrong It should cause no permanent damage to the OS, but maybe having a liveboot usb will help make recovery easier (always good to have one around). These instructions involve blocking the radeon module with modprobe and I'm not sure how easy it would be to revert to the old config if it can't boot, freezes, goes to a black screen or falls to a terminal instead of GUI. Valve's proton requirements page now has a section with instructions for this because only amdgpu has support for Vulkan (which DXVK needs for proton support to DX10/DX11 games): As always, your milleage may vary (and for anyone else reading this, AMD R9 270X support is specifically horrible) The good news is that with recent versions of Mesa and the Kernel this should work quite fine for a lot of people (and easy to test and reverse if it doesn't), sometimes better (as in sometimes cooler and more stable, not just faster and with vulkan) than RADEON. You can boot linux with a few kernel flags to make it use AMDGPU (the new opensource driver, also included in Mesa but only used by default for GCN 1.2 and newer cards) instead.ĭisclaimer: AMDGPU support for GCN 1.0 cards is *experimental* and *can* run into issues. GCN 1.0 cards run RADEON by default (the legacy opensource driver included in Mesa), which has no Vulkan support.
