When did support for the APUs get added to the kernel? My wife got fed up with Windows a couple of years ago, and I tried to set up a dual boot on her HP laptop, but Ubuntu wouldn't display anything above 800x600. The best I could tell was that there just wasn't support (at the time) for her AMD APU, but I can't remember which model it was. All the drivers I found on the AMD website only officially supported 14.04, but even 14.04 wouldn't recognize the proper screen resolutions. I've been meaning to try again since 18.04 was released (or at least see if anything had been added to the kernel), but I haven't gotten around to it yet. Fingers crossed...

Depends on which APU you have and which features you need. The latest Raven Ridge APUs had stability problems until 4.17, anything older should work on 18.04 which ships 4.15. HDMI/Displayport audio support for the older models landed in 4.15 but wasn't enabled by default until 4.17, so in 4.15-4.16 you have to pass the amdgpu.dc=1 kernel parameter for it work.

I recommend 4.19+ if you are planning to use one with Vega. Anything lower will have problems.

Don't use drivers from AMD site, use upstream kernel and latest Mesa release.

I have the A485, Windows is oddly a shit show with drivers. But linux is great with Arch and proton gaming. With the fat battery, it has great battery to boot

I will say Ryzen APU is very janky. The new model should be coming soon. Though it took a year and half for the first mobile apus to become obtainable.

Do you mean ones with Zen 2 / Navi? It might take a while, CPUs and GPUs aren't even out yet.

Not zen 2 / navi. There were some possible kernel patches for zen+ apu. There was a refresh coming for the desktop apus. I can't recall the name though. AMD has been really quite on the mobile front though :\

I see, thanks!
