I have noticed some of the graphical displays in certain Qubes are slow. I am guessing this is because all graphics are being generated by the GPU.
I just want to confirm that there’s nothing I can do to get some of the GPU power into my system, because the GPU will attach to dom0 and must be used for dom0, and therefore cannot be outside of dom0, right?
There’s no driver or anything I would do in this situation, Qubes is destined to not be graphically fast with only 1 GPU, right?
also, is there any way to plug in a GPU somewhere else and wireless attach it to my laptop? this isn’t for gaming.
Yes, all rendering in qubes is done on the CPU which is super slow. You may have a $4000 GPU in dom0, this will not affect the speed of rendering in qubes. This is because of the isolation, qubes are not allowed to use the GPU device.
Would there be any way to buy a GPU and wirelessly attach it, without using wires, so that if I were in the same area that any GPU processing could be done wirelessly? This is instead of connecting via an Occulink cord.
i had been having a lot of crashes that kicked me back to login screen before crashing again, i finally narrowed it down to being the amd igpu (think 4k 120hz was too much for it). It worked well for a while until it didn’t… on any of the newer kernels.
A cheap solution is to buy a <$100 slim gpu with DP 1.4 if you have a powerful main GPU you want to pass through to a VM for gaming/ML etc.
beat me to the reply!
After some research of <$100 cards i found many had HDMI limited to 4k60hz.
if you have a higher refresh rate monitor, look out for display port 1.4 / 1.4a as its spec is 4k120hz.
Not an issue if your monitor doesn’t support that, but always useful to future proof.
