Software rendering in cinnamon

I have Debian stable with a kernel 5.8 backport to allow a comet lake processor with integrated graphics. How can I confirm what is needed for hardware acceleration.

Is this a virtual machine?

Allen_B · 11-10-2020, 04:40 AM

No, and I don't have one set up on it either. I get this message on startup..

Allen_B,

You could always switch from Cinnamon to Xfce or MATE and see if that resolves the problem:

As discussed in your other thread, I'm stumped as to why the vendor is showing as VMware. I was not aware that VMware sold hardware. As beachboy2 said, you can try Xfce or another DE and see if you get the same, or something different. Exactly what hardware are you using? Is this a NUC?

Allen_B · 11-11-2020, 01:54 PM

No, desktop. The gpu is integrated, intel UHD630. To use the onboard graphics you need the processor version that has the gpu in it.

Maybe I could try a card instead, an Nvidia or an AMD...

My NUC has the same integrated gpu, same CPU. Hardware acceleration works on it.
