You running a desktop or x session to run in it?

3

yes,i run in kde ,i use hdmi

4

Dunno as the drm version is new to me and confused by the error maybe just try Ctrl + Alt + F (2 to 6) key to get to another VT and try running it there.

Do the normal glmark2 and glmark2-es run?

5

I don’t have a screen right now, I’ll try it tomorrow

Dunno been a while with the RockPi4 but generally open an xterm glmark2-es2 and it runs.
Thats why I was asking if you where running a desktop as ‘Could not initialize canvas’ reminds me of errors of trying to run a graphical app without an xsession.

The drm version I think should be run from a VT otherwise run from an xterm. I have never run the drm version and just saw “hint: glmark2-drm needs to be run in a VT” and though ok run it in another VT Ctrl + Alt + F (2 to 6)

There some old stuff from when I had a RockPi4 and have a read through as to be honest it takes a month or 2 and I have forgot.

8

I gave up and now use armbian which has 5.10 and 5.13 kernels and it’s awesome

9

Oh what kernel does the image have as yeah panfrost needs a minimum kernel or the fb drivers.
Good as like the kernel Rockpi4 for me was some time ago thought you where just running headless :slight_smile:

10

As in the picture, you can choose from a variety of kernels.
