Now, I've run raspi-config and enabled the new video modes, but glxgears is nowhere to be found. That says it running wayland I think. Except htop can't even find the smell of wayland, but does find 2 or 3 Xorg sessions running. So I'll byte, have they a new tool to replace glxgears? There is not a glxinfo either. > Next problem, ping? > I have only one email address. So I cannot login to the > lcnc forum using the chromium installed on that pi3.

Now, there have been updates to hm2_rpspi.c that I'll need before I do a fresh rebuild of linuxcnc for the pi4. So where can I get the latest version of hm2_rpspi.c? I don't see mention of a commit of it at github.com/linuxcnc, although I have pulled the latest .zip. So I think I am actually making progress, if I've got the faster video... Does anyone know how to check that w/o glxgears??? That of coarse means I've got to put power on the back of the spi adapter board. Short on small fans, I have a piece of an old psu box with a 12 volt fan in it, sitting straddle of the pi4 laying on a piece of a half-built blanket chest, running on the 5 volts x 5 amp supply the pi is running on, and I can just barely feel a small heat on any of the 4 sinks I stuck to it, including the 3.3 volt regulator chip just behind the unused otg port. So that seems to be more than enough cooling. How are the rest of you powering your pi4's? otg or pins 2-6 of the header?
