Just a stab in the dark and i might be repeating myself, but did you disable secure boot in BIOS?

Odroid H2+ = secure boot disabled.  Can't boot from USB:

• USB3.0 port & USB 3.0 stick = no
• USB3.0 port & USB 2.0 stick = sometimes OK, depends on port
• USB2.0 port & USB 3.0 stick = no
• USB2.0 port & USB 2.0 stick = sometimes OK

New PC (MeLE Quieter2) = didn't check secure boot, but no issues booting from USB.  Haven't done anything in BIOS, figured I'd circle back to optimize the BIOS settings once I got a stable Linux install done.

Lets get a working Linux + kernel first, then knock the other issues off one by one
 

I've got MX21 ahs & rt kernel installed.  non-ahs MX21 resulted in 800x600 display from the start.  Switching to ahs fixed the display (to 1920x1080) until I installed the rt kernel, then it came back on re-boot.

Cannot change the resolution (or anything else) in 'display settings'.

I had trouble with the LinuxCNC VM on my iMac.

I created a file called

/etc/X11/xorg.conf

containing

Though I don't recall where I got the "Modelines" bit from.

However, up to the point that I added that I, too, could only have 800x600

I created an xorg.conf file in /etc/X11/ and pasted what you had.  Edited the text to '1920x1080' where appropriate, as well as the monitor name.

Rebooted.... and MX21 is now broken and won't start to desktop.  Stops at 'Welcome to MX Linux! [somethign cut off by screen] 3:Cannot probe codecs, giving up.

I'll try bookworm again now.

Finally - Bookworm is good to go.  RT kenel installed, no display resolution issues.

uname -a
Linux debian 5.17.0-17-rt-amd64 #1 SMP PREEMPT_RT Debian 5.17.3-1 (2022-04-18...

So now what's the next step?  There are so many 'how-to's' available I'm not sure which one to start from.  Seems like all the other times I've made it this far I've picked the 'wrong' one and wound up with issues later on.

I jumped the gun and tried this from Tommy's post on Bookworm:

sudo apt install linuxcnc-uspace linuxcnc-uspace-dev mesaflash

That was stupid easy. LCNC is installed and starts.  Hopefuly I haven't installed the 'wrong' version.

Of course, there's a problem.  Axis and gmoccapy load, but all qtvcp screens fail with an error.  log attached.
