I normally use the MX Linux Fluxbox version. Recently, I tried using vanilla mwm (Motif Window Manager) for fun, and it really worked! I plan to use it like this for one or two weeks. Although the sound didn't work on the first try, thankfully, MX Linux provided an extraordinary "pipewire-start" that fixed the problem immediately!

I'm having a lot of fun :)

Verified checksums on downloaded ISOs (KDE, XFCE, Fluxbox).
Seven other distros UEFI boot AOK on my Thinkpad X1 Carbon Gen3.
Booting into GRUB2 mode fails with a black screen.
Booting into Normal mode fails with both (systemd) and (sysinit) with a prompt to load the kernel.
MX Linux is _supposed_ to work w/ Ventoy.
Anyone make it work?
