You've only built qtbase. That means you have no Wayland client plugin.
ok, Wayland isn't needed now - so its ok, but a window would be nice :)
The configure output is confusing. It says "yes" for a bunch of X11 things, but
the "XCB" section only has "no":

Though none of them are about XCB itself, one would conclude it is enabled.
The hint here that GLX wasn't enabled.
i don't know how - is there something to force glx
so im getting an configure error for missing dependencies?
forcing -xcb gives me these configure output (https://pastebin.com/ML8QCJRQ)
XCB:
Using system-provided xcb-xinput ..... no
GL integrations:
GLX Plugin ......................... yes
XCB GLX .......................... yes
EGL-X11 Plugin ..................... yes
but also configure fails with
ERROR: Feature "xcb": Forcing to "ON" breaks its condition:
QT_FEATURE_thread AND TARGET XCB::XCB AND TEST_xcb_syslibs AND
QT_FEATURE_xkbcommon_x11
i've double checked every required package that is needed and can't find
a missing package

In any case, the XCB plugin didn't get built:
> linux@linux-virtual-machine:~/qt6_dev/qt6-build/plugins/platforms$ ls
> libqeglfs.so libqlinuxfb.so libqminimalegl.so libqminimal.so
> libqoffscreen.so libqvkkhrdisplay.so libqvnc.so
So this build has no XCB or Wayland, that's why you can't start applications.
If you just want to test an application that starts and ends, you can use the
offscreen one.
