A few possible issues here. A look at /var/log/Xorg.0.log might reveal a lot
about the issue.

I run a T16, but I did not buy the optional graphics card.  It might be running
vesa or scfb. (vesa on BIOS boot, scfb on EFI booted systems.) You could be
running the amd or the Intel GPU. The log will tell you what graphics you are
running. If running vesa or scfb, you will have no hardware acceleration and
many other functions won't work. The Intel in mine is an Alder Lake.

You really want either i915 (Intel) or amd kernel module and, likely some added
software, at least for the Intel GPU. Beyond that, I recommend not running the
Intel driver. It will be chosen if it is installed, but the modsetting driver,
built into the basic X software is generally a better choice. The Intel driver
has been in maintenance only mode for at least a few years.

You can confirm the graphics(s) with "pciconf -lv | grep -B 3 -A 1 display".

If you are running an Alder Lake, I can provide my full graphics config which
works well. If you are running AMD graphics, someone else might be a good idea. 

Finally, it is important that the drm* port be rebuilt after any kernel update.
You need to build on a system with the source code for the 14.2-Stable present.
