I just tried my old X61t and found that the stylus
didn't work under
Fedora 42 (a "live" USB stick).
It still works under Fedora 24.
Any thoughts?
I'd boot Fedora and try and figure out *how* the stylus works there.
e.g. which kernel/Xorg module handles it. Then try and see what
happened to that driver in the mean time: is it still included in
recent kernels/Xorg? Has it been moved to a separate package?
Does the touchscreen work in Fedora 42 (when using something else than
the stylus)?
Could this be due to the switch to Wayland?
If it was handled at the Xorg level, that's possible. Have you tried to
use Xorg instead of Wayland (don't know if Fedora still includes Xorg,
but Debian definitely does, so in the worst case you may want to try
booting a recent Debian).
