 looks like libinput needs to be rebuilt for libwacom10, else build depends of qt and other things are now uninstallable
 e.g. vlc
 Ummmm. wrong channel
 may as well post the info though as it impacts Qt... ;)
 /# apt-get install qtbase5-dev
 Reading package lists... Done
 Building dependency tree... Done
 Reading state information... Done
 Some packages could not be installed. This may mean that you have
 requested an impossible situation or if you are using the unstable
 distribution that some required packages have not yet been created
 or been moved out of Incoming.
 The following information may help to resolve the situation:
 The following packages have unmet dependencies:
  libwacom2 : Depends: libwacom-common (= 1.12-1) but 2.0.0-1 is to be installed
 E: Unable to correct problems, you have held broken packages.
 I created https://salsa.debian.org/qt-kde-team/qt/qtwayland/-/merge_requests/5.
 But I can't test-build because libinput is broken in Debian too. (re @RikMills: @mitya57 https://www.reddit.com/r/kde/comments/s8etjq/the_patches_required_for_wayland_and_nvidia_to/)
 awesome. thanks!
[15:32] <fvogt> mitya57: If you take the frame callback threading patch, you have to backport the various pending mutex fixes from upstream as well
[15:32] <fvogt> Otherwise you get hangs
[15:33] <mitya57> fvogt: So KDE's branch is broken?
[15:44] <fvogt> mitya57: Yep
[15:44] <fvogt> (As is upstream)
[15:46] <mitya57> Maybe you can create a merge request upstream adding the missing patches?
[15:48] <fvogt> If you mean for the qtwayland fork, it's a bit early for that, they're not even reviewed upstream
[15:48] <fvogt> https://codereview.qt-project.org/c/qt/qtwayland/+/393273, https://codereview.qt-project.org/c/qt/qtwayland/+/393828/1 and https://codereview.qt-project.org/c/qt/qtwayland/+/393826/1
[15:48] <mitya57> Ok. I will remove the frame callback threading patch for now.
[15:48] <mitya57> Thank you for the information!
[15:51] <mitya57> fvogt: Is it this one? "Move the wayland socket polling to a separate event thread"
[15:51] <fvogt> Yep
[15:57] <mitya57> Removed in https://salsa.debian.org/qt-kde-team/qt/qtwayland/-/commit/69d1657b99f5f648. Thanks again.
[15:58] <mitya57> But it is exactly the patch which was referenced by Reddit post linked by @RikMills :-(
[15:59] <fvogt> Yep
[15:59] <fvogt> For proper nvidia gbm support you'd need several unreviewed patches
[15:59] <mitya57> I will better wait.
 seems so :/
