Until now, unfortunately, there seems to be no progress with integrating the patch: https://patchwork.kernel.org/project/linux- input/list/?series=523049
However, the siduction kernel 5.14-rc7 (5.14~rc7-1~exp2) already has integrated the patch. Could Ubuntu do the same? Is here anyone who could help accelerating the approval of the patch so that it could still make it into the 5.14 kernel.

The trackpoint cursor often suddenly jumps to an edge/corner, because the hardware/firmware sometimes reports wrong coordinates / loses sync. Currently, the Trackpoint is barely usable and it's impossible to productively work using it. For a long while, Elantech has not yet put forward (nor confirmed) a firmware update. However, there is a Linux kernel patch mitigating the firmware bug. The kernel bugfix discards the wrongly reported packages by the Elantech hardware. This solves the problem for the user. *Solution:* Please apply existing kernel patch here. https://bugzilla.kernel.org/show_bug.cgi?id=209167 Bug entry in the Linux Kernel.org Bugzilla https://bugzilla.kernel.org/attachment.cgi?id=295733&action=diff Diff of bugfix *T14s and X13 are Ubuntu certified:* The Lenovo Thinkpad T14s and X13 are Ubuntu certified, but apparently this hardware issue has slipped the Ubuntu certification process! https://ubuntu.com/certified/202006-27978 and https://ubuntu.com/certified/202006-27979 *Further information:* https://forums.lenovo.com/t5/Fedora/T14s-AMD-Trackpoint-almost-unusable/m-p/5064952?page=1 Discussion on the bug in the Lenovo forum.
