The moment the stylus gets near the screen the entire laptop freezes and becomes unresponsive (this just randomly started happening) I tried re-installing the driver, but it has not helped (I take all my notes on this laptop), I've been searching for answers and couldn't find the exact problem. I was hoping someone here might be able to help me with the issue...

    New headers are out and the bug seems to be fixed on my laptop (yoga x1 gen 4), just do sudo apt update && sudo apt upgrade and reboot – Dominus Apr 13 '21 at 07:47

I had the same problem on my Lenovo Yoga C740 with kernel 5.8.0-45 on Groovy, fixed by downgrading to 5.8.0-44.

Problem solved apparently it was an issue with corrupted data in the kernel for the wacom2 stylus driver, it was fixed by updating the entire kernel.

  • Thank you for this advice. Have you any documentation about this ? How to update the kernel to this patched version ? By the way, there is a bug report on launchpad https://bugs.launchpad.net/ubuntu/+source/libwacom/+bug/1920682 – jomuller Mar 25 '21 at 10:02
  • The problem was apparently not solved, at least as of 5.8.0-48. I also had to revert to 5.8.0-44. – MrUser Mar 25 '21 at 14:47
