hi @soleblaze, I wondered if you had any progress to report.
Looking at this gist it suggests PalmDetect would be working, but I don't think it is.
MaxTapTime 0 is just disabling that single taps all together, I think, which might make PalmDetect appear to work.
SoftButtonAreas is probably also ineffective in this configuration.
Would be great if you could give issue advancingu/XPS13Linux#14 a try and write a comment.
