Drifting nubs

Hi !

As I was testing some emulators on my Pyra, I realised that the nubs (or at least the left one) were drifting a lot, so much in fact that it made playing with them almost impossible (it happened on several emulators, both on Buster and on Bookworm). Oddly enough, I could not reproduce this behaviour with the cursor on the desktop. Do you think it is a software or an hardware problem, and would you happen to know if there is any way to remedy this ?

I tested the nubs with "jstest-gtk" and it clearly showed that they both often got stuck in a certain direction. So it clearly is an hardware problem.

This problem was already discussed there :

To which ED answered :

Usually, this happens if the screws are too tight, especially the one near the heatsinks and the one inside the battery case.
This squishes the nubs together so they don't move properly.

I will try that (even though I wouldn't like to loosen them too much) and let you know.

I loosened the screw near the heatsink, and the two visible ones inside the battery compartment. The device is now dangerously unstable, and ... did this not change anything. My only hope would be that there is another screw beneath the sticker and try to loosen it; but I don't want to peel it off, since there is important information there, unless there actually is one and it can be peeled off without destructing it. Does someone know anything about this ?

So I finally peeled off the sticker, and discovered there is no screw under it... Therefore unless there is another solution which I don't know about, it seems to me that this is an hardware problem that cannot be fixed unless by replacing the nubs...

Well, thanks for posting your findings, even if it wasn't a win. The info might still help if someone else has the same symptoms.
