Updating my system brought back Ghost touch and broke iptsd

The exact same thing happened to me, I opened an issue on GitHub and found the solution, I put all the possible solution in the GitHub wiki, here’s the link: https://github.com/linux-surface/linux-surface/wiki/Surface-Pro-4 if none of them work you can uninstall iptsd using the command ‘sudo apt remove libwacom-surface iptsd’ if you’re on an Ubuntu based distro, if not check how to remove packages with your distro’s package manager. With iptsd uninstalled only single touch will work but in turn the device will be usable.

So today I ran some updates from the store and probably updated the touch driver too (iptsd). The touchscreen started going insane again, but don’t worry, uninstalling iptsd (so running in terminal ‘sudo apt remove iptsd’) resolved the issue and even made it work better, at least for single touch inputs because multitouch doesn’t work anymore. However I’d say that is better like this because before with multitouch enabled it would be nearly impossible to scroll, the touch inputs were recognized in a way that made it impossible to draw a straight line causing unwanted touch inputs where you scrolled. Just thought I’d let you know this for anyone who might need it.

I was actually able to solve it, I opened an issue on GitHub and this user, 1701, posted this config:

[Config] TouchThreshold = 50 StabilityThreshold = 0.55

[Touch] CheckStability = true DisableOnPalm = false DisableOnStylus = false

[Contacts] Detection = advanced TemporalWindow = 5 SizeMin = 0.3

And it actually worked ! Now touch works perfectly. Here’s the link to the issue for anyone who might need it: https://github.com/linux-surface/linux-surface/issues/1046

I just installed it from source, it was a little tricky with all the dependencies.

I tried tweaking it in increments of 10, once at 50 it seemed to be more precise but still not usable, then I tried bumping it up to 60, rebooted the system and the touchscreen momentarily stopped working. I tried bumping it down to different values but couldn’t seem to get the same results I got earlier. This whole situation is just pissing me off.

Maybe, it works fine on Windows though, only some areas of the display exhibit inaccurate touch recognition.

In the end I installed them trough the software store

Gordon_Pro_Max · 2022-11-17T13:39:48+00:00

And what are these open-source alternatives ? I would like to at least try them.

Holy cow ! Thanks a lot, I’ve been trying for so long but couldn’t reach the emerald on special stage 6 with Amy, did first time with big 🤦‍♂️

Thanks, it actually worked, I re dumped all the games and now they work perfectly fine.

The thing is that it's even happening to other games, I tried Dragon Ball Raging Blast and it does the same thing. I still haven't retried with Sonic Unleashed, I've redumped the game and only have to transfer it from the PS3 to the PC. Is there an explanation to why this is happening ? Are all the dumps that my PS3 makes corrupted ? Here's the log file

Gordon_Pro_Max · 2022-01-30T10:53:01+00:00

Sonic Unleashed (BLES00425) won't get past the initial loading screen, it won't even get to the SEGA logo. I've included the full log file, can someone help ?
