XPS 15-9575 2-in-1, touchpad freezing

A week after the original trackpad has been replaced, no more issues, on battery or mains. I will chase Dell to try and get an extra 3 months of warranty, as I wasn't really able to use the laptop until the part was replaced. 

I have the same issues with my trackpad. They replaced my trackpad, after two oder three weeks the issues started again. After that, Dell replaced my mainboard and the trackpad. I enjoyed three weeks with a great working trackpad, and now the issues are starting again. :Angry:
I don't think that this is a software Problem. The trackpad has the same issues while using it in the BIOS for a while.

I've had issues yesterday with one of my apps showing weird video artefacts, weird coloured lines and boxes (but in that window only, all the others were ok), and I was still able to use the other programs, and the trackpad was 100% responsive. The laptop wasn't very hot, but there was GPU activity for some reason. Had to restart about 2 h later, as the whole thing become unresponsive (very slow to switch apps). I've had this problem from day 1, with 3D games and sometimes in tablet mode - but the trackpad issue was the main focus. 

I believe a major part of the problem lies with the GPU driver. I've been switching between the latest Intel-provided beta and latest AMD-provided Adrenalin software. Neither causes problems in 3D benchmarks, although the laptop gets quite hot after 2-3 hours of testing. Will keep on changing different settings, but if this doesn't get fixed by end of January with a new release of GPU drivers, will have to chase Dell again - no idea what to ask for, most likely a motherboard replacement. 

I have the latest BIOS and Intel 530 driver. 

GPU driver versions for reference: 

Dell website - don't bother, way behind, April 2018.

Intel website - Version: 18.10.2 (Latest) Date: 11/8/2018 GFX_Radeon_BETA_Win10_64_18.10.2.exe (seems to be identical to the previous Adrenalin 18.10.2, just Intel rebranded)

AMD website - 18.11.2  Driver Version: 25.20.14007.1000 radeon-software-adrenalin-18.11.2-minimalsetup-181119_web.exe

Looking at the release notes for AMD's latest: "Fixed Issues. Radeon RX Vega Series graphics products may experience elevated memory clocks during system idle." but as I've mentioned with my app artefacts, they still seem to have some work to do on the driver. Also wondering about how long will it take Intel to just take this driver, rebrand it, and add it as 18.11.2 BETA on their support page - IIRC it was 2 weeks for 18.10.2.

I'm running Fedora Linux 29.  Was seeing the same issue about once a day mouse would freeze for about 3 minutes.  Updated to bios 1.20 and didn't help.  3 days ago disabled self panel refresh and haven't had the issue since then.  Hopefully that did the trick.

Update - The issue is back.

Dell came and replaced my touch pad today.  Waiting to see if the issue comes back.

Yes exactly and mine is fresh out of the box! I'm tired of this.

I had the same problem, touchpad go crazy, especially with low battery.

Try this workaround:

• - Disable touchpad when a mouse is connected -
• Disable all the stupid 3 o 4 finger gestures win 10 is using

I had strong improvement.

I hope Dell is doing something to fix this, the only suggestion I recieved from the support is to reinstall the OS. Without any serius hope of improvement. Very unprofessional

Ciao

I have been intermittently having the trackpad issues, and last week, one of the keys on my keyboard stopped working properly. I sent it in to have the keyboard and the trackpad replaced. Will update the thread once I get it back.

Update: issue seems to include battery life... I'm running move mouse (https://github.com/sw3103/movemouse) to keep system from going asleep and otherwise have little running save only a chrome browser, outlook, skype and my battery dies at 3 to 3.5 hours (in "battery saver" mode even).

1. So now I have trackpad issues;
2. Above requires me to kill driver for Radeon RX Vega M GL Graphics, so I can use trackpad, but means I lose driver features;
3. @Battery life @ 3.5 hrs max.

System is 1 week and 3 days from delivery. Hate to go thru return process, but looks like it is a must. Will forgo the 2 in 1 and try the 9570 model on account of bigger battery and different video card. Really wanted this one to work as I thought I might enjoy 2 in 1 feature and preferred the usb-c ports. 

Oh well.

What? The designated solution is to return the 9575 and get a different model?

I read this thread a couple of weeks back after I encountered the same issue after buying my 9575 from Best Buy. Once I read that this has been going on for months and Dell still can't fix the issue, I returned it and got a MBP instead. Such a shame that into December they can't fix something so fundamental on an otherwise excellent machine. Best of luck to you guys.
