I tried to installa xubuntu 16.04 (kernel 4.4) thinking that maybe it would work better due to dell upstreaming but the problem is the same

[ 5040.494101] [drm:intel_dp_link_training_clock_recovery [i915_bpo]] *ERROR* failed to enable link training

I'm going to do a last test and try with the recovery partition

I managed to made a bootable usb fromt he recovery partition using dell-recovery program, started up and installed ubuntu from scratch (i choose to recovery the whole disk, not only the linux partition). After a couple of hours in suspend the touchpad is dead.

Unfortunately I think I have to ask for a replacement, just hope they don't give me back a refurbished unit.

Strange. I think I did the same thing and it worked for me. Maybe try to change UEFI or legacy boot options and reinstall again? Just an idea.

Hey revelant, did you mean that you had the same problem with the touchpad and a fresh installation of ubuntu solved your problem?

@Gpstuff,

Did you still need help with this? If so, please add me as a friend and send your service tag and email address. We'll start a case.

@Gpstuff,

Understood. Glad to hear it's solved. Credit to your good troubleshooting.

Hey Justin, thank you for the reply, in the end the problem was just a bad hardware connection, I'll mark this post as solved.

i am really MAD at dell that this is still an issue!
i recently bought an 9315 and i am running Pop_OS! on it.

i came across this bug on the very first day but noticed it will not occure if i not charge it while i use it.

on battery it was working fine for a month, 

but since today, without changing anything this bug occures EVERYTIME. i freshly reboot, it is accurete for 5-10 seconds and then changes to the inaccurate state. working with it is impossible. DELL do something!

i also noticed something else:

usualy, when it was in a laggy state, it did not go back to be responsive again untill i reboot.

now when it gets laggy, i leave it alone for a few seconds and it becomes responsive again. after 5-10 secons of using it gets laggy again
