Also ... Because this laptop has one of those little "jpy-sticks" within the keypad, tried that as well. It works just fine! Meant to say "JOY-stick" weird. sounds like a hardware issue, I wonder if there's some earthing problem or something. Do you notice a difference whether you're on battery power or plugged in? What's the evemu-describe of the touchpad and your dmesg? I wonder if windows is using a different protocol to drive it and that exposes the bug. Also, when you run evemu-record, do you see the freezes happening in the log, i.e. no events scrolling past whenever the cursor freezes? If so, that further indicates a hw (or kernel) issue. Are you under Wayland or Xorg? any difference between the two? Sorry - I don't even know what Wayland is. But I've pretty much ruled-out h/w problem as I tried the Mint OS also, and like with Windows; no jerky/freeze touchpad. Just now tried it (first time) on battery power. Oh-wow ... weirder yet. On battery power, no jerky/freeze. Then, plugged external power back in and - zap, back to jerky/freeze.

Tried a different (Dell) charger (19.5V, 4.62A) and all works well. The other charger (that apparently caused the problem) is a Dell 19.5V, 3.5A. Tried yet another (After market) charger (19.5V, 3.5A) and got a BIO warning on boot-up that it was a non-Dell and performance may be impaired. Touchpad was jerky. So, obviously, a 4.62A charger is a necessity! I would close this bug if I knew how. Sorry for taking up your time. Maybe this will help someone else. No worries, thanks for reporting back. |
