Touchpad jumpiness
Touchpad is somewhat jumpy on default install 14.04 with latest updates. XPS is DE model. BIOS is A03.
Is this fixed in 15.04? If so, could there be a Fixed in 15.04 label to indicate this?
I still see this jumpiness in 15.04. Isn't this a duplicate of (or what does it distinguish from) issue #3 ? I guess these issues need clearer definitions, e.g. like bugzilla mozilla user stories:
- What did you do? (steps to reproduce)
- What happened? (actual results)
- What should have happened? (expected results)
For 14.04 jumpiness issue, here is the fix: http://www.dell.com/support/article/us/en/19/SLN297219/en
@MarcusMoeller, are you able to confirm whether this issues is distinct from #3 (and if so what makes it different), and whether it can be fixed using the link @superm1 provided?
Ubuntu 14.04 by default uses the PS2 driver. Ubuntu 15.04 by default uses the I2C + HID driver. By definition they will not have the same mouse behaviors. Any of these discussions should distinguish which version is being used.
The link I provided enables/forces the I2C mode on Ubuntu 14.04 using a backported I2C driver and HID stack. If there were issues (such as palm detection) missing in Ubuntu 15.04, I wouldn't expect them to work properly here either.
@superm1, have you seen the related trackpad issue just now opened by @anaran? Not sure if you can replicate or are already aware of this?
I took a quick look and can't replicate it. If it's causing errors for you, you can configure the region for TopEdge using synclient to be lower, and that should help.
@superm1 Tried setting TopEdge 200 (and verified value is taking effect via synclient) but can't see a change. Still detects events on frame above touchpad and very top of touchpad.
Are you using the Dell OEM Ubuntu install? Cause they run kernel 3.13, upgrading to 3.19 helped me a lot.
