I've been 'living with' a jumpy TouchPad on my new Laptop since I installed Current + Kernel 4.4.1 last month.
Everything else is working VERY well, including the Killer Wireless 1535 Firmware and the NVidia 960 with the Nvidia 361 Driver.
The jumpy TouchPad was more than a little annoying because over the years, I have become completely dependent on the mouse for Cut-n-Paste ( seems I can't remember what I read to re-type it at the commandline or enter it in a source file without using the mouse <G>).
Syndaemon and various Synclient tuning didn't help much if at all.
I am not complaining by any stretch of the imagination but this morning, I marshaled up my courage and applied the Pat's Current Updates from last week to my Production / Work LapTop.
Anyhow, after installing Pat's Updates, including installing 4.4.3 and reinstalling Eric's MultiLib and the NVidia 361.28 Drivers, etc, I noticed that my `fix-mouse` script threw an 'X Error of failed request: BadValue' error due to this setting: FingerLow=51
Code:
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 131 (XInputExtension)
Minor opcode of failed request: 37 (X_ChangeDeviceProperty)
Value in failed request: 0x116
Serial number of failed request: 22
Current serial number in output stream: 25
I adjusted FingerLow=50 to eliminate the X Error ( and FingerHigh=53 ) and now my mouse is behaving !
Woo Hoo !
I looked at the Kernel ChangeLogs and saw nothing directly related to the psmouse or synclient ...
Does anyone know what may have fixed my touchpad ?
Mostly curious but I want to take a snapshot of whatever might have fixed it for future update-proofing if necessary.
Thanks.
