Impossible to change touchpad scrolling settings in Xubuntu 15.04

[Brian]

I have tried using synclient to set VertScrollDelta to negative values. I have tried using "Mouse and Touchpad" In "Settings Manager" to reverse the scrolling direction on SynPS/2 Synaptics Touchpad. I have also tried disabling scrolling. Changes are not reflected in any application.

Brian, as per www.dell.com/support/home/us/en/19/product-support/product/inspiron-11-3147-laptop/drivers an update to your computer's buggy and outdated BIOS is available (A05). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.

Once the BIOS is updated, and the information above is provided, then please mark this report Status New.

Thank you for your understanding.

Hi Chris. There are no bugfixes listed in Bios update A05. I am not willing to update the BIOS for this. Futhermore I am appalled you have designated this as a low priority issue when clearly something is fundamentally broken with the Ubuntu input stack.
