<div dir="ltr">Hello Eric, I’ve seen in several places that the reason Sentelic’s driver doesn’t have edge scrolling is due to patent concerns. Perhaps absolute mode was overzealously removed for the same reason. Yes, I would love some help! If we can get this to work, do you think it will be possible to merge this upstream? I feel bad for all the people out there with this touchpad. Some have even gone as far as to remove it physically and replace it with an $8 one[*]. It would also be great to be able to say that this touchpad works better on Linux than on Windows. Greatly appreciated, David.

The X touchpad driver (aka synaptics) requires absolute position reports to work. That said, it seems that the original driver [1] had both relative and absolute mode (cf fsp_onpad_icon()). It would be interesting to find out why in the kernel merge, it was the relative mode which was kept, although absolute mode looks much more obvious for a touchpad. If this is just a wrong decision (ie: absolute mode works fine with the hardware), you just need to patch the kernel driver, and it should work automagically with the X.org driver :-) I don't have the hardware, but I can help you with kernel driver hacking if you need guidance :-) See you, Eric [1] <a href="http://fsp-lnxdrv.svn.sourceforge.net/viewvc/fsp-lnxdrv/trunk/src/kernel-driver/sentelic.c?revision=37&view=markup" target="_blank">http://fsp-lnxdrv.svn.sourceforge.net/viewvc/fsp-lnxdrv/trunk/src/kernel-driver/sentelic.c?revision=37&view=markup</a> </blockquote></div></div>
