Hello,

I have installed Fedora 21 on my notebook Asus UX303LN Zenbook

I am running Fedora with the latest updates:

linux localhost.localdomain 3.17.7-300.fc21.x86_64 #1 SMP Wed Dec 17 03:08:44 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

The touchpad left and right clicks works ok. And I can double tap on the touchpad to highlight a sentence. If I try and perform 2 or 3 finger scrolling, all that happens is the mouse pointer moves.

This very is annoying as I normally use the 2 finger scrolling to browse the internet, ebooks, and documents.

Under Settings | Mouse & Touchpad All I have is properties for primary button, double click, and pointer speed.

Has anyone else experienced problems with their touchpad scrolling.

Only just updated my laptop. I too have touchpad issues. Two finger scrolling is OK but edge scrolling does not work!

I fix it using

[]$ synclient VertEdgeScroll=1
[]$ synclient HorizEdgeScroll=1

but I have to issue these everytime I log on. I am looking for a better solution. Yours was just the first hit on my search.

Settings before I issue the commands are:

[]$ synclient -l
Parameter settings:
    LeftEdge                = 1773
    RightEdge               = 5471

I think I have found the real answer for our problem. Issue the command:

[]$gsettings set org.gnome.settings-daemon.peripherals.touchpad scroll-method 'edge-scrolling'

I am now working without problems.

As an alternative you can use the dconf editor gui. This shows more options which could work for you, including replacing 'edge-scrolling' in my example with 'two-finger-scrolling'. Seems a shame but you don't appear to be able to configure both without the use of synclient. Just another example of gnome stopping us making best use of our hardware.

@Paulf, Thanks for your suggestion. However, when I run the following command:
sudo synclient VertEdgeScroll=1 Couldn't find synaptics properties. No synaptics driver loaded? Maybe my Asus uses a different mouse driver. However, I don't know what? Many thanks for any other suggestions
