Macbook 5,2 Trackpad problems

Hello,

Fedora 24 runs well on my macbook, but the touchpad exhibits horrible behavior when making small motions.

It seems like when I try to click x's or adjust windows with precision movements, the cursor jumps around and is not precise.

There does not seem to be a GUI option to adjust this, other than touchpad speed which doesnt really help.

Any advice is appreciated.

Hi,

Two drivers can manage the touchpad :

  • Synaptics : smooth behaviour.
  • libinput (more recent driver, less options) : fast moves even if with low sensibility set.

You may use the second one. To check it, run in a terminal : grep -e "Using input driver" ~/.local/share/xorg/Xorg.0.log and an output can be : (II) Using input driver 'synaptics' for 'ETPS/2 Elantech Touchpad'

One solution :

  • Install synaptics : sudo dnf install xorg-x11-drv-synaptics
  • Then remove libinput : sudo dnf remove xorg-x11-drv-libinput
  • and reboot.

if the cursor jumps on small movements that sounds like a bug. File one against libinput and I'll have a look. Make sure you attach an evemu-record output from such a movement so I can reproduce it.

for the record: libinput and synaptics do not conflict with each other because the server decides which driver is assigned. but libinput relies on driving all devices, so you may miss out on some features (disable-while-typing for example). GNOME does not support synaptics anymore, so you'll lose on the settings panel for the touchpad too.

Thanks. I will need to learn how to generate the evemu-record before I can respond.

Basically the cursor is very sensitive and is hard to use when precise movement/clicking is required.

Hello.

Right now I am using libinput and synaptics is not installed on my machine.

I have ready other posts saying libinput and synaptics conflict with each other. Would this be the case if I install synaptics alongside libinput?

Thanks!

Hi, I haven't experienced any issue using both drivers. Just, the system determines which driver to use and to switch between them could be tricky. On one of my systems, the touchpad uses synaptics and for the mouse libinput (I don't know why, but works flawless). Regards.

How can I make libinput run for the keyboard, and synaptics for the touchpad? That would be the best of both worlds (or the worst of both if not implemented correctly).
