How can I disable my fingerpad?

I assume it's as simple as unloading or blacklisting a particular module, but I never know how to figure that kind of stuff out. If it helps, I have an Asus K53e. Help would be much appreciated.

Re: How can I disable my fingerpad?

Does sound like what you're looking for?

Disabling it through udev is more radical (ie difficult) than removing a module, but I think evdev handles mouses and touchpads (and also keyboards afaik), so that would remove virtually all your input devices, and you don't want that.

Re: How can I disable my fingerpad?

You can also use Option "Ignore" in the touchpad stanza of the evdev conf under /etc/X11/... - details in man xorg.conf .

Re: How can I disable my fingerpad?

As I understand it, it is not a matter of disabling it when an external mouse is detected. Rather to disable it when typing.

Otherwise you can disable it completely either in BIOS (probably) or with 'synclient TouchpadOff=1'.

Re: How can I disable my fingerpad?

What DE are you using? If you're using KDE "synaptiks" is very good.

Re: How can I disable my fingerpad?

I'm running Awesome. I just realized that my touchpad is working without ever having installed the synaptics package. I removed the touchpad section from 10-evdev.conf and the touchpad is STILL loading! Maybe it loads with the keyboard? I'd like to get the synaptics driver loading though. When I type a synclient command, I get:

Couldn't find synaptics properties. No synaptics driver loaded?

I have the default 10-evdev.conf file:

#
# Catch-all evdev loader for udev-based systems
# We don't simply match on any device since that also adds accelerometers
# and other devices that we don't really want to use. The list below
# matches everything but joysticks.

Section "InputClass"
        Identifier "evdev pointer catchall"
        MatchIsPointer "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev keyboard catchall"
        MatchIsKeyboard "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev tablet catchall"
        MatchIsTablet "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev touchscreen catchall"
        MatchIsTouchscreen "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Re: How can I disable my fingerpad?

I just discovered that my touchpad is actually being loaded by the "evdev pointer catchall" and not by the "evdev touchpad catchall" identifier. That might explain why synaptic is not working. Any ideas?

Just stumbled across this post https://bbs.archlinux.org/viewtopic.php … 23#p961423 with the same problem. Doesn't look like it was ever solved...

Re: How can I disable my fingerpad?

I don't want to hijack the thread, but I have the same problem as you! I was able to solve it with using Lars's wiki link to .xinitrc I was able to solve it. So I just want to thank Lars for that

Re: How can I disable my fingerpad?

It looks like this is a common problem on Asus laptops, namely, that the touchpad is detected as a Logitech Mouse. I have not been able to find a solution, though I have found a workaround in disabling the touchpad device via the xinput command.

Re: How can I disable my fingerpad?

There is a kernel patch that has been filed with the relevant bug on Linux' Bugzilla. See https://bugzilla.kernel.org/show_bug.cgi?id=27162 for the report and https://launchpadlibrarian.net/71387234 … 6.38.patch for the patch. I compiled the kernel from ABS with the patch and it does indeed work. Unfortunately, I'm not a dev, so I don't know how to commit the patch or how to tell if it has already been committed for 3.0.
