 Posted: Fri Mar 21, 2014 6:04 am Post subject: [Solved] Q: How to disable touchpad while typing? |
 |
|
This laptop I'm using has a rather large touchpad, and whenever I type something, my palm brushes the touchpad and the mouse pointer moves all over the places. Is there a ways to disable the touchpad while I'm typing? I'm using Fluxbox.

| look @ synaptics wiki, theres an option for palm detection that you can extract out from the wiki's information. |

syndaemon do the job.
I use those options:
and call it at session startup.

It looks like either I don't have a touchpad (I think I do) or it's not recognized. How should I proceed from here?

does your systems /etc/portage/make.conf contain this, and did you

The touchpad can be something else than PCI (PS/2 port or USB, for example)

Here is what I have.
| Code: | $ cat /etc/portage/make.conf
...
INPUT_DEVICES="evdev synaptics"
$ lsusb

|
"D-WAV Scientific Co., Ltd" seems like the touch screen, not the touchpad. "--changed-use --deep" didn't make any difference. Considering that the touchpad is working fine, I'm not sure what to look for at this point.

The best way is to take a look at dmesg and Xorg.log

Here are "Xorg.0.log" and "dmesg".
Xorg.0.log
http://pastebin.com/s4tVjVQ7
config/udev: Adding input device PS/2 Generic Mouse (/dev/input/event4)
dmesg
http://pastebin.com/UmShiP6C
psmouse serio1: alps: Unknown ALPS touchpad: E7=73 03 50, EC=73 02 02
input: PS/2 Generic Mouse as /devices/platform/i8042/serio1/input/input5
The laptop is only a few months old, and in fact, I'm not able to start X if the kernel is 3.10.x or older. The LCD is a touch screen, and I have no USB mouse attached to it. I see a few references of "PS/2" in the logs, although I'm not sure that's the cause of syndaemon not finding the device.

So it's a PS/2 connected touchpad. You can use the Synaptics driver, without problem (ALPS is compatible with synaptics).
You have then to create a personnalised configuration file for X11 where you define the behaviour of your touchpads (tapping, scrolling, palm detection...)

That was already tried (https://forums.gentoo.org/viewtopic.php?p=7523676#7523190) or do you mean it still needs to be enabled elsewhere?
What I think we need to do here is to get the device recognized first such that it's not just seeing it as generic but supports its specific features; so, searching for "73 03 50" "73 02 02" online yields some bugs and forum threads on the subject. From a quick look, there appear to be some patches making itself into the Linux kernel through linux-input; trying a new git-sources every now and then could reveal to him if it has made its way to the mail Linux git repository.
Meanwhile, possible workarounds might be to use a shortcut program together with a script to use `xinput ...` to enable/disable the touchpad manually whilst typing. |

But that's what he tried; and as you can see from the link in my previous post, it says "Unable to find a synaptics device.".
Granted, given the changes in this thread; he could try that command again...  |

Is the synaptics driver installed? It is not loaded by Xorg.
Did you provide some xorg.conf? Can you check if you don't force ps/2 mode in it?

| It might also be an Elantech touchpad (don't know if it's relevant, but I've had some issues in the past for not having Elantech compiled in my kernel). |

Here is what I did.
| Code: | cd ~/tmp
git clone http://github.com/he1per/psmouse-dkms-alpsv7
mv /usr/src/linux/drivers/input/mouse /usr/src/linux/drivers/input/mouse.backup
cp -r psmouse-dkms-alpsv7/src /usr/src/linux/drivers/input/mouse
Build kernel as usual.

I shamelessly stole the idea from the Ubuntu site (http://askubuntu.com/questions/398568/psmouse-serio1-alps-unknown-alps-touchpad-in-a-lenovo-ideapad-flex-15). The difference is that they use dkms (Dynamic Kernel Module Support), but I'm not sure how to set that up (if you know what to do, please share your knowledge), so I just copied the patched source to the kernel directory. Now the touchpad is correctly recognized. Thanks everyone for taking time to respond.
