Touchpad too sensible
 
1 Attachment(s)
Good evening.

First of all: I know synclient, but I do not understand it.

Facts: My wife's notebook has had too much coffee or rather too much sugar in the coffee and the keyboard is apparently lost. I have integrated her hard-disk in my own machine, have dual-boot and a virtual machine to start her Mint-system (17.2 apparently) from Debian.

Observation: The Touchpad is on LSD, when I try to do anything in Mint. The same Touchpad serves me well under Debian for years and continues to execute my commands promptly. Under Mint it obeys a different master, not me.

When I compare the synclient output, I do not see much difference between the distributions. But I may not look at the right variables.

Question: What are your recommendations to reduce the sensibility of the Touchpad in Mint? And in any case, I would like to know, which driver options should I set to which values to alter the behavior.

The output from synclient is attached, anyway.

Thank you in advance.

You can find out more about the touchpad with this command:

Code:

xinput | grep -i touchpad
And also:

Code:

dmesg
Use those commands to see what driver your touchpad needs.

Also, a diff of the two synclient outputs would probably be helpful. That way, you could make them the same and see what effect that has.

I would guess the important key/values are:

Code:

    PressureMotionMinZ      = 30
    PressureMotionMaxZ      = 160
    PressureMotionMinFactor = 1
    PressureMotionMaxFactor = 1
    HorizHysteresis        = 14
    VertHysteresis          = 14

I believe there's also a GUI touchpad configuration tool, found in your System Settings under Mouse & Touchpad.

Thank you for your response.

I use xinput to enable and disable touchpads all the time, but as regards the sensibility, it does not provide much information:

Yes, it is there, but only to show me two sliders, Acceleration and Sensibility, which do not appear to have any influence on the touchpad.

I will try to get more out of synclient and try to manipulate the variables, that you listed, above.

I'm not familiar with Mint, but does it default to using libinput instead of synaptics for touchpad by any chance?

I do not yet know, but will find out. Thank you for mentioning libinput.

Try this on for size next time your cursor acts like a puppy that won't listen to you.

Fn+F9 keys. Hold it down for over 3 seconds.
It works for me in AntiX.

To find out which Xorg input driver is in use, you can use something like
Code:

grep "Using input driver" /var/log/Xorg.0.log

Does this mean you run Mint as a client VM? If so, then (depending on the VM perhaps) I would expect the physical touchpad is not handled directly via the guest, and so might be presented as a more virtual input device (with more limited functionality). For example, I have a Windows 7 host with openSUSE guest, and the touchpad is presented as a mouse...

Thank you for all the input.

Up to now, I have not had opportunity to test anything. My proposition is therefore, that I will get some work done, then report back in this thread. I cannot say, when this will be. Also, I will, before long, take some time off of the Internet and IT in general. There is a heap of work waiting outside and as here, in France, the technology is beginning to be imposed to organize every detail of your daily life, and as satisfying the needs of surveillance and propaganda are the only uses that the folks around me are able and willing to invest in, technology begins to give me diarrhea.

I'd like to keep away from it for a while.

I will just write a quick update in my sqlite2dbf thread, then see a little what happens, and, maybe, go away.

Your post resonates with me as well. I sometimes feel that I'm overdosing on it these days. It permeates our working and personal lives, and we can forget to feed our souls. I have a fond memory of riding bikes around a village area not far from Toulouse with my GF at the time while on holiday visiting her family. Good conversations, food, wine, swimming, and relaxing. I think I'll limit my online activity for a bit as well.

So, this Mint system uses synaptic, in deed.

I could play with the options given by notKlaatu and would now, after very few testing, claim that the situation has improved. I could write 1 whole email without having to rearrange paragraphs which had jumped around in the text and even did some word processing... Now, this is definitely different. My wife sais that she had not noticed anything, but she is the one with the most experience on Mint. She had probably adapted her hand movements with the time.

Thank you all, once again, and with respect to my previous post, I wish you all a happy X-mas, happy easter and whatever you wish for 2017... I'll be on the construction site, meanwhile.

Cheerio.
