Trouble with the touchpad while typing
Hi, I have Trouble with the touchpad while I type, almost since ever, currently with XFCE in Leap 15.2. The touchpad activates randomly, apparently touched by my hand and destroys what I typed. I have in settings "Disable touch pad while typing" set to 2 seconds. Type "SynPS/2 Synaptics Touchpad". Edge scrolling. This is supposed to impede the trouble I have, but it does not. If I type and I try to move the mouse pointer it doesn't respond till two seconds have passed, which is a nuisance I would accept if it worked. There are two types of incidents. One, the cursor location suddenly moves several paragraphs up in the middle of typing a word, thus within centiseconds. Certainly inside the 2 seconds protection. Two, a large portion of the text I'm typing suddenly gets selected, again in the middle of typing a word (I type fast), so that on the next letter I type the entire highlight gets replaced with that next letter, erasing at times all my work. In the first case, I can select the offending text and move it to the correct location, or hit undo. In the second case, I have to use undo, so I don't actually lose my work. Almost always it happens inside Thunderbird. At least, i don't remember it happening in other apps. It is possible that the protection I need is from accidental tap, not accidental move. minas-tirith:~ # hwinfo --mouse 40: PS/2 00.0: 10500 PS/2 Mouse [Created at input.249] Unique ID: AH6Q.ZHI3OT7LsxA Hardware Class: mouse Model: "SynPS/2 Synaptics TouchPad" Vendor: 0x0002 Device: 0x0007 "SynPS/2 Synaptics TouchPad" Compatible to: int 0x0210 0x0002 Device File: /dev/input/mice (/dev/input/mouse0) Device Files: /dev/input/mice, /dev/input/mouse0, /dev/input/event1 Device Number: char 13:63 (char 13:32) Driver Info #0: Buttons: 2 Wheels: 0 XFree86 Protocol: explorerps/2 GPM Protocol: exps2 Config Status: cfg=no, avail=yes, need=no, active=unknown minas-tirith:~ # -- Cheers / Saludos, Carlos E.

Do you have syndaemon running? With which options?

As far as I know, syndaemon only disables handling of touchpad itself (touching, scrolling, tap-to-click etc). It does not disable physical buttons if they are present. It is the same with libinput driver which I use. I have the same issue with libinput as well. I am not sure what is causing it. When I try to deliberately touch or move or tap when typing it works as expected - touchpad is ignored. But when I forget about it I get sudden mouse cursor jump. My current guess is when I press on laptop cover it is apparently interpreted as button press (may be loose contact, this notebook is over 5 years old). And because button presses are processed cursor moves. It is also possible that I press on touchstick buttons (I disabled stick itself because it interfered with typing, but I find middle button useful so I left buttons). May be I should try to disable both left and right buttons if I find how to do it in Wayland :)
No idea what starts it. :-?
It should have been started by your desktop settings, but you said you set it for 2 second and here timeout is 1 second so it does not match.

No, the physical buttons are not the problem, they are hard to click.

Exactly.
My current guess is when I press on laptop cover it is apparently interpreted as button press (may be loose contact, this notebook is over 5 years old). And because button presses are processed cursor moves.
Oh. Interesting idea. I do rest the palms of my hands on the cover while I type, yes, trying to avoid the centre of the cover where the touchpad is, but I think now and then the articulation of the thumb to the palm hits the touchpad. This machine is from about 2010, a Compaq Presario CQ61-330SS, with an actual DVD writer unit. It is built solid and thick, not like modern machines. And most of its years it has been sitting on a table with sporadic travels with careful handling. keyboard photo: <https://images.app.goo.gl/T5Ta4wT1JMpeWXG46> general view photos: <https://www.fnac.es/Compaq-CQ61-330SS-Portatil-15-6-Ordenador-portatil-PC-Portatil/a342395>

No, this one doesn't have stick. It has a button to disable the touchpad, with a led that goes red. However, it fails to enable back the touchpad: I have to do ctrl-alt-f1, and back f7 to restore mouse. I must be one of the few that actually likes and uses the touchpad, instead of attaching a real mouse to the laptops: I made a point of getting used to it and avoid the extra cable.
No idea what starts it. :-?

I have changed it to one second yesterday: I'm tired of waiting for the mouse 2 seconds to respond, and anyway, what it is supposed to stop doesn't work... It triggered once on this email. Oh, well, some comfort knowing I'm not the only one. -- Cheers / Saludos, Carlos E. R. (from oS Leap 15.2 x86_64 (Minas Tirith))

how I fixed it went to cordless mouse the did the setting in kde so when the mouse is plugged in it disables the touch pad I like a mouse better any way On 8/1/21 4:12 PM, Carlos F. Lange wrote:

When I was using a laptop machine I had this problem for quite a while; Synaptics settings seemed to not work at all. I disabled the touchpad in my BIOS settings, since I always used a portable mouse with my laptop machine. Leslie -- Distribution: openSUSE Leap 15.3 x86_64
