Bug 20021

In addition at least twice the trackpad has gone completely dead (Ie no cursor movement either). In both cases it resolved itself in about 1 min. Whether it was what I did (Ie, trying to move it madly, clicking both with taps and clicks, go to console and back) or if it would have done it on its own I do not know. When you are in the middle of working and the mouse cursor disappears, waiting calmly is not my natural reaction. I Think this is related to the click bug, but cannot be sure.

Again today, the mouse pointer froze. at-ctrl-F2, alt-ctrl-F1 did not unfreeze it.

Plugging in a usb mouse made botht he trackpad and the mouse work, but when I unplugged the usbmouse, the desktop often did not respond to clicks. If I clicked on some desktop icon, nothing would happen, but if I did AC-F2, AC-F1 suddenly that thing that I clicked on would open. Ie, the system would remember that I did click but did nothing with it, until I did the AC-F2, AC-F1 dance. 

Something is seriously wrong with the trackpad handling.

-------------------------------------------

Note that windows on the Desktop (KDE Plasm5) do respond to clicks. It is the icons on the desktop that do not. So it is not some generic trackpad issue. It is very specific to the Desktop.

And sometimes the trackpad pointer freezes. At least once it seemed to think there was already a finger on the trackpad (there wasn't) since moving my real finger scrolled the screen the cursor happened to be over when the pointer froze.

Note-- an additional symptom. Usually when the trackpad pointer passes over an icon, that icon is "selected (greyed border surrounds the icon)"  When the above "non-responsiveness to clicks on the desktop", that icon selection also does not happen. Ie, there is no reponse of the desktop to having the cursor go over the icon. However as I said, if I click on the icon (noreponse) and then to AC-F2 AC-F1 that program associated with the icon I clicked on starts up. Ie, the touchpad actions seem to be being blocked, and are released on the cycling through the consoles.

Well, its been acouple of days using libinput instead of synamptics as the x11-driver-input  and I have not seen this symptom reappear yet. 
synaptics was the default touchpad driver. Should this now be changed to libinput?
Of course I have tested only with one touchpad (Dell xps13 9360 version). But certainly people should be alerted to the possibility.

And of course, using libinput the problem has sort of reappeared (much less severely) Ocasionally touchpad taps do not work, a number of times in succession. Ie it is not just a single tap that is missed. Clicking onthe lower part of the trackpad still works as a right button, but a single tap suddenly does not work. Then shortly thereafter it works again. ie, something seems to be blocking the touchpad taps as clicks for a short while. 
Note that though now the taps do not work on the programs they will sometimes still work on the desktop.

*** Bug 20240 has been marked as a duplicate of this bug. ***

It seems to be getting worse. About 1/4 of tap to click fail (lower left clicking still works). At least once the trackpad completely froze--no cursor movement no clicks, no tap to click. Ie, trackpad completely disabled. I had to reboot to  get back the trackpad. 
I have a-c-y setup to  disable the trackpod and a-c-t to enable it. typing a-c-t did nothing in that situation. a-c-bksp got me out of X but the trackpad was still disabled. Only reboot worked.

Something is flakey with the trackpad driver.

I have now been using libinput for about 6 months. It is really not up to the task of being a trackpad driver. It is far too sensitive and with the large trackpad on the Dell XPS13 I use the cursor is always being tapped (causing the cursor to jump all over the page I am typing leading to mistakes or destructions of commands I am trying to type in) or double tapped (causing random stuff to dumped into the cut and paste buffer and then being dumped onto where I am trying to type.) While synaptics had perhaps too many options, libinput has none, and the default is far from flawless or even very useable.

Having never seen the problem of desktop icons that are invisible to the mouse/trackpad pointer, that's exacly my problem here on fully-updated Plasma 5
Mageia6.1 on HP450 Probook.
  The problem manifested itself after the latest s/w update just before leaving on a trip.

All desktop icons appear to be invisible w.r.t. selection by mouse and trackpad pointer, though no problem with icons in Panel, so can still get work done.
  Even if create new desktop icon, it is then unselectable (so cannot be removed!)  

  Clue: The other user on the system does not have the problem...

So question: What $HOME setting can make desktop icons unselectable?

[When I get back to base I will try a restore of both / and /home/user.]
