[Bug 1723857] Re: onscreen keyboard appears whenever i touch touchscreen

2018-01-02 Thread Jens Forker
update to #49
even after installing 18.04 updates on Jan 2nd the following feature persists: 
a few times a week the cursor goes nuts - it looks like it's jumping to the 
lower left corner (gnome desktop), clicking, and thereby calling the program 
tiles onto the screen. Then clicking again making the tiles disappear, clicking 
again calling the tiles,. sometimes with quite a high frequency, turning 
the laptop pretty much useless when it's "trapped" in this state. Whatever you 
try it's always calling the tiles :-(
This happens even if I'm not touching the notebook at all!!
I couldn't find anything to influence this behavior. Even after rebooting it 
continues! But at some random point in time the jumping stops and the notebook 
can be used as before and works like a charm - until the jumping starts again.

Because I used the fix from @keringar (see above) the on screen keyboard
is not coming any more. But for me it looks that the root cause of the
osk popping up is the cursor jump/click.

update to my entry #47:
installed ubuntu 18.04 daily build from Dec 11, 2017 on the Lenovo IdeaPad/Yoga 
2 13 with touch screen. For one day everything went fine except one single 
appearance of the on screen keyboard (osk). On the second day the osk got 
crazy, appearing that frequently that working with the mouse or touch screen 
was practically impossible. But the cursor didn't jump (to lower left corner) 
as it did with 17.04 and 17.10.
The osk sometimes flickered really fast giving the impression of being turned 
on/off at least 10x/second - without me touching anything on the laptop!
Then I applied the fix provided by https://askubuntu.com/users/750621/keringar 
(Thank you!!) and now I can use the laptop again.
Testing continues

[Bug 1723857] Re: onscreen keyboard appears whenever i touch touchscreen

2017-12-11 Thread Jens Forker
Hello,
having the same problem on a Lenovo IdeaPad/Yoga 2 13 (with touch screen): 
ubuntu 17.10 fresh install, the on screen keyboard (osk) always pops up. But 
ALWAYS in conjunction with the cursor being found in the lower left corner. 
On the same laptop running Ubuntu 16.04.3 and 17.04 (running Unity) I had the 
nasty problem that always the trash bin opened (because the cursor jumped to 
the lower left corner - where the trash bin is located - and clicked) 
independent on what I was doing. That made the laptop unusable (running fine 
under Win 8, hence no hardware defect).
Now with 17.10 (Gnome) the trash bin is no longer in the lower left corner. But 
my feel is that the cursor is still jumping (and clicking) to the lower left, 
thereby 'calling' the osk. Again this happens that frequently that the laptop 
is unusable :-(   really nasty.
Universal Access settings: osk = off (if I enable osk, then the desktop 
freezes!!).
The fix of Keringar prevents the osk from popping up - but the cursor still 
continues to jump to the lower left corner :-(.
