Red Hat Bugzilla – Bug 1271012
touching screen only changes cursor position
Last modified: 2015-10-14 01:43:26 EDT
Description of problem:
Touch Screen in FC22 is basically not working. Touching screen anywhere and cursor get there, second touch and cursor simply disappear, however system seems still track position correctly ( if i click button on the mouse - cursor become visible at the position of the screen where i touched my finger last ).
If I have two windows open next to each other - touching screen with finger does not change focus between windows. I cannot open any menu of any window and etc.
On the other hand - if i open Activities via moving mouse to top left corner - then touching screen i see focus being changed properly where i touch - but i cannot activate any window.
Version-Release number of selected component (if applicable):
[root@localhost ~]# evemu-describe
/dev/input/event0: Power Button
/dev/input/event1: Power Button
/dev/input/event2: Elo TouchSystems Optical Touchscreen 02.04.77.02.
/dev/input/event3: Elo TouchSystems Optical Touchscreen 02.04.77.02.
/dev/input/event4: Elo TouchSystems Optical Touchscreen 02.04.77.02.
Fresh install FC 22 on ELO TouchSystem, all updates applied. Reproducible always.
Is there any additional information i can provide to help investigate this ?
pls record a touch sequence with evemu-record and attach the output here, thanks.
I will have to apologize and close this bug.
Turned out - ELO controller was misconfigured and the only way to re-configure properly is to use windows + crystalTouch Manager software from vendor.
After all this, touch working as expected under linux.
Not sure if this was a factory mistake or something else, but i have not encounter this in the past year out of 10 ELO devices of the same model i had to configure.
Thanks for your prompt attention.
no worries, thanks for following up on it
