Description Chris Halsall 2016-12-01 19:55:04 UTC
Description of problem:

Left mouse clicks are sometimes not acted upon.  Most times they are, other times they aren't.

After a great deal of experimentation, I have found that if a left mouse click is not "taken" by the GUI I need to hold the left mouse button down for up to about 500 to 1000 milliseconds for the signal to be received.

Version-Release number of selected component (if applicable):

Fedora 25 Mate-Compiz Desktop Spin on fresh hardware.

How reproducible:

I didn't see this problem under Fedora 22 Mate-Compiz Desktop Spin.

When I freshly installed Fedora 24 Mate-Compiz Desktop Spin I encountered this a lot.  I then upgraded to Fedora 25 Mate-Compiz Desktop Spin to see if it had fixed the problem.

Steps to Reproduce:
1.  Install Operating System.
2.  Try to work with it.
3.  After several hours of use one finds that one's mouse clicks aren't always being received (possibly only in a multi-monitor configuration).

Actual results:

Clicking on something with the left mouse button doesn't always activate an on-screen GUI element.  This can be anything from a "Next" button on a web-page to simply trying to activate a Mate Terminal.

Expected results:

When one clicks with the left mouse button, one expects immediate results.  Having to hold the mouse button down for up to a second for the GUI to receive the input is a problem.

Additional info:

Hardware configuration: Three screens (3# 1920x1080) being driven by the on-board Intel graphics card and a PCI NVidia graphics card.  My research on previous reports of a similar nature suggests that multi-monitor configurations might be part of the problem.

MB/CPU Configuration: Intel(R) Core(TM) i5-3330 CPU @ 3.00GHz; 32 GB of RAM; 4 TB of storage.

To try to figure out if this was a hardware problem on my end, I tried five different mice in all the available USB ports, plus a PS/2 mouse in the motherboard's available Mouse/Keyboard port.

All exhibited the same behaviour  -- this is not a hardware issue.

I would be happy to provide additional information, and/or run experiments to get to the bottom of this, as requested.

Regards.

-Chris

Comment 1 Fedora End Of Life 2017-11-16 19:36:37 UTC
This message is a reminder that Fedora 25 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 25. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '25'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 25 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Comment 2 Fedora End Of Life 2017-12-12 10:04:23 UTC
Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
