Description David Paschal 2012-07-30 23:28:36 UTC
Description of problem: On an HP EliteBook 8460p laptop, middle-button emulation (pressing the left and right buttons simultaneously) works for the two buttons "below" the trackpad (farther away from the keyboard) but not for the two buttons "above" the trackpad (closer to the keyboard).  Both sets of left and right buttons function normally as left and right "mouse" buttons when not pressed together.  (Pressing the upper-left and lower-right (or vice-versa) buttons simultaneously also does not simulate a middle-button event.)


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

xorg-x11-drv-synaptics-1.6.2-1.fc17.i686


How reproducible:

Always


Steps to Reproduce:
1. Use either left button to select some text in a terminal window such as Konsole.
2. Press/release the lower left+right buttons simultaneously.
3. Press/release the upper left+right buttons simultaneously.
4. Run "xev".
5. Press/release the lower left+right buttons simultaneously.
6. Press/release the upper left+right buttons simultaneously.

Actual results:

2. Selected text gets pasted as expected with a middle "mouse" button press.
3. Selected text does NOT get pasted, and instead separate left and right "mouse" button events are generated (right-click menu pops up).

5. xev reports middle-button press/release events (not separate left- and right-button events) as expected:

ButtonPress event, serial 35, synthetic NO, window 0x4c00001,
    root 0x166, subw 0x0, time 24750716, (135,175), root:(137,198),
    state 0x0, button 2, same_screen YES

ButtonRelease event, serial 35, synthetic NO, window 0x4c00001,
    root 0x166, subw 0x0, time 24750864, (135,175), root:(137,198),
    state 0x200, button 2, same_screen YES

6. xev reports separate left- and right-button press/release events:

ButtonPress event, serial 35, synthetic NO, window 0x4c00001,
    root 0x166, subw 0x0, time 24752210, (135,175), root:(137,198),
    state 0x0, button 3, same_screen YES

ButtonPress event, serial 35, synthetic NO, window 0x4c00001,
    root 0x166, subw 0x0, time 24752220, (135,175), root:(137,198),
    state 0x400, button 1, same_screen YES

ButtonRelease event, serial 35, synthetic NO, window 0x4c00001,
    root 0x166, subw 0x0, time 24752363, (135,175), root:(137,198),
    state 0x500, button 1, same_screen YES

ButtonRelease event, serial 35, synthetic NO, window 0x4c00001,
    root 0x166, subw 0x0, time 24752363, (135,175), root:(137,198),
    state 0x400, button 3, same_screen YES


Expected results:

Pressing the upper left+right trackpad buttons should generate a middle-button event, as is the case with pressing the lower left+right trackpad buttons.


Additional info:

$ xmodmap -pp
There are 12 pointer buttons defined.

Comment 1 Fedora End Of Life 2013-07-04 02:30:22 UTC
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. 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 WONTFIX if it remains open with a Fedora 
'version' of '17'.

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 prior to Fedora 17's end of life.

Bug Reporter:  Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 17 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 to Fedora 17's end of life.

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 2013-08-01 08:31:03 UTC
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 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.

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