Description cam 2011-04-14 20:11:36 UTC 
Description of problem:
Under F14 middle button emulation was disabled as a default, and some config options were introduced and changed to re-enable it. This config that worked in F14 no longer works in F15

Config:
/etc/X11/xorg.conf.d/91-enable-middle-mouse.conf:
Section "InputClass"
  Identifier "middle button emulation class"
  MatchIsPointer "on"
  Option "Emulate3Buttons" "on"
EndSection

The effect of this config is that pressing left and right buttons simultaneously causes a middle mouse press event to be generated. This is useful for opening webpage links in a new tab and for pasteing selected text into text fields.

Version-Release number of selected component (if applicable):
xorg-x11-server-Xorg-1.10.0-7.fc15.i686


How reproducible:
100%

Steps to Reproduce:
1.create config file as shown above
2.test clicking both buttons
3.check xorg.0.log
  
Actual results:
No middle button event; error message in xorg.0.log file

Expected results:
middle button event

I should add, Gnome 3 relies on middle-click on the title bar to lower windows, making this more important.

Comment 8 Peter Hutterer 2011-04-18 04:58:49 UTC 
Not an evdev bug. GNOME has a gsettings schema to enable/disable this session-wide. This key is disabled by default, i.e. after logging in GNOME overwrites the system-wide configuration from the xorg.conf.d snippets.

The key can be manually set with the following command, I don't think there's a GUI item for it yet.

$> gsettings set org.gnome.settings-daemon.peripherals.mouse enabled

For reference on the gnome bug see:

Comment 9 Peter Hutterer 2011-04-18 05:12:54 UTC 
my apologies, forgot the actual key name. The command is

$> gsettings set org.gnome.settings-daemon.peripherals.mouse middle-button-enabled true
Comment 10 cam 2011-04-18 06:23:05 UTC 
Fantastic, that works. I wonder if it is persistent over logins / reboots?
It's worth adding to the release notes for F15 I reckon.

yes, gsettings should be persistent.
