I just fumbled my way through converting my old hal mouse configuration |
| 2 |
to the "new" way of putting it back in xorg.conf (where it belongs :) |
| 3 |

Peter Hutterer gave me a link to his blog, which was very helpful: |

Turns out that the xorg-server-1.9.x defaults work okay with my cheap |
| 9 |
M$ optical wheel-mouse, but not with my expensive trackball mouse without |
| 10 |
a wheel. |
| 11 |
|
| 12 |
When hal first came along I added a custom .fdi file for the trackball |
| 13 |
by adapting the settings I formerly put in the InputDevice section in |
| 14 |
my old xorg.conf (where it should have stayed). |
| 15 |
|
| 16 |
Now that hal has gone, I've adapted the hal settings, with help from |
| 17 |
Peter's blog, back to xorg.conf but with some important adjustments. |
| 18 |
|
| 19 |
Here is my original (pre-hal) mouse config from xorg.conf: |
| 20 |
|
| 21 |
Section "InputDevice" |
| 22 |
Identifier "Mouse0" |
| 23 |
Driver "mouse" <----- note the old driver |
| 24 |
Option "Protocol" "auto" <--- this is now redundant |
| 25 |
Option "Device" "/dev/input/mice" <--- now redundant |
| 26 |
Option "Emulate3Buttons" |
| 27 |
Option "EmulateWheel" <----- because I have no wheel |
| 28 |
Option "EmulateWheelButton" "8" <---- new default is "4" |
| 29 |
EndSection |
| 30 |
|
| 31 |
My new (post-hal) version: |
| 32 |
|
| 33 |
Section "InputClass" <----- note the new word "Class", not "Device" |
| 34 |
Identifier "trackball" <----- can be anything you want |
| 35 |
MatchProduct "ImExPS" <-----*new*. Matches the product name! |
| 36 |
# Driver "evdev" <--- this is redundant so I removed it. |
| 37 |
Option "AutoServerLayout" "on" <--- see Peter's blog |
| 38 |
Option "Emulate3Buttons" "on" |
| 39 |
Option "EmulateWheel" "on" |
| 40 |
Option "EmulateWheelButton" "8" <--- change the default |
| 41 |
EndSection |
| 42 |
|
| 43 |
If you have no InputDevice sections (many people no longer need them) |
| 44 |
then "evdev" will automatically discover and configure your keyboard |
| 45 |
and mouse without being asked, applying the xorg-server defaults. |
| 46 |
(That's why I deleted the Driver "evedev" from my config.) |
| 47 |
|
| 48 |
Only if the defaults are wrong for your machine do you need to change |
| 49 |
them using the stuff I outlined above. |
| 50 |
|
| 51 |
At first I tried using the old "mouse" driver in the old way, but it |
| 52 |
seems to fight with "evdev" over who's in charge and between the two |
| 53 |
of them I got error messages galore and the mouse didn't work right. |
| 54 |
|
| 55 |
The nice thing about the new "InputClass" thing is that you can have |
| 56 |
as many such sections as you want, each one being specific for an |
| 57 |
individual mouse or keyboard -- note the "MatchProduct" keyword |
| 58 |
picks out my trackball mouse specifically and doesn't prevent me from |
| 59 |
using my simpler wheelmouse if I want to, where the default settings |
| 60 |
would 'just work'. |
| 61 |
|
| 62 |
Enough for now. |
