Hi

I would be grateful for your advice regarding my macbook pro (1,1) running Intrepid Ibex and open source radeon driver (not fglrx).

It suspends and wakes up fine - but after it does, I can't use my trackpad anymore.

How do I set different mouse and trackpad speeds on Windows 2000 or XP laptop?I just got a wireless mouse for my laptop, and it is more sensitive than my trackpad. I went in to the Control Panel to lower the mouse pointer speed for the wireless mouse. This affected the trackpad, and now it is not sensitive enough. How can I configure these speeds separately?Thanks.

after you resume and it is not working, run 

sudo modprobe -r appletouch

then

sudo modprobe appletouch

Many thanks cyberdork - is there a way to make it happen automagically ? Perhaps a script or similar which gets executed after wake up from suspend ... just thinking aloud.

Cheers, Anando.

I poked around a bit and added 


modprobe -r appletouch
modprobe appletouch

But that does not work for me. I'd be grateful for any advice.

Incidentally, after resume, my USB mouse works for me.

Cheers, Anand.

So I assume reloading the module worked?

You should be able to add modules that you want unloaded on suspend and reloaded on resume in /etc/default/acpi-support

Yes, reloading the module worked like a charm. Sorry I should have mentioned it earlier.

So, if I add appletouch to STOP_SERVICES, it would work. Do I understand you correctly ?

Cheers, Anando.

It isn't a service, so no that wouldn't work.

I was referring to the "MODULES=" section, but from reading the top section of this file, it is depreciated now. I am not sure where to configure it.

I have the same problem, no solution yet? Thanks

Andrea,

Yeah - I am awaiting a tip from our more experienced friends as well ...

A temporary solution is: after you wake up from suspend, and presented with your desktop with no trackpad working, do the following:

[B][FONT=Courier New][COLOR=Purple] sudo modprobe -r appletouch sudo modprobe appletouch[/COLOR][/FONT][/B]

  • Press [FONT=Courier New][COLOR=Purple]Alt+F2[/COLOR][/FONT] - this will open the 'Run Application' dialogue box
  • Type [COLOR=Purple][FONT=Courier New]xterm[/FONT][/COLOR] and press enter - this will open a terminal for you
  • In the terminal, type (in succession):

[COLOR=Black]Now you should have your trackpad working again.

This is a minor inconvenience - but one nevertheless. I wish there was an automatic way of modprobing appletouch upon wakeup - anyone ?

Cheers, Anando.

Well, you should be able to add those commands to a script similar to what you tried before, but those scripts don't seems to be executed.

According to the acpi-support file, it sounds like gnome-power-manager should be handling this now, I would start looking for its documentation.

I think I have solved this problem! :guitar:

Maybe it's not exactly a smart solution but it works on my Macbook Santa Rosa 4,1 !

Just try to follow theese steps:

open the file /etc/default/acpi-support with your preferred editor:

sudo gvim /etc/default/acpi-support

find the line:

*SUSPEND_METHODS="dbus-pm dbus-hal pm-utils"*

and replace with:

*SUSPEND_METHODS="pm-utils"*

save, then type:

[B]touch /etc/pm/sleep.d/99-macbook_fix sudo chmod +x /etc/pm/sleep.d/99-macbook_fix sudo gvim /etc/pm/sleep.d/99-macbook_fix[/B]

and write in it:

[I]#!/bin/sh

modprobe -r appletouch modprobe appletouch[/I]

save, reboot (I don't know if it is really needed but I did) and try to hibernate and wake up your mac!

I must thank the author of this webpage who inspired me the solution:

Let me know if it works for you too!

Bye Andrea :p

I suggest you to read the webpage I linked before, there's something strange (a bug) with acpi which may shorten hard drives lifetime..

Please excuse me for my bad English. :-?

#14

Hey Andrea - Awesome - I got this to work in 2 out of two suspend/wakeups so far. I will wait for a few more times before I mark this thread as SOLVED.

Please excuse me for my bad English. :-? This problem has been around for awhile and the function is disabled in Ubuntu by default because of it.

I just rebuilt my kernel having replaced drivers/input/mouse/ appletouch.c with the file from the latest 2.6.28 kernel. It's had a load of changes. So far I've the mouse has restored from suspend perfectly every time.

The modprobe solution worked for me, but it doesn't seem to be reading xorg.conf when the trackpad comes back... so every time i suspend i end up with the default trackpad settings.

does anyone know how to make xorg.conf be reread without restarting X?

is there a way to make this happen via modprobe?

[COLOR="Red"]EDIT[/COLOR]: OK so this problem only happens when i run the commands from a terminal... when i suspend, for some reason it restores the mouse settings...
