Synaptic Touchpad adding psmouse and evdev to Kernal

eliran · 01-09-2007, 11:20 AM

I have problem activating the synaptic driver in my suse 10.2.

I been trying to follow the this howto ( http://gentoo-wiki.com/HARDWARE_Synaptics_Touchpad ) but I do not understand the first part.

According to my kernel I do have the CONFIG_INPUT_EVDEV and CONFIG_MOUSE_PS2. But when I try to run modprobe psmouse and modprobe evdev, I get an error message:

lifebook:/ # modprobe psmouse
FATAL: Module psmouse not found.
lifebook:/ # modprobe evdev
FATAL: Module evdev not found.
lifebook:/ #

If someone have any suggestions? I will appreciate detailed explanation because I am new to the linux world.

My Kernel

CONFIG_INPUT_MOUSEDEV=y
CONFIG_INPUT_MOUSEDEV_PSAUX=y
CONFIG_INPUT_MOUSEDEV_SCREEN_X=1024
CONFIG_INPUT_MOUSEDEV_SCREEN_Y=768

CONFIG_INPUT_MOUSEDEV=y
CONFIG_INPUT_MOUSEDEV_PSAUX=y
CONFIG_INPUT_MOUSEDEV_SCREEN_X=1024
CONFIG_INPUT_MOUSEDEV_SCREEN_Y=768

You have them compiled into the kernel, not as modules. You don't need to do the modprobe thing.

Next you need to install the synaptics driver. Since you're not using Gentoo, you probably don't have Portage. Hence, the emerge synaptic won't work. Here is the homepage for the synaptics driver that Gentoo provides in Portage. Maybe SuSE provides the synaptics driver, it looks like only the source is available from that website.

The rest of the HOWTO you're following looks distro independent enough that you should be able to just follow it.

Just from my knowledge, how do you psmouse and evdev are already loaded?

Actually, I can't say with 100% certainty. You tried to load the modules and that failed. You're using a big monolithic distro like SuSE that has to support a myriad of hardware. Many people are still using PS/2 mice. From those three nuggets, I deduced that the support was compiled into the kernel. However, I could be wrong.

If you want to know for sure

Code:

cd /usr/src/linux &&
su -c 'make menuconfig'

Enter your root password when prompted. Work your way through the menus as follows.

Code:

Device Drivers --->
     Input Device Support --->
          <*> Event Interface
          [*] Mouse --->
               <*> PS/2 mouse

If there are asterisks like above, it is compiled into the kernel. If there is an M in the brackets, then they're built as modules. If the brackets are empty, there is no support.

I install the synaptic driver and follow the directions.However, I have one question regarding the xorg.config file. I do not know if I need to delete the old InputDevice or I to keep it?
I paste the text below.

I tried to give the synaptics mouse the number 2, but the X server did not load. So, I need to use vi to edit xorg.config file to its previous stage.

Section "InputDevice"
Driver "mouse"
Identifier "Mouse[1]"
Option "Buttons" "5"
Option "Device" "/dev/input/mice"
Option "Name" "PS/2 Generic Mouse"
Option "Protocol" "explorerps/2"
Option "Vendor" "Sysp"
Option "ZAxisMapping" "4 5"
EndSection

Section "InputDevice"
Driver "synaptics"
Identifier "Mouse[1]"
Option "Device" "/dev/psaux"
Option "LeftEdge" "1900"
Option "RightEdge" "5400"
Option "TopEdge" "3900"
Option "BottomEdge" "1800"
Option "Finger" "25 30"
Option "MaxTapTime" "20"
Option "MaxTapMove" "220"
Option "VertScrollDelta" "100"
Option "MinSpeed" "0.02"
Option "MaxSpeed" "0.18"
Option "AccelFactor" "0.0010"
# Option "Repeater" "/dev/ps2mouse"
# Option "SHMConfig" "on"
EndSection

I deleted the InputDevice for mouse. The results were the X-server did not load. So I re-edit the xorg.config file to it original stage. I thing part of my problem is have to do with the SuSe, the howtos I follow did not work on my computer. So, I post a new thread with on the SuSe forum (http://www.linuxquestions.org/questi...28#post2581028)

Thank you for your help.
