 Posted: Mon Aug 15, 2005 1:32 pm Post subject: Synaptics touchpad odd behaviour [Solved] |
 |
|
Building my first Gentoo laptop and just come across my first laptop specific problem. The laptop is a HP Compaq nx9005.
After configuring xorg.conf and testing the configuration my synaptics touchpad appears to be working correctly; however when I use the buttons the cursor shifts a few pixels up or to the right. The same problem occurs when moving the cursor normally. It has a tendancy to shoot towards the top right hand corner. It moves almost exactly the width or height of the cursor itself.
Anybody come across this before or have any ideas?
Any help would be greatly appreciated
Mike

Thanks for the post, still no luck though. May I ask what model of laptop are you using? |

I have a Dell 6000. Hard to believe that it is actually a specific thing with the HP hardware.
This might help...

Most people seem to find that it works fine. One fellow said the following:
| Quote: | | The Synaptics trackpad works fine in Linux with the 2.4 series kernels. It works in 2.6 series kernels with this http://w1.894.telia.com/~u89404340/touchpad/index.html driver. I find the accleration annoying so I always set the Min and Max speeds to "0.12" and the acceleration to "0.00". This allows me to have a fast pointer but with no accelerations. |

| I have experienced this mouse jumping before. I think it might be static related as it does not always happen for me. Is it a constant problem or intermittant? |

Thanks for the links, I was aware of a few sources relevant to my hardware, although I hadnt come across the second one. I'm taking a good look now. |

Its a constant problem. The cursor has a tendancy to move either upwards or towards the right upon either touching the pad or clicking the buttons. |

Problem solved. I should be more carefull when compiling my kernel 
For others experiencing the same problem make sure you have the following in your kernel.
| Code: |
Device Drivers ---->
Input device support ---->
<*> Event interface
[*] Mouse
<*> PS/2 mouse
|
And try booting without another mouse plugged in. My USB mouse was interfering with the touchpad and causing problems.
Thanks for the input though guys  |
