Touchpad extremely sensitive and will not click drag

**Capt. Cautious** · 07-16-2005, 05:05 PM

I have a HP ze4500 laptop. I am using Knoppix 3.8/3.9. the touchpad in winblow$ is sometimes stiff sometimes mucho light touch. I have palm check at near max and it still is so sensitive I often have the cursor in a much different place when I look at the screen. It is slow and often very frustrating. In Knoppix it requires the very lightest touch possible and palm check, well let's just say it almost exists. Does anyone have a suggestion as to how I can improve this in Knoppix? I would appreciate it. Thank you

I have a ze4500 series notebook too, I used to have problems with the touchpad. I then switched to Kanotix, which is based on Knoppix. The support for the touchpad is not so great in Knoppix but it works just fine in Kanotix. You might give that a shot.

Thanks, I haven't tried that distro yet. Does the new DVD have any better support? I don't read German very well so I'm waiting on the English version.

I unfortunately don't read German at all, so I am awaiting the 4.0 EN release as well. Till then, Kanotix is working quite well for me and I recommend it highly.

Well Try again, I accidently erased the post I had started. While I was thinking about how the touchpad workes I accidentlly dropped a piece of kleenex in it and watched the movement. Hmm I thinks... Then I took a piece of tisse and folded it once and then tried it Very good results! not idel but eminently usable. I too am looking for the En ver. of the DVD. I wonder how much more is on the DVD vs: the Lite. With the transparant decompression/compression will it be 9.4GB or aroiund 18 GB. It will be interesting to see. Have you looked at the beata 2.0 of open office? BTW, Kanotix was prety good but I guess I just like the feel of Knoppix better.
Thanks a lot

Every time I've run into a laptop that has a flakey touchpad (super-sensitive, jumpy, or tap-click not working) under Linux 2.6 kernels, this fixes the problem:

Code:

psmouse.proto=imps

Pass that parameter at boot (with Knoppix, type it as you would any other cheat code. For more permanent installs add it to your lilo or GRUB configuration file). 2.6 kernels mis-detect the touchpad and that will tell the kernel's mouse driver to use the imps protocol, which restores sanity to the world (well, to the touchpad, anyway).

I too have lost my drag ability when upgrading from knoppix 3.2 to knoppix 3.8. I there a way to get the driver off the 3.2 disk?

No, the drivers are from two different branches of code and are not compatible in the way that you want them to be. You will have to seek a solution within knoppix 3.8.
