i have a dell xps 1530 system with opensuse 10.3 installed
cursor goes crazy..
like it jumps here n there..
can somebody help me how to edit xorg file to resolve this problem..

to add some more information to my query..
Actually i started to work on opensuse10.3(kernnel 2.6.22-..) in which the Ethernet card (Marvell Yukon 88E8040 PCI-E Fast Ethernet Controller) is not detected.
and here the touch pad is working fine without any problem.

i found that upgrading the kernel from 2.6.22-.. to 2.6.23-.. enables to detect the Ethernet card and it worked.

but, from then onwards the touch pad started to behave strangely and its kid of jumping on screen.

please suggest me how can i resolve the problem..

many thanks in advance..

What does your current xorg.conf look like?

i am giving here the touchpad section of the xorg.conf file..


and to my astonishment the touchpad works properly immediately after booting in the OpenSuse10.3.. but, when i close the lid of the system for few seconds and open it touch-pad behaves strangely.

I had a similar problem in Mandriva 2008.1 when I upgraded the bios on my XPS 1530 from A07 to A08. This was solved by adding the following parameter to file /boot/grub/menu.lst, see steps below;

edit file /boot/grub/menu.lst
- add the following parameter to the line starting with kernel kernel ............ i8042.nomux=1
e.g. see below:
title linux
kernel (hd0,4)/boot/vmlinuz BOOT_IMAGE=linux root=UUID=c08e84da-01aa-4d6c-b398-1471175ea062 resume=/dev/sda7 splash=silent vga=788 i8042.nomux=1

I did the same in SUSE 11.0. This stopped the cursor from madly jumping all over the place, but now it very slow and has small delays before it even starts moving, when using the touch pad.

The only I have found to solve this is by plugging in a USB mouse. Then the cursor behaves normal in SUSE 11.0.

The fix by changing menu.lst does work for Mandriva 2008.1. Mandriva 2008.1 One works very well on my Dell XPS 1530 and I have no problems with my touch pad.

Hope this helps a little.
