Touchpad cursor gets stuck in screen corner

[bogdan]

I'm sorry if this has been posted before, i was unable to find it. Ever so often my mouse cursor just jumps into the top left screen corner and the touchpad stops working. In the console, gpm still works ok and if I plug in a usb mouse it also works ok, but the moment I touch my touchpad it just jumps back in the corner. I looked into Xorg.log and I saw "Synaptics DeviceOff called" for no apparent reason. My laptop is a HP nx6325 if you need full specs.

Relevant Xorg conf:

Code: Select all

Section "InputDevice"
        Identifier  "Touchpad"
        Driver      "synaptics"
        Option      "Protocol" "auto-dev"
        Option      "SendCoreEvents"
        Option      "SHMconfig" "on"
EndSection

Thanks for any help.
Note: this behavior is as far as I can tell pretty much random. It occurs in pretty much all new distros I tried. For Ubuntu and Suse it's constant and annoying. After about 5 minutes the touchpad is dead. For Debian and Gentoo it's quite rare, but still happens. Older versions of Ubuntu until 7.10 (i was using ubuntu before the problem start appearing) worked fine though.

Thanks for the post. I have the same version of synaptics drivers and it is enabled in the kernel else it wouldn't work at all

This is from dmesg

Which version of xorg-server are you running?

x11-base/xorg-server
Available versions: 1.2.0-r3 1.3.0.0 1.3.0.0-r1 1.3.0.0-r2 ~1.4-r2

Additionally, here's some other info I pulled that may or may not be useful

Code: Select all

  Xorg.log

(II) LoadModule: "synaptics"

I updated to 1.3.0.0-r3 today. I haven't experienced the problem today yet but, as it is random from what I can tell, I doubt it won't happen again

Java doesn't work now though.

Edit: Just happened again now.

I found a way to get it working again after it gets stuck without restarting X. You need to compile the PS/2 mouse support in the kernel as a module and when it happens you just unload the module "psmouse" and load it again. Still don't understand if it's kernel or synaptics driver bug..

Hi,

I'm having a similar problem, my synaptics touchpad works normally for a while, and then all of a sudden it gets stuck in vertical scroll mode. It won't move on the screen but if I drag my finger across the touchpad it flips my windows, or scrolls down a document I may be working in. If I plug in a usb mouse it works fine, but the touchpad is still stuck in scroll mode.

I see the following errors in my Xorg.0.log file:

I have xorg-server-1.12.2, xorg-x11-7.4-r2, and xf86-input-synaptics-1.6.2 installed.

Hope that a solutions pops up soon. This is most irritating.

Kind Regards
