Xorg synaptics driver problems...
 

Hello everyone,

I've been having some problems with Xorg's synaptic touchpad module. Every so often, when I go to move the cursor, it flies all over the screen and generates random click events! I'll be moving it around, and suddently it disappears and reappears on the other side of the screen, on the far edges, or so, and sometimes it will click on items in my task tray or other windows, sometimes pressing buttons or triggering menus. I just need to move it and it does this. Also, these events are not easily replicated (i.e. I can repeat the same motion and nothing will happen). Does anyone else have this problem?

I use the latest Xorg synaptics touchpad module (0.14.6) on my HP Pavilion dv5000t.

Thank you

I've had similar issues with touchpad drivers before.

What does the synaptic section in xorg.conf look like?

Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "HorizScrollDelta" "0"
EndSection

I also have the "Configured mouse" input device description (i.e. the default configuration), but this caused more problems than the current configuration.

Here's mine....
You can look through the man page to see exactly what everything does.

Thank you for your configuration, but I still have the same problems.

Hmm, odd.. what version of the driver are you using? Have you tried updating it?

The latest: 0.14.6.

Weird, huh?

very strange, how much ram do you have? I have problems sometimes when I'm using a lot of my system memory.

I have 512 MB RAM and 1 GB swap (the latter of which is never used).

Same problem
 

I have the same problem with my HP dv5000 and so far all I've found with possible solutions is turning off the ACPI functions, since they are supposedly at the root of the problem. However, I have a Turion that I think needs ACPI to work optimally and I also like to know how much battery power I have too.

I'd be interested in hearing from anyone about other ideas as to how to fix this Synaptics Touchpad problem.

that's odd. I also have an HP dv5000 model (I forget the actual number), turion with a synaptics pad. did you by any chance upgrade the RAM? I upped mine to a gig and have no problems with my synaptics touchpad.

I have not upgraded my ram. The error that I get is:

psmouse.c: TouchPad at isa0060/serio4/input0 lost sync at byte 4
(repeats a few times)

My touchpad randomly freezes all mice (I have a USB connected as well) and makes random movements on the screen.

What synaptics driver are you using?

I have the dv5000t (Intel T2300 dual core, nVidia GPU, etc). I think you both have the dv5000z (AMD Turion, ATI GPU, etc). I'm not sure how different the boards are...

I haven't upgraded my ram yet, but I'm looking to if it will help.

Here's something interesting: my /proc/bus/input/devices file indicates that I have both a SynPS/2 Touchpad AND a PS/2 Generic Mouse (mouse 0 and mouse 1). The synaptics driver page informs me that other mice have been known to cause interferences with the synaptics driver (i.e. PS/2 mice). Does anyone know how to get the kernel to ignore the non-existant PS/2 Generic Mouse? Thanks.

Hmm, is it in your xorg.conf file?
