Weird Synaptics Touchpad behavior?
I've got a weird problem with a recently acquired Dell Inspiron 2650
laptop's Synaptics touchpad I'm hoping someone can shed light on. I can
provide more info on request, just the basics here.
I installed the recent Lenny netinstall and immediately noticed that
the touchpad was quite sluggish. Worse, it seems to "click" buttons and
"select" menus in an out-of-control fashion, without my touching the
pad's two buttons, just the touchpad XY surface. Installed kSynaptics
to no effect, removed gpm to no effect.
I thought it must be a worn-out touchpad and actually bought another
one, but serendipitously, as I was booting a FireWire CD-ROM burner via
a FireWire PCMCIA card, the touchpad worked flawlessly. The mount of
the FireWire burner actually failed gracefully, as I think I need SCSI
CD-ROM support or something in the kernel. The touchpad only works
flawlessly when I boot the failing burner. A working FireWire disk,
successfully mounted, lets the touchpad be its old bad self.
So I'm really unclear what the presence of failing FireWire device
might have on the touchpad's behavior. An inspection of the /proc, etc.
areas that are suggested in much of the synaptics trouble/configuration
help around the net don't reveal anything out of the ordinary.
Here is the DIFF of the dmesg file of the two boots: one with the
failing 1394 device that causes the touchpad to behave, the other a
boot where the touchpad works crazily. (On this boot, the main HD was
checked by fsck)
Anyone have any thoughts on how to proceed with this?
Many thanks in advance! Charles
