Description of problem:
the installation program has gone through great strides since rh6,
but in normal rh62 i have not been able to get my wheelmouse to
work with imwheel. It seems that one needs an IMPS2 setup,
instead of PS2. However, when I do that, the mouse goes nuts
because the touchpad cannot think of itself as an IMPS2. So
I feared roswell would not fare better.
It actually did seem to fare a little better, it installed
the 4th and 5th button for the wheel action in the XF86Config-4
file. But i fear i must have stumbled on a serious hardware
The obvious solutions *seems* to be to disable the touchpad,
but I seem to remember that that didn't work. On my next
boot (that may take weeks, since linux is normally stable :-)
I will change that and check if rh71 is already able to copy
with this bettter. In the mean time, perhaps anaconda can warn
about such mice on laptops where people can have 2 (and now even
For reference: this is a Dell5000 Inspiron laptop.
Steps to Reproduce:
I'm not following - you have a built in touchpad and an external wheelmouse
attached to a PS/2 port on the laptop?
that's correct. The dell5000 has a builtin touchpad, which is a PS/2.
The wheelmouse is on the external PS/2 port.
I had some initial comments/problems with kudzu when this mouse was on the USB
port, and switching back to PS/2 only mode causes some problems. That is
described in bug# 50921
All of the laptops that I've tested on disable the touchpad automatically when a
second mouse is plugged in. For some reason, that doesn't seem to be happening
on your machine. I don't know if this is something we can even fix.
We don't have a Dell 5000 in the test lab, so I can't get a reproducible test
scenario. Deferring to a future release.
This hardware does not seem to have support (probably due to lack of free
documentation). We cannot fix these problems unfortunately.
