[gpm]GPM problems

[Troy Schultz]

I recently upgraded my GPM from version 1.19.6 to 1.20.0 and have tried
the synaptics patches from Peter.  I am mostly happy with things, except
I am experiencing problems with X no longer processing pointer or
keyboard events.  This happend only a few time with version 1.19.6 and I
was never able to determine why.  Now with version 1.20.0 it is much
more frequent.

I have tried both native 1.20.0 and with Peter's synaptics patches, I
have the same problems with both versions.

My system is a Compaq Presario 2710 with a synaptics touchpad+4-way
scroll key, firmware version 5.8.  I am running RedHat 7.2 with kernel
2.4.17, ACPI version 20020225, and Xfree86 Version 4.2.0.

I start gpm using the following;
"daemon gpm -Rimps2 -t synps2 -m /dev/mouse"

Under XF86Consig-4 the pointer sections is as follows;
Section "InputDevice"
	Identifier  "Mouse0"
	Driver      "mouse"
	Option	    "Protocol" "ImPS/2"
	Option	    "Device" "/dev/gpmdata"
	Option	    "Buttons" "5"
	Option      "ZAxisMapping" "4 5"
	Option	    "Emulate3Buttons" "yes"
EndSection

The problems I experience are as follows;
#1: access console using <CTRL><ALT><F1> and return to X using
<CTRL><ALT><F7> no response from X for either mouse or keybaord.  This
happens 100% of the time with gpm 1.20.0 and only happened once with gpm
1.19.6.  After this I must restart the system.  During this
/var/log/messages do not report anything out of the ordinary.

#2: after X screen saver is running and returns to normal X display,
loose mouse and sometime keyboard.  This happens approx. 20% of the
time.  After this if I ssh to the notebook and restart gpm things work
again.  During this problem /var/log/messages reports "gpm[PID]: garbage
or tossing PS/2 data"

#3: sometimes during normal running, usually related with a window
close, I also experience mouse and keyboard loss as in problem #2. Same
results and fix as #2 also.

I have also tried gpm using the msc repeater and X configured for
MouseSystemsMouse and still had the same results, and also don't have
the nice scroll that Peter's patches provide.

Any assistance anyone can provide would be greatly appreciated.
