When I highlight text and go to paste it by pressing both buttons at the same time it only works 10% of the time. The majority of the time it fails (don't paste anything).

When it fails, if I immediately press just the left mouse button about 1/2 the time it will paste.

I don't know if this is recent or not as I just recently started using 2.6 full time and I haven't used all the revisions.

First off do not use ACPI PM timer...

Also, could you please tell me if it's X or GPM and what's in your "InputDevices" section of XFConfig and what parameters are you passing to GPM.

Thank you,

Dmitry

OK

I have these two entries (stock Fedora and what worked with 2.4):

Section "InputDevice"

        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "Protocol" "PS/2"
        Option      "Device" "/dev/psaux"
        Option      "ZAxisMapping" "4 5"
        Option      "Emulate3Buttons" "yes"
EndSection                                                                                
Section "InputDevice"
        Identifier  "DevInputMice"
        Driver      "mouse"
        Option      "Protocol" "IMPS/2"
        Option      "Device" "/dev/input/mice"
        Option      "ZAxisMapping" "4 5"
        Option      "Emulate3Buttons" "no"

EndSection

------

My GPM invocation: gpm -m /dev/mouse -t ps/2

(/dev/mouse is symlink to /dev/psaux)

Here is your other trouble - /dev/input/mice gets data from _all_ mouse-like devices in 2.6 so your touchpad data is processed twice.

Drop the first input section and set "Emulate3Buttons" on 2nd - it does not hurt if your mouse has 3+ buttons.

Good luck,

Dmitry

Ok, it's a bit late here and I can't read anymore... Actually in 2.6 /dev/psaux and /dev/input/mice are synonims (different device node numbers but the same underlying device).

Anyway, your touchpad data is still processed twice ;)
