[Fixed?] Cannot use mouse and touchpad at the same time after upgrade

Dell Inspiron 6400 laptop, Synaptics touchpad, external wireless USB mouse (Logitech).

Yesterday I did a full system upgrade which among other packages upgraded

[2007-11-08 00:06] upgraded synaptics (0.14.6-2 -> 0.14.6.99-1)
[2007-11-08 00:06] upgraded tzdata (2007h-1 -> 2007i-1)
[2007-11-08 00:06] upgraded xf86-input-keyboard (1.1.1-1 -> 1.2.2-2)
[2007-11-08 00:06] upgraded xf86-input-mouse (1.2.1-1 -> 1.2.3-1)
[2007-11-08 00:06] upgraded xf86-video-i810 (1.7.4-2 -> 1.7.4-6)
[2007-11-08 00:06] upgraded xf86-video-vesa (1.3.0-1 -> 1.3.0-5)
[2007-11-08 00:06] upgraded xorg-server (1.2.0-5 -> 1.4-4)

Before the upgrade, I was able to use both the touchpad and the mouse at the same time, using the following xorg.conf settings:

Section "ServerLayout"
    InputDevice    "Touchpad" "CorePointer"
    InputDevice "USB Mouse"  "AlwaysCore"
.....

Section "InputDevice"
        Identifier      "USB Mouse"
        Driver          "mouse"
        Option          "Device"                "/dev/input/mice"
    Option        "SendCoreEvents"    "true"
        Option          "Protocol"              "IMPS/2"
        .....
EndSection

Section "InputDevice"
      Identifier    "Touchpad"
      Driver        "synaptics"
      Option        "Device"        "/dev/psaux"
      Option        "Protocol"      "auto-dev"
    .......
EndSection

After the upgrade, the touchpad was still working with these settings but the mouse wasn't.  I then changed the xorg.conf settings as follows:

Section "ServerLayout"
    InputDevice    "USB Mouse" "CorePointer"
    InputDevice "Touchpad"  "AlwaysCore"

with the InputDevice sections remaining the same for USB Mouse and Touchpad.  After this change the mouse was working but the touchpad wasn't.  Finally, I changed the xorg.conf settings as follows:

Section "ServerLayout"
    InputDevice    "Touchpad" "CorePointer"
    InputDevice    "USBMouse" "SendCoreEvents"

with the InputDevice sections remaining the same for USB Mouse and Touchpad.  This didn't change anything from the last setting: the mouse was working but the touchpad wasn't.

How can I restore the ability to simultaneously use mouse and touchpad?

Same here, I had to downgrade the synaptics package to make it work again:

pacman -U /var/cache/pacman/pkg/synaptics-0.14.6-2.pkg.tar.gz

Don't panic!

Re: [Fixed?] Cannot use mouse and touchpad at the same time after upgrade

I'm having the same issue on a Dell E1705 laptop.

I wished I could help you fixing this but I can't.  For me this problem suddenly cleared up without my changing anything in the last version of xorg.conf that I posted above.  Now I can use mouse and touchpad at the same time again.  I've got no idea how this problem cleared up, didn't install or upgrade any software.

Re: [Fixed?] Cannot use mouse and touchpad at the same time after upgrade

Try this:

Move "SendCoreEvents" to the Touchpad line (replacing the "AlwaysCore" bit) and then comment out the USB mouse.  So in the end, it'll look like this:

Section "ServerLayout"
    InputDevice    "Touchpad" "SendCoreEvents"
#    InputDevice    "USBMouse" 
EndSection

Restart X and see if everything is working right.

PS: You may also want to consider changing the Touchpad device line to "/dev/input/mouse2" instead of "/dev/psaux" as I believe psaux has been deprecated in kernel 2.6.  I could be wrong, but I can tell you that /dev/input/mouse2 works great with the touchpad on my Dell e1505.
