Typically input device recognition issues are due to kernel driver
loading issues.

In both the Xorg logs and all three gdm logs you posted it is showing a
Logitech USB optical mouse being recognized, so unfortunately there
isn't an error to go on here.  It's showing up fine in dmesg as well.

Here is how I'd go about debugging the problem if it was my mouse:
First rule out any hardware issues like flaky batteries (it happens!)
and so on.  Then, reboot until you get a boot where it *doesn't* detect
the mouse.  I'd then look at `dmesg` output to see if the mouse is
listed.  There should be a line like this one:

[    3.298428] generic-usb 0003:046D:C50E.0001: input,hidraw0: USB HID
v1.11 Mouse [Logitech USB RECEIVER] on usb-0000:00:02.0-2/input0

If that is missing, then it is definitely a kernel bug.

If it's there, next I'd look at the output of `sudo lsinput` which
should display a listing of kernel-detected devices.  The device should
be shown there.  If not, then probably a kernel bug.

Next, look at the output of xinput list, verify whether the device is
there.  If not, and it was in lsinput and/or dmesg, then it might be an
X bug.  Look through /var/log/Xorg.0.log in this case and see if it is
shown there.  If you get this far, contact us X guys again and we'll
take it from there.
