Bug Description

The touchpad/appletouch seems to be responding.
If the mouse is over a window after resume, the window receives clicks, and scrolls up and down when using two fingers, but the cursor itself is immovable/frozen/does not move.

Restarting X does not solve the problem.

No obvious errors relating to this are visible in the log.

This worked on ubuntu 8.04 hardy heron.

This error has been observed on ubuntu 8.10 Intrepid Ibex on a MacBook 2,1 C2D.
2.6.27-7-generic #1 SMP Thu Oct 30 04:12:22 UTC 2008 x86_64 GNU/Linux

After resume, performing:
modprobe -r appletouch
modprobe appletouch

restores the pointer to a functioning state.

Yes. It is very annoying.

I have seen that logging on as another user after resume can restore cursor movement as well.

Bug #282415 seems to solve this problem for me, although I then see Bug #280290.

Solving Bug #282415 does not solve the frozen cursor problem after all. I just see Bug #280290 sometimes instead of the frozen cursor.

Hi nikolajsheller,

Please attach the output of `lspci -vvnn` too.

I am not sure why lspci has been requested, as the malfunctioning device is a usb device.

I have attached output from both "lspci -vvnn" and "lsusb -v".

Based on comments #5 and #11, seems to be a kernel issue rather than xorg.

Hi Nikolaj,

Care to try the latest pre-release of Jaunty 9.04 (currently Alpha3) which contains a 2.6.28 based kernel - http://cdimage.ubuntu.com/releases/jaunty/ . You should be able to test suspend/resume via a LiveCD. Please let us know your results. Thanks.

I am unable to test this using the live CD.

Jaunty beta 3 does not boot into the desktop.
Jaunty beta 3 boots, shows a brown background with a cursor in X, and nothing else. No login screen, no desktop.

I can't restart X (fn-ctrl-alt-backspace), change into another tty (fn-ctrl-alt-F1 through F10), eject the CD or get any other response from the machine.

The mouse cursor can be moved though...

I can't suspend by closing the lid.
In earlier versions of Ubuntu, suspend on closing of lid was not enabled by default, which is probably why this does not work.

This issue seems to be resolved in the final version of Jaunty.

I think this issue can be closed for jaunty
