Mouse looses sync - X Restart seems only restore option

Bug Description

Release: Ubuntu 8.10 (intrepid)
Gnome: 2.24.1 (Ubuntu 2008-10-24)
Kernel: 2.6.27-11-generic (#1 SMP Thu Jan 29 19:28:32 UTC 2009)
CPU: AMD Turion(tm) 64 X2 Mobile Technology TL-56

At completely random times, the mouse looses sync, and fails to recover. This affects only the *click* functions, not pointer visibility or travel. I've seen reports, in various Linux flavors, with errors of psmouse.c losing sync, but haven't found any specifically talking about a loss of click functionality.

I've attached a log dump of all /var/log files containing the string 'mouse'. You can see where the driver is frequently losing/restoring sync. At some point, it simply loses sync, and fails to restore.

I've tried to tie this to specific actions, CPU loads or high memory utilization, but thus far, it's seemed random, in that it's not tied to any specific action or application I've noticed. However, it does only seem to occur, when there are user-initiated active processes going on. If the machine is idle and processing normally, things are fine.

This is an HP Pavilion DV9320US. Ubuntu 8.10 is the only release to be installed to this machine, so I cannot say if prior releases had this problem. This has been an ongoing problem since the OS was installed, in Nov/Dec time-frame.

Problem *seems* to be tied to a kernel issue, as seen in these log entries, which is an example of the sync loss, requiring either a reboot or X restart:

syslog.0:Feb 4 00:30:27 Megatron kernel: [11315.129813] psmouse.c: TouchPad at isa0060/serio1/input0 lost sync at byte 4

Xinerama causes that, try TwinView.

Twinview originally gave me X-config problems (nVidia w/laptop + external monitor) when I 1st installed, and Xinerama provided a better solution.
So I avoided it. For whatever reason, Twinview is operating correctly now, and not experiencing the resolution issues I originally had.

I made the switch 2 days ago, and thus far, have not had any problems. It also has the added bonus, of allowing Compiz to work, whereas before,
any attempt under Xinerama would reject the options of using any visual effects setting, other than 'none'. I assumed this was due to different
resolutions on 2 screens, as it worked fine in single-monitor mode.

I'm reasonably certain that this resolves the mouse-click problem, but will update you in a couple of days, to confirm.

Thanks for the assist. I hadn't considered any graphics related causes.

The cause is a xinerama vs mouse cursor issue.
when you switch to "twinview", you stopped using xinerama, so the
problem goes away.
