Synaptics Touchpad Freeze (Kernel 3.3.2)

Hi,

After upgrading the kernel to 3.3.2 and synaptics driver to 1.5.99.903 my touchpad freezes after some time. It is temporarily fixed by reloading (rmmod/modprobe) psmouse kernel module. Also, sometimes, it freezes the whole Xorg and I even need to reboot the laptop. I am using the x86_64. Does anybody know anything about this issue?

Regards,
Pedro

Re: Synaptics Touchpad Freeze (Kernel 3.3.2)

I have a (possibly) related problem - my Logitech G510 keyboard gets stuck randomly, necessitating a reboot. Sometimes quickly unplugging the G510 and adding another keyboard allows me to continue working for a while, but the USB subsystem appears to become unstable, necessitating a reboot. This is not an electrical error, as the keyboard works perfectly when plugged into machines running Ubuntu and Windows 7.  Strangly, the mouse and any connected USB storage continues to work just fine, and the machine will reboot gracefully, only the keyboard system becomes flaky.

I managed to capture a dmesg crash log at one point:

Irrelevant parts have been snipped out, but a full log is readable here: http://pastebin.com/iKY1uuSH
This happened with 3.2.12 so frequently I had to switch to another keyboard (Saitek Eclipse), and if I recall correctly, it never happened with that. With kernels 3.3.1 and 3.3.2 the G510 has caused one crash, so some improvement has happened.

My motherboard is an ASUS M4N78 Pro (AM2+ socket, nVidia chipset), with the latest BIOS as of 10.3.2012, with a Phenom II x4 965 CPU.

Re: Synaptics Touchpad Freeze (Kernel 3.3.2)

Hi,

The problem you comment is not related. I have no kernel oops, so it is not totally broken. My problem provokes Xorg to explode and GDM to restart, so every application is closed without chance and it is very annoying . As I said, the problem should be in Kernel 3.3.2 or the latest version of Synaptics driver. I will try to downgrade synaptics and see if it is fixed.

Regards,
Pedro
