Invisible Mouse Pointer After Suspend
 
On a Panasonic CF-29 running Debian Etch (mostly), after suspending the system to RAM then waking it up, the mouse pointer becomes invisible. The pointer is still functional despite being invisible. This problem has persisted across several kernel versions (2.6.17 - 2.6.21-rc7) and software upgrades. I am not sure when it started, because I did not use suspend for some time after I set up the system. When the problem first occurred, a logout/login would fix it. But now I can find nothing short of a reboot that restores the pointer. I'm using KDE and kdm. Selecting "Restart X server" from the kdm menu by command does not fix it, nor does restarting kdm by command after dropping to a text-mode login.
What process is controlling the mouse?

Have you tried
Code:

Section "Device"
...
  Option "HWCursor" "off"

in your /etc/X11/xorg.conf (or whatever your x conf file is called...) ?

(This is a known issues with NVIDIA cards ... but could resolve your problem also with another card...)

Cheers, Tom.

Fujitsu lifebook with i810 graphics
 
Had the same effect on the fujistu-siemens lifebook T4010 (UK model) - 'echo mem > /sys/power/state' suspends to ram, but I get an invisible pointer on un-suspending.

With the i810 (855GM) Intel graphics, the required solution is:

Option "SWCursor" "true"

in the /etc/X11/xorg.conf i810 section

HTH

That's a winner!

To clarify, here is the working section:
Code:

Section "Device"
        Identifier        "Intel Corporation 82852/855GM Integrated Graphics Device"
        Driver                "i810"
        BusID                "PCI:0:2:0" # YMMV!
        Option "HWCursor" "off"    # Not sure if this is required.
        Option "SWCursor" "on"
EndSection

It surely would make many people's lives easier if the xorg.conf option switches were documented somewhere.
