Comment # 5 on bug 936974 from Egbert Eich

THis is actually the result of running X non-root:

[    97.392] (II) Using input driver 'vmmouse' for 'ImPS/2 Generic Wheel Mouse'
[    97.392] (**) ImPS/2 Generic Wheel Mouse: always reports core events
[    97.392] xf86EnableIOPorts: failed to set IOPL for I/O (Operation not
permitted)
[    97.392] (EE) PreInit returned 2 for "ImPS/2 Generic Wheel Mouse"
[    97.392] (II) VMWARE(0): VMMouseUnInit

This has been a specialty of gdm. Not sure if this has been fixed for
Tumbleweed meanwhile. 
Assigning to Gnome.
