Sitsofe,

I experience this problem in Oneiric:

cat /proc/version
Linux version 3.0.0-19-generic (buildd@vernadsky) (gcc version 4.6.1 (Ubuntu/Linaro 4.6.1-9ubuntu3) ) #33-Ubuntu SMP Thu Apr 19 19:05:57 UTC 2012

cat /proc/version

I can easily reproduce the problem instantly after boot when running bonnie++ benchmarks while switching between multiple X servers via Ctrl/Alt F7-F12, given the following lightdm config (I am logged into one session and the other sessions just show the greeter):

cat /etc/lightdm/lightdm.conf

[LightDM]
greeter-user=lightdm
seats=Seat:0 Seat:1 Seat:2 Seat:3

[SeatDefaults]
allow-guest=false
greeter-hide-users=true
greeter-session=lightdm-gtk-greeter
user-session=xubuntu

[Seat:0]
user-session=xubuntu
autologin-user=

[Seat:1]
user-session=xubuntu
autologin-user=

[Seat:2]
user-session=xubuntu
autologin-user=

[Seat:3]
user-session=xubuntu
autologin-user=

[Seat:4]
user-session=xubuntu
autologin-user=

[Seat:5]
user-session=xubuntu
autologin-user=

[XDMCPServer]
enabled=true

In case I swapoff -a before starting the test, then the problem seems to be gone though.
