gnome under xen: mouse pointer invisible

Hi all,

My situation:

  • dom0, opensuse 12.2 64its, udated
  • domU, opensuse 12.2 64bits, updated

Both dom0 and domU are running gnome. The mouse pointer is invisible in domU though the click is possible but very difficult to locate, not really usable. With Icewm or KDE or xfce, the mouse pointer is visible (slow with KDE). I googled a lot but found nothing relevant.
OK with Debian 6.06, but it is Gnome 2.3.
Maybe someone here has a solution?

Thanks in advance
