With latest updates and so forth, switching user is not an issue,
suspend/sleep (low power mode with RAM still powered) has no problems. I
believe that hibernate is ok for me. I will, when next the laptop is
free (the lady is powering through course work), try to work out exactly
how to course this
I first started getting this bug when I upgraded to 9.10 but there must
have been an update somewhere along the lines that has sorted this out,
at least for me. Either that, or I simply have managed to dodge this bug
for a long time.
