+I'd say it probably is.  I use gnome, and with the conversion to gnome 3 
+(which started in 2.x), suspend/hibernate is among the things that no 
+longer work properly for me.
+
+First, note that my computer display is in French, so the English 
+translation may be approximate.  (And you wouldn't want to see my 
+attempts at Spanish.)
+
+Run gnome-power-preferences (from console),
+or from the preferences menu select "power management preferences"
+
+Find the line, "Suspend computer if inactive since:", and set the value 
+to "Never"
+(Alternives are 10 min, 30 min, 1 h, 2 h if you have the right place.)
+
+There is a checkbox for "shut down the hard disks if possible".
+If you still have problems, you probably want to uncheck that.
+However on my system it never shuts down the disks, even if checked.
+
+There is also a line to "Suspend the screen if inactive since:"
+I had to set this to "Never" to avoid the screen turning off 
+permanently, forcing me to do a hard reboot to see the screen again.
+So if you have similar problems, try that.
+However, if it works without problems, it will make your monitor last a 
+lot longer.
+(I had a client in the past who tested this.  It made a considerable 
+difference.)
+
