+**This is only valid if you have an ubutu version older than 12.04 or if your 12.04 does not have the most recent updates. with the curren updates (August 1st 2013) the usb suspend fix is not working anymore and therefore breaks suspend once again. at least with 13.04 the usb ports suspend correctly without any further modifications, so you can skip this and only do the suspend fix for the nvidia card (see "ubuntu >= 12.04")**
 the other annoying thing is that suspend is not working correctly.. luckily the same article as above provides a fix for that too:
 create a script that will disable the usb ports and re-enable the nvidia card prior to suspending the computer.. the nvidia card needs to be re-enabled because otherwhise it will become impossible to switch it off again after two resumes..

-**NOTE** right now it is not necessary to disable the USB 3.0 Port too because it is not working anyways.. but maybe in the future it might be necessary to add it to the busses too:
-  BUSES="0000:00:1a.0 0000:00:1d.0 0000:07:00.0"
 now make the file executable:
   sudo chmod 755 /etc/pm/sleep.d/20_custom-asus-pro36jc
+===== fix suspend ubuntu >= 12.04 =====
+haven't tested this with the current updated version of 12.04 or 12.10 but with 13.04 usb suspend works out of the box. so the only thing that's needed to do now is to turn the nvidia card on before supsend and turn it off after supsend in order not to run into any problems on resuming.. maybe that's not even necessary anymore, but i did it anyway :)
+so the above /etc/pm/sleep.d/20_custom-asus-pro36jc file should only contain this script:
+<code>
+#!/bin/sh
+case "${1}" in
+    hibernate|suspend)
+        # Switch nvidia card on before going to sleep, avoids the "constant on"
+        # bug that occurs after 2 suspend/resume cycles (thanks kos888)
+        echo '\_SB.PCI0.PEG1.GFX0._ON' > /proc/acpi/call
+        ;;
+    resume|thaw)
+        echo '\_SB.PCI0.PEG1.GFX0._OFF' > /proc/acpi/call
+        ;;
+esac
+</code>
+make it executable as described above and you are good to go..
