Thomas, I had the post-suspend graphics trouble on that same hardware in
the previous version of Ubuntu. In my case, it was a hyperthreading
problem and I solved it by creating a new file in /etc/pm/sleep.d that
looks like this:
#!/bin/sh
case $1 in
hibernate|suspend)
echo 0 > /sys/devices/system/cpu/cpu1/online
echo 0 > /sys/devices/system/cpu/cpu3/online
echo 0 > /sys/devices/system/cpu/cpu5/online
echo 0 > /sys/devices/system/cpu/cpu7/online
;;
thaw|resume)
echo 1 > /sys/devices/system/cpu/cpu1/online
echo 1 > /sys/devices/system/cpu/cpu3/online
echo 1 > /sys/devices/system/cpu/cpu5/online
echo 1 > /sys/devices/system/cpu/cpu7/online
;;
esac
