Diablo III on Ubuntu 11.04

Got Diablo III working on my Ubuntu 11.04 box. Not sure if the below is all necessary, but this is what I have workng now.

Things needed

• Synaptic package manager, search the Ubuntu app store thingy.
• Wine Development Release 1.5+, install instructions here, still ended up using Synaptic to install development release.
• PlayOnLinux, install instuctions for lastest version.
• Diablo III setup directory, copied from windows.

Things to do

1. Start PlayOnLinux
2. Click add program
3. Find Diablo 3
4. Follow PlayOnLinux install instuctions, find Setup.exe in setup directory copied from Windows.
5. Follow Diablo III install instructions
6. Clickng play, and attempting to log on would hang on "Authenticating Credentials."
7. Close Diablo III
8. Run command found on PlayOnLinux forum (found here)
   Console:
   echo 0|sudo tee /proc/sys/kernel/yama/ptrace_scope
9. Run Diablo III again, shouldn't hang on "Authenticating Credentials."

Have had my system hang a couple of times playing so far. Need to look into why.
