I have installed Trusty Tahr hoping that I wouldn't bump into the suspend issue. I had 12.04 installed before but there was no problem with suspend behaviour. then upgraded to 13.10 which was the first time I came across this issue.
After waking from suspend everything freezes on the login scree...
I have Ubuntu desktop installed. Every time update-manager runs it fails:
