@biolyasser: I tried installing a fresh copy of Mint/xfce on a spare partition, on my machine it has the same resume problem as every other recent distro version I've tried. The only working versions for me are not recent: Ubuntu 13.04, 13.10 and Debian wheezy.
One interesting thing that may or may not be related: doing "cat /sys/power/state" gives the following: "standby mem disk" on older versions where suspend/resume works "freeze standby mem disk" on versions where suspend/resume is broken -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1283938 Title: Ubuntu 14.04 blank screen after wakeup from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-trusty/+bug/1283938/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
