@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 Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
