Confirming this on a desktop machine, Intel(R) Core(TM) i5-2500K with built-in Intel graphics and no additional video card at all.
Suspend/resume was working just fine on 13.10. After upgrade to 14.04 suspend still works, but upon resume the screen is blank. The only way to get it back is to go to a text console and force-kill X so it respawns. I'm running KDE as my desktop, in case it matters. -- 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/xserver-xorg-video-ati/+bug/1283938/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
