The hints to disable "light locker" presumably refer to Xfce, i.e. are not workarounds on the default Unity, where the machine crashes on resume in spite of all equivalents turned off in the attached settings (and locking up without even permitting Ctrl-Alt-F1 or -Del).
3 apport crash reports for an HP "dc7800p" (with package nvidia-331) have been submitted within the past 30 minutes, but since no reference is displayed (no "bug filing page" displayed after upload, contrary to https://wiki.ubuntu.com/Apport#What_does_it_look_like_for_users.3F), someone else will have to dig them up wherever they have gone, and attach them to this bug. ** Attachment added: "Screenshot from 2014-04-26 18:00:54.png" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1283938/+attachment/4097700/+files/Screenshot%20from%202014-04-26%2018%3A00%3A54.png -- 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
