I did some further testing of using pm_suspend from tty1. I noted that the same behaviour occurred... that is that on the first, or second attempt resuming worked... but then on subsequent attempts it did not work, with the whole display going white, and then bleeding to black.
Noting this, I then tried simply running the following, repeated: # vbetool dpms off; sleep 10; vbetool dpms on On the fourth iteration the screen went white and bled to black. Further iterations did not restore the screen. The system was still responding fully.... I initiated a shutdown by pressing the power key. -- Screen shows grey bars after resuming from suspend https://bugs.launchpad.net/bugs/568005 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
