I have a similar issue with a samsumg series 3 laptop with "VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] BeaverCreek [Radeon HD 6620G]" and "VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Seymour [Radeon HD 6400M/7400M Series]". after resume an external monitor show the system is still responsive.
BUT I can make the screen turn on after suspend with the next command: sudo pm-suspend --quirk-test --quirk-s3-bios so if you can try and this work maybe we can kick this issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1034002 Title: 1002:9641 [Lenovo ThinkPad E525] Screen black on resume To manage notifications about this bug go to: https://bugs.launchpad.net/dri/+bug/1034002/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
