I see now... I DID test the '--quirk-s3-bios' flag, but I need '--quirk- test', which is not documented in the manpage... from pm-utils-1.4.1/README.debugging: "* To override the usual quirk filtering (for kernel modesetting, binary drivers, and exotic hardware), pass --quirk-test along with any other quirks you want to try. This may make your system crash in new and exciting ways by conflicting with the kernel when suspending or resuming, but is very useful for debugging. You have been warned." Oh, well, I'm happy that someone found a solution and shared it with us all :D -- 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
