I removed the nvidia drivers coming with the distro, and installed the latest 64bit drivers from the Nvidia website (270.41.06) just in case. Problem still persists.
I then removed those drivers, and installed the nouveau driver via apt. Problem still persists. Sumary: This problem does not seem to be directly related to the GPU drivers. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in Ubuntu. https://bugs.launchpad.net/bugs/776999 Title: Lenovo W520 laptop freezes on ACPI-related actions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
