The AGP driver is required to save and restore relevant register state on such systems; NVIDIA's NvAGP is notified of power management events and ensures its configuration is kept intact across suspend/resume cycles." ** Changed in: nvidia-graphics-drivers-173 (Ubuntu) Status: New => Confirmed -- Hibernate not resuming on PC-Chips M811LU https://bugs.launchpad.net/bugs/255601 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
