I was able to fix this by editing my grub settings. http://askubuntu.com/questions/162409/brightness-not-working-on-an-hp- pavilion-dv6-with-a-ati-radeon-hd6770m
The file i edit is /etc/default/grub Before fix (when it didnt work) GRUB_CMLINE_LINUX_DEFAULT="quiet splash nomodeset" The reason I had added nomodeset was to get my virtual consoles to show up when i hit ctrl alt f3 After fix - (suspend works properly again) GRUB_CMDLINE_LINUX_DEFAULT="acpi_backlight=vendor" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1628725 Title: Ubuntu 16.04 blank screen after wakeup from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1628725/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
