Has anyone tried adding radeon.dpm=1 to your grub? Try: edit /etc/default/grub and add the 'radeon.dpm=1' to the GRUB_CMDLINE_LINUX_DEFAULT line, so it would look something like:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.dpm=1" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1304912 Title: Ubuntu 14.04 laptop uses lot of power switchable graphics To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1304912/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
