Hi Christopher: I ran apport-collect for you, as described in your message below.
I've tried a number of things to turn the discrete Radeon unit off. I'm currently trying to use "radeon.dpm=0" in the kernel, followed by echo profile > /sys/class/drm/card0/device/power_method echo profile > /sys/class/drm/card1/device/power_method echo low > /sys/class/drm/card0/device/power_profile echo low > /sys/class/drm/card1/device/power_profile echo IGD > /sys/kernel/debug/vgaswitcheroo/switch echo OFF > /sys/kernel/debug/vgaswitcheroo/switch Previously, I've tried "radeon.dpm=1" in the kernel, followed by echo battery > /sys/class/drm/card0/device/power_dpm_state echo battery > /sys/class/drm/card1/device/power_dpm_state I'm willing to try other combinations if can suggest some. Thanks for your help. Henry Baker Santa Barbara, CA At 03:14 PM 10/25/2015, Christopher M.
