--- Comment #12 from Alex Deucher <alexdeucher at gmail.com> --- (In reply to maxis11 from comment #6) > BTW runpm works with 3.12.7 and 3.12.8 (with 3.13 and later runpm=1 freezes > laptop during boot) runpm support didn't exist until 3.13. If "echo OFF > /sys/kernel/debug/vgaswitcheroo/switch" has never worked, then your system has never had functional support for turning on/off the dGPU. -- You are receiving this mail because: You are watching the assignee of the bug.
