Re: Radeon M7 and resuming from suspend-to-ram

[Jeremy Moles <jeremy-9vekgGPT+OA7YuNMryXyOw@public.gmane.org>]

Probably already tried this but:

Here at work we use an ACPID script that simply runs "radeontool light
on" after a resume. Also, you might trying "chvt 1" or similar before
suspend and chvt'ing back to whatever TTY X is on upon resume.

That's worked sometimes too.
