Try i915.enable_fbc=1. But be warned that fbc is still broken AFAIK, so you might get missing screen updates or lockups etc. For working FBC you may want to check out my branch here: <a href="https://gitorious.org/vsyrjala/linux.git">https://gitorious.org/vsyrjala/linux.git</a> fbc_update_thing_14 But the branch is rather old, and doesn't seem anything from there will ever get merged, so it's a bit of dead end at this point. I'm still running that on my IVB laptop simply because I want working FBC and doesn't look like upstream is getting there any time soon.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
