But the monitor now defaults to 30 hz refresh rate, although it is still possible to switch it to 60hz through xrandr (but it's a small annoyance).</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>
