You can look at the KMS status in /sys/class/drm/ -- you should see cardN-DVI-I-N directories. xrandr should also provide accurate status, e.g.: $ grep . /sys/class/drm/card*-*/status /sys/class/drm/card0-DVI-I-1/status:connected /sys/class/drm/card0-DVI-I-2/status:disconnected However it may end up being hidden due to vgaswitcheroo -- so make sure to look into that too. (Unfortunately I know next to nothing about vgaswitcheroo, but I'm sure Google knows more.)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
