I am specifically looking at whether boot-time fbcon after nouveau loads shows up on HDMI, whether X by default shows up on HDMI, and can I get the HDMI output exclusively. On 3.5.2, fbcon is cloned, X by default is cloned, and HDMI exclusive works. On 3.11-rc6, fbcon shows only on LVDS, X by default shows only on LVDS, and HDMI exclusive does not show up anywhere. (off-topic: default resolution was not native for LVDS anymore.) The HDMI exclusive is set up by: $ xrandr --output LVDS-1 --off --output HDMI-1 --mode 1920x1080 --set 'scaling mode' 'None' I did also try dual setup: $ xrandr --output LVDS-1 --auto --output HDMI-1 --mode 1920x1080 --set 'scaling mode' 'None' --right-of LVDS-1 but that does not work even on 3.5.2, LVDS works but TV says no signal. Apparently something in manual dual-screen setup gets messed up, while boot-up dual screen works. But that is off-topic here. Therefore, my bisection will concentrate on whether HDMI exclusive at full-HD resolution works or not.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
