--- Comment #9 from Sandeep <sandy.8925 at gmail.com> --- I booted Linux 3.13.6 with the drm.debug=4 parameter - it looks like the internal LVDS output is set to use a different CRTC than the HDMI output, even in clone mode. The LVDS monitor's backlight is also off, it does not switch on at all or get enabled after suspend and resume. Only a full system restart will bring it back to life. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
