Sorry Christopher, I misread and by the time I read it correctly, apport already sent the data.
I just unplugged and replugged the monitor on the front VGA. Then waited a few seconds and plugged the monitor to the back VGA connector. dmesg shows the following information: [ 6613.913005] [drm:drm_edid_block_valid [drm]] *ERROR* EDID checksum is invalid, remainder is 92 [ 6613.913151] Raw EDID: [ 6613.913183] 00 ff ff ff ff ff ff 00 10 ac 07 a0 4c 4b 34 30 [ 6613.913255] 04 0f 01 03 0e 29 1f ff ff ff ff ff ff ff ff ff [ 6613.913333] ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 6613.913405] ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 6613.913484] ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 6613.913562] ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 6613.913633] ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 6613.913711] ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 6613.914978] [drm:radeon_vga_detect [radeon]] *ERROR* VGA-2: probed a monitor but no|invalid EDID -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1565679 Title: No console/display output after boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1565679/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
