The edid from xrandr and read-edid are identical but alternately inverted. Note those edids are different from what I posted originally, although it's connected to the same kvm and monitor.
dmesg is returning this edid now: [166049.859894] 00 ff ff ff ff ff ff 00 4d d9 90 10 01 01 01 01 [166049.859896] 09 0d 01 03 0e 26 1e 8c ea 6f 89 a2 5a 5d 94 24 [166049.859898] 1a 48 4c a1 08 00 81 80 81 40 01 01 03 01 01 01 [166049.859900] 01 01 01 01 11 01 30 2a 00 98 51 00 aa 40 30 70 [166049.859902] 13 00 78 2f 11 00 00 1e 00 00 00 fd 00 37 41 1c [166049.859904] 41 0b 40 0a 20 20 20 20 20 20 00 00 00 fc 00 53 [166049.859906] 44 4d 2d 53 39 31 0a 20 20 20 20 20 00 00 00 ff [166049.859907] 00 34 32 35 39 39 31 33 0a 20 20 20 20 20 00 d3 That matches up to the edid from xrandr, but there's some slight differences: - 090d01030e261e8cea6f89a25a5d9424 # 5 vs 4 +090d01030e261e8cea6f89a25a4d9424 - 1a484ca1080081808140010103010101 # 3 vs 1 +1a484ca1080081808140010101010101 - 010101011101302a00985100aa403070 # a vs 2 +010101010101302a009851002a403070 - 1300782f1100001e000000fd0037411c # f vs d +1300782d1100001e000000fd0037411c - 410b400a202020202020000000fc0053 # 4 vs 0 +410b000a202020202020000000fc0053 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/992346 Title: *ERROR* EDID checksum is invalid, remainder is 161 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/992346/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
