However after the boot process is completed and the login prompt should show up, the monitor doesn't display anything anymore (black) - as if there is no input. On dmesg I found the following errors: [ 62.364246] [drm:drm_edid_block_valid [drm]] *ERROR* EDID checksum is invalid, remainder is 34 [ 62.364385] Raw EDID: [ 62.364419] 00 ff ff ff ff ff ff 00 10 ac 07 a0 4c 4b 34 30 [ 62.364494] 04 0f 01 03 0e 29 1f 78 ee 63 90 a3 57 4b 9b 25 [ 62.364575] 11 50 54 a5 4b 00 81 80 a9 40 71 4f 01 01 01 01 [ 62.364655] 01 01 01 01 01 01 48 3f 40 30 62 b0 32 40 40 c0 [ 62.364736] 13 00 6f 13 11 00 00 1e 00 00 00 ff 00 43 30 38 [ 62.364817] 38 31 35 31 49 30 34 4b 4c 20 00 00 00 fc 00 44 [ 62.364892] 45 4c 4c 20 32 30 30 31 46 50 09 ff ff ff ff ff [ 62.364966] ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 62.366200] [drm:radeon_vga_detect [radeon]] *ERROR* VGA-2: probed a monitor but no|invalid EDID [ 62.427863] [drm:drm_edid_block_valid [drm]] *ERROR* EDID checksum is invalid, remainder is 199 [ 62.427991] Raw EDID: [ 62.428038] 00 ff ff ff ff ff ff 00 10 ac 07 a0 4c 4b 34 30 [ 62.428147] 04 0f 01 03 0e 29 1f 78 ee 63 90 a3 57 4b 9b 25 [ 62.428245] 11 50 54 a5 4b 00 81 80 a9 40 71 4f 01 01 01 01 [ 62.428355] 01 01 01 01 01 01 48 3f 40 30 62 b0 32 40 40 c0 [ 62.428444] 13 00 6f 13 11 00 00 1e 00 00 00 ff 00 43 30 38 [ 62.428542] 38 31 35 31 49 30 34 4b 4c 20 00 00 00 fc 00 44 [ 62.428635] 45 4c 4c 20 32 30 30 31 46 ff ff ff ff ff ff ff [ 62.428732] ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff [ 62.429959] [drm:radeon_vga_detect [radeon]] *ERROR* VGA-2: probed a monitor but no|invalid EDID ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: xorg (not installed) ProcVersionSignature: Ubuntu 4.2.0-27.32~14.04.1-generic 4.2.8-ckt1 Uname: Linux 4.2.0-27-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.19 Architecture: amd64 Date: Mon Apr 4 13:03:27 2016 InstallationDate: Installed on 2016-04-04 (0 days ago) InstallationMedia: Ubuntu-Server 14.04.4 LTS "Trusty Tahr" - Release amd64 (20160217.1) SourcePackage: xorg Symptom: display UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1565699/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
