My computer is an Acer S7 laptop with intel HD4000 graphics. I am booting in EFI mode, and the computer successfully boots because I can hear the Ubuntu volume change sounds when I hit the volume up/down buttons, and when I then attach an external HDMI monitor I can see a desktop. The backlight on the internal display is on (I can see it glowing) but the internal screen is completely blank. Using the hotkey I can turn the backlight on/off. "Settings/Displays" shows "Built-in Display" as active and positioned next to external HDMI monitor. If I boot in legacy mode, the internal display works. I have previously installed Ubuntu 13.04 on the same laptop in EFI mode without issues. Strangely the internal display is not detected as LVDS, as xrandr gives this output: ubuntu@ubuntu:~$ xrandr Screen 0: minimum 320 x 200, current 3840 x 1080, maximum 32767 x 32767 eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 256mm x 144mm 1920x1080 60.0*+ 59.9 1680x1050 60.0 59.9 1600x1024 60.2 1400x1050 60.0 1280x1024 60.0 1440x900 59.9 1280x960 60.0 1360x768 59.8 60.0 1152x864 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 521mm x 293mm 1920x1080 60.0*+ 50.0 59.9 1920x1080i 60.1 50.0 60.0 1680x1050 59.9 1280x1024 75.0 60.0 1440x900 59.9 1280x960 60.0 1152x864 75.0 1280x720 60.0 50.0 59.9 1440x576 50.0 1024x768 75.1 70.1 60.0 1440x480 60.0 59.9 832x624 74.6 800x600 72.2 75.0 60.3 56.2 720x576 50.0 720x480 60.0 59.9 640x480 75.0 72.8 66.7 60.0 59.9 720x400 70.1 DP1 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis) --- ApportVersion: 2.12.5-0ubuntu1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ubuntu 2896 F.... pulseaudio CasperVersion: 1.336ubuntu1 DistroRelease: Ubuntu 13.10 LiveMediaBuild: Ubuntu 13.10 "Saucy Salamander" - Beta amd64 (20131009) MachineType: Acer Aspire S7-191 MarkForUpload: True Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/casper/vmlinuz.efi file=/cdrom/preseed/username.seed boot=casper quiet splash -- ProcVersionSignature: Ubuntu 3.11.0-12.18-generic 3.11.3 RelatedPackageVersions: linux-restricted-modules-3.11.0-12-generic N/A linux-backports-modules-3.11.0-12-generic N/A linux-firmware 1.116 Tags: saucy Uname: Linux 3.11.0-12-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo dmi.bios.date: 11/16/2012 dmi.bios.vendor: Insyde Corp. dmi.bios.version: V2.09 dmi.board.asset.tag: No Asset Tag dmi.board.name: Helium dmi.board.vendor: Acer dmi.board.version: V2.09 dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: Acer dmi.chassis.version: V2.09 dmi.modalias: dmi:bvnInsydeCorp.:bvrV2.09:bd11/16/2012:svnAcer:pnAspireS7-191:pvrV2.09:rvnAcer:rnHelium:rvrV2.09:cvnAcer:ct10:cvrV2.09: dmi.product.name: Aspire S7-191 dmi.product.version: V2.09 dmi.sys.vendor: Acer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1237479/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
