Christopher: I still owe the filing of a bug via 'ubuntu-bug linux'. However, there seem to be at least two possilbly related other bugs: 1) the blacking out of the screen while starting the live cd: *patience* seems the "solution" at this moment in time (as detailed below); 2) a system crash shutting down from the live cd; 3) system freeze when trying to detect screens via System Settings > Displays > Detect Displays.
For the present bug, i.e. booting with the 14.04.02 amd64 LTS image (from February 18 (?)), I could observe the following (written here mainly for the sake of owners of a Lenovo w541). After booting with the live cd 14.04.2 LTS amd64 and choosing to try ubuntu, the screen shows ubuntu and the four dots in red and white progressing, then, later, the screen goes blank, then the mouse coursor appears, the screen goes blank again, and finally the system is up and running and one can go through the installation process (which I've completed successfully twice). manadi, Arno or Salvatore, can you confirm? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1437386 Title: Unable to boot LenovoThinkpad W541 Status in linux package in Ubuntu: Incomplete Bug description: I tried to boot my Lenovo Thinkpad W541 using a bootable USB(having Ubuntu 14.04 image). I could see the welcome screen where I can choose to try or install Ubuntu. Choosing either one causes a freeze. Initial boot screen shows the following error (which maybe the reason?): "mmc0 unknown controller version(3), You may experience problems" I cannot run "apport-collect" since this problem stops me from booting. --- ApportVersion: 2.12.5-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: ubuntu 2803 F.... pulseaudio /dev/snd/controlC0: ubuntu 2803 F.... pulseaudio CasperVersion: 1.336ubuntu1 DistroRelease: Ubuntu 13.10 LiveMediaBuild: Ubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) MachineType: LENOVO 20EGS01600 MarkForUpload: True Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: file=/cdrom/preseed/username.seed boot=casper initrd=/casper/initrd.lz quiet splash -- maybe-ubiquity ProcVersionSignature: Ubuntu 3.11.0-12.19-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: 02/26/2015 dmi.bios.vendor: LENOVO dmi.bios.version: GNET72WW (2.20 ) dmi.board.asset.tag: Not Available dmi.board.name: 20EGS01600 dmi.board.vendor: LENOVO dmi.board.version: Not Defined dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrGNET72WW(2.20):bd02/26/2015:svnLENOVO:pn20EGS01600:pvrThinkPadW541:rvnLENOVO:rn20EGS01600:rvrNotDefined:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 20EGS01600 dmi.product.version: ThinkPad W541 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1437386/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
