aexl, as per http://support.lenovo.com/us/en/products/Laptops-and- netbooks/ThinkPad-L-Series- laptops/ThinkPad-L540?linkTrack=Homepage:Body_Search%20Products an update to your computer's buggy and outdated BIOS is available (1.82). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status New. If it's not reproducible, please mark this as Invalid. Thank you for your understanding. ** Attachment removed: "ProcInterrupts.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547744/+files/ProcInterrupts.txt ** Attachment removed: "MonitorsUser.xml.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547741/+files/MonitorsUser.xml.txt ** Attachment removed: "ProcCpuinfo.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547742/+files/ProcCpuinfo.txt ** Attachment removed: "ProcEnviron.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547743/+files/ProcEnviron.txt ** Attachment removed: "Lsusb.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547740/+files/Lsusb.txt ** Attachment removed: "Lspci.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547739/+files/Lspci.txt ** Attachment removed: "LightdmLog.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547738/+files/LightdmLog.txt ** Attachment removed: "LightdmGreeterLogOld.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547737/+files/LightdmGreeterLogOld.txt ** Attachment removed: "LightdmGreeterLog.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547736/+files/LightdmGreeterLog.txt ** Attachment removed: "LightdmDisplayLog.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547735/+files/LightdmDisplayLog.txt ** Attachment removed: "JournalErrors.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547734/+files/JournalErrors.txt ** Attachment removed: "GconfCompiz.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547733/+files/GconfCompiz.txt ** Attachment removed: "DpkgLog.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547732/+files/DpkgLog.txt ** Attachment removed: "DkmsStatus.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547731/+files/DkmsStatus.txt ** Attachment removed: "Dependencies.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547730/+files/Dependencies.txt ** Attachment removed: "CurrentDmesg.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547729/+files/CurrentDmesg.txt ** Attachment removed: "BootLog.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547728/+files/BootLog.txt ** Attachment removed: "ProcModules.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1530171/+attachment/4547745/+files/ProcModules.txt ** Tags added: wily ** Description changed: - On Thinkpad L540 with intel graphics: - External monitors are not recognized in display settings when plugged into any dock port. They *are* recognized after a reboot (not after logout). After plugging out and the in again they are not recognized. A monitor plugged in and out of the non-dock VGA is recognized instantly. After plugging in or out of the non-dock VGA, monitors plugged to dock ports are recognized (which serves as a crazy workaround for me now). Everything used to work with 14.10, but stopped with 15.04. A recent test with 1510 live CD did not fix this. - --- + --- .tmp.unity.support.test.0: - + ApportVersion: 2.17.2-0ubuntu1.8 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity DistUpgraded: 2016-01-04 01:09:49,649 DEBUG enabling apt cron job DistroCodename: vivid DistroRelease: Ubuntu 15.04 DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: -
