Rene Greuel, thank you for reporting this and helping make Ubuntu better. As per http://support.lenovo.com/us/en/products/laptops-and- netbooks/thinkpad-s-series-laptops/thinkpad-s430 an update to your computer's buggy and outdated BIOS is available (2.61). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 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, and the information above is provided, then please mark this report Status Confirmed. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-2.61 ** Changed in: xorg (Ubuntu) Importance: Undecided => Low ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1504220 Title: Black screen after "prime-select nvidia" and restart of lightdm/reboot Status in xorg package in Ubuntu: Incomplete Bug description: I'm using a Lenovo laptop with an intel/nvidia Optimus compatible graphics solution. While being able to use prime-select to switch between those cards with Ubuntu 14.X and official nvidia driversit stopped working when switching to ubuntu 15.04 and newer drivers. I'm not sure when the problem first arises, but I'm stucking with it for almost 5 month. In the meanwhile I stumbled upon errors in xorg.log pointing to insufficient permissions related to DRM and intel driver. I switched to a newer kernel 4.1.x and the xorg.log error had gone, but the general problem remains. A month ago I switched to a wily daily build to test if the bug still exists there. I did a fresh install but the problem is still the same.
