Mark, as per http://support.lenovo.com/us/en/products/laptops-and- netbooks/lenovo-b-series-laptops/lenovo-b50-70-notebook an update to your computer's buggy and outdated BIOS is available (2.08). 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, and the information above is provided, then please mark this report Status Confirmed. Thank you for your understanding. ** Tags removed: kernel-unable-to-test-upstream lenovo touchpad ** Tags added: bios-outdated-2.08 needs-upstream-testing ** Attachment removed: "lspci" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1423704/+attachment/4322802/+files/lspci-vnvn.log ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1423704 Title: Elantech touchpad without multi-touch Ubuntu 14.04.1 Status in linux package in Ubuntu: Incomplete Bug description: On my Lenovo B50-70 laptop there is a Elantech touchpad installed. It is working perfectly as a mouse but scrolling, multi-touch, 2 finger gestures are not working. Many people are reporting this for older kernels. I would like to report this for: Ubuntu 14.04.1 LTS. Kernel: 3.13.0-45-generic #74-Ubuntu SMP Tue Jan 13 19:36:28 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Ubuntu 3.13.0-45.74-generic 3.13.11-ckt13 There are many workarounds posted like the one below. It is a kind of bypass using dkms and dynamically add a module. Some users reporting that the dynamic module does not survive a reboot. This is "fixed" by adding the remove of the psmouse and adding the new psmouse module. The code seems to work perfectly, never the less. I am wondering if there is a permanent solution in one of the next kernel and would like to provide you information. In ubuntu 14.10 (32 bit) it is working. == Dynamic fix using dkms == See bug: 1166442 Code: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1166442/+attachment/3941591/+files /psmouse-elantech-x551c.tar.gz == data == I looked on the ubuntu store and found: gpointing-device-settings 1.5.1-6ubuntu2 It has selection boxes for emulation of horizontal/vertical scrolling but it is not working.
