Public bug reported: This is an SRU request to bring the libinput 1.10.5 microrelease to bionic-updates.
Bionic ships with 1.10.4, but the 1.10.5 microrelease fixes several highly specific issues with Lenovo T440, T450s and X280 and Dell XPS13 L322X laptops. See: https://lists.freedesktop.org/archives/wayland- devel/2018-April/037934.html [Impact] * Users of Dell XPS13 L322X laptops have an almost unusable touchpad out-of-the-box with Bionic. This has been reported in https://bugs.launchpad.net/libinput/+bug/1746740 and fixed upstream in https://bugs.freedesktop.org/show_bug.cgi?id=104990 . * Users of Lenovo T440, T450s and X280 laptops also have suboptimal touchpad experiences. [Test Case] * The issue can be reproduced on any Dell L322X laptop, by booting the Bionic live CD. The touchpad will only work with the slightest touch, any more amount of touch pressure falsely triggers the palm detection and the cursor won't move. * Manually overriding the HWDB with the patches available in https://bugs.freedesktop.org/show_bug.cgi?id=104990 fixes the issue. * These patches have been released in libinput 1.10.5. * With the patched HWDB or latest microrelease, the touchpad works properly out-of-the-box. [Regression Potential] * Regressions are highly unlikely, changes will only affect users with the above mentioned devices. [Other Info] It is worth noting that the Dell XPS13 L322X is from the Sputnik series of "Developer Edition" laptops from Dell, which are supposed to have excellent Ubuntu support and came pre-installed with Ubuntu 12.04 when first released. Every release from 12.04 to 17.10 had perfect out-of- the-box touchpad support, so this bug is a regression. I realise this is because of the change away from synaptics as the input driver, but in terms of user experience presents a serious regression. ** Affects: libinput (Ubuntu) Importance: Undecided Status: New ** Tags: sru -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libinput in Ubuntu. https://bugs.launchpad.net/bugs/1767559 Title: Provide libinput 1.10.5 in bionic-updates to fix specific touchpad and keyboard issues To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libinput/+bug/1767559/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
