Source: xserver-xorg-input-libinput Version: 0.18.0-1 Severity: normal I'm filing this as "normal" severity, since I'm not sure how common my installation setup is (how many people have mice vs. slick multitouch touchpads), but personally this is "important" or higher -- I have uninstalled this package because it removes basic capabilities from my hardware.
The libinput driver seems to be replacing the synaptics driver, but it does not match it in functionality: * The pointer acceleration tracking is far worse than the synaptics driver. I was able to trivially adjust the pointer speed settings for the synaptics driver so that I can have fine grained pointer control and also be able to quickly move the pointer from one side of the screen to the other. After the libinput driver installed, I have no more control over acceleration, and have had to turn down the pointer speed lest it fly all over the screen, and so now it's hard to get the pointer across the screen in a single swipe across my LARGE touchpad. * Multi-finger click for secondary buttons is gone. Apparently the libinput folks decided that this feature should be disabled unless your touchpad says it comes from Apple. Because NOBODY ELSE ever wants this feature or had it turned on before ... oh ... wait ... *sigh*. Granted, there is a way to bring this back via mucking in dconf, but it disabled a common feature for no apparent reason with no notice and provides no UI to get it back. * Inertial scrolling is gone, and there's no hidden setting for this. Apparently the synaptics driver had a corner case issue where the scrolling wouldn't stop when you started typing ... so they just deleted the entire inertial scrolling feature and decided it was someone else's job to implement it ... and nobody has. Who knows if they ever will? To sum it up, this "upgrade" damages pointer motion, clicking, and scrolling. Since we don't have the fancier multitouch gesture support out of the box in Linux yet, that means 100% of the things I can do with my touchpad got noticeably worse. Until this input driver covers the core features of what it's replacing, it doesn't seem right to have it be the default driver for these types of devices. -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (990, 'testing'), (500, 'buildd-unstable'), (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.5.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system)
