    So high resolution scrolling still hasn't arrived in user-space yet? That's good to know. I was considering buying one of those high resolution mice, but I don't really like the choices. However, it appears that the high resolution support is hard-coded into the kernel on a per-device basis, so it might not be a good idea to wait for the release of some new mouse.

    When you move from using Linux on a laptop to using Linux on a desktop, the scrollwheel is just awful. Especially without autoscroll. I'm really hoping that high resolution scrolling will fix that.
    I have been using it for years. It requires solaar and manually configuring xinput. The problem is making it automatic.

    The 2nd gen is supposed to be supported as well starting with Linux 5.0: https://www.phoronix.com/scan.php?pa...-2-Linux-Queue
    I didn't even think of using Apple's touchpad. It looks like it would work in Linux. The only problem is that the desktop is where I occasionally boot into Windows, and it looks like you have to install some 3rd party driver to make it work there.

    Was the mouse wheel always slow after updating to kernel 5.0? For me it was normal and then suddenly becomes slow... not quite sure what the cause is. Maybe waking up after power saving idling.

    Even in kernel 4.20, solaar shows the "Wheel Resolution" option. "On" makes a big difference in scrolling speed/smoothness. Not sure if that option was there before. "Off" is the normal behavior I'm used to. The slow scrolling in 5.0 is far slower than the "Off" setting.

    I'll look into these settings next time I boot into 5.0. Thanks again!
    Kernel 4.20 - mouse wheel was always working OK - no sleep/unsleep/reboot/USB re-connect/etc. needed.

    The slowness started immediately after update and reboot to kernel 5.0 (but there was plenty of other packages also updated). I did not try PC sleep/USB reconnect/etc. - I immediately started solaar and changed option "Wheel Resolution" to "On" and it solved issue permanently.

    Now mouse wheel is working always OK - also after PC sleep/wake up or fresh reboot (no need to start solaar manually).

    I haven't tried the current model yet though, only the previous one.

    I don't even understand why would one need high resolution scroll wheel.

    I switched to Wayland again yesterday to check progress on Sway WM. Sway is really good but there are some big quirks depending on software you need.

    X based software like scrot, gcolor3 have to be replaced by grim and other counterparts, wine app dialogs glitch out on resize and app menus don't even show up :\, clipboard is inconcsistent but maybe that may just mean urxvt is X only, I tried to replace with Termite but there was a font horizontal spacing issue.

    Anyways, it's encouraging to see developments and progress but for some workflows it really is going to have some show stoppers for a while that need to be worked out.

    I own a Logitech T650 and I can recommend it.
    Opaque glass surface so you slide well, although it is cold to the touch, like a tablet (you may or may not like this), and is obviously more fragile than the average plastic touchpad.

    It is detected as a touchpad here on OpenSUSE Tumbleweed with KDE (I can see it unlocks the "touchpad" settings panel).
    It scrolls smoothly like a touchpad would, I can change touchpad settings and they actually do something.
    Two-finger scrolling works fine both horizontal and vertical, can reverse the direction like a Mac.
    Single finger, double finger, and three finger tapping works.
    Edge scrolling does not seem to work anywhere near reliably, but I never liked it anyway so no big loss imho.

    While the glass surface is as big as the whole upper surface, the actual touchpad surface ends at 0.5cm from the border on three sides, and on the "up" side (the one with the logitech logo) it ends 1 cm from the actual border. I don't usually notice this when using it, it's pretty big as it is, just for the sake of being though in this mini-review.

    It is using a Unifying dongle like many of higher-end wireless Logitech devices, which means that if you lose the USB dongle you can buy a new one from china or Logitech themselves and just pair it again, plus you can pair other 5 additional Unifying devices (keyboard/mices) to the same USB dongle. This can be done on Linux too through Solaar application, and they are also supported by LFVS firmware updates on Linux.

    I don't know if you need this if you use it only on Linux, but to use it like a touchpad on Windows you need to update its firmware https://support.logitech.com/en_us/p...#windowsPnlBar

    On windows it is complete garbage without this firmware update as the factory firmware basically lacks any multi-touch functionality. I bought it only AFTER this update appeared, and I updated mine straight away.
    Good to know it works well on Linux. But since is not produced anymore (or at last is not on Logitech's website), some sellers are asking a lot of money for one. So is good to keep a eye on Ebay till something new and cheap appears.

    If you miss a touchpad, is still possible using one on a desktop. There are some models, like the Logitech T650 or this Lenovo:

    Cannot say its guaranteed both work on Linux, but a internet search can answer that.

    It depends of distribution and hardware but in my case (Fedora 29 + Logitech MX Master) Solaar probably resolved issue.

    Probably, because I'm not sure - I installed Solaar (sudo dnf install solaar) and tested it months ago and until recent update to kernel 5.0 everything was OK...

    After update to 5.0 - mouse wheel started to work ridiculously slow.

    I started solaar and I changed "Wheel Resolution" option from "Off" to "On". Rest of the settings I left unchanged (probably...) :

    High Resolution Wheel Invert: Off
    Wheel Resolution: On
    dpi: 1000
    Smart Shift: 16

    Now mouse wheel is working OK on Fedora with kernel 5.0. So if you have Logitech mouse - you should try solaar.
    Thanks for the reminder about solaar! I have it installed but haven't launched it in a while. I'm also on Fedora 29 and using a Logitech M720.

    Was the mouse wheel always slow after updating to kernel 5.0? For me it was normal and then suddenly becomes slow... not quite sure what the cause is. Maybe waking up after power saving idling.

    I'll look into these settings next time I boot into 5.0. Thanks again!

They use some bad material for the touchpad surface that your finger doesn't slide smoothly on. And also, it presents itself to the computer as a mouse rather than a touchpad, just like every desktop touchpad I've ever seen. So if you try to scroll with it, the page jumps line by line like it would with a mouse.
    Apple's touchpad works fine/like a touchpad.
    I haven't tried the current model yet though, only the previous one.
