I just switched from Windows 10 to Bazzite with KDE 6. I have experience with linux before, but not as a main OS. I have a Logitech Performance MX. I used SetPoint on Windows to fine-tune things.

For some reason, my scroll wheel acts differently in almost every program. Firefox is the only one that feels normal. My scroll wheel clicks as I scroll, and in Windows that would do 3 lines up or down.

Nothing except Firefox follows the clicking, so all my scrolling is super fine-grained as if I were scrolling with a trachpad. I tried Solaar and that gave me an option to turn off smooth scrolling, but now I need to scroll 6 or more times to see any movement. Increasing sensitivity in KDE just means after 6 times of nothing, the next one is a huge leap. There’s no middle ground it seems and I’m losing my mind trying to fix this.

Is there anything else I can do?

    I had the same issue with the MX Master 3S. It’s caused by the hi-res scroll wheel feature of Logitech’s HID++. If you have a Bolt dongle, try using that instead of Bluetooth.

    If that’s not a fix, try blacklisting the hid-logitech-hidpp kernel module.

    Arch wiki article about module blacklisting: https://wiki.archlinux.org/title/Kernel_module#Blacklisting
    About kernel parameters in GRUB (should be the default bootloader in Bazzite): https://wiki.archlinux.org/title/Kernel_parameters#GRUB

    The easiest way to do it in GRUB is to:

    • open the /etc/default/grub file with root privileges
    • find the line starting with GRUB_CMDLINE_LINUX_DEFAULT=...
    • insert module_blacklist=hid-logitech-hidpp to the end separated by a single space
    • save the file
    • run grub2-mkconfig -o /boot/grub2/grub.cfg as root to apply the changes
    • reboot

    This will prevent loading the HID++ module entirely. The OS then shouldn’t be able to interpret high-res scroll events. You’ll also have to enable or disable the scroll wheel resolution in Solaar to handle it properly.

    (edit) tested in a Bazzite VM and updated the steps.

      I can’t wait to try this when I get home today. I can’t thank you enough for the details. I’ll let you know how it goes later.

      if you have a Bolt dongle, try using that instead of Bluetooth.

      I use the unifying receiver that came with the mouse.

      No dice :/

      This is my original grub file:

      GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true

      I added:

      GRUB_CMDLINE_LINUX_DEFAULT="module_blacklist=hid-logitech-hidpp"

      and that didn’t work.

      I also tried this:

      GRUB_CMDLINE_LINUX="rhgb quiet" "module_blacklist=hid-logitech-hidpp"

      and that didn’t work.

      Either I’m formatting this incorrectly, or my setup is different somehow.

        GRUB_CMDLINE_LINUX="rhgb quiet module_blacklist=hid-logitech-hidpp"

        and don’t forget to run sudo grub2-makecfg -o /boot/grub2/grub.cfg to apply the changes. When you reboot, press e on the GRUB screen to make sure the boot parameters are passed correctly.

          Still not working :/

          I looked at the boot parameters and the blacklist was not on there, so I typed it it and booted and it still didn’t work.

            Hmm… this might break the OS completely, but you could delete the module’s binary files. Can’t load it if it doesn’t exist in the first place.

            Run find /lib/modules -iname '*hidpp*' and move the files it found to a location where you can recover them later if needed, then reboot.

              Hell, this is worth a shot.

              I 'm already shopping around for a new distro because of this. Games are completely unplayable because of the scroll wheel. The tiniest movement will swap weapons, even if I’m not touching the wheel at all.

                If you decide to ditch Bazzite, try either Garuda or EndeavourOS. They’re both Arch-based, which is not something I’d recommend for a beginner, but the rolling release will ensure that you always have the latest software.

                I’ve found some more workarounds for a similar scrolling-related HID++ issue: https://bugzilla.kernel.org/show_bug.cgi?id=216885#c52 (I know I used dash instead of underscore in the module names, it shouldn’t matter since they’re automatically converted)

                  Alright, I found a solution based on the last comment on that bug report!

                  Scrolling applications in plasma task switcher with G903 Lightspeed (wireless mode) is so fast that is unusable, but sudo modprobe -r hid_logitech_hidpp fix this, are these bugs all related?

                  Using that command turned every tiny scroll input into a full scroll. Pairing that with Solaar, disabling smooth scrolling, now everything works correctly!
