[IDEA] Changing the mouse cursor speed for the Local GUI.

[STUDI]

My proposal is to add a preference for mouse cursor speed in the Local GUI. By changing the mouse DPI, we can adjust the cursor speed. The DPI setting for the mouse is controlled by an additional parameter in the cmdline.txt file called usbhid.mousepoll. The available values for this parameter are: 1, which corresponds to a DPI of 1000 (slowest mouse cursor), 2, which corresponds to a DPI of 500, 4, which corresponds to a DPI of 250, and 8, which corresponds to a DPI of 125 (fastest mouse cursor). 

Below is the content of my cmdline.txt file with the relevant parameter highlighted in bold:

console=serial0,115200 console=tty1 usbhid.mousepoll=8 root=PARTUUID=ae2af025-02 rootfstype=ext4 fsck.repair=yes rootwait


A drawback of this solution is that the changes only take effect after a system restart.

I don't recall having any issue with mouse cursor speed.

Is there a particular display where this type of setting is needed?

The speed of the mouse cursor movement depends on the mouse model itself. I use a metal case (with front and rear plastic panels) that consolidates all ports onto one rear panel and offers an M2.SATA interface. I selected from several available (and of course, not too expensive because what's the point in buying a gaming/hi-tech mouse that costs more than the RPi itself?) mouse models, and the one with the best range under these conditions unfortunately has a low DPI resolution, making mouse usage quite cumbersome. "Faster" mice, unfortunately, have too weak a radio transmitter.

From my perspective, navigating the local GUI displayed on the TV with a mouse is far more convenient than trying to use a remote control (or a wireless keyboard, using a set of keys). So, it's not about a bug or a malfunction but about providing an additional option to configure the mouse. (OK, I can handle editing the cmdline.txt file, but not every user might be able to).

Why don't you just use your Smartphone to operate moOde and let the display just show the Playback UI. It's so easy.
Keyboard/mouse/remotes are a really a huge step backward and I'm not inclined to add any special features for this form on navigation.

Because at home, a large screen is more convenient in many ways. Moreover, in the presence of guests, it's the only option to showcase presentations. Unfortunately, the smartphone screen is not very comfortable for me, and besides, the phone serves as an internet router (no need to describe why it has to be the internet link). It's simpler not to block the phone. De gustibus non est disputandum. Getting back to the point, it's just a suggestion. If the new version requires installation from an image, I'll manage. My intention was to offer an option for those for whom using the vi editor is a barrier.
