I'm using 11.10 and I'd like to change mouse cursor size more bigger.
How can I do it?
I cannot find any settings of mouse cursor size.

It seems
It seems that, if your cursor theme supports multiple sizes then you could change the mouse cursor size /1/,/2/,/3/. Either with the .Xresources /4/ file or with your DE configuration file. The KDE is using kcminputrc /3/, the gui is on the way.
The easiest way to enlarge the mouse size is to install and enable a mouse theme with larger pointers.
Background
The X11 mouse themes are composed from the pixel images /5/. So they have a native resolution, scaling could make them pixelated.
Links
In Ubuntu 24.04 you can change the mouse cursor size in the Settings app. In Settings select Accessibility -> Seeing -> Cursor Size and select a new cursor size from the mouse Cursor Size gallery.
In the above screenshot the second mouse cursor in the gallery is selected. You can click a different mouse cursor to make the mouse cursor size either smaller or larger. Cursor size can be combined with Zoom to make it easier to see the cursor.
