How to increase the size of the cursor in Lubuntu 19.04?

I use Lubuntu 19.04 with LXQT on a notebook with a 15-inch display and a Full HD (1920x1080 px) resolution. I set the scaling of the display to 120 by .Xresources file in the Home directory. The cursor is not terribly small, but it's size is still annoyingly smaller than what I use in Windows.

Under the LXDE desktop environment I had a way to manage the size of the mouse cursor, but now - not. I have tried my old methods plus a couple of others already with no success yet.

So I just would like to know if there exists any way to manage it's size. I think it is logical such a way to exist, since we can see that the cursor appears in a certain size anyway - this should mean that there is a setting for that somewhere.

Solution 1:

Not from the desktop as themes do not support multiple sizes yet. There is a workaround it seems:

From the comment by sroracle to the bug report:

As a workaround, setting the XCURSOR_SIZE environment variable works. It should be noted that the Xcursor.size resource in ~/.Xresources or similar is ignored however. This issue should be looked at as out-of-box behavior on HiDPI systems is to have the cursor as small as possible.

Solution 2:

Through the usual GUI, then no—probably not yet because the LXQT team has not added this feature. There is already someone reported this issue on their GitHub page https://github.com/lxqt/lxqt/issues/953.

@comodoro This is a valid feature request and is marked as so. No option for changing the cursor size exists in LXQt settings yet but there are other ways to do so; for example, see https://wiki.archlinux.org/index.php/Cursor_themes

For the meantime you can either download large mouse cursor to substitute it, or do it yourself—here is an example of someone who trying to accomplish same thing as you → https://forum.artixlinux.org/index.php/topic,847.0.html.
