CSS cursor property not working

[hgluka]

This might be an issue with my system, but the change introduced in 418276a to fix #3054 doesn't seem to be working. Then, to confirm, I tested the different cursors on this page: https://www.w3schools.com/cssref/tryit.php?filename=trycss_cursor and found out that a lot of them don't work, including pointer.

Steps to reproduce are:

1. Visit https://www.w3schools.com/cssref/tryit.php?filename=trycss_cursor
2. Hover over different words in the right pane.
3. The cursor should be different for each word. If not, you have reproduced the issue.

If the cursor doesn't change in general, then it is not related to the changes I made :-D

[hgluka]

Yes, I meant that I noticed the larger issue while testing your change. Sorry for the confusion :D

Mostly I'm wondering if someone can reproduce it or if it has something to do with my setup.

[aartaka]

Yes, I can reproduce it. I wonder whether it's DE/WM/GTK to blame for missing some cursor icons 🤔

[aadcg]

I can't reproduce on EXWM.

[hgluka]

I don't know if it's relevant, but I don't have the issue in other browsers (with the same DE - Gnome 42.5).

I'll test it out tomorrow on my laptop with CWM.

[hgluka]

Ah, so the issue is with Guix on a foreign distro. Guix needs some environment variables to be set, and systemd (in my case) doesn't set them. Here is a similar issue with the Emacs package: https://issues.guix.gnu.org/53379 So the problem isn't Nyxt specific.

To get the proper cursor theme, I put EXPORT XCURSOR_PATH='/usr/share/icons' in my .zshrc (and also changed my sly config to preserve the value) and it works perfectly. @aartaka let me know if that fixes it for you as well.

[jmercouris]

Artyom is running Guix as an OS, so I suspect the problem is slightly different! A good start perhaps!

[aadcg]

Good investigation @hgluka!

[aartaka]

To get the proper cursor theme, I put EXPORT XCURSOR_PATH='/usr/share/icons' in my .zshrc (and also changed my sly config to preserve the value) and it works perfectly.

I cannot easily test it right now, so let's settle on explaining it with my desktop environment deficiency 😛

[hgluka]

It very well could be a DE issue. There is this part of the Arch Wiki (neither one of us is using Arch, but still) that points in that direction.

[aadcg]

I believe we can close this one for now. I wonder if we should add a small note on the manual about this env var.

[hgluka]

Sorry, I totally forgot to follow up on this. Should I close the issue now or wait and see about adding that note to the manual?

I don't know what the criteria is for that. There isn't a lot of stuff in the Troubleshooting section.

[aadcg]

I can imagine arguments both for and against adding a note about it in the manual. We'll do it as you find most reasonable @hgluka. What do you say?

[hgluka]

Well, if it really is DE/WM related, then it could be affecting lots of users (even if they don't notice). I'd say we should add a note for that reason. Plus, the fix is pretty simple and harmless. I can make a PR for it.
