do you know where is the cursor  file location,  we can use a transparent  cursor file to replace the  black left arrow icon.

please read here:

https://github.com/celly/transparent-xcursor

but I  cann not find where the icon is !

read here ,I posted a issue: https://github.com/celly/transparent-xcursor/issues

Thanks

The weston didn't use cursor icon in default.

You can config cursor-theme like:cursor-theme=Adwaita in weston.ini

hi @Zhiming_Liu 

as you said ,I add cursor-theme=Adwaita in weston.ini

and create a subfolder cursors in /usr/share/icons/Adwaita/cursors, 

and copy a transparent cursor file from here https://github.com/celly/transparent-xcursor.  to  /usr/share/icons/Adwaita/cursors/ , for example: left_ptr file /usr/share/icons/Adwaita/cursors/left_ptr

Actually , the mouse cursor (black arrow) disappears in weston desktop! work! , so I change Adwaita to redglass (I copy from ubuntun desktop), actually the black arrow become RED arrow. so I make sure the solution is OK.

but our app is base on chromium(chromium-ozone-wayland )webpage. after chromium start up, the black arrow cursor comes again!

so I want to know where is the cursor icon's location displaying on  chromium?

I only create one file(left_ptr) in folder /usr/share/icons/Adwaita/cursors, where are the others? where the icons from on the chromium?

if I know the location,I can replace it with transparent files to make it disappear!

when I use  redglass Icons, it's red on weston destop,but it become black arrow again on chromium, so i thinks the icons are form different locations(files) 

Thank you very much.

Does anyone know?

It seems that chrouim is different with weston about cursor display.I have no research about chrouim.

The change about removing top screen display is tested, but thr cursor i didn't test before.

Thank you for your reply so soon.

I use   the following userspace code to move the cursor to left-lower corner to solve this problem. almsot is OK

You can add a script that can boot chrome when system start.

hi @Zhiming_Liu 

it seems I change the file clients\window.c , damage the whole weston, so can not rum wayland-chromium,

is it right?

did you test that before to modify the file clients\window.c?

thanks

[gonewithwind-peter]

yes, I used a script (chromium.service in systemd) to boot chrome. but  after comment the cursor source code, weston desktop windows disappear, nothing to display.

let me try cursor-theme=Adwaita
