My laptop screen is of dimension 1280x800. If I connect an external screen to the machine which is of dimension 1680x1050, I get an huge mouse pointer, but only inside windows, not on the desktop, and not on the window decoration. The video card is: VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c) The huge pointer only appears if the external monitor exceeds a specific size, but I can not tell which exactely. Reproducible: Always Steps to Reproduce: 1. Connect a large external monitor. 2. Move the mouse inside a window area. Actual Results: Huge mouse pointer. Expected Results: Mouse pointer of normal size.
sorry, cursor is not handled by KWin
iirc there's been a patch to allow cursor scaling that will likely cause this, try "kcmshell4 mouse" to set the cursor size.
