One of the things I liked about KDE3.5 and KDE4 on Ubuntu was that the mouse cursor was this translucent arrow which looked a lot better than the default one on Windows. When I switched to Debian for some reason I didn’t have that theme installed by default. So I tried searching for it but couldn’t find the theme as its kind of hard to search for translucent cursor in kde and get sensible results.
Today I decided to search again and found this forum post about customizing Ubuntu. Over there he mentioned the names of the the cursor themes installed on Ubuntu. Using that as a base I did some more digging/searching and finally found the name of the package I had to install to get my translucent cursor back.
The package you have to install is called ‘xcursor-themes’ and the theme I needed is called ‘whiteglass’. On Debian you can install it by issuing the following command: apt-get install xcursor-themes
Hope this helps.
