I recently installed Raring Ringtail on my Asus Eee PC 1025c, and it works well, way better than Windows 7 Starter. However, whenever I want to switch between windows or a windows or balloon pops up, it's really slow. Hibernate is also grayed out. I'm really a newbie on Linux, and this is the first time I'm using Ubuntu for real, but I've heard these could be because the graphic card driver is missing. Any ideas?
