Sony Vaio VGN-FS215S

Hi, I have installed last week Kubuntu Dapper in my Sony-Vaio VGN-FS215S and upgraded packages two days ago. 1. Touchpad is recognized but cursors speed is really slow and can not be fixed. Tapping is not supported. Both worked fine under Breezy. 2. Changing the aliasing preferences doesn't have any effect. The same file with the same Times New Roman Font in Open Office under windows XP is clear and in Kubuntu blurred. Some characters half appear. 3. I don't know which is the appropriate choice for keyboard. There is none for Sony Vaio. I tried to use the other brand keyboards for Laptop but to no avail. 4. Winmodem is not recognized but I guess I have to buy linuxant driver. 5. Wireless card is recognized but I have to install Ndis Wrapper. 6. Adept doesn't function 9 out of 10 times but this is a general problem as I realized from the talk in the Forum. I would be gratefull for any advice Thanks Yannis
