Comment 11 for bug 507305

Hi, just to let you know, finally I resolve "slow mouse" problem, this solution applies in Kubuntu 10.04 LTS version 32 and 64 bits, also applies to ubuntu 10.04 and 11.04.

For my Dell computer: Dell Inspiron 15 (C15P32_225LCO), AMD Athlon II Dual-Core Mobile P340 (2.2 GHz), Mem 2GB DDR3, 250GB HD. video ATI Mobility Radeon HD4250. You just need to download from ATI web site the latest drivers. selecting the drivers for ATI Mobility Radeon HD4250 you will get a .sh file "ati-.......sh", to avoid problems you can reboot your computer and enter as ubuntu (failsafe) then enter as a root to the console, and run the .sh file. Reboot your computer and you will get the mouse working correctly and video working smoothly
