HI,

I didnt check with Ubuntu LIVE CD. On windows XP and Feora Core 9 the mouse is

working. Also I checked with Ubuntu 9.10 and is working fine. While installing im able

to use the mouse but when installation is over and reboots im not able to use. Ubuntu

is showing the mouse pointer but its not moving :(.


If any more information needed please let me know.


System Configuration : Acer VERTION ( Intel Core 2 Duo Processor, MSI MS7259 Mother board , One 160GB Sata HDD, One 20GB IDE HDD( Ubuntu is installed On), acer ps/2 Optical mouse, acer keyboard.

See if the laser light is on in the mouse. If it is not, you may be able to mask the problem by disabling USB legacy device support in your BIOS. If it's currently disabled, try enabling.

There's apparently been a persistent bug in the driver/kernel blob provided for the i8042 PS/2 decoder chip. If that driver is being used (due to mimicry) to interface your PS/2 ports with the VIA P4M800 chipset, that could be the problem.

My guess is that your system is looking for the mouse on the USB port. Toggling the USB BIOS setting forces the hardware configuration to be re-read and then appropriate config files created.

Hi djchandler,


Thank you for the resolution. I will try disabling USB Legacy support and

let you know.
