I've installed Ubuntu 11.04 (64bit) on my new Thinkpad Edge 11 laptop from Lenovo with the following specs:

Processor type AMD Athlon II Neo Processor Speed 1.8 GHz Memory Type DDR3 SDRAM RAM 2048 MB Hard Drive Type HDD Harddisk 250 GB Grafic processor ATI Mobility Radeon HD 6310

Ubuntu has found all my hardware and it works perfectly. I have one irritating problem though: From time to time (sometimes every minute, other times every hour)the cursor freezes for about 5 sec. This happens independently from the number of processes running on the laptop. It's only the cursor that freezes - I can still tab between windows and use the keyboard.

I've installed GPointingDeviceSettings, activating the trackpoint, which btw works perfectly. Also I have installed the ATI Catalyst proprietary display driver.

Anyone has an idea of whats wrong?

Thank you in advance

Best regards, Jens
