http://ubuntuforums.org – Hy, here is a pict of my problem I've installed the 185 drivers using system->administration->hardware drivers menu i get that's noise or sometimes just freeze of whole desktop till i restart the computer after 5-10minutes of using the laptop. I really think thats software issue, cause before i have vista installed and everything work ok. I have asus m70vn laptop. I've tried the 173 drivers and everything seems to be ok, except that desktop applications works really slow sometimes. i have no fancy things enabled, just clean install of ubuntu 9.10 beta and nvidia drivers.
