Comment 18 for bug 494166

Same issue here on my Sony Vaio with a GeForce Go 6200/6400. Harry's workaround solves the problem temporarily. A small downside is that you have to repeat his installation procedure every time a new kernel is installed.

On the other hand, the new nvidia beta driver 195 is way better than the older one. All annoying flickering problems within Firefox while watching flash streams over zattoo or wilmaa (online-tv limited to Switzerland) are gone now!! I hope this driver version will be included in Ubuntu Lucid Lynx.
