Hi all,

I am experiencing a problem that I can't resolve. Running Xorg 1.6.0 
with the intel driver (in Kubuntu 9.04), I do get a repeated blanking of 
the screen at a 1600x1200 resolution. This blanking does not occur with 
the fb driver, and it does not occur at lower resolutions. It also is 
not regular. Sometimes the screen is fine for a minute, and then it 
starts to blank out 10 times in a row at intervals of a few seconds.

I have posted my Xorg log file at

Thanks your your help
