[Bug 19406] Blank Screen, X freeze on my notebook ( Ati Mobility 9600 with radeon driver), ONLY with X.Org 7.4

[Pedro R]

Here goes my Xorg log and lspci -vn output.

About the DRI mode, that's what was set by default with Debian lenny, I didn't touch it.

After a quick peek at Xorg radeon module website, i added the following to my Device section:

        Option          "EnablePageFlip"        "1"
        Option          "ColorTiling"           "1"

Now i'm getting excellent performance and perfect stability, using XAA and AGPMode set to 1. The level of performance is the same i got using fglrx v8.37 back when i had openSUSE 10.3 with Xorg 7.2.

I tried the EXA settings, but the performance improvement over XAA with the above settings is only a few percent, at the expense of 100% cpu use (vs 70% with the XAA)!
