I was recently checking to see if EXA was working again since the terrible day Xorg 7.1 was pushed into sid.
Guess what?
Its fixed. BUT, you have to change a few options....
Add in the options below to your device config:
Code:
Section "Device"
Identifier "Device 0"
Driver "radeon"
Option "AGPFastWrite" "off"
Option "AGPMode" "8"
Option "ColorTiling" "on"
Option "DynamicClocks" "on"
Option "EnablePageFlip" "on"
#add in these guys
#these 3 work with intel also
Option "AccelMethod" "EXA"
Option "MigrationHeuristic" "greedy"
Option "AccelDFS" "true"
#radeon specific tweak!
Option "EnableDepthMoves" "on"
#stop adding
BoardName "ATI Technologies Inc RV350 AR [Radeon 9600]"
BusID "PCI:2:0:0"
# make sure you comment out xaa stuff, of course
# Option "XaaNoOffscreenPixmaps"
EndSection
HINT! If this works, compiz-fusion should run faster, and there should be a noticeable performance difference in manipulating various gui applications. Some such as OpenOffice are not affected, however.
// What is EXA? -from wikipedia
EXA is considered a stopgap measure to improve X.Org Server performance before the server is moved entirely to OpenGL; XAA does not accelerate many 2D operations heavily used in current applications, and in particular was considered not to do enough in accelerating XRender.
EXA was adapted from KAA, the KDrive Acceleration Architecture, from the experimental Freedesktop.org Xserver. Per the initial mailing list announcement,[3] the goals are:
1. Properly accelerate XRender;
2. Be as simple as possible.
Oh and heads up, EXA is supposed to be default with xserver 1.4.1  |

I tried the options and this is what I get:
(II) RADEON(0): Direct rendering enabled
(II) RADEON(0): Render acceleration unsupported on R300 type cards and newer.
(**) RADEON(0): Option "MigrationHeuristic" "greedy"
I don't think it is supported yet for R300 and newer cards. |

| I have r300 here. Are you using the driver radeon or ati? Run sgfxi -N radeon and see if that helps too, it grabs some more updated drivers. |

I'm using the radeon driver. I'm using the sid drivers.
I was slightly afraid of grabbing the experimental drivers. Is there no down side to grabbing them? |

| With the latest sidux drivers, it does work. Just changed to them right now. |
