Kde3.5 + compizfusionwithATIRadeonM9000 @ 1400*1050 -- Linux Release Technology-Debian information. Read the following for details. Debian testing/lenny

The holiday is boring and I think of compiz. The last time in ubuntu, both beryl and cf can only be successful under 1024*768. As soon as they increase, the screen of 1/4 on the right will be spent. This is in KDE, and the goal is to make it run at a resolution of 1400*1050.

Let's talk about how to solve direct rendering In debian. After the first installation of debian for a long time can not open the hardware rendering, and then back to ubuntu, holiday before the installation of debian, I found that I installed a package of libgl1-mesa-dri. Solve the problem. Then, you can use driconf to configure some projects. After HyperZ is enabled, the performance will be improved by 30%. Run glxgears (mesautils), and the fps is stable at around 1250.

Configure xorg. conf to open some necessary projects. I added the following content to the original xorg. conf file:

51 Section "Module"
52 Load "dri"
53 Load "glx"
54 EndSection
55
56 Section "Device"
57 Identifier "ATI Technologies Inc Radeon R250 [Mobility firegl9000]"
58 Driver "ati"
59 BusID "PCI: 1: 0: 0"
60 Option "AGPMode" "4"
61 # Option "AGPFastWrite" "True"
62 # Option "EnablePageFlip" "True"
63 EndSection
64
65 Section "DRI"
66 Mode 0666
67 EndSection
Add in Section "ServerLayout"
Option "AIGLX" "true"
And change the color depth to 16 (critical ).

Install Compiz-fusion. The source of cn99 does not contain the complete package. Add the source:
Deb http://download.tuxfamily.org/sh... Too topfx/unstable /./
Then update and install compiz-fusion-kde.

Restart X and run compiz -- replace. Now everything is OK.

Conclusion: changing the color depth is a key step. The video card achieves better performance in the lower color depth, thus rendering the full screen normally.
In addition, after AGPFastWrite is enabled, it cannot enter X somehow.
