Bug Description

The performance of my video card is very bad with edgy. I've all updates installed.
My notebook: HP Compaq nc8230 with a 2.1 GHz Intel and 1 GB RAM.

Problems:
When I have to enter my password for administrator rights, the fade to the grey screen isn't smooth at all. Or scrolling on a website with firefox is very very slow. When I minimize or maximize a window, the rendering is also very slow.
With latest Dapper I hadn't these problems!
The CPU usage of xorg often goes up to 90 or even 100 %

I tried to use this device section in xorg.conf:
Section "Device"
        Identifier "ATI Technologies, Inc. M24 1P [Radeon Mobility X600]"
        Driver "radeon"
        BusID "PCI:1:0:0"
        Option "NoAccel" "false"
        Option "AGPMode" "8"
        Option "AGPFastWrite" "on"
EndSection
But the performance didn't get better.

If you need addtional information, please tell me.

My X600 mobility is working better than ever using:

Acer Aspire 5021Wlmi
1GB Ram
32 bits Ubuntu distribution installed in 64bits AMD processor

Direct rendering is activated and glxgears show arroud 1900 fps, flurry and openGL screen savers go faster than in any other version of free drivers.

Just with the clean default installation of Edgy.

So maybe is a computer configuration problem more than a graphic card one.

My glxgears are also arround 1900 fps (in the small window) and about 140 fps when I maximazi the window.

How can I check that direct rendering is acutally enabled?

I asked for help in the ubuntu forums:
http://ubuntuforums.org/showthread.php?t=267836

As suggested there, in addition to he options I already added, I put these also into my xorg.conf
Option "DRI" "true"
Option "ColorTiling" "on"
Option "EnablePageFlip" "true"
Option "AccelMethod" "EXA"

So my device section looks like that:

Section "Device"
 Identifier "ATI Technologies, Inc. M24 1P [Radeon Mobility X600]"
 Driver "radeon"
 BusID "PCI:1:0:0"
 Option "NoAccel" "false"
 Option "AGPMode" "8"
 Option "AGPFastWrite" "on"
 Option "DRI" "true"
 Option "ColorTiling" "on"
 Option "EnablePageFlip" "true"
 Option "AccelMethod" "EXA"
EndSection

With this config everything works well!

Thank you for taking the time to report this bug and helping to make Ubuntu better. Sorry it went unanswered for so long time.

Can you please try Gutsy Beta and see if the issue is still there? If so, please attach /var/log/Xorg.0.log and /etc/X11/xorg.conf
Please also try without any xorg.conf.

Hello,

I'm sorry, I don't have this notebook any more so I can't test it for you.

Thanks for you work!
