X.Org X Server 188.8.131.521 + Radeon 9200 + driver radeon - low performance
recently I found, X.org is not idiot-proof. Today I have booted up and my PC was almost useless. X server took around 80% of CPU usage. Suitable solution was to remove xcompmgr - X server is in normal with CPU, but eats a lot of memory (understand - more than usual). And also performance in glxgears is much lower (8-9x).
I'm using X.org 184.108.40.2061, graphic card ATI Radeon 9200 with "radeon" driver. My WM is Openbox (current version from Arch repository).
Some info from log:
[michal@arch-linux ~]$ cat /var/log/Xorg.0.log |grep EE
(EE) Failed to load module "record" (module does not exist, 0)
(EE) RADEON(0): [dri] RADEONDRIGetVersion failed because of a version mismatch.
[michal@arch-linux ~]$ cat /var/log/Xorg.0.log |grep WW
(WW) AllowEmptyInput is on, devices using drivers 'kbd', 'mouse' or 'vmmouse' will be disabled.
(WW) Disabling Mouse0
(WW) Disabling Keyboard0
(WW) Open ACPI failed (/var/run/acpid.socket) (No such file or directory)
(WW) Warning, couldn't open module record
(WW) VGA arbiter: cannot open kernel arbiter, no multi-card support
(WW) RADEON(0): Direct rendering disabled
And my xorg.conf - section Device (I think the most useful)
Well apparently Xorg isn't even working at all. You don't appear to have the radeon driver installed. It's probably in a package called something like xf86-video-ati. Can you try (re)installing it and starting X again?
Looks to me like you have KMS enabled in the kernel? If that's the case, you need to build libdrm with support for KMS (via the --enable-radeon-experimental-api option) and then rebuild xf86-video-ati and, possibly, Mesa.
Alternatively, you could reboot with the radeon.modeset=0 option to the kernel (disabling KMS) and see if direct rendering then works.
I think it's not a solution. Yesterday and days before was everything ok. My FPS was around 900 (after I installed xf86-video-ati - as you had advised me). Do you think the xorg.conf will told us something more? (In this case - here it is: http://kvaky.net/nahrano/xorg.conf)
And direct rendering - X.org probably tells something else, than glxinfo, see.
[michal@arch-linux ~]$ glxinfo |grep render
direct rendering: Yes
EDIT: And where can I find, what I have enabled in kernel?

Adam, you are really such a great wizard! Again, you have solved my problem. Thank you a lot.
Btw. radeon.modeset=0 changed only the size of letters in console (during boot and after pressing ctrl + alt + fx). The second option (nomodeset) was correct - my actual FPS is around 1500. I can't belive... ) Thank you.
