8.42.3, debian sid and compiz fusion: massive performance problems

[BigMadWolf]

I have exactly the same problem with xorg 7.3 and the latest fglrx drivers. So I will soon downgrade to 7.2... Hope it will work!

My graphic card is an ATI Mobility Radeon X700.

check the output of 'glxinfo' please and see if 'GLX_EXT_texture_from_pixmap' is listed under 'GLX extensions'. If it is not there you have no hardware acceleration by the gpu and everything is processed by the cpu hence the high cpu load and slow effects. I experience the same problems... -> http://www.phoronix.com/forums/showthread.php?t=6143

Doesn't that card work with ati or radeon driver? In some cases it works, but enables external monitor by default, so override option would be needed.

Somehow my posting disappeared... ok, again. I have the same problem. The reason for the poor performance is that indirect rendering is used. Direct rendering with AIGLX seems not to be supported by the current version 8.42.3 ('GLX_EXT_texture_from_pixmap' is missing in the 'GLX extensions' section of the output of 'glxinfo'.

I wasn't able to make the DRI work with the free ati/radeon driver under xorg 7.3 (but it works with fglrx). I think the driver is buggy, unless you have a tip for me? What do you mean with "the overriding option for the external monitor"? I've never heard about it.

This is my xorg.conf, which used to work under xorg 7.2 (please let me know if it's deprecated):

are you sure your driver's name is ati?
AFAIK, the name of the free driver is "radeon" and the binary-driver is named fglrx...

[Kano]

ati is the generic name, it switches then to radeon if possible for your card, some cards require the direct use of radeon, most work with ati.

Yeah, according to man it works.

ati is an Xorg wrapper driver for ATI video cards. It autodetects whether your hardware has a Radeon, Rage 128, or Mach64 or earlier class of chipset, and loads the radeon(4), r128(4), or atimisc driver as appropriate.

okay, didn't know that, sry
