waht does this mean

amy

when i typed

Code:
compiz --replace
i getCode:
pardesi@pardesi-desktop:~$ compiz --replace
/usr/bin/compiz.real: GLX_EXT_texture_from_pixmap is missing
/usr/bin/compiz.real: Failed to manage screen: 0
/usr/bin/compiz.real: No manageable screens found on display :0.0

and nothing else

It most likely means that either your video card is not new enough to support XGL/composite or you don't have the correct video drivers installed (or enabled).  Please post the output when you run the quot;glxinfoquot; command in a terminal window.

here is it Code:
pardesi@pardesi-desktop:~$ glxinfo

Well, the extension that the error message claims is missiing is clearly listed as being available in your glxinfo output...  however, it looks like it is being provided through software rendering using the Mesa libraries.  That should work, but be extremely slow.  Make sure that you have the hardware accelerated video drivers installed for your card.  Either the ATI or Nvidia proprietary drivers.  (assuming you have either an ATI or Nvidia card)

Edit: From the output, it looks like you have an ATI card.

so how do i install Xfree86-DRI ...

Sorry.  I can't help you with ATI.  I've only ever messed with nvidia.  However, you might try using these:   from : localhost/albertomilone.com/driver.html

Edit: Those appear to only be for dapper and edgy.  Sorry.

thanks everything is fine now ....i just need to install beryl
