Compiz-Check -- no more "Desktop effects could not be enabled"

[Forlong]

Yeah, you have the proprietary ATI driver installed, which is, of course, not suitable for your hardware.

Remove it like this:

sudo apt-get remove --purge xorg-driver-fglrx xorg-driver-fglrx-dev

Then REBOOT and try again.

Thanks - that did the trick

I got "desktop effects could not be enabled". I'm a newbie and really don't know what to do.

Gathering information about your system...

 Distribution:          Ubuntu 8.10

 Graphics chip:         ATI Technologies Inc Rage Mobility P/M AGP 2x (rev 64)
 Driver in use:         Unknown
 Rendering method:      AIGLX

Checking if it's possible to run Compiz on your system...

 Checking for texture_from_pixmap...               [ OK ]
 Checking for non power of two support...          [ OK ]

There has been (at least) one error detected with your setup:
 Error: Software Rasterizer in use

ATI Rage chips are not capable of running Compiz, sorry.

when i run compiz from terminal it only gets so far and I have to use ctrl-z to drop out of it; after which i have to restart as everything freezes except terminal.

wanderer@wanderer:~$ compiz
Checking for Xgl: not present. 
Detected PCI ID for VGA: 01:00.0 0300: 10de:0150 (rev a3) (prog-if 00 [VGA controller])
Checking for texture_from_pixmap: not present. 
Trying again with indirect rendering:

If you need more info, just ask. I am new to Linux and Ubuntu.
Many thanks,

Do you have a dual-head setup?

[berilac]

I am not certain what a dual-head setup is, which probably means I don't have one
Can you enlighten me?

[Forlong]

Sorry, I just wanted to know if you are using two monitors, which is known to break Compiz on some setups.
