I am trying to use Mutter with my Intel GMA 4500MHD (on my Thinkpad T400) in Debian Wheezy. However, it says:

Not using GLX TFP

and some effects get very slow.

How can I fix that?

possibly one way is to upgrade to mutter 3.0

To do this, you first have to add debian experimental repositories. Open /etc/apt/sources.list as su and add

# Experimental (just when explicitly demanded)
deb http://ftp.at.debian.org/debian/ experimental main contrib non-free
deb-src http://ftp.at.debian.org/debian/ experimental main contrib non-free

The next step is very important. Open /etc/apt/apt.conf as su and make sure it contains this line

APT::Default-Release "<your release>"; # (your release could be "testing" for example)

If you miss this step, your system would probably change to debian experimental.

Now update your repository information

apt-get update

and install mutter from experimental

apt-get -t experimental install mutter

On my notebook the experimental mutter didn't cause any problems until now...

Maybe you would also like to read section 3.8 of this document before you make delicate changes on your system.

  • That version is now available in Debian Unstable. Can you update? – Tshepang Jun 20 '11 at 9:14

    Can you explain this confusing statement, On my notebook the experimental mutter didn't cause any problems until now.... – Tshepang Jun 20 '11 at 9:16
  • oh, just wanted to say that I haven't encountered any problems (now I have problems again, but at this time everything was alright! – Marcel Jul 18 '11 at 14:36
