Hi everyone,

folowing the howto for compiz + ati I ended up with this in the terminal:...

sudo apt-get install xorg-driver-fglrx
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  xorg-driver-fglrx: Depends: libstdc++5 (>= 1:3.3.4-1) but it is not installable
E: Broken packages

can anyone help?
