Status changed to 'Confirmed' because the bug affects multiple users.

It seems to me that the post installation script aborts with status 1 if fglrx is not installed.

There is in postinst:
            # Make sure we use the discrete card
            has_aticonfig="$(which aticonfig)"
            if [ X"$has_aticonfig" != X ]; then
                aticonfig --px-dgpu || true
            fi

At least on my system if I try it in a shell
has_aticonfig="$(which aticonfig)"
gives an exit code of 1 (I do not have an aticonfig executable anywhere in my path).

Wouldn't it be reasonable to change it to

            has_aticonfig="$(which aticonfig || true)"

to cater for systems where aticonfig is not present (due to fglrx not being installed)?

[Manfred Hampl (m-hampl)]

Potential workaround:

Open a terminal and issue the command

gksudo gksudo gedit /var/lib/dpkg/info/fglrx-pxpress.postinst

This will most probably ask for the password and then open an editor with the post installation script loaded.

Scroll down to the end of the file and then about ten lines back up until you find a line that reads

           has_aticonfig="$(which aticonfig)"

modify that line into

           has_aticonfig="$(which aticonfig || true)"

save the file and close the editor

finally execute the terminal command

sudo dpkg --configure -a
