<div dir="ltr">Package: fglrx-legacy-driver (8.97.100.7-5)<b><br></b>Error type: unmet dependencies<br><div>Concerned Debian version: Sid/Unstable<br></div><div><br></div>Full description:<br>Package
fglrx-legacy-driver (8.97.100.7-5) cannot be installed due to unmet
dependencies. The package requires any of the following virtual
packages:<br>xorg-video-abi-6.0<br>xorg-video-abi-8<br>xorg-video-abi-10<br>xorg-video-abi-11<br>xorg-video-abi-12<br><br>xorg-video-abi-12
is provided ONLY by xorg-xserver-core (2:1.12.4-6+deb7u6) in Wheezy
repositories, but oddly not by xorg-xserver-core (2:1.16.4-1) in Sid
repositories. An older version of the faulty package in question:
fglrx-legacy-driver (8.97.100.7-3~bpo70+1) is available in
Wheezy-backports and can be safely installed on Wheezy (confirmed to
work properly).<br><br><div>Proposed solutions:<br></div>I would suggest the following (mutually exclusive) alternatives:<br>1.
Remove package fglrx-legacy-driver (8.97.100.7-5) and ATI legacy driver
related dependencies (*fglrx-legacy*) from Sid repositories so that
users are not misled into breaking their setups.<br><br>2. Provide
the Sid package xorg-xserver-core (2:1.16.4-1) with the virtual package
xorg-video-abi-12 or point fglrx-legacy-driver (8.97.100.7-5) that
xorg-xserver-core (2:1.16.4-1) contains the mentioned virtual package.<br><br>3.
Rename package xorg-xserver-core (2:1.12.4-6+deb7u6) to
xorg-xserver-core-legacy (2:1.12.4-6+deb7u6), introduce that package to
Sid repositories and set up a dependency chain including
fglrx-legacy-driver (8.97.100.7-5).<br><br>As it is right now
fglrx-legacy-driver cannot be installed successfully under Sid/Unstable
and xorg-xserver-core versions above 1.12 are incompatible with this
package.<br><br>I am aware that this problem has been reported in
the past, but it was abandoned due to lack of upstream response (ATI)
and no fix/workaround was provided.<br><br>Regards,<br>Andrzej</div>
