probleme xorg 7.1

La nuit dernière aprés avoir fait un apt-get upgrade, impossible de redémarrer le serveur X.
J'ai remarqué que xorg était passé de la version 7.0 à la 7.1
Ne trouvant rien sur Google, j'ai laissé tomber en attendant d'avoir plus de renseignements, et ce fût une bonne initiative, car j'ai trouvé sur Usenet la cause et la solution du probléme.


Cette version xserver-xorg 1:1.1.1-3 a été envoyée par erreur sur unstable, alors qu'elle était destinée à la branche expérimentale.

La solution fût de rétrograder vers le xserver-org de la testing.

J'ai donc fait un apt-get install xserver-xorg/testing qui m'a installé une version antérieure puis un apt-get update suivi d'un apt-get upgrade qui m'a permis de récupérer cette fois la bonne version de xserver-org destinée à la unstable.

Puis reboot et lancement du serveur x sans problèmes.


Voici le communiqué officiel sur cette erreur ;

Summary: - Unstable users,
please place xserver-xorg-core 1:1.0.2-9 on
hold,
or retrieve it from testing
or fetch your latest video driver from
experimental.

- Users of testing and stable are not affected.


An upload of xserver-xorg 1:1.1.1-3 was incorrectly made to unstable
today. The intended target was experimental. The correct current
version for unstable is 1:1.0.2-9.

The chief binary package affected is xserver-xorg-core. Other affected
packages are xdmx, xdmx-tools, xnest, xserver-xorg-dev and xvfb.

1:1.1.1-3 corresponds to X11R7.1, while 1:1.0.2-9 belongs to X11R7.0.
The consequence of this upload is that old X11R7.0 video drivers in
unstable will fail to load and the Xserver will fail to start, with an
error message similar to:

(II) LoadModule: "i810"
(II) Loading /usr/lib/xorg/modules/drivers/i810_drv.so
(II) Module i810: vendor="X.Org Foundation"
compiled for 7.0.0, module version = 1.5.1
Module class: X.Org Video Driver
ABI class: X.Org Video Driver, version 0.8
(EE) module ABI major version (0) doesn't match the server's version (1)
(II) UnloadModule: "i810"
(II) Unloading /usr/lib/xorg/modules/drivers/i810_drv.so
(EE) Failed to load module "i810" (module requirement mismatch, 0)
...
(EE) No drivers available.

Fatal server error:
no screens found



Please choose one of the following actions as a temporary workaround:

1) place xserver-xorg-core 1:1.0.2-9 (and the other xserver-xorg
packages) on hold

or

2) if you have already been affected then grab your xserver-xorg
package[s] from testing and downgrade back to 1:1.0.2-9

or

3) come join the future and grab your new video driver from experimental

Versions of latest video drivers and other X11 packages in testing,
unstable (old X11R7.0 versions, both) and experimental (new X11R7.1
versions) are summarised at
http://qa.debian.org/developer.php?login=debian-x@lists.debian.org

We apologise for the inconvenience. Discussions are underway at
debian-devel to further evolve our processes to help reduce the
likelihood of this mistake being made again in the future.

X11R7.1 is nearly ready for unstable in its own right and should have
arrived within the fortnight.
