Dear Maintainer,

Hi, since yesterday, along with xserver-common and xwayland upgrade, xbindkeys stops working with

- W: awesome: xerror:881: X error: request=GrabKey (major 33, minor 0), error=BadAccess (10)
- xbacklight -dec 10 gives "No outputs have backlight property"
And maybe others, but haven't seen yet
As neither awesome, xbindkeys or xbacklight have changed, I assume it must be X related (even if a libc6 upgrade has happened in the same time).
I'll try to downgrade to see if it's working better
Thanks

Raphael

Indeed, downgrading from 2:1.18.4-1 to 2:1.18.3-1 for
xserver-common/xorg-xserver-core/xwayland/xserver-xephyr resolved the
problem

Dear Maintainer,

After upgrading my box (from etch of last may to today's etch) the video
support is very bad under Gnome :

- Contrast (screen backlight) control keys are not working any more

- Gnome Control Center Displays tab is unable to have access to card
  or screens information and thus no screens re-organization
  (mirroring for instance) is possible that way

When upgrading apt-list-changes show me that message from xserver-xorg-core :

I tried :

1) to use the xorg.conf template

2) to downgrade xserver-xorg-core, xserver-common to 2:1.18.3-1 (using
   deb files found on http://snapshot.debian.org)

3) to update xserver-xorg-core to 2:1.18.4-2 (the one in unstable)

4) to update the kernel to 4.7.0 (the one in unstable)

Nothing worked.

The fact strange is that the X server is working (or at least seems to work).

For instance I am able to change the backlight using sysfs with something like

    echo 50 > /sys/class/backlight/intel_backlight/brightness

I am also able to use an external monitor/beamer but not to change their
relative position/mirroring with Gnome tools (I did not try with xrandr
though).
