yes there was a trouble with kms (not enabled before gdm3 starting) and
probably another issue with the choice of the driver
i did several trial/error :
with xserver-xorg-video-radeon installed (and no other radeonhd or fglrx)
i needed to:
- add 'radeon' in /etc/modules (in order to have correct maximum resolution)
- add /etc/X11/xorg.conf (copied below in order to use the radeon driver)
With these 2 additions the radeon driver is now working properly
* correct resolution
* correct openGL performance (more or less 20-30 fps instead of 1-2 fps)
* switch to vt1 and go back without hang
i can redo various configuration and send you /var/log/Xorg.0.log or
anything else if needed.
