Since updating my old desktop with an MGA450 card and two display heads,
I no longer have working Xinerama. I see the same things on both
displays. It was working fine in 7.2.
I have tried both with and without mga_hal installed and see no
Additionally, when I start up Gnome, things often seem to hang with the
window manager running, but no gnome-terminals or panels on the screen
and the background not loaded.
I don't know that these are related, but I suspect they might be.
The only error in the Xorg.0.log is:
(EE) MGA(0): [drm] DRIScreenInit failed. Disabling DRI.

(==) ServerLayout "XFree86 Configured"
(**) |-->Screen "Screen0" (0)
(**) | |-->Monitor "Monitor0"
(**) | |-->Device "Card0"
(**) |-->Screen "Screen1" (1)
(**) | |-->Monitor "Monitor1"
(**) | |-->Device "Card1"
(**) |-->Input Device "Mouse0"
(**) |-->Input Device "Keyboard0"
(**) Option "Xinerama"
(==) Automatically adding devices
(==) Automatically enabling devices
(**) Xinerama: enabled
But the remainder of the log never shows anything about MGA(1); only
MGA(0). No errors or anything else to indicate what might be failing to
Any suggestion of any way to get this running would be greatly
appreciated. If anyone has a G450 (or G550) working with 7.3, I'd also
like to hear about this.
