Re: Can't recover X on CPQ AMADA M700 (woody)
Hi Heather,
I believe this is a problem caused by the ATI graphics chip in the M700 -
it seems to cache the last view before it's shut down. One possible
solution is to flush the chip by restarting X with ctrl alt bksp - before
you snooze.
I run on an Armada 1750 which uses a slightly earlier version of the
Mobility chip. I've run other distros with Xfree 3.3.6 on the M700 without
any hitch so it may be a combination of chip, Xserver and Xfree version.

Try shutting down while at a text screen instead of a graphics screen?
A few models I've seen are timing sensitive on the return. If this is
the problem you can patch a hack into the apm scripts to chvt to a known
text console and sleep during the recovery before putting you back.
If that doesn't work, use a kernel with framebuffer support active. That
worked for me on a Savage MX/IX chipset. Seems that the X server was not
quite bright enough to set things right, but the framebuffer consoles
would.
(This also solved a similar problem with switching between text and gui
consoles.)
