HAD this issue with a custom built rig, has an onboard ATI 3300HD and a
PCIe 4890, issue started when I rebooted with a new display
configuration, I re-enabled the onboard video and tried plugging one
monitor into it and the other into the PICe card. (the onboard has HDMI
out and I was planning on hooking it up to my TV, but wanted to use my
dual monitors on my onboard too, so I was testing using both cards at
the same time. fyi no go, the two are not compatible with each other
for such a setup, I'd need a PCIe 3300 or 4300 series to do it, and the
3300 drivers are not longer included in the driver packs, so I'd need to
use a 3 year old driver pack or somehow install 2 ATI drivers side by
side... the 4890 driver is in the legacy driver pack already anyways).
First thing I did was to mv my xorg.conf file to a new name and reboot
http://ubuntuforums.org/showthread.php?t=1575262
this allowed me to get past the error and login via command line
could not startx (failed with nasty long messages)
reboot again
this time same message, but the GUI launched itself... but only one display
powered on (the 4890, but at the time I thought it was the onboard)
I had already downloaded the new ATI driver pack so I went ahead and installed
it, ran the aticonfig --initial and rebooted...
everything came back up the same as last time, I tried configuring my 2
monitors, but the ATI driver did not identify the onboard video and
would only let me select 640x480, so I disabled it and shut down.
reset my BIOS setup back to single PICe video device and rebooted...
back to square one, error message, and no GUI, but yes to command line...
went back and put my original xorg.conf file in place and rebooted (both
monitors back in the 4890 with the onboard 3300 disabled)
system restarted THE ERROR MESSAGE WAS GONE.
this is definitely a graphics based issue and is related to xorg and the
display driver/monitor hardware setup.
What I would request is that anyone with this error, please when you
post, put if you have an onboard video device and/or an addon card, what
monitor configuration you are using, how many, where they are plugged
in, if you are doing hydravision/surround display view/crossfire/SLI
and any display/hardware changes you have made recently. this should
help figure out the cause and get it resolved.
hope this helps someone out.
