So I build a new machine for the new Ubuntu release.
The hardware is an
ASUS P8H67-M LE motherboard that uses Sandy Bridge for video.
The CPU is an Intel i5
My monitor is a Visionquest that has worked very well with other video
and Ubuntu versions.
Now, I am getting video syncing problems. And when I do get everything
going, it is like I have a virtual screen extending below the actual
screen .... but without any scroll bars.
hwinfo --framebuffer gives:
> hal.1: read hal dataprocess 2069: arguments to dbus_move_error() were
incorrect, assertion "(dest) == NULL || !dbus_error_is_set ((dest))"
failed in file dbus-errors.c line 280.
This is normally a bug in some application using the D-Bus library.

So the error is a bit troubling. But this is a recent release and the
drivers having some bugs is no surprise.

So I may not even have a match of high video resolutions between the
monitor and the chip set. But with the error in hwinfo, I am not sure
that the data reported can be trusted.
I tried to find the specs on Sandy bridge video modes but there was so
much noise in Google that I got no where.
The monitor's on screen menu reports a resolution of 1680x1050 when
connected to the Sandy Bridge machine.
So anyone have any suggestions?
Perhaps a cheap video card in the interim?
Thanks
Stephen
