Intel D820 here with Intel Mobile GM965/GL960 Integrated Graphics
Controller. I use a docking station with two identical HP LA1951g
monitors attached, one VGA, one DVI with a native resolution of 1280 x
1024 @ 60 Hz.

First, Natty failed to detect the native resolution of VGA monitor. It
can only see 1024 x 768 (all effects were off). Maverick had no problems
with seeing 1280 x 1024 (though have used a xorg.conf file).

Even when docked and with the lid shut, the laptop still displays on the
LVDS only (?!?) - and with a weird resolution too. Attempts to shut off
the LVDS and force image on the external display leads to black screen
on all three of them followed by a system freeze (CTRL+ALT+POWER is the
only way to reboot it).

Had no such problems whatsoever with Maverick so it must be a Natty bug.
Have tried the xorg-edgers drivers and used the same xorg.conf file from
Maverick to no avail.

Since in its current status Natty is completely unusable, I had to put
Maverick back (which I am using to write this post).

Another thing: is it just me or the fonts did look a lot smoother and
clearer in Maverick than Natty ?
