** Summary changed:
- [Hardy] Xinerama no longer used but the replacement is not obvious!
+ Useful dual-head configuration requires manual editing of xorg.conf to set
Virtual
** Description changed:
Binary package hint: xorg
Users upgrading from Dapper Drake to Hardy Heron who have used Xinerama
to support dual monitors now have to use a different method (xrandr I
think). This isn't mentioned in the release notes and the graphical
tool for configuring dual monitors is under "Screen Resolution" in the
System -> Preferences Menu. The point being that it is quite hard to
find.
Users with multiple desktops appear to have add the following to the
xorg.conf file "Screen" section:
SubSection "Display"
Depth 24
Virtual 4000 2048
EndSubSection
Then the screen resolution tool works fine for me.
A note in the release notes like the following might help:
"Ubuntu 8.04 changes the way dual monitors are supported. Users should
edit the xorg.conf file and then use the System -> Preferences -> Screen
Resolution tool to configure dual monitors on their system. "
+
+ [More Info]
+ You should set your Virtual size to the maximum height and width of your
combined displays. So if you have two 1600x1200 displays you want to place one
beside the other, use Virtual 3200x1200.
+
+ Note that setting Virtual to greater than 2048 in either height or width
+ will prevent DRI from loading, which means that Compiz cannot be used.
+ The absolute maximum is 8192x8192.
