It's reproducible every time for me right now, simply moving windows to the
second screen makes them disappear from the window list.
I've got detailed notes on how I configured Ubuntu if they are needed.
The basic setup is that I'm running on an ATI Radeon x1950, I installed
the Ubuntu ATI drivers, then the latest ATI drivers, and configured it
for dual screen using the following aticonfig commands:
aticonfig --dtop=horizontal
aticonfig --initial --desktop-setup=horizontal --overlay-on=1 --ovt=Xv
If you have any problems reproducing this let me know, I plan to re-
install Ubuntu anyway soon to check that my notes are accurate, so it's
no problem to test that it's 100% reproducible.
Wnckprop results from a console window on the second monitor are:
Name: Bottom Expanded Edge Panel
Icon Name: Bottom Expanded Edge Panel
Icons: set
On Workspace: 0 ('Desk 1')
On Screen: 0 (Window Manager: compiz)
Window Type: dock or panel
Geometry (x, y, width, height): 0, 1000, 1280, 24
Class Group: Gnome-panel
XID: 16777219
PID: 5958
Session ID: <unset>
State: sticky, skip pager, skip tasklist
Possible Actions: make above, unmake above, make below, unmake below
I've attached a screenshot of my entire desktop, showing the windows on
each monitor, and clearly showing the difference between the window list
and the window selector.

> Windows on my second monitor don't appear in the 'Window List', although if I
> add the 'Window Selector' I can find them, and Alt-Tab works ok too. This is

> I'm running Ubuntu 8.04, with ATI graphics drivers powering two monitors, and

> It also looks like dragging windows from the second monitor to the first

> more information if I ever get to that stage.
