ubuntu is starting to annoy me

[Gabor Szabo]

Let me also complain :-)
After upgrading from 8.10 to 9.04:

1) the dual screen stopped working correctly, and actually I cannot
set the screen resolution to high enough.

Does anyone know /etc/X11/xorg.conf does not seem to change when I
change the configuration via the
GUI. So how can I reconfigure the X ?

2) Ctrl-Alt-Backspace does not do anything (should restart X)

3) Switching between applications using Alt-TAB got *very* slow.
     The whole system seems to be a lot less responsive.


so far these are the biggest issues I noticed.
