Description changed to:
    I am running an up-to-date version of Dapper on an Dell Inspiron
    4150 (screen resolution 1400x1050), video card Ati Mobile Radeon
    7500 (is listed in the Gnome Device Manager).

    After an update on 2006-03-23 (there was an update to gdm today, but
    the problem occurs with both versions), the login screen looked
    weird, stripey and was unreadable (you could guess about the
    colours). Keyboard and mouse are available and seem to work
    properly, the cursor is painted correctly. After entering user id
    and password, I get logged in, however, the gnome desktop is also
    weird, stripey and unreadable. It is possible to launch applications
    by clicking on the icon location. However they are exhibiting the
    same problem.

    I am using the "Happy Gnome with Browser" login theme.

    I have tried the following:
    1. Killing X by ctrl>+<alt>+<backspace> didn't help, after relaunch, gdm brought up the stripey screen again
    2. startx after logging into a bash brought up the stripey screen.
    3. After switching to the "Human" login theme, everything worked fine. 
    4. It also possible to get an visible login screen and gnome desktop by switching to another console (using <ctrl>+<alt>+<Fx>). After returning to the gdm login console a proper login screen is shown (obviously, repaint is working properly).
