Comment 3 for bug 272358

Okay, this is my last comment :)

If your problem is that a keyboard layout switching shortcut like "Shift+Shift" doesn't survive a reboot when autologin is enabled, then you can fix it like this:

Go to System->Prefences->Sessions. You'll see a "Sessions Preferences" dialog with your startup programs. Click on "Add" to add a new startup program. Create a new startup entry like this:
Name: Apply Keyboard Settings
Command: setxkbmap

This will allow your keyboard shortcuts to take effect upon rebooting. I've confirmed that this works for me, using Ubuntu 8.04, with my keyboard switching shortcut "Shift+Shift."

After add this startup program, my keyboard shortcut now survives rebooting.

However, I'm not sure if the original poster was using autologin.
