Bug Description

I frequently use <Alt>whatever to jump to controls, but I am quite frustrated by the fact that Lucid, instead of going to the control marked <Alt>T, opens up a terminal when I press <Alt>T. This doesn't happen in Karmic.

I found it in GNOME Keyboard Shortcuts, and it was set to <Alt>T. I never did that; some update must have put in that as a default. This is not a good default in my opinion; <Alt>whatever is meant to be for jumping to controls with the keyboard - in CCSM I explicitly set <Super>Z to open a terminal but I also had to set it in GNOME Keyboard Shortcuts.

Please consider removing <Alt>T as a default key for opening a gnome-terminal from the GNOME Keyboard Shortcuts defaults.

I can confirm this behaviour in a fully updated stock-standard Lucid install. After discussing this issue with pitti, it is believed to be a case of compiz reading the metacity keybindings and doing something strange with them.

http://ubuntu.pastebin.com/SnG0nep0 contains the output of:
$ gconftool -a --ignore-schema-defaults /apps/metacity/global_keybindings

&

$ grep -A1 run_command_terminal /var/lib/gconf/debian.defaults/%gconf-tree.xml

Running:
$ gconftool -u /apps/metacity/global_keybindings/run_command_terminal
removes the ALT+T binding only until the session is restarted. Upon restarting the session, the ALT+T binding returns.

Unsure if this is relevant, but I have attached hardware-info.html. It is the output of:
$ sudo lshw -html > harware-info.html

As this has enough info for a dev to work on it, I am setting this this to triaged & assigning to pitti at his request.

The gconf default for the metacity key is correct, but as demonstrated on IRC, compiz sets the key for the user during login with that wrong key combination.

I don't quite understand how compiz' key bindings work in that regard. For now I'll just revert the metacity change to avoid this problem.

I think the gconf value should have been <Control><Alt>T, not <Ctrl><Alt>T. Compiz probably just ignores <Ctrl>.

Oops, thanks for pointing out. Funny that it worked with <Ctrl> as well sometimes...

I have found that I needed to run "gconftool -u /apps/metacity/global_keybindings/run_command_terminal" then restart the session for the updated keybinding - <Control><Alt>T to stick. Before running this command, <ALT>T still opened a terminal window
This is with metacity (1:2.28.1-0ubuntu4) installed.
