I'm still seeing this bug with XFree86 4.3.0.dfsg.1-6ubuntu11 (synced to SVN trunk @ r1777). Fabio M. Di Nitto told me to follow up as this should have been fixed.
I have a normal British "Windows" keyboard with the Windows/Menu keys, configured like this: Section "InputDevice" Identifier "Generic Keyboard" Driver "keyboard" Option "CoreKeyboard" Option "XkbRules" "xfree86" Option "XkbModel" "pc104" Option "XkbLayout" "gb" EndSection xmodmap says this: $ xmodmap xmodmap: up to 3 keys per modifier, (keycodes in parentheses): shift Shift_L (0x32), Shift_R (0x3e) lock Caps_Lock (0x42) control Control_L (0x25), Control_R (0x6d) mod1 Alt_L (0x40), Alt_L (0x7d), Meta_L (0x9c) mod2 Num_Lock (0x4d) mod3 mod4 Super_L (0x7f), Hyper_L (0x80) mod5 Mode_switch (0x5d), ISO_Level3_Shift (0x7c) Not totally understanding the X keyboard model, I'll try and explain what happens. My Metacity is configured to switch workspaces on super-arrows. When I let go of the super/Windows key I'd expect the workspace switching popup to go, but it persists until I press it again, as if it wasn't a modifier key. The magic xmodmap line: xmodmap -e 'clear mod4' -e 'add mod4 = Super_L' fixes this temporarily. My GNOME keyboard settings applet says that "super is mapped to the Windows key" is the default setting. Pressing and releasing the left Windows key in xev produces these: KeyPress event, serial 26, synthetic NO, window 0x3000001, root 0x8e, subw 0x0, time 1593258, (104,3), root:(108,539), state 0x0, keycode 115 (keysym 0xffeb, Super_L), same_screen YES, XLookupString gives 0 bytes: "" KeyRelease event, serial 26, synthetic NO, window 0x3000001, root 0x8e, subw 0x0, time 1593375, (104,3), root:(108,539), state 0x40, keycode 115 (keysym 0xffeb, Super_L), same_screen YES, XLookupString gives 0 bytes: "" When I go to the GNOME keybindings applet to configure a super-key combination, when I press the super key it doesn't wait for a key along with the modifier, but stops at "Super_L". If I use Meta it waits for me to hit another key and will display something like "<Alt>5". Anything else I can do to help debug this?
