I was bitten by the same bug while using a specific ~/.xmodmaprc to switch the option and command keys on a macintosh keyboard.
Applying the following patch works around the problem: ! Remove Mod1 and Mod4 mappings (as shown by xmodmap on fresh config) -remove Mod1 = Alt_L -remove Mod1 = Meta_L +clear Mod1 +clear Mod4 -remove Mod4 = Super_L -remove Mod4 = Hyper_L +! clear some mess coming out from ? +keycode 204 = NoSymbol NoSymbol NoSymbol NoSymbol +keycode 205 = NoSymbol NoSymbol NoSymbol NoSymbol +keycode 206 = NoSymbol NoSymbol NoSymbol NoSymbol +keycode 207 = NoSymbol NoSymbol NoSymbol NoSymbol ! Add keycodes as shown by xev -keycode 64 = Super_L -keycode 108 = Super_R -keycode 133 = Alt_L -keycode 134 = Alt_R +keycode 64 = Super_L Super_L Super_L Super_L +keycode 108 = Super_R Super_R Super_R Super_R +keycode 133 = Alt_L Alt_L Alt_L Alt_L +keycode 134 = Alt_R Alt_R Alt_R Alt_R I have tracked down precisely which of the modifications (clearing the 205-207 keycodes, using 'clear' instead of 'remove' to clean the modifiers or settings the four values for the keycodes) addressed the problem. Hopefully the xorg-server hackers may under the issue better than me. -- xmodmap failure BadValue error, 118 (X_SetModifierMapping) https://bugs.launchpad.net/bugs/524774 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
