Hello, I have got the same issue for quite a long time now, and figured out a workaround that works for me (this is using GNOME on a Powerbook).
Running xmodmap I get: $ xmodmap xmodmap: up to 4 keys per modifier, (keycodes in parentheses): shift Shift_L (0x32), Shift_R (0x3e) lock Caps_Lock (0x42) control Control_L (0x25), Control_R (0x69) mod1 Alt_L (0x40), Meta_L (0xcd) mod2 Num_Lock (0x4d) mod3 mod4 ISO_Level3_Shift (0x85), Super_R (0x86), Super_L (0xce), Hyper_L (0xcf) mod5 ISO_Level3_Shift (0x5c), Mode_switch (0xcb) Look at mod4 and mod5, both being bound to ISO_Level3_Shift for example. Now, if I run clear mod4 by running xmodmap, ie. $ xmodmap - clear mod4 Ctrl+d Then everything works again as expected. Maybe this information helps to get to the root of the issue, Benjamin
