Package: console-setup Version: 1.88 Severity: important Hello.
I have two languages in my system, to swich layouts Alt+Shift combination used. If I press and release Alt+Shift+Ctrl sometimes (depends on order of releasing) I get broken keyboard. To reproduce press this order: Ctrl, Alt, Shift and release this order: Ctrl, Alt, Shift. If Shift released first - keyboard is ok, if no - keyboard is broken. I found, problem is broken keymaps (compiled by ckbcomp). man keymaps(5) says: Note that you should be very careful when binding the modifier keys, otherwise you can end up with an unusable keyboard mapping. If you for example define a key to have Control in its first column and leave the rest of the columns to be VoidSymbols, you're in trouble. This is because pressing the key puts Control modifier in effect and the following actions are looked up from the fifth column (see the table above). So, when you release the key, the action from the fifth column is taken. It has VoidSymbol in it, so nothing happens. This means that the Control modifier is still in effect, although you have released the key. Re-pressing and releasing the key has no effect. To avoid this, you should always define all the columns to have the same modifier symbol. This problem is exactly the same. After deleting unimportant lines for Alt and Shift modificator in keymaps it work fine: alt keycode 42 = ShiftL_Lock alt shiftl keycode 42 = ShiftR_Lock alt shiftr keycode 42 = ShiftR_Lock alt shiftl shiftr keycode 42 = ShiftL_Lock shift keycode 56 = ShiftL_Lock shift shiftl keycode 56 = ShiftR_Lock shift shiftr keycode 56 = ShiftR_Lock shift shiftl shiftr keycode 56 = ShiftL_Lock So, it looks like initial problem is broken ckbcomp.
