modifier_map Mod5 { Control_R }; }; };

The intention is to have two layouts that are switched using Caps Lack; for each layout there are 3 modifier keys: Shift, right Alt, and right Control. Thus each key is supposed to generate up to 8 different letters in each layout. For example, the following line

 key <AD02> {[w, W, a, A, b, B, c, C], [Cyrillic_tse, Cyrillic_TSE]};

aims to make the following assignments in the first layout:

w → w Shift+w → W Alt_R+w → a Alt_R+Shift+w → A Control_R+w → b Control_R+Shift+w → B Control_R+Alt_R+w → c Control_R+Alt_R+Shift+w → C

When I load this layout using xkbcomp - :0, only 4 out of 8 combinations work as expected, as follows:

w → w Shift+w → W Alt_R+w → a Alt_R+Shift+w → a Control_R+w → b Control_R+Shift+w → b Control_R+Alt_R+w → b Control_R+Alt_R+Shift+w → b

In other words, combinations of two or three modifier keys don't work. What should be changed in order to obtain the desired behavior?

  • I don't see where the type MULTI is being assigned to those keys; does adding type[group1]=MULTI work? Commented Jun 9, 2015 at 17:51
  • @BRPocock: In a sense, it did “work”: after I added this line to the file, xkbcomp started to give segmentation fault when trying to compile it. (It compiles the previous version just fine.) I guess I could now file a bug report… Commented Jun 10, 2015 at 7:52

Let's try simplifying this a little.

I'm not aware of any symbols command keys.type=MULTI, so I removed that line first.

I saved your file as keys (minus that line) and ran xkbcomp -w 10 keys. It reports:

Warning: No automatic type for 6 symbols Using for the <TLDE> key (keycode 49) Warning: Type "" is not defined Using TWO_LEVEL for the <TLDE> key (keycode 49)

(and a lot more errors after that)

So, let's add a definition MULTI3 that mimics MULTI but with 3 (6) levels:

 type "MULTI3" { modifiers = Shift+Mod3+Mod5; map[Shift] = Level2; map[Mod3] = Level3; map[Shift+Mod3] = Level4; map[Mod5] = Level5; map[Shift+Mod5] = Level6; level_name[Level1] = "Base"; level_name[Level2] = "Shift"; level_name[Level3] = "Alt"; level_name[Level4] = "Shift Alt"; level_name[Level5] = "Control"; level_name[Level6] = "Control Shift"; };

… and then assign it to TLDE:

 key <TLDE> {type="MULTI3", symbols=[grave, asciitilde, dead_grave, dead_tilde, dead_doublegrave, dead_belowtilde]};

OK, re-running xkbcomp -w 10 keys confirms that this eliminates that error.

The same type of error affects 27 other keys … so, annotating them with the desired type, and/or creating new types to handle them, should eliminate those errors.

The case of having two groups defined (which, by the way, will interact in very unpleasant ways with most tools for picking a keyboard layout, eg in Gnome) in the same file, you will have to specify the symbols and types for each group. I've never tried this myself, but eg:

 key <AD01> {type[group1]="NewTypeFor5Levels", symbols[group1]=[q, Q, Greek_theta, Greek_THETA, U03D1], type[group2]="TWO_LEVEL", symbols[group2]=[Cyrillic_shorti, Cyrillic_SHORTI]}; // vartheta key <AD02> {type[group1]="MULTI", symbols[group1]=[w, W, a, A, b, B, c, C], type[group2]="TWO_LEVEL", symbols[group2]=[Cyrillic_tse, Cyrillic_TSE]};

Once the file can be compiled, you should have better success.
