Description Dmitry Kagan 2005-02-02 05:13:59 UTC

It is impossible to switch keyboard layouts using left alt+shift or ctrl+shift
when 3 keyboard layouts defined in xorg.conf. Here is my xorg.conf relevant section:

Identifier "Keyboard1"
Driver     "kbd"
Option     "XkbRules" "xorg"
Option     "XkbModel" "pc105"
Option     "XkbLayout" "us,il,ru"
Option     "XkbOptions" "grp:alt_shift_toggle"

I can only switch between layouts using right alt+shift, but not with the left
alt+shift. Same thing happens when configuring ctrl+shift - only the combination
 on the right side of the keyboard works. 
This problem didn't exist in XFree 4.3.

In Bulgaria often we use two bulgarian keyboard layouts.
The problem is similar/same to this on Dmitry.
Sample layout setxkbmap:
setxkbmap -model pc105 \
 -layout "us,bg(phonetic),bg(bds)" \
 -option \
 -option "grp:alt_shift_toggle"

&#1045;quivalent x.org settings don't help.

Switch to next group with ALT_R+SHIFT_R work fine always.
But switch to previous group ( ALT_L+SHIFT_L ) work only when current layout is
second or third.
When layout is first, i.e. us, we cannot switch to third as expected.

Problem is reported, but in bulgarian :) , here :

I have problem with switching between more than four keyboards. 

In xorg.conf I have:
Option "XkbLayout"	"us, cz_qwerty, ru, de, il, ar"

Even if I change the order or remove some of the defines, 
only between the first four ones I can switch.

System: ArchLinux - currenct (~0.8)
Version of xorg: 6.8.2-6
Version of xfce: 4.2.3.2
Version of windowmaker 0.92.0-2 (tried too)

Comment 3 Anton Zinoviev 2006-01-05 10:21:31 UTC

This bug is caused because the LockGroup(group=N) action does not work properly
when the keyboard layout has 3 groups and N is negative.

LockGroup(group=-1) cycles the groups in this way:

group3 -> group2 -> group1 -> group1

LockGroup(group=-2) cycles the groups in this way:

group2 -> group1 -> group3 -> group1

LockGroup(group=-3) cycles the groups in this way:

group1 -> group2 -> group3 -> group1

(In reply to comment #3)
> when the keyboard layout has 3 groups and N is negative.

And is anyway possible to set groups more then 3 or set N as positive?

(I updated to Xorg 7.0.0 and problem remains)

i already fixed this in xorg-server a while ago.
