Package: xfce4-xkb-plugin
Version: 0.4.3-1
Followup-For: Bug #490410
Hi,
I have just experienced the same bug using a combination of us and cs
layout. This is the relevant part of the my xorg.conf:
Section "InputDevice"
Identifier "Generic Keyboard"
Driver "kbd"
Option "XkbRules" "xorg"
Option "XkbModel" "microsoftprousb"
Option "XkbLayout" "us,cz"
Option "XkbVariant" ",qwerty"
Option "XkbOptions"
"grp:alt_shift_toggle,grp_led:scroll"
EndSection
I have played with the sources a bit and have loaded the xkb plugin into
gdb and have found out the following:
- upon startup in xkb.c::initialize_xkb(), the plugin tries to fill two
arrays(group_names and symbol_names) based on data provided by the xkb
extension. The contents of these arrays differs depending on whether the
instance of the xkb plugin comes from a the actual startup of the entire
xfce4 environment or if I RESTART xfce4panel.
- after launching xfce4 via startx. The arrays contain information for
the US keyboard only:
(gdb) p group_names
$16 = {0x1819eb0 "USA", 0x0, 0x0, 0x0}
(gdb) p symbol_names
$18 = {0x181a410 "US", 0x0, 0x0, 0x0}
(gdb) c
Continuing.
- after restarting the xfce4-panel (thus reloading the xkb plugin), I
can see the arrays already contain the expected values:
Breakpoint 11, handle_xevent (ctrl=0x1541ef0) at xkb.c:411
(gdb) p group_names
$19 = {0x1581f80 "USA", 0x1581de0 "Czechia - qwerty", 0x0, 0x0}
(gdb) p symbol_names
$20 = {0x1582570 "US", 0x1582590 "CZ", 0x0, 0x0}
Could this be some kind of race between the X server loading both
layouts and the xfce4 startup, or something like that? The plugin's
initialization function that loads the above arrays is very messy and
seems to contain quite a few hacks and workaround. I can investigate
further but I am not an xkb guru.
Actually, I currently need some workaround for this - something like
restart xfce4-panel as xfce4 runs on my parent's machine and they are
really getting confused on seeing (null) instead of the flag..
Best regards and thanks for any info,
Jan
