Package: libx11-6
Version: 2:1.4.4-4
Severity: important
When changing the xkb settings with:
xkbcomp -w0 -I$HOME/.xkb -R$HOME/.xkb keymap/custom $DISPLAY
not all these settings are taken into account by some running
X applications (or worse, see below). New X applications (i.e.
those started after running the above command) are not affected.
At least the following ones are affected, from a test I've just done:
fvwm, xterm, rxvt-unicode, mlterm, and xev. Since all of them directly
depend on libx11-6, I suppose the bug is there (another reason given
below). More precisely:
* With fvwm, Ctrl-Meta-arrows have no effect.
* With the terminals, Alt-arrows have the same effect as without Alt,
contrary to my settings. A running gnome-terminal is not affected,
i.e. after running the xkbcomp command (it is needed), everything
is fine with it.
* With xev, Ctrl-Meta-arrows seem to return the same information as
before pluging out and in the USB keyboard. But I can see that it
is affected with the Alt-arrows.
The above xkbcomp command is needed because of bug 633849 (XKB settings
lost after suspend (hibernate) / resume or USB keyboard plugged in),
which affects all X applications (old and new), which is not surprising
since they are consistant with what xev says.
I've also done the following test:
1. ssh -Y to a remote machine (PowerPC). This remote machine also has
libx11-6 2:1.4.4-4, and xterm 276-2.
2. I run xterm on this remote machine from this ssh session (thus with
local display). I can see that Alt-Up has the expected effect.
3. On the local machine (where the X server is running), I plug out
the USB keyboard, then plug it in again.
4. On the remote xterm, Alt-Up doesn't have the expected effect,
but that's just because of bug 633849.
5. On the local machine (X server), I run the xkbcomp command.
6. On the remote xterm, I type Alt-Up. Result: xterm segfaults.
The backtrace shows, after installing libx11-6-dbg and redoing the
test:
Core was generated by `/usr/bin/xterm -xrm *printFileOnXError:
