Description Martin Lasarsch 2007-08-23 13:02:10 UTC

the same message is shown in the konsole as you can see on the screenshot.

Use vnc, in the vncsession start YaST2 (no matter how), start another module, close the module, see error message window.

Previous versions only showed it in the konsole window, but never opened a window.

Looks like YaST2 is responsible for this.

# strace -f -efile yast2 2>&1 | grep xmessage
execve("/usr/bin/xmessage" [...])

Might be a feature.

Comment 3 Stefan Hundhammer 2007-08-27 09:39:31 UTC

The xmessage window indeed is considered a feature: It's supposed to show the user any messages that appear on the shell if you start YaST2 from the command line. Those messages get lost if started from another X program, including KDE / GNOME menus or control centers.

I assume that this particular message had always appeared, but no user ever saw it (or none ever bothered about it).

The question is: Is there any real problem with that, or is it just an irrelevant message? Were there any problems with input?

Mike, any clue?

The XInputExtension has nothing to do with Japanese or Chinese input.

It is used for devices like Graphic tablets.

Apparently it is not necessary on VNC:

Comment 6 Mike Fabian 2007-08-27 14:19:35 UTC

It might be a qt3 bug. ‘qtconfig’ from ‘qt3’ already shows this
warning:

mfabian@magellan:~$ /usr/lib/qt3/bin/qtconfig
Xlib: extension "XInputExtension" missing on display "magellan:2.0".
Failed to get list of devices
mfabian@magellan:~$

But ‘qt4’ doesn’t show this warning anymore:

mfabian@magellan:~$ /usr/bin/qtconfig
mfabian@magellan:~$

Comment 7 Stefan Hundhammer 2007-08-27 16:15:59 UTC

OK. Then I fear VNC users will have to live with that for this release. We are phasing out Qt-3 anyway, so the bug will fix itself with the next release that will be use Qt-4.

Comment 8 Martin Lasarsch 2007-08-28 12:50:53 UTC

why not add a variable to /etc/sysconfig/yast2 and check it?

## Type: boolean
## Default: true
#
# If this variable is set to "false", the xmessage window will not appear.
# If you use vnc, you want to set it to false.
#
Y2_SHOW_XMESSAGE=true

parse it, add an simple "if = true" in the redirect function, 2 minutes work :-)

Comment 9 Martin Lasarsch 2007-08-28 12:52:29 UTC

see #8, thanks

Comment 10 Martin Vidner 2007-09-04 06:13:26 UTC

Well no, I fixed it to show an xmessage only if yast fails.
