Subject: serious (for me) Xorg 7.5 mouse/kbd problem in 8.1-STABLE
For years I have run Open-Motif on FreeBSD without issue.
I use a USB keyboard and a USB three button mouse attached to a Dell
Optiplex 960. This combination has worked fine for the past year.
This week I upgraded from 8.0-STABLE circa January 2010 to 8.1-STABLE.
I do this by doing a buildworld/installworld sequence after csup-ing
stable-supfile and rebooting. In this case I also pkg_deleted all of
my ports and am rebuilding them from source. Building Xorg is one of
the very first ports I attempt since I prefer to work in xterms not
virtual terminals.
This upgrade moved me from Xorg 7.3 to Xorg 7.5, but Open-Motif stayed
the same - open-motif-2.2.3_6 - it hasn't changed in years.
After building Xorg, as root, I ran the "Xorg -configure" command to
generate my xorg.conf.new file. Since a working /etc/X11/xorg.conf
file was still around after the upgrade from 8.0-STABLE/Xorg 7.3, I
felt no need to change anything in that file (later file comparisons
confirmed that nothing had changed).
My only relevant additions to /etc/X11/xorg.conf are these:
Section "ServerFlags"
Option "AutoAddDevices" "off"
Option "DontZap" "false"
EndSection
In my /etc/rc.conf file I have dbus and hald enabled, and that has
not changed since the beginning of 2010 after the confusion abated.
As a normal user, I start Xorg using /usr/local/bin/xinit as always.
I have several xterms configured in my ~/.xinitrc file. All those
came up in the correct location and state. I was able to open those
that started in iconic mode. In an open/raised xterm I could enter
carriage returns and see my shell prompt move down the window. But
when I tried to close/minimize an open/raised xterm, things failed.
I use the following keyboard/mouse combination (configured in my
.mwmrc file) to close (minimize) an xterm (and other applications):
Shift <Btn3Click> window f.minimize
This is also unchanged for some years. This particular setting has
no bearing on the problem I came across yesterday. I merely state
it for the record. However, this configuration triggers the "bug".
The problem is as soon as I use that Shift/Btn3Click combination,
my arrow cursor disappears, then I cannot move to or select other
xterms - I am frozen, or locked, into the xterm I was trying to
close/minimize. All I can do at this point is to kill(1) the
/usr/local/bin/xinit command to return to the virtual terminal
where I launched my Xorg session.
I am now reluctantly using the good old /usr/local/bin/twm which
is always built when Xorg is built from source. I am at a loss
as to what to look for next. I suspect Xorg, or the keyboard and
mouse driver, not the video driver, that came with. It might be
a problem with hald(8), but again, I don't know how to debug this.
Any help with this very odd bug would be greatly appreciated.
----- End forwarded message -----
This problem is known (and fixed) in newer versions of xorg-server.
See this URL for details of the problem.
<http://cgit.freedesktop.org/xorg/xserver/commit/?id=1884db430a5680e37e94726dff46686e2218d525>;
I have also attached the changes I made to the dit/events.c file.
After rebuilding xorg-server with those patches, the Open Motif
(mwm) window manager now works with the above minimize keyboard
and mouse squence. Thanks for all the help.
Regards,
web...
