I have a testing account I use often. That account gets used in my real machines and
virtual machines. For many years I have used a left-handed mouse (mouse buttons reversed).
Because the virtual machine passes the mouse buttons transparently, I wrote a snippet for
that user's .bashrc file to test the mouse button configuration and swap the mouse
buttons in kcminputrc as necessary. That way I can use a left-handed mouse regardless of
which environment the account gets used.
To test my mouse buttons I run the following in that user's .bashrc:
kreadconfig --file $PROFILE_HOME/share/config/kcminputrc --group Mouse --key
MouseButtonMapping
Simple enough.
Today I booted my PII machine that has a partition for Trinity 3.5.13. I login from the
command line, which means X is not yet running. When I logged in with that testing account
I received the following message:
NVIDIA OpenGL Driver requires CPUs with SSE to run.
The current CPU does not support SSE.
Superficially, I saw this message because originally I had cloned a testing partition from
another hard drive and that partition had the proprietary Nvidia drivers installed. The
PII machine does not support those drivers. Hence the messages.
The real mystery is what is kreadconfig and kwriteconfig doing that indirectly causes
those messages? I suspect a linking problem, which ldconfig resolved after I removed the
Nvidia packages. Nonetheless, why are those two commands querying X libraries when X is
not running? Is this a feature or a bug? :)

I don't think we should go much farther in the investigation: the
dependency of kwriteconfig on kdelibs brings automatic dependency on X
libraries even if it is a console program.

Good point. That is one reason I like Qt4 much beter than Qt3. For
applications that don't need X, you don't pull that stuff in. Qt3 is a
single monolithic library with everything, while Qt4 is a collection of
21 libraries. For something like kwriteconfig, it would probably only
need libQtCore.

Thanks to both.
For you folks more experienced with coding TDE and Qt3, are there any
clever ways to eliminate the overhead with the non X commands? Seems
that would be more efficient and shave a few micro/millisecond
response times here and there, especially for older hardware. :)

On 20 Dec 2011, Timothy Pearson spake thusly:
I was not implying any porting to Qt4. :) Is there a decent technical
reason why the X overhead can't be eliminated from the non X TDE commands?
In theory it might be possible to modify the Qt3 source and add an X-less
application constructor. I have no idea how complex that would be.
Of course this would still pull in the X shared libraries, incurring
most of the startup costs nonetheless. Fixing *that* would be a lot more
work. (Also, who knows how many places inside Qt3 assume the existence
of a live X display connection? After all, they've always had one they
can rely on.)

Trolltech did the separation in Qt4. Their major libraries are
libQtCore, libQtGui, libQtMultimedia.so, and libQtNetwork.so. The other
libraries essentially add on additional functionality.
The same sort of thing could be done with Qt3, but I question the value.
If someone is building a new application, they would probably just

LOL. The libraries you refer to are already in memory. They don't have
to be loaded again. That's what a shared library does. Even if they
weren't in memory, the system would have to be instrumented to measure
the change. It would be imperceptible to the user.

It would not be a giant benefit to users who already have loaded the

Trinity applications as stand alone.

Okay, computer science majors. Quit trying to see who can crow the loudest. :)

Trinity session.
Fair enough. Too bad. :(
Here's an easy option:
if [ -r ~/.kde/share/config/kcminputrc -a \
"x`grep LeftHanded
~/.kde/share/config/kcminputrc`" != "x" ]; then
echo left
else
echo right
fi

Yes, I missed that.

fi In my original message I asked why I saw specific
Nvidia error
messages when using an allegedly non-gui command in a console outside of
X. I solved that mystery and was shown that the commands were built with
X dependencies.
Yes.
The discussion since then is why those non-gui
commands can't build
without the X dependency. My "too bad" comment was in reference to
building those commands otherwise. :)
That's one reason Qt4 has multiple libraries. Doing that for Qt3 seems
to be reinventing the wheel. BTW, I tried to build Qt4 without the X
libraries, even though there is a configure option --without-x. It
didn't work. However, I could write a program that did not link to any
X libraries. Also, programs written to Qt4 (not KDE4) work fine in
KDE3, graphical or otherwise.
