FreeBSD is simple.  X has never been particularly simple, and the fact

 But I am not complaining! :-) I've been told that those changes
 are absolutely needed to design the creation of new software
 more efficiently and cheaper; this is often confused with bloat,
 but it's not, it's evolution! And there's no way around.

Of course there is: if you're happy with the state of your software, 
stop there!  Don't upgrade.  Don't replace what's working with
something newer.

That option is usually more difficult than it initially seems.  The
rest of the world tends to keep on evolving.

 I would be more happy if things would really get better, or
 even not worse, but sadly, they seem to. Software gets slower
 as well as less accessible - Gtk 2, used by many programs, is
 a good (bad) example. Am I supposed to buy new computer to replace
 perfectly running systems just to keep the overall usage speed
 of everything at the same level?

As above, you don't *have* to upgrade.  Keep the old software, and the 
old hardware will run it.

Like everybody, I grumble about changes that don't seem to improve 
things at the user level.  But I try to remember that without change, 
nothing can improve.

It's also worth remembering that open source projects like xorg give
the users the rare privilege of being able to make a difference.  Test
code, provide hardware, document bugs or fixes, do or fund development.

If that were true, it might be worth noting. Unfortunately, it rarely
works like that. I recently started using a Logitech wireless
mouse/keyboard. Of course the mouse did not work in X, although it
performed fine outside of X. After investing valuable time in
Googling for a solution, I ended up editing files for HAL and adding

Section ServerFlags
Option AllowEmptyInput OFF
EndSection

to the 'xorg.conf' file.

rant
Honestly, that is not acceptable. On every Windows and MAC system I
tested, the combo works without this garbage. It just works. No
drivers to install, unless I want the extended capabilities of the
keyboard/mouse. Why does it have to be so freak-in difficult here. How
the hell are we suppose to entice potential users to non Window's
platforms when a simple thing like adding a keyboard or mouse to a
system becomes a challenge.

It appears the thread has mutated from it's unpleasant when X changes

of the spectrum.



rant

Evidently no one has been in the position to fix the problem.  The 
opportunity is there, as I was saying above.  Certainly there have been 
reports of problems with wireless keyboard/mouse of several brands; 
maybe a slightly different protocol with the wireless versions.


Whether the problem is with hal or xorg-server or the keyboard and mouse 
drivers or USB or some interaction, I don't know.  You have the 
hardware; how about doing some research to help improve this?  Just 
knowing what causes the problem would be a long way towards a real 
solution.


On every Windows and MAC system I tested, the combo works without this 
garbage. It just works. No drivers to install, unless I want the

Because the number of people using xorg are so small in relation to 
Windows and OS X.

If you stick with HAL however (using AllowEmptyInput bypasses the
autodetection), you can just use the policy file in the Handbook and
just add the DontZap option in ServerFlags or ServerLayout section.
In fact, I've just written a patch for the Handbook that adds this
information and will be committed soon. In the meantime, you can view it

Hehe, both places will work actually.

A default xorg.conf generated with the '-configure' option, will not
have a ServerFlags section (which is entirely optional), but will
certainly have a ServerLayout one. 'DontZap'  (and other options) work
in both places.

Many thanks to those who responded regarding my two questions.

With regards to the CNTL-ALT-BACKSPACE sequence and its ability
(or lack thereof) to cause an immediate shutdown of the X server...
well... I _did_ go and read the Handbook section that Manolis Kiagias

for the X server, and sadly I must report that for me, at least

precisely as described.  I even cut and pasted the code in the Handbook
that was suggested for the /usr/local/etc/hal/fdi/policy/x11-input.fdi

for me.  This is on 7.2-RELEASE/amd64.

Keep the x11-input.fdi section from the Handbook, and also add the
following line to /etc/X11/xorg.conf, at the end of the ServerLayout
section:

Option  DontZap  false

Restart your system, it should work now. (Just tried it on mine. It
won't work without both of these changes). Please report back if it
works for you!

By the way Xorg configuration becomes more and more elusive. Initially,
DontZap was enough. Then it had no effect at all and the fdi file was
needed. Now seems both are needed. What's next?

I'll test this in a few other systems and update the Handbook section
if  it seems to be the latest norm. Thanks!

down calmly, take a stress pill, and think
things over. ...

Maybe this is all fine as long as you have up-to-date hardware

on using a 21 Eizo CRT and a three button Sun mouse (where the

I hope documentation refers to how documentation should be

Trivial questions about CNTL-ALT-DEL and CNTL-ALT-BACKSPACE

2009-11-09 Thread Ronald F. Guilmette

I've just been installing 7.2-RELEASE/amd64 on a fresh/wiped system
that I plan to use as my future main workstation.

Anyway, I've already noticed a couple of things that seem to be different
from prior release that I need to ask about, i.e.:

1)  It appears that CNTL-ALT-DEL now causes a shutdown/reboot.  (I don't
know what release this new feature started in... I only just noticed it
now.)  Anyway, I'd like to know how I can disable this particular bit of
functionality. How do I do that?

2)  Prior versions of X (Xorg?) allowed CNTL-ALT-BACKSPACE to cause an
immediate shutdown of the X server, but now, that doesn't see to work
anymore.  How can I (re-)enable this functionality?

Thanks in advance for any answers.


Regards,
rfg


P.S.  Please send replies to the list.  Otherwise, I may never see them due
to my draconian and haphazard local spam filtering.  Thanks.

 Anyway, I've already noticed a couple of things that seem to be different
 from prior release that I need to ask about, i.e.:

 1)  It appears that CNTL-ALT-DEL now causes a shutdown/reboot.  (I don't
 know what release this new feature started in... I only just noticed it
 now.)  Anyway, I'd like to know how I can disable this particular bit of
 functionality. How do I do that?

# sysctl -d hw.syscons.kbd_reboot
hw.syscons.kbd_reboot: enable keyboard reboot



 2)  Prior versions of X (Xorg?) allowed CNTL-ALT-BACKSPACE to cause an
 immediate shutdown of the X server, but now, that doesn't see to work
 anymore.  How can I (re-)enable this functionality?


Thanks to the new versions of xorg, they removed that functionality.
A config file with DontZap equal to off re-enables it.

Google for DontZap to find where to put it in the config.


 Thanks in advance for any answers.

Add:
hw.syscons.kbd_reboot=0
to /etc/sysctl.conf.

Activate immediately by executing
sysctl hw.syscons.kbd_reboot=0

Welcome to the new Xorg and HAL... Please read this:

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/x-config.html

There is  a note that describes how to re-enable CTRL+ALT+BKSP
functionality.
