amacleod: Hmm.. what was the goal? Did you want to use NO-TITLE and 
NO-BORDER together?

I have a program I would like to run on a netbook (Small screen 800x480) 
so I do not want to lose any realestate to title bar...
(I know it can come with XP but for another $50)

Also, I like the idea of the application "taking over" the netbook 
as if this device and the App are one.

It's for use by non-techies so as little interaction with linux as 
possible is desired...
Full screen no-border works for me...

I see. Hmm...

Sort of like an appliance...


The perfect setup would be to boot into a slim xwindows environment 
with no or minimal wmanger running my app but have  key combo at 
start up to boot into full linux desktop
I think this will be the year of cheap touch tablets which perfect 
for my app...THese cheap tablets are often linux based

I've just opened a little Rebol window without title bar or border, 
but it can be moved around and handles events as a normal window 
does (eg. view layout [button area] works).
I think this method, which uses a small amount of code, may be window 
manager agnostic too.

Cool! I am looking for kiosk mode for Linux with REBOL. Hopefully 
can be added to R3 View ...

or r2-forward
Sounds great Anton..
How do you move it without the title bar?

On KDE here, I can press and hold Alt key, then left-click drag a 
window with the mouse.
Ok, I've got full-screen happening here.
For R3, it looks like a very similar trick should work, even through 
wine.

This window without title bar can be moved in R2:


main: layout [origin 0 box "Drag me!" feel [engage: func [f a e] 
[if a = 'down [pos: e/offset] if find [over away] a [main/offset: 
main/offset - pos + e/offset show main]]]]

view/options main [no-title]
So you can build your own title-bar and make it behave like a normal 
title bar.

Ah, may be different under Linux. I was just trying it out under 
Windows.
Anton

Yeah, in Linux here it doesn't follow the mouse well, the window 
accelerates in the direction of movement.
Geomol

Maybe because event offsets are different? Try probe e/offset.
Anton

[2820x2]
I'm sure of it. I think in Win32 the events are relative to the window, 
while in linux they are absolute. That would explain the behaviour 
I'm seeing.
If you remove main/offset, then you get this:

	main/offset: - pos + e/offset show main

and this works properly in Linux.

Never tried View on linux - does it crash too, when you change resolution? 
:-)

In two weeks I am going to set-up new Linux server finally. I have 
got the HW - SuperMicro board. I will install Mikrotik RouterOS on 
it, and it allows me to serve as a FW/router, and iside of it I want 
to install Ubuntu server in XEN
I would like to ask - should I install including X Windows? Will 
it make REBOL life easier? (e.g. will it allow to run rebcmdview, 
so that some gfx operations will be available to cgi?)
The question also is - will it consume much more resources (memory, 
cpu) to have it installed including X-Windows?

Tested with a simple "view layout [box]" on Ubuntu Hardy with the 
wmii window manager, View does not crash when using xrandr to change 
resolution.
Seems likely other setups also wouldn't crash, but I wouldn't put 
it past Gnome to do something strange

So I just installed glorious UBUNTU Server edition. Installation 
went OK, but after 15 minutes of usege, I have big WTF? Are those 
ppl crazy? This is total piece of crap. You can't have X-Windows 
easily running there. There is NO visual administrative tool intalled 
by default. No webmin, but Ebox. At least Docs state how to install/run 
Ebox. It does NOT work, it is missing some packages. I am also left 
with my user name, and the SUDO. But - can you do everything by SUDO? 
How do I find out my real root password? I am really not an experienced 
Linux user, but I could manage that stuff with old Fedora in 2004. 
Why Ubuntu gets so much attention?

I've tried ubuntu many times with the latest trying ubuntu server 
edition. I installed webmin (not too hard). I ended up installing 
a low-end desktop environment...

But as usual I hit too many walls...

It also ran like a dog on this low end PC. It was a slow 800mhz but 
should have been fast enougg..I probably need more memory as I thing 
there was alot of disk swaping going on..


Now, I'm using ms server 2003...Atleast now I can go to my brother 
if I have a problem...He does not know linux.
I want to support Linux but I'm never happy with it in the end.

Perhaps, Syllable can one day be my server of choice ..

I will try other distributions - most probably CentOS, SuseLinux 
and maybe even Fedora once again ...

Don't know anything about the server questions, but Ubuntu by default 
doesn't have a root password - use "sudo su" to get a root terminal, 
then passwd if you want to give root a password
Pekr

[2833]
sudo su - yes, I found out that already. I wanted to get Ebox installed, 
but failed, even if I followed the documentation - I hate it .... 
this simply is NOT server which si ready to go to production. This 
is total crap ...
Izkata

do you mean setup documentation?
Ah, it says the one in Intrepid is broken
Hardy is the LTS release, though, and works

https://help.ubuntu.com/8.10/serverguide/C/ebox.html- I followed 
those instructions, but it says it can't be installed ...

https://help.ubuntu.com/community/eBox- this page says Gutsy version 
has bugs, Hardy version is stable, and Intrepid version can't be 
installed
Pekr

well, the server "works" somehow, as I can reach its web. But I am 
not hardcore linux guru to go with pure console. So I wanted to add 
webmin, but noticed there is Ebox equivalent, but was not able to 
install it. The package mechanism is strange too - too much packages. 
I liked "yum update" with Fedora - it simply installed needed patches. 
Here I tried aptitude but how do I know from so many packages, what 
I need to install. I need very simple mechanism to just apply security 
patches, nothing more, like with Windows :-)
OK, so you are saying that I need to use some older Ubuntu version? 
They officially release 8.10 version and some main packages don't 
even work? I thought that by going Ubuntu I would be more safe from 
such a hassle. I probably need to go with LTS version then?

apt-get upgrade

 or "aptitude upgrade" for just the updates.. (I've been using apt-get 
 instead of aptitude, and they don't interact well when it comes time 
 to remove packages)
LTS - Long Term Support - versions are designed to be as stable as 
possible
For example, Hardy works on my laptop no problems, but Intrepid never 
has.  Don't know about Jaunty yet.

Petr, on Ubuntu there's no root password, unless you set that manually. 
On a server, this is debatable, but on workstations/desktops (which 
is Ubuntu's focus) it makes no sense to have two passwords for what 
is basically the same user.
what do i need to install
 - that is automatic. sudo apt-get install package-name

For servers I'm just using CLI based Debian. No fancy stuff installed.

I just upgraded my Debian Etch distribution to Lenny. This works 
flawlesly. Very amazing.
I now have several entries in Grub to boot different Kernel versions. 
Can someone explain to me how this works with all the rest of the 
applications and libraries?


I can imagine that you just use a different boot image to get a different 
kernel. But how does Linux handle all the "kernel dependent" libraries?
