Yes, it's probably possible.

OK, thank you very much for this helpfull link! I made some changes for my requested resolution on this namend xorg.conf, but there was the next problem. How to change this xorg.conf on my USB-stick?
First I tried to copy it via the filemanager. But I wasn't allowed to rename/copy any files.
OK, so i tried via terminal (sudo, rename and so on). But it seemed slitaz does not know "sudo", "rename"....
Is there a trick, how to exchange an existing file on an USB-live-version? Don't forget: I cannot see the hole screen (especially the bottom-bar).
Thamk you very much,

jo

You can install sudo from the repositories:

su to switch to the root account. The default password is root

tazpkg get-install sudo to install it

visudo to add your user account to the sudo-enabled accts; tutorials are all over the web and even a post on here

mv <origname.file> <newname.file> to move the file

cp </path/source.file> </path/destination.file> to copy a file

HIH :)

Hej Seawolf,
thank you very much! Now I'm able to exchange the xorg.conf.
But how can I save this changed file for the next start of my USB-Live-Version?
Where can I find the settings (or set it via terminal). Don't forget: I cannot see the hole screen (especially the bottom-bar).
Or another question: After I've changed the xorg.conf, how can I check, if this new xorg.conf is really working?
Please excuse my question... I'm not the best linux-user ;-)
TIA,
Jo

Hmmm, I haven't used the live USB so I cannot be sure. Perhaps the handbook will tell you... http://www.slitaz.org/en/doc/handbook/liveusb.html :-)

You can even save the config file to a different place -- say, your home directory -- and specify to use it:

Xorg -config /home/tux/my-new-xorg.conf or
X -config /home/tux/my-new-xorg.conf

If you specify a different resolution or montior refresh mode, is it become proper full-screen and not sliced?

you can move windows around and out of the screen when you press alt and hold the left mouse button. alt+right button is for resizing a window.

I made a persistent usb install on my usb to keep settings. see here:
http://forum.slitaz.org/index.php/discussion/885/how-to-keep-installed-software/#Item_7

I have slitaz3+vlc+flash as livesystem now. home folder is seperate, so I can read it from other linux distributions, too.

@seawolf: why would I want to install sudo? if I need superuser, I type "su" or "gksu" and it is the same, isn't it?

Yes. I use sudo out of habit. Also, saves some commands from executing that may need explicit root permissions, as you're running as mostly-root under sudo.
