[Cooker] xorg-snapshot packages can be tested

[Paulo Cesar Pereira de Andrade]

 Hi,

 The xorg-snapshot packages should be usable for testing now.
To install you need to add contrib/testing to urpmi, then just
run something like:

# urpmi xorg-snapshot

 If it ever asks for different alternatives, choose the
-snapshot one (remaining problems should be fixed soon, but
it should work with either option).

 Everything will be installed under /opt/xorg-snapshot, and
the full install requires around 315Mb.

 After installation, it should be possible to run in parallel
with current Xorg, but for safety, you should enter run level 3.
This could be done with a command like:

# service dm stop

after switching to a text console and logging in.

 After that, as a normal user, you should be able to run:

$ xorg-snapshot <xinit-args> -- <xserver-args>

 It is just a front-end to startx, and a sample usage is:

$ xorg-snapshot /usr/bin/xterm

then, once you have a X Server with a single xterm window,
run:

$ startkde &

in that xterm window.

 3d applications should work only with a few drivers, and some
will print messages about lack of certain features. Snapshot versions
of the kernel modules should be made available soon, an hopefully
some builds of X Server and Mesa alternate branches.

 The current X Server binary was compiled with a not 100%
correct -D option, so it is not possible to use the -config
option, and it will not read xorg.conf. Consider it a good
time to see how the automagic, no xorg.conf X Server works :-)


-
 A note about the "official" X Server package, that also caused
problems to some people. I did lots of testing, but installing
one package and then "rpm -Uvh --force ...", but there is a
problem when %pre script is run, and change a directory into
a symlink, where after everything is done, rpm will remove
files from the "old package", but ends up removing some files
it just installed... If you have problems, please check
"rpm -V xinitrc", "rpm -V x11-server-common" and
"rpm -V x11-server-xorg". If anything is missing, reinstalling
the package should be enough to fix the problem. A better work
around should be available, but I am not sure how to tell
rpm to not remove a file it just installed during an upgrade.
