[gentoo-user] move to xfce and forget kde and gnome

[Space Cake]

hi,

after playing a lot with desktop environment first I've decided to move
from kde to gnome because kde is too "shine" and eat too much and
contains a lot of feature which I don't really need.. gnome is good but
still too fat.... so finally I've found Xfce which is perfect for my
needs... :)

my question is what is the easiest way to get rid of kde/gnome stuff? is
this enough to change my useflags to -kde and -gnome? Is there any list
what I can safely unmerge in this case?

Thank you
Laszlo

You change your profile.  You can see your current profile with:

   eselect profile list

For KDE you would use "default/linux/amd64/10.0/desktop/kde" and for 
Gnome "default/linux/amd64/10.0/desktop/gnome".

For anything else, use "default/linux/amd64/10.0/desktop".  Then do a:

   emerge -auDN --with-bdeps=y world
   emerge -a --depclean

If KDE/Gnome stuff still remains after that, use:

   emerge -pv --depclean <package>

to see what's pulling-in <package>.

Are you sure that's all? No need to change my global useflags at all? 
When I change profile and check what would be re-emerged, only a few 
minor changes exists. What I would like to achieve to get rid of all 
the fat kde/gnome stuff but of course without re install my whole 
system. Is there anyone here who already did something similar?

Re: [gentoo-user] Re: move to xfce and forget kde and gnome

[jdm]

Lazlo my use flags for keeping kde and gnome away are  -kde -gnome  -qt4

I also have 
eselect profile set 1

You may have to use /etc/portage/package.use to get guis to some packages
That may need kde or gnome

Well, I just said above to use emerge -pv to see what's pulling packages 
in.  That means you have to use your brain and see if USE flags are 
pulling-in Gnome/KDE deps.

-qt4 has nothing to do with KDE.  If any package has a qt4 USE flag that 
results in KDE dependencies, then it should be reported as a bug.  I'm 
not aware of any such packages though.

I think we agree. Nowadays I use xfce because KDE is hungry and makes
my system slower. But there is a few application (amarok - big
bloatware but I like the amarok services, umbrello, krusader, kile,
etc) which is needed and I always have a full KDE install beside xfce.
What is your strategy? You will not use any KDE related application or
if something is needed you will install it separately?

I'll try to avoid as many kde/gnome application as I can :) I don't 
really like them because I want to have my window in front of me right 
when  click on the icon :). I just started to clean-up my useflags, 
changed to desktop profile and I'll leave my machine here for the 
weekend to re-emerge everything is needed for this change. I'm sure 
some revdep-rebuild and depclean still waiting for me and also I think 
lot of kde / gnome libs will remain because of the dependencies...

Those are recent additions to the profiles. At any rate, I only started using 
the KDE one this year.

If Laszlo has default/linux/amd64/10.0 as his profile already (that's what I 
used to do), he's going to have to do an awful lot of work with USE flags. A 
full re-installation may be easier in the end.

Any time I do a fresh installation, I back the whole thing up to external 
disk at significant stages of the operation so that I can start again (if I 
need to) from much further on.

He may find that it doesn't make much of a change, depending on which profile 
he has set now.

Totally agree. I am a XFCE user, but I just love K3B, and it needs kdelibs.
I don't like KDE or Gnome, but I can live with compiling some of their
libs...

  Here's my "autodepclean" script.  It parses the output of a pretend
depclean and generates, but does not execute, a script called
"cleanscript", which has to be run as root.  Note the warning to check
"cleanscript" before running it.  Remove the commands to unmerge the
stuff you want to keep.  In addition to some gentoo-sources kernels, it
now wants to remove nano, ever since "virtual/editor" showed up in
Gentoo.  I get the warning...

!!! 'app-editors/nano' (virtual/editor) is part of your system profile.
!!! Unmerging it may be damaging to your system.

  Here's the script...

#!/bin/bash
# autodepclean script v 0.01 released under GPL v3 by Walter Dnes 2010/08/18
# Generates a file "cleanscript" to remove unused ebuilds, including
# buildtime-only dependancies.
#
# Warning; this script is still beta.  I recommend that you check the output

Interesting - thanks! It found an unused library file (qdbm) here that 
nothing else had.

One suggestion: I'd create cleanscript in /tmp rather than wherever I 
happened to be at the time.

Cool! I can see myself using this script routinely.

That said, since one *must* check the resulting script anyway, why not
start the editor directly after chmod? E.g.:

$EDITOR cleanscript

Oh, also don't forget to delete cleanscript.000 ;)

  Question... how many people have /tmp on a partition that's mounted
"noexec"?  That could be a problem.

  The autodepclean script cleans out the the temporary file with...

echo "#" > cleanscript.000

...Note the ">" which zaps cleanscript.000.  I leave it around as a

debugging aid.  This is GPL.  Feel free to append the the line...

Add a variable at the top to define the bin directory to use. Then 
users can change it to whatever suits them.

/tmp is a good default, except when it's mounted noexec.
Same for ~

Almost every reasonable choice will have times when it's not good, so 
rather shift the responsibility over to the end user :-)

Or, as Pandu said, clean up afterwards.

Not knocking your work, Walter - I like the script and I'm grateful.

So, what if I have changed the flags to -kde and -gnome, and I also ran
depclean, also used the script provided by some kind member of the list
and I still have all the kde gnome stuff on my system? Do I need some
list of packages should I unmerge? Should I simple unmerge packages
kde-base/* and so on and run revdep-rebuild after this? Is this a
working approach?

Look for KDE/GNOME packages in your world file

grep kde /var/lib/portage/world
grep gnome /var/lib/portage/world

Remove anything you don't use
emerge --depclean -a
rinse and repeat

I just cleaned off KDE (and PulseAudio, as it happens) from my system
Saturday night/sunday morning. I wasn't using the KDE profile.

Here are the steps I followed:

1) Remove all 'kde' and 'qt' USE flags from make.conf. (I didn't have
to remove qt, but I preferred to switch over to package-specific
support for it, as needed, rather than global)
2) emerge --depclean (pretend first, then add anything I *knew* I
didn't want to lose to @world, then pretend again, until there wasn't
anything that would be removed I wasn't comfortable with)
3) If there were any KDE packages left, emerge -pPv on them, to find
what was pulling them in. "emerge --deselect" the packages that were
pulling the KDE packages in. (Sometimes, this would involve supplying
an alternative. For example, I had to emerge Awesome before it would
remove knotify.)
4) Jump back to step 2, unless I couldn't get a package to disappear
with --depclean.
5) revdep-rebuild (in my case, only a Jack library was busted)
6) emerge --deep --newuse --keep-going world && emerge --sync &&
emerge --update --deep --newuse --keep-going world # This part, I left
running overnight. It succeeded, to my surprise.

I did have a couple recursive-dependency-like situations. For example,
KDE has a policykit agent, which depends on polkit. The policykit
agent wouldn't go away; emerge -pPv said polkit was pulling it in, and
said that the agent was what was pulling polkit in. In those
situations, I found I had to --unmerge a piece of the dependency loop
in order for emerge to allow it to go away or get replaced. In the
polkit case, I removed the KDE agent.

I also had to remove a few packages I do occasionally use, because
they were pulling in Qt or KDE. In particular, I --deselect'd calibre.
I've still got qt libs on my system, though, because I use
Luminance-HDR a *lot*.

I found it surprisingly painless. Note, I went through most of these
steps with X *NOT* running; I switched to a terminal and stopped kdm
before really going past step 2.

One additional note. Except for time spent compiling, this only took
about 3-4 hours. A lot of it was learning how virtual ebuilds work
(which led me to discover I needed to emerge awesome so that depclean
would drop knotify), and much of it was scratching my head over
circular dependencies and identifying the right point in the ring to
--unmerge to break the graph cycle.

I've been working from home all day today on the system. Only glitch
I've encountered was that I forgot to reset my .asoundrc after
removing pulseaudio.
