Kdeprefix for KDE 4.2: yes or no?

Well, it appears it's being tossed out by the KDE ebuilds, because I have kdeprefix in my make.conf USE flags:

The '*' after kdeprefix indicates (according to man emerge) that it is transitioned to or from the enabled state. If kdeprefix had been removed, it would have a '%' after the USE flag (indicating newly added or removed).

I recompiled my whole KDE 4.2.4, now with -kdeprefix, and the result is complete crap:
When I start KDE as a user (even with no existing KDE configuration in the home dir), none of the "KDE services" starts up. That means, e.g., that no hotkeys are available. That doesn't just mean additional user-defined hotkeys, but everything, including Alt+Tab.
When I start KDE as root, it works.

I'm trying to upgrade after a sync today, and having all sorts of problems with kdeprefix. I cannot force kdeprefix as a use flag anymore, meaning that I essentially have to use -kdeprefix from here on out. To wit:

wow. What a mess. Here's what emerge just puked out, after I set the -kdeprefix flag in make.conf:

All you guys: please follow the kde4.x guide. And especially this warning:

CRAP.

I didn't realize until I logged out and logged back in to my desktop with a -kdeprefix built KDE-4.2.4 that all of my settings, e-mail, etc. (read: EVERYTHING) would not be used since the switch over uses ~/.kde4 instead of ~/.kde4.2. Stupidly, I tried deleting ~/.kde4 and renaming my ~/.kde4.2 to ~/.kde4 while in an active KDE session. Logged out and logged back in...poof all of my settings, e-mail, etc. were toast.

Thank God for backups.

So, to save someone else the potential heartache of having pretty much your entire KDE4 setup (including e-mail) vaporized, let me hardily recommend you backup your home .kde4[.x] directory(ies) before you rebuild with -kdeprefix. The data you save could be your own.

Okay, little bit of a soapbox moment here: this is a change that folks should have been made aware of loudly before forcing it. A sticky, something, anything. Instead of potentially "dead kittens" this forced -kdeprefix pretty much certifies it. My bad for not taking care of my .kde directories, but this can create a lot of nasty afternoons for folks if they're not aware/careful.

I think, for the time being, I'm going to leave my KDE 4.2.4 built with +kdeprefix.

It's already built and installed with the 'kdeprefix' USE flag, so I'd rather wait for the next major upgrade to either 4.2.5 or 4.3 to change.

I had to create a /etc/portage/profile/use.mask file with the following entry to achieve this:

I also see kdeprefix was removed:
...
[ebuild R ] kde-base/krunner-4.2.4 USE="opengl -debug (-kdeprefix*)" 0 kB [1=>0]
[ebuild R ] kde-base/kdebase-startkde-4.2.4 USE="(-kdeprefix*)" 0 kB [1=>0]
...

Just masked, not removed.

alonbl · n00b Joined: 30 Jun 2005 Posts: 57

Why masked?
What happened?

I was pretty pissed when kdeprefix was masked. Really, really pissed.

And all because of pykde (why not slot that too?).

The worst thing - suddenly not even the ~/.kde dirs are slotted anymore... instead of .kd4.2, .kde4.3, kdelive, everything ends in .kde4. grrr...

So what are user expected to do?
Drop the kdeprefix usage?
Unmask it until they find an issue?

Will kdeprefix be supported in future?

Thanks!

I masked the global -kdeprefix and have no problems. I don't use multiple kde4 versions, but I don't want kde3 to know about kde4 programs, and vice versa. This caused some problems in the past, and makes for cluttered menus and things.

Go ahead and do this if you know what you're doing.

Since I went -kdeprefix kdm wont start kde.
startx works, it's not an xorg.conf issue (i've wiped it and X starts).
What happens is that when I type in me username and pass to kdm, the session cannot be started and kdm goes back to the login screen. The only usable log is from /var/log/Xorg.0.log.old:

What mighty be wrong?

I already rebuilt kde twice...

have you moved your .kde4.3/.kdelive to .kde4?

Yep, forgot to mention its not a user-related issue.
I've moved my .kde folders, I've created a new user... still no go.

I have the same issue as TemplarKnight has. I havn't found any solution yet. I tryed to uninstall all the KDE 4 stuff and then reinstall them, but it didn't help.

TemplarKnight · Posted: Tue Jun 23, 2009 9:03 am Post subject:

This is *at least* irritating.

I was doing normal updates and ended up with an unusable pc.
Thanks for the kdeprefix crap...

and you load the right kdm? there are no leftovers in /usr/kde/4.something or live?

there shouldn't start anything in the background - except you think about init still starting stuff.

have you looked at kdm.log?

btw - did you have any mesa updates or stuff like that? I had crashes in the past, when kdm was ok, but starting kde crashed X with sig11 if there were mesa/opengl related screw ups. Are you sure you did not update anything X?
