Bug Description

Binary package hint: desktop-effects-kde

The bug happens on Ubuntu 8.04 Hardy (development) with the package "desktop-effects-kde" installed in version "0.3":

Problem:
KWin does not start after login with KDM because compiz is still set as default displaymanager.
A quick workaround is entering "kwin &" in a shell but the reason for it are those files remaining after compiz package deinstallation:

~/.kde/share/config/compizasWM
/etc/X11/Xsession.d/25enable-compiz

I believe that this happened because I played a bit with the "desktop-effects-kde" graphical tool (which was unable to set/unset compiz desktop effects on my machine). I uninstalled compiz but the "desktop-effects-kde" package still remained on my machine.

Solution:
This package should have compiz as dependency so that it will be removed with it together. The files mentioned above are part of the package so that would solve the problem.

The file "/etc/X11/Xsession.d/25enable-compiz" is not deleted when "desktop-effects-kde" is removed (see attachment), this should be fixed too.

Corrects behaviour to test for /usr/bin/compiz Edit (114 bytes, text/plain)

Confirmed this issue.

The problem occurs when a user simply issues a remove and not a purge of the desktop-effects-kde package, which leaves behind an Xsession file:

/etc/X11/Xsession.d/25enable-compiz

The contents of this file test for a hidden configuration file in the users home directory:

$HOME/.kde/share/config/compizasWM

And if it exists, it exports the KDEWM variable to be /usr/bin/compiz. This behaviour is incomplete, as the Xsession test for compiz should test for the compiz binary before exporting it as a valid window manager.

Please correct. I have attached the patch to correctly test for the existence of compiz binary in addition to the original test.

I just had this bug and exactly concur with Roderick Greening's description of the problem as above and his suggested fix.

Boy, there's some silly bugs around this compiz stuff :(

Compiz is still pre-alpha software, unstable and simply not integrated into any desktop environment but distros keep pushing it to pretend being cooler. I really dislike Ubuntu's default behavior on enabling Compiz after install.

But there's light at the end of the tunnel, at least with KDE4 no compiz is necessary anymore, they have perfect composition+effects integration into KWin toghether with a nice configuration interface (+ it works with OpenGL or software XRender). Don't know when Metacity will have it.

Unassign package maintainer.

I am wondering why 25enable-compiz needs to be purged.

    - DesktopEffectsCommon.py - remove ref to adept_batch and replace with install-package
  * 25enable-compiz also check whether compiz is actually installed. Thanks to
    Roderick Greening for providing the patch. (LP: #218180)

Hi,

Another difficult with this :

I use alternatively KDE3+compiz or KDE4 with the same user

In kde4, compiz is launched, but i want kwin.
/etc/X11/Xsession.d/25enable-compiz don't make any difference with kde3 / kde4 session and always check $HOME/.kde/share/config/compizasWM configuration.

No help wanted, this message is just for explain this case.
Sorry for my very poor english.
