SBo's SLiM login manager vs. Xfce (Slackware 14.0)
 
Hi,

On one of my machines, I have Slackware 14.0RC2 with Xfce. Until now, I've always more or less used GDM as login manager, but I want to try something new (following a general "the-less-GNOME-the-better" idea).

I added the according stanza in /etc/rc.d/rc.4 to start SLiM, switched manually to init4 and got the SLiM connection window OK.

But when I try to login with my user, I only get a brief "Failed to execute login command", and then there's the SLiM window again.

So what's the thing to do after a stock SLiM installation?

I did find something that works, sort of.

Edit my users' ~/.xinitrc like this:

Code:

exec startxfce4
After this, login works OK. Don't know if this is quite orthodox. I reckon all I have to do from here is put this .xinitrc file in /etc/skel for all future users to be able to login.

Correct me if I'm wrong... or if this seems too unorthodox.

Hello,

Have you tried running xwmconfig again? I had to do that when I used slim and it solved the problem.

No, won't do. But I sense it's time to finally do some RTFM about the innards of SLiM.

I haven't tried Slim on SW 14, but I think shutdown and restart wont work with XFCE. Something about new PolicyKit. But please do let us know how that went.

SLiM simply execute .xinitrc, so you have to configure it somehow. You can put it in /etc/skel or tell every future user to run xwmconfig. I prefer xwmconfig, because it sets everything automatically.

'exec startxfce' seems to work (as you stated), but my auto-generated .xinitrc (by xwmconfig) looks like this:

Code:

# Slackware -current (14RC2)
# prepare environment - Xresources, Xmodmap, ...
# [...]

########################################################################
##  Start xfce Desktop Environment                                    ##
########################################################################

if [ -z "$DESKTOP_SESSION" -a -x /usr/bin/ck-launch-session ]; then
  exec ck-launch-session dbus-launch --exit-with-session /usr/bin/startxfce4
else
  exec dbus-launch --exit-with-session /usr/bin/startxfce4
fi

I guess XFCE internally use D-Bus and ConsoleKit to reboot and shutdown (http://pifostap.org.ua/blog/2011/12/...down-dbus.html). In -current (few changelogs before 14.0 RC's) every window manager got updated .xinitrc so it now starts D-Bus (for DE-independent auto-mounting deamons).

OK, I did quite a lot of experimenting, and I got it right finally. I started from SBo's SlackBuild script and made a few - essentially cosmetic - alterations to it.

The trick here was to run 'xwmconfig' as simple user, of course. Which generated a nice ~/.xinitrc. Now everything works fine, logout and reboot buttons work with Xfce, and I have built a nice custom login splash for my "Microlinux Enterprise Desktop".

I tried Slim recently, but it seemed to take more time and effort to get through to the desktop.

Like most pretty things, there's usually a cost involved..

I'd compare it to the NVidia driver. When you don't know how to install it, you can spend a whole afternoon pulling your hair out. But when you know it, it's done in less than two minutes, and it's dead easy.

1) Install SBo's slim, as it comes. Use 'sbopkg' maybe.

2) Edit /etc/rc.d/rc.4 and add the stanza you can find in README.Slackware in SBo's build.

3) As a normal user, run 'xwmconfig' and choose your desktop environment (Xfce, WindowMaker, ...). This will create a ~/.xinitrc file that JustWorks(tm).

4) Eventually, set initdefault to 4 in /etc/inittab if you haven't already done that.

5) Enjoy.

SLiM is easily themable. There's an excellent HOWTO on the site.

And since we just initiated the Slackware Documentation Project, I just published a more detailed explanation there.

Enjoy.

Thanks to kikinovak, your thread and link in the post #11 is helpful to me.
I can add the a small patch, which changes location of the manpages from default /usr/share/man to /usr/man. Most of the Slackware packages have this. Thanks and sorry for my english.
The patch:
Code:

zcat mandir.fix.patch.gz
*** ./CMakeLists.txt.orig    2012-09-29 07:43:20.287147436 +0400

  set(PKGDATADIR "${CMAKE_INSTALL_PREFIX}/share/slim")
  set(SYSCONFDIR "/etc")
! set(MANDIR "${CMAKE_INSTALL_PREFIX}/share/man")
 
  set(SLIM_DEFINITIONS)
  if(${CMAKE_SYSTEM_NAME} MATCHES "FreeBSD" OR
--- 24,30 ----

! set(MANDIR "${CMAKE_INSTALL_PREFIX}/share/man" CACHE PATH "Installation Directory")
 
  set(SLIM_DEFINITIONS)
  if(${CMAKE_SYSTEM_NAME} MATCHES "FreeBSD" OR

Though maybe I'm just not very good at programming, and you can do without this patch?
UPD: This is for SLiM version 1.3.4, and you want to change SlackBuild follow:
Code:

cmake \
  -DCFLAGS="$SLKCFLAGS" \
  -DCMAKE_CXX_FLAGS="$SLKCFLAGS" \
  -DUSE_PAM=${USE_PAM} \
  -DCMAKE_INSTALL_PREFIX=/usr \
  -DCMAKE_BUILD_TYPE=$ARCH-slackware-linux \
  -DMANDIR:PATH=/usr/man
