Debian stretch is out, a lot of obsolete packages, a lot of major upgrades, which all in all resulted in quite a painful transition the last few days. But I’ll tell you more about that in the following posts.
I don’t really spend much time on Linux nowadays so KDE (along with KDM) has always been my goto solution for a jack all trade no-BS works-out-of-the-box desktop environment. And it worked like that just fine, until… well you know how software goes. KDE has been upgraded, KDM has been depreciated and replaced with SDDM.
I also use
xsession so that I have a common way of starting session scripts and daemons (such as this one) and configuring stuff across different desktops. I generally selected custom session in the display manager and that was it. But SDDM does not seem to provide a way to do so, or at least that’s not so clear.
By default, it will execute
/etc/sddm/xsession which itself sources
/etc/X11/Xsession to which it will pass as argument the value of the Exec line in the desktop file (located in
/usr/share/xsessions) describing the currently selected session.
If we want to bypass this, we need to scrap the argument passed to
/etc/X11/Xsession no matter what SDDM thinks the current session should be. To do so create a wrapper for Xsession in
#!/bin/sh export PATH=/bin:/usr/bin:/usr/local/bin:/sbin:/usr/sbin:/usr/local/sbin # Discard argument, we don't care about selecting the desktop environment. /etc/X11/Xsession
And now configure SDDM to use this instead of its own version of it, in
