X Server and XFCE4 Session Issues

Hi BLFS Support Team,



Before I start, some general information: I am using BLFS & LFS version 12.3.



I was following the BLFS XFCE guide for building the XFCE desktop environment for my OS, https://anw.is-a.dev/mrrpos . But recently, I came across an issue where after compiling xfce4-session and following the guide to setup ~/.xinitrc and then issuing the startx command, the X.Org Server started, got a blank screen for ~2 seconds and then crashed, saying the following:

xauth:  file /root/.serverauth.8420 does not exist





X.Org X Server 1.21.1.16

X Protocol Version 11, Revision 0

Current Operating System: Linux mrrpos 6.13.4 #9 SMP PREEMPT_DYNAMIC Thu Jul 31 19:41:51 BST 2025 x86_64

Kernel command line: BOOT_IMAGE=/boot/vmlinuz-6.13.4-lfs-12.3 root=/dev/sdb1 rootdelay=10 ro



Current version of pixman: 0.44.2

The XKEYBOARD keymap compiler (xkbcomp) reports:

Errors from xkbcomp are not fatal to the X server

Session lifetime based on X11 requested, but X11 support not compiled in.

xinit: connection to X server lost



waiting for X server to shut down (II) Server terminated successfully (0). Closing log file.


But, I already have xfce4-session built with both X11 support as well as Legacy SM. I do not understand the issue that exists. Now, a little detail on what I did:

I was building the XFCE packages from source as normal, installing the dependencies too.

Similarly, I built the  https://www.linuxfromscratch.org/blfs/view/12.3/xfce/xfce4-session.html  package as normal, installing the required packages and some other recommended ones too.

After configuration, I clearly saw: "* X11 Support: yes" and "* Legacy session management: yes".

I built the package using make and installed it.

I ran the following:

update-desktop-database && update-mime-database /usr/share/mime




Next I edited ~/.xinitrc exactly as instructed.

I ran startx.

I got the "Session lifetime based on X11 requested, but X11 support not compiled in." error after which it stopped.


Please help me solve my issue. Thank you for your time.



Thank you,

Subhrajit Sain,
