Hi, Please check the type of the reported Xsession and other files: ls -laZ /etc/X11/xinit/ Or the easiest to check this is to try LXDE live image: https://kojipkgs.fedoraproject.org//packages/Fedora-LXDE-Live/Rawhide/20201014.n.0/images/Fedora-LXDE-Live-x86_64-Rawhide-20201014.n.0.iso For sure, I tried using the above LXDE Live spin image [root@localhost-live ~]# ls -alZ /etc/X11/xinit/ total 36 drwxr-xr-x. 5 root root system_u:object_r:bin_t:s0 4096 Oct 14 05:39 . drwxr-xr-x. 6 root root system_u:object_r:etc_t:s0 4096 Oct 14 05:39 .. -rwxr-xr-x. 1 root root system_u:object_r:bin_t:s0 2321 Jul 30 17:42 Xclients drwxr-xr-x. 2 root root system_u:object_r:bin_t:s0 4096 Jul 30 17:50 Xclients.d -rwxr-xr-x. 1 root root system_u:object_r:bin_t:s0 1490 Jul 30 17:42 xinitrc -rw-r--r--. 1 root root system_u:object_r:bin_t:s0 1870 Jul 30 17:42 xinitrc-common drwxr-xr-x. 2 root root system_u:object_r:bin_t:s0 4096 Oct 14 05:39 xinitrc.d drwxr-xr-x. 2 root root system_u:object_r:bin_t:s0 4096 Oct 14 05:39 xinput.d lrwxrwxrwx. 1 root root system_u:object_r:bin_t:s0 26 Oct 14 05:39 xinputrc -> /etc/alternatives/xinputrc -rwxr-xr-x. 1 root root system_u:object_r:bin_t:s0 3552 Jul 30 17:42 Xsession Perhaps you need this [root@localhost-live ~]# ls -alZ /etc/lxdm total 48 drwxr-xr-x. 2 root root system_u:object_r:etc_t:s0 4096 Oct 15 08:27 . drwxr-xr-x. 128 root root system_u:object_r:etc_t:s0 12288 Oct 15 08:35 .. -rwxr-xr-x. 1 root root system_u:object_r:bin_t:s0 68 Aug 12 03:17 LoginReady -rw-r-----. 1 root root system_u:object_r:etc_t:s0 1193 Oct 15 08:27 lxdm.conf -rwxr-xr-x. 1 root root system_u:object_r:bin_t:s0 68 Aug 12 03:17 PostLogin -rwxr-xr-x. 1 root root system_u:object_r:bin_t:s0 68 Aug 12 03:17 PostLogout -rwxr-xr-x. 1 root root system_u:object_r:bin_t:s0 68 Aug 12 03:17 PreLogin -rwxr-xr-x. 1 root root system_u:object_r:bin_t:s0 68 Aug 12 03:17 PreReboot -rwxr-xr-x. 1 root root system_u:object_r:bin_t:s0 68 Aug 12 03:17 PreShutdown -rwxr-xr-x. 1 root root system_u:object_r:bin_t:s0 1284 Aug 12 03:17 Xsession Thank you for the commands output and for the link, that should be enough for troubleshooting. As I am not aware of any possibly related change in selinux-policy, I wonder what could have changed in lxdm or elsewhere in rawhide. What is your kernel version?
