Hello,
/etc/X11/xdm/Xsetup_0 in is NOT executed, what could be the reason?
I inserted on top of file
echo "hello123" > /tmp/test123
and the file is not created! Who can help?
I'm managing SL 6.10, its deprecated I know, but no way arround, its
server of a customer
Finally I want to start x11vnc in Xsetup_0, like I am used to do it
in Suse-Installations with /etc/X11/xdm/Xsetup , the it works
perfectly sind 15 years. Now my first contact to SL/ RedHat.
Background: red hat tells that Xsetup_0 is for customizing login:

Xsetup_0 is the right file to do customizations in red hat, here a
comparison of Suse and Red Hat:

I still have a Scientific Linux 6 "virtual machine" (actually a chroot
"container") so I may be in a better position to help than most.
Are you using display :0 and display manager xdm (not gdm or kdm) ?
I just detected one big bug on my side: gdm is *not* using xdm! They are
different. (you ask the same)
Thats why gdm does not care about Xsetup_0 , the file belongs to xdm!
Then I searched the aquivalent for gdm: and I found
/etc/gdm/Init/Default :
https://urldefense.proofpoint.com/v2/url?u=https-3A__tldp.org_HOWTO_XFree-2DLocal-2Dmulti-2Duser-2DHOWTO_automation-5Flogin-5Fscreen.html&d=DwIDaQ&c=gRgGjJ3BkIsb5y6s49QqsA&r=gd8BzeSQcySVxr0gDWSEbN-P-pgDXkdyCtaMqdCgPPdW1cyL5RIpaIYrCn8C5x2A&m=clpAtpn-K92MtuvOqTBVJBJmXzSvYmOSsDq0BHG3Dng&s=xaAF72C7mLRDTvkOPPY10309oSLMKbjOfdLgi0Jw9FY&e=
On my SL 6.10 there is neither a "Init" directory no "Default". I
created Init directory, then created a "Default", with bash script
inside that makes that echo "Hello">/tmp/test123.txt
But /etc/gdm/Init/Default is not executed/ used, I chmod +x , but does
not help.
Then I detected a registered bug, that "Default" is not used due to
selinux policy: https://urldefense.proofpoint.com/v2/url?u=https-3A__bugzilla.redhat.com_show-5Fbug.cgi-3Fid-3D851769&d=DwIDaQ&c=gRgGjJ3BkIsb5y6s49QqsA&r=gd8BzeSQcySVxr0gDWSEbN-P-pgDXkdyCtaMqdCgPPdW1cyL5RIpaIYrCn8C5x2A&m=clpAtpn-K92MtuvOqTBVJBJmXzSvYmOSsDq0BHG3Dng&s=gd8sDUYk0qrWtZDgYzCYqwsQn9T9H1Kcdc0fjRzadNs&e=
