Re: TigerVNC does not start after update

I'm dissapointed with how they did a break change with half-assed alternative, and just shrug with it.
I've tried following all suggestions here and still keep having problem with it, with the nearest I could to is just returning error code 0 SUCCESS on systemd start.
I don't know what caused the problem with it even with strace and we just gave up with this. I've already request a proposal to switch to X11vnc to HR because of this.

You've provided no info for someone to help you.  I updated the wiki distilling out what I thought were key points to get this working.  Post what you did and what isn't working.

Here's some logs and configs if you need it.

cat ~/.vnc/config

session=xfce
geometry=800x600
localhost

cat /etc/pam.d/tigervnc

let me know if you can trace the problem

Re: TigerVNC does not start after update

It looks like in the update, /etc/pam.d/tigervnc was modified, to remove the pam_selinux.so lines

Edit: Nevermind, I must be tired, didn't look
