I’ve installed tigervnc-server on a new fedora 40 installation and followed the setup instructions here:
When I attempt to start the vncsever I get the following error:
vncserver@:1.service: Failed to change SELinux context to system_u:system_r:vnc_session_t:s0: Operation not permitted
Is there something new required on fedora 40 for the selinux policy of tigervnc-server? I haven’t encountered this issue on prior fedora versions.
This is how it works for me:
I'm trying to run a remote desktop without monitor but i cannot find out how it works - #4 by vgaetera
Are the Docs out of date for this particular topic? 
Please ping me if you have more info on this. 
There’s no need to edit the service file and modify ExecStart.
All the necessary options can be customized using the configs:
tigervnc/unix/vncserver/vncserver-config-defaults at master · TigerVNC/tigervnc · GitHub
Ok, I’ll look that over. Just needed to know it we need to update the Docs in particular. I am making notes on some Docs that “could/should” be refreshed.
Hi, thanks for you responses. There isn’t much customization to be done to the tigervnc-server conifgs out of the box. Assuming one is running gnome desktop only an entry needs to be added to /etc/tigervnc/vncserver.users, /lib/systemd/system/vncserver@.service needs to be copied to /lib/systemd/system/vncserver@.service and a vncpassword needs to be created.
The tigervnc server is starting however it’s not able to run because the server isn’t able to change the selinux context:
vncserver@:1.service: Failed to change SELinux context to system_u:system_r:vnc_session_t:s0: Operation not permitted
Something seems to have changed in Fedora 40. I was able to run tigervnc using Fedora 39. After doing a clean upgrade to Fedora 40 I started getting this error when starting tigervnc server.
The approach you are using looks unconventional and outdated as it goes against the upstream documentation and prone to cause more mistakes.
Hi Vlad,
I don’t understand why you would think my approach is unconventional and outdated. My approach comes directly from the fedora tigervnc-server wiki. Have you read the fedora wiki? Is the wiki outdated? If so which parts of it are outdated?
Sorry i can’t test this myself, so i need to go off of your experience right now. @vgaetera can provide a more concrete answer, if the Docs are outdated I would also like to note this.
Thanks 
I think the fedora tigervnc wiki docs are most likely correct. They need to be updated with info on. how to set up the selinux policy for the tigervnc server.
