Black display for only users

[sreerampa]

Hi,

I have a RHEL 7 srever with an NVIDIA P4000 card. I have installed vitualgl and Turbovnc. The display manager is gdm (I have just installed lightdm, but have not tested it).

The problem I am facing is that when I use turbovnc from root, it works flawlessly, but as soon as I use it from a user account all it shows is a black screen. We also have LDAP users and the problem is seen with both LDAP and local users.

Looking for some direction in this regard,

Thanks

Assuming you're using the latest version of TurboVNC, I am not sure what
could be causing that. I personally tested TurboVNC 2.2 with all of the
window managers that are commonly available under RHEL 7:

I'm happy to look into the problem if you can give me more information
that might help me reproduce it.

HI DRC,

I am seeing the same issue as this. As root everything works fine. When I open a session as a NIS user the screen is black. These users weren't generated by RHEL 7, They were done by RHEL 5. So there might be something missing in their home directory that is required. Let me know what other information you need. 

Thanks

HI

I Created a user locally on this new server and everything works. I am pretty sure at this point it has something to do with something missing from the users accounts.

Any insight would be super helpful. 

Thanks

Which window manager? If it's GNOME, then I could easily see this being
a problem with the XDG environment. Have you tried MATE?

[DRC]

There is really nothing in TurboVNC that cares whether the user is local
or NIS, so this is very likely to be a window manager issue and not a
TurboVNC issue. If you can't get MATE to work, then I have no clue. If
MATE works but GNOME doesn't, then you might also try setting
TVNC_WM=gnome-session, which will force xstartup.turbovnc to load the
window manager directly rather than through xinit.

It is something with the account and the windows manager. I can't login at the console either. I will keep playing with it. 

thanks for your help.

I'll ask again-- did you try a non-XDG window manager, such as MATE?  I have a strong feeling that this is somehow XDG-related.

I tried mate locally at the console and it does the same thing. Logins shows a black screen then goes back to the login screen .

Ouch. OK, then that's definitely something I have no idea how to solve
and which is out of scope for TurboVNC.

I figured it out. I had a .profile file in the directory. It didn't like something in that file. I removed it and everything works. For some accounts I had to remove the .local and let Rhel 7 generate it again. Thanks for the help.
