Post subject:  VNC won't start on new 5.5 install
I'm really not sure what's going on with fluxbox. Here is my apps file:

[startup] {xset -dpms s off}
#[startup] {xscreensaver}
[startup] {gnome-volume-manager}
[startup] {xvattr -a XV_COLORKEY -v 0}
[startup] {/usr/bin/x11vnc -nap -wait 50 -passwd mythtv -display :0 -forever -o /var/log/x11vnc.log -bg}
[startup] {KnoppMyth-run}
#Uncomment the below if you want to use a Wiimote
#[startup] {$HOME/wmd/mythtv_wiimote.sh}
[startup] {launch_irx.sh}
#Uncomment the below if you want to use VNC
[startup] {/usr/bin/x11vnc -nap -wait 50 -passwd mythtv -display :0 -forever -o /var/log/x11vnc.log -bg}
[app] (SDL_App)
[Layer] {2}
[Deco] {NONE}
[end]

I don't see any evidence that vnc is being run (log is not created). I enabled the log for Fluxbox and it just shows a bunch of variables that it can't read. How can I debug this?

Might try commenting out the 2nd occurrence of the vnc line... I dunno if launching it twice is detrimental or not.

Here is my .fluxbox/apps for reference:
Code:
[startup] {xscreensaver}
[startup] {xset -dpms s off}
[startup] {gnome-volume-manager}
[startup] {/usr/bin/x11vnc -nap -wait 50 -passwd mythtv -display :0 -forever -o /var/log/x11vnc.log -bg}
[startup] {xvattr -a XV_COLORKEY -v 0}

# start delay mythwelcome for 5 sec for xscreensaver to initialize
[startup] {/usr/bin/delay_mythwelcome.sh}

[app] (SDL_App)
  [Layer]   {2}
  [Deco]   {NONE}
[end]

Did you ever get it to work? This JUST NOW started happening to my box! It's maddening! No VNC and no log gets written. I can't see x11vnc running if I do a
Code:
# ps aux | grep x11vnc


Ideas anyone?

What does your /home/mythtv/.fluxbox/apps file contain? Did you change the password for your mythtv user?

Contents of /home/mythtv/.fluxbox/apps:

Code:
[startup] {xset -dpms s off}
[startup] {xscreensaver}
[startup] {mythfrontend}
[startup] {launch_irx.sh}
[startup] {/usr/bin/x11vnc -nap -wait 50 -passwd mythtv -display :0 -forever -o /var/log/x11vnc.log -bg}
[app] (SDL_App)
  [Layer]       {2}
  [Deco]        {NONE}
[end]


Is it possible that x11vnc or some file it depends upon is corrupt?

Remember that it just doesn't run:

Code:
$ ps aux | grep vnc
mythtv    4534  0.0  0.1   1776   548 ttyp0    S+   18:41


Can I uninstall it and reinstall it? Is it safe to:
Code:
# apt-get remove x11vnc


Or is it a dpkg task? If I apt-get install it again, will it roach my system? Do I need to point /etc/source.list to the stable repository if I try this?

Looks fine...

Possible, yes. Have you installed anything recently (via apt-get or otherwise)?

What happens if you run the same command found in your apps file from a VC as the mythtv user? As root? Do any errors spew forth to give a clue? Is there anything in /var/log/x11vnc.log?

@slow - nothing via apt-get recently. If I run the command as mythtv I get "permission denied." If I run it as root, nothing happens, I'm simply presented with a new # prompt.

Anyone know a safe way to remove x11vnc? dpkg or apt? Then should I point /etc/sources.list to the stable to unstable repository when I replace it with apt?

Thanks!

"Permission denied"? Only things I can think of off the top of my head:
* Either you can't run x11vnc as mythtv (ls -l /usr/bin/x11vnc)
or
* startx was run as root, thereby not allowing you access to display :0 (run ps -ef | grep -i x)

I don't know that re-installing will help, depends on the culprit (and seems like using a sledge hammer to install a push-pin :D )

EDIT: I take it from your earlier post that this was working at some point? /EDIT

Yeah it was working last night..

And the output of the commands I suggested? Any hints there?
Another possibility would be the x11vnc.log file is not writable by the mythtv user (ls -l /var/log/x11vnc.log).

If you do go the remove/reinstall route, be sure to use apt-get -s install before reinstalling. This will show you what will be installed/upgraded and give you a chance to back out before hosing your system...

Thanks for the tips, man. I got fed up with it and just auto upgraded. Now all is well. Wish I understood what happened to break it.
