 |
|
Did an umerge-->emerge of TigerVNC, and I can't seem to get the stupid thing to actually startxfce4 for me. Trying to start up VNC on :1, following the guide here (multiple server configuration): https://wiki.gentoo.org/wiki/TigerVNC#Multiple_Server_Configuration
For the VNC user (doward in this case)
/home/doward/.vnc/config:
| Code: | ## Default settings for VNC servers started by the vncserver service
#
# Any settings given here will override the builtin defaults, but can
# also be overriden by ~/.vnc/config and vncserver-config-mandatory.
#
# See HOWTO.md and the following manpages for more details:
# vncsession(8) Xvnc(1)
#
# Several common settings are shown below. Uncomment and modify to your
# liking.
session=xfce
# securitytypes=vncauth,tlsvnc
# geometry=2000x1200
# localhost
# alwaysshared |
/home/doward/.vnc/xstartup:
| Code: | #!/bin/sh
startxfce4 & |
/etc/tigervnc/vncserver.users:
| Code: | # TigerVNC User assignment
#
# This file assigns users to specific VNC display numbers.
# The syntax is <display>=<username>. E.g.:
#
# :2=andrew
# :3=lisa
:1=doward |
/etc/conf.d/tigervnc:
| Code: | # Config file for /etc/init.d/tigervnc
# Specify the user(s) Xvnc(1) should be run for. The syntax is: "username:display".
# example: "DISPLAYS="foo:1 bar:2" You can specify more users separated by space.
DISPLAYS="doward:1"
# Do not forget to add them to /etc/tigervnc/vncserver.users too
# Optionally override the default Xsession file
# TIGERVNC_XSESSION_FILE="/usr/share/sddm/scripts/Xsession"
# TIGERVNC_XSESSION_FILE="/etc/gdm/Xsession"
# TIGERVNC_XSESSION_FILE="/etc/lightdm/Xsession"
# TIGERVNC_XSESSION_FILE="/usr/share/slim/Xsession"
# vncsession no longer supports VNC_OPTS
# Use /etc/tigervnc/vncserver-config-defaults or $HOME/.vnc/config instead |
Then, as root, I run:
| Code: | | rc-service tigervnc start |
I can connect from remote to server-ip:5901, it asks for and accepts the vncpasswd I set up for my 'doward' user, but just loads up xsm, rather than xfce4.
I can't seem to find any logs, either. If I launch vncserver :1 as user 'doward', I do see the expected server:1.log file, but when I have tigervnc service in charge, I can't seem to locate any logs.
Any pointers are appreciated 
*edit* - More info!
Ok, so now apparently I AM getting server:1.log under /home/doward/.vnc?
On an rc-service tigervnc stop --> start, now I see this:

Still shows me xsm, log is now:

The information in the wiki was quite outdated, I updated it now. In particular, ~/.vnc/xstartup is no longer used. Everything should be configured from /etc/tigervnc or ~/.vnc/config.
And since you have session=xfce in your config, it should work.
Also from what I see in your log, it does try to start xfce:

But I don't see any subsequent xfce messages there, so maybe it crashes? Can you look with pstree what is below vncsession? |

After a recent tigervnc update broke my xfce session, I fixed it by adding this line to /etc/conf.d/tigervnc:
| Code: | | TIGERVNC_XSESSION_FILE="/etc/X11/Sessions/Xfce" |

I am having the same frustration as expressed in the initial post to this topic. I'm running xfce4, yet when I successfully connect (successfully completing the password challenge) I am shown a screen presumably run by some window manager "xsm". So I followed the suggestion above aboue the process tree and here's what I am finding:
| Code: | ryzwork /home/jlpoole # date; ps -efww |grep vnc

root 17717 17026 0 09:57 pts/6 00:00:00 grep --colour=auto vnc
ryzwork /home/jlpoole # |
I'm interested in accessing the "jlpoole" session designated as ":2", so
| Code: | ryzwork /home/jlpoole # date; pstree -p 6473
Fri Feb 16 09:59:05 AM PST 2024
vncsession(6473)───xinit(6474)─┬─Xvnc(6478)
└─xsm(6480)
ryzwork /home/jlpoole # |
So process 6480 is the culprit. The problem is, I don't seem to grasp from the Gentoo TigerVNC Wiki documentation what the cause is and how to prevent xsm from being called. Just call me "helpless." Please let me know what configuration files you'd like and I'll provide them so that there is documented here in this topic a roadmap for others to follow to fix the problem of an intervening "xsm" session when there is an existing Xfce4 running. Maybe the TigerVNC Wiki will be updated and improved as a result of this discussion and ensuing help?
Thank you,
John Poole |

Impatient am I, I decided to try experimenting and I killed the parent process above for "jlpoole:2". I found my /etc/init.d/tigervnc.2 "stopped", so I restarted it and then I saw what looked to be evidence of an Xfce4 session. Here's the console:
| Code: | ryzwork /home/jlpoole # kill -HUP 6480

I tried connecting and successfully entered a "new" Xfce4 session. Yet, my Xfce4 session of "jlpoole" on the ryzwork machine remains, unscathed, and operative. So it looks like I have two Xfce4 sessions running for jlpoole:

This is really curious, the desktop showing in my remote connection (from Windows 7) has a default Xfce2 background and appears to be a fresh session. Yet, the active Xfce session appearing in the console of ryzwork has my customizations and currently running progrsm, e.g. Firefox and Konsole. It looks like PID 18115 is associated with my earlier started Xfce4 session and PID 18116 represents a newly started Xfce session as a result of my trying to connect with VNC?? So, now I am faced with how do I configure TigerVNC and/or Xfce so I have only one desktop which is "shared" when I attempt to connect to server ryzwork with VNC?
