Description Aaron Lu 2016-11-25 02:10:42 UTC
Description of problem:
VNC screen is blank when connect through VNC with GNOME

Version-Release number of selected component (if applicable):
gnome-shell-3.22.1-2.fc25.x86_64
tigervnc-server-1.7.0-3.fc25.x86_64
tigervnc-server-minimal-1.7.0-3.fc25.x86_64
tigervnc-1.7.0-3.fc25.x86_64

How reproducible:
Always

Steps to Reproduce:
1. start vncserver(tigervnc-server)
2. connect through VNC using tigervnc client
3.

Actual results:
Get blank screen

Expected results:
Get GNOME desktop environment

Additional info:
If I change to use GNOME on xorg when login, and then start vncserver, then I can get normal GNOME in VNC session. So this sounds like a Wayland related issue. But I still cannot unlock GNOME once locked, i.e. "Bug 1353077 - Can not unlock gnome in VNC session" still applies to Fedora 25/GNOME-3.22.

Comment 1 Aaron Lu 2016-11-25 02:12:22 UTC
I should probably also list wayland related package information:
[aaron@xps13 ~]$ rpm -qa |grep wayland
libwayland-server-1.12.0-1.fc25.x86_64
ibus-wayland-1.5.14-3.fc25.x86_64
mesa-libwayland-egl-12.0.3-3.fc25.x86_64
libwayland-cursor-1.12.0-1.fc25.x86_64
xorg-x11-server-Xwayland-1.19.0-0.8.rc2.fc25.x86_64
gnome-session-wayland-session-3.22.1-2.fc25.x86_64
libwayland-client-1.12.0-1.fc25.x86_64

Comment 2 Aaron Lu 2016-12-22 03:34:39 UTC
It seems to be the same problem as:
https://fedoraproject.org/wiki/Common_F25_bugs#vino-crash-wayland

If so, feel free to close this bug and I'll use Xorg to work around this issue.

Comment 3 Aaron Lu 2016-12-22 03:36:14 UTC
BTW, the below messages seem to be emitted when vnc client established the vnc session.

Comment 4 George Petasis 2016-12-28 16:38:13 UTC
I am also having the same problem, gnome does not start under tigervnc.
I have tried various things, as described here:
http://forums.fedoraforum.org/showthread.php?t=312691

The problem seems to be gnome-shell, which does not start. Individual applications seem to work. gnome-shell writes on terminal:

 /usr/bin/gnome-shell -r

And I also have the segfault of libgtk, as already mentioned.

This error is due to XDG_SESSION_ID not being set. On a system where logind is used for session management, this should not happen.

Comment 6 Fedora End Of Life 2017-11-16 18:38:45 UTC
This message is a reminder that Fedora 25 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 25. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '25'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 25 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Comment 7 Fedora End Of Life 2017-12-12 10:19:50 UTC
Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
