Problems with the VNCserver

Yotaphoner · 10-30-2018, 01:13 PM

Hello, I am running ubuntu 18.04 and just sintalled a VNCserver on Gnome.

To do it, as it was the first time I tried it, I read an online guide, but there were a couple of points uncomplet or missing.

The results is I have the VNC server isntalled and I can connect to it, but when I do it from my Android tablet it only appears a grey screen.

This is the content of my config file:

Quote:

#!/bin/sh

xrdb $HOME/.Xresources
xsetroot -solid grey
#x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#x-window-manager &
# Fix to make GNOME work
export XKL_XMODMAP_DISABLE=1
/etc/X11/Xsession

I am thinking the reason of my problems is that "-solid grey", but if its thats then I don't know what to change it for.

Thanks in advance

Being a total dummy concerning X11, I have always had problems with VNCserver on Ubuntu. Figuring out a working xstartup script is a long exercise in trial and error and perusing several web sites. OpenSUSE is similarly frustrating. With RHEL/Centos/Fedora and Gnome 2 or 3, it works out of the box.

As far as I know, the solid_grey option just sets your background to this colour. You could use pink instead to see the difference.

My recommendation: Either use another distro, or use ssh with X11 forwarding instead of VNC.

For what it's worth, here is my Fedora 28 configuration:

Code:

$ cat xstartup
#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
exec /etc/X11/xinit/xinitrc
$
$ cat config
## Supported server options to pass to vncserver upon invocation can be listed
## in this file. See the following manpages for more: vncserver(1) Xvnc(1).
## Several common ones are shown below. Uncomment and modify to your liking.
##
# securitytypes=vncauth,tlsvnc
# desktop=sandbox
geometry=1366x768
# localhost
# alwaysshared
$

And how I could connect to the SSH with X11 forwarding server?? With the same VNC client? Remember that the client side is an android 4

I read about the "solid colour" and yes, it seems its only aboit the background. But I am sure it has to exists a way to fix the "little mistake" that has to be on the configuration of the VNC servee. The scenario where a VNC server is hard to implement on Ubuntu is too much stange to bealive it

Sorry I had forgotten that you do this on an Android device. There is an X server for Android, but I would agree that VNC is the usual and perhaps better way to connect to a UNIX GUI.

Maybe I shoukd try to install the xfce desktop and try with it, as no one seems to know the answer

You could also try the https://askubuntu.com site.

This is the only problem that I have, now that I fixed the problem with the fonts:

Quote:

xrdb: No such file or directory
xrdb: can't open file '/home/ubuntu/.Xresources'

That appears on the log of the vncserver, and I have no idea on how to fix it.

Any suggestion?
