VNC on 11.1

English Applications

Hi,

Anyone manage to get VNC to work on 11.1? I can see the Opensuse screen that comes up after login but it just hangs there. I edited my vnc xstart file and added ‘startkde &’. I am using:

vncserver -geometry 800x600 -depth 16 :1

and

vncviewer myhost:1

/jlar

VNC has a bug in openSUSE 11.0 and 11.1 for users of KDE4. Try this console command to start vncserver:

dbus-launch vncserver

There’s a bug report here with more info: https://bugzilla.novell.com/show_bug.cgi?id=457809

Hi,

Thanks for your reply… I tried that command:

dbus-start vncserver

but I am getting:

bash: dbus: command not found

any ideas?

/jlar

I have vnc working under openSUSE-11.1 KDE-3.5.10, but not under KDE4. I spent a fair amount of time on Sunday, connected from Europe to North America via vnc, maintaining my mother’s openSUSE-11.1 PC in North America (from my European openSUSE-11.1 PC). [Both PCs are running KDE-3.5.10 - quite possibly the “best” KDE around (at this time) … ]

Typo – I meant to say: dbus-launch vncserver

The computer I am connecting to runs a dual-boot of Windows Xp and Opensuse 11.1. I connected to both (from OpenSuse 11.0) using the Remote Desktop Connection tool. RDP to connect to XP and VNC to connect to each OS. For some reason when I connect to OpenSuse it is really really slow, but using RDP to connect to XP is really quick. To setup the vnc I did the following:

dbus-launch vncserver

on the remote host… then in Remote Desktop Connection tool I selected the remote host VNC.

It should be as quick as XP or even quicker I would have thought.

There are options you can use to optimise the connection in VNC. Read these:
man vncserver: TightVNC: Manual Page for vncserver(1)
man vncviewer: TightVNC: Manual Page for vncviewer(1)
and even man xorg-x11-Xvnc: TightVNC: Manual Page for Xvnc(1)

It’s hard to extract the best combinations of options from them. I’m looking at that but won’t be finished for quite a while, principally because the bugs for VNC in KDE4/Suse are obscuring the problem for me.

VNC’s speed is a shame. I went to a lot of trouble getting 11.1 working in work, and a lot of time rooting with a Perl script to access the VPN, and now to discover that VNC renders the remote login practically useless is dissappointing. I am remote logged into XP at the moment and it’s as if I was at work. It seems that the protocol windows uses is much faster than VNC. It’s a pity the same protocol isn’t available for Linux.

9

I’m confused now, too many combinations/permutations. Can you explain in more detail the slow connection?
For the server: the operating system, the Desktop Environment (kde3, kde4, gnome), the Desktop Environment being served out, how the server is invoked/started.
For the client: the operating system, the Desktop Environment, the client software and how it’s started.

Ok, here it is:

Note, that the Remote Host is the same machine in both cases running a dual boot of XP/Suse

Local Host                            Remote Host
Windows Vista  ->   connecting to  -> Windows XP via RD
Suse 11.0/KDE 4.0 -> connecting to -> Suse 11.1/KDE 4.1 via VNC

Remote Host
To connect Suse. I logged into the Remote Host via SSH, and started the VNC server using:

dbus-launch vncserver

**
Local Host**
Started Remote Desktop (graphical version) for Opensuse… selected VNC as the protocol and then put in the ip of the remoted host and the DISPLAY.

ip-address:2

Is this wrong… it was the only way that worked. To connect to XP I simply used remote desktop in Vista.

it’s called XRDP

I don’t know what is invoked from RDP on the client invoking VNC. Probably that’s just fine – but there are two VNC versions on openSUSE. Maybe the VNC viar RDP on the client is different from the VNC on the server launched by “dbus-launch vncserver” (but I have a sinking feeling that it’s not different).
Just before giving up maybe try this:
Log ssh to the remote server. Start the dbus-launch vncserver on the remote server. Log off ssh (to keep it simple). On the client execute this console command as a normal user:

vncviewer ip-address:2

That cuts out the possibility of two connections concurrently (ssh and vnc) and the far remote possibility of three (ssh, rdp, vnc).

Fingers xrossed viva Linux!
