Ubuntu Networking :: Remote Desktop Stopped Working ?
Mar 8, 2011
I have a remote desktop app for my ipod that i use every now and then, but after about a week and a half of not using remote desktop on either my ipod or my computer, it seems to have stopped working. the problem is with my computer rather than my ipod. when i go to menu>system>preferences>remote desktop, the area where it is supposed to give you the ip address, or whatever it is to connect remotely, is no longer a number, but just the word "localhost". i only saw this after my ipod told me it could not find the host, so i checked and thats when i saw localhost. putting that into the remote desktop app did nothing, so i tried my ip address and that didnt work either. clicking on "localhost" brings up evolution mail which wants me to send it as an email, strangely. not sure whats going on here.

Well I guess the topic says it all. I've recently upgraded to Maverick from Lucid all went smoothly until i restarted and realized that the remote desktop server included stopped functioning all of a sudden. tried other vnc servers with no luck.

I recently setup an ssh tunnel and wrote a script to connect to my Home PC from my laptop no matter where I am.
I have previously tested this on my own network and multiple other networks while I was over at my friends houses, and it worked completely fine.
So just now I decided to use it after about a day or two after not using it and now nothing happens. Normally it prompts me for a password and takes about 5 seconds then I am in.
I'm using openssh, vinagre, and dyndns for the hostname. Here is the script:

Remote desktop viewer has stopped working in ubuntu 10.04. When I click on the icon in the top panel. The message Starting Remote Desktop viewer appears in the bottom panel for about 20 seconds and then it disappears and nothing further happens.
Yesterday I disabled ipv6 which greatly speed up thunderbird email and coincidently solved a problem I was having with Google earth not connecting to the server.
I do not know if this is what is now causing the problem with Remote Desktop viewer.

For more than a year I was happily using my Fedora 11 remotely through VNC over ssh. I was using desktop 0 on port 5900 so people at the office can see what I am doing.
Yesterday I upgraded to Fedora 12, then 13 and then 14. I installed all updates of F14. All went well until I came to use this server from home as usual. The server was not responding.
I brought up /etc/X11/xorg.conf from a backup tape because I discovered that it is there that screen 0 is set and not in /etc/sysconfig/vncservers and rebooted. No success!
At the command lsof | grep LISTEN, I could not see a listener on port 5900
I activated screen 1 on port 5901 and I could log in OK and with lsof I could see listeners for ports 5901 and 6001 but I need screen 0!
During the day I tried many things including removing the vncserver packages with yum and re-installing them, removing the .vnc folder in the user home folder and starting from scratch. The server is still refusing connection!

I have a Laptop with Ubuntu 10.04 and a Netbook with Remix 10.04. I'm trying to connect by Remote Desktop from the Laptop to the Netbook. Remote Desktop wasn't installed by default in Remix so I installed it via software centre. I then configured Remote desktop in both machines. When I do Connect on the laptop all I get is a black screen and then it closes with the message "Connection to host was Closed". This happens when I try either VNC or SSH. The other thing that's odd, although both machines are on the same WLAN and I checked "configure networkautomatically to accept connections" on both machines, the Laptop doesn't find the other machine in Remote Desktop. What am I/have I done wrong or have I ommitted something?

I just remotely updated my uncle's Ubuntu 10.10 desktop to 11.04. My uncle has no computer skills, so it is very important that I troubleshoot his problems using VNC. After completing the 11.04 upgrade, I was not able to connect to him via VNC. After some fiddling around I was able to connect by turning off the confirmation option in the Security section. We are now using the password security option. The problem is that my uncle does not have any security against my peering eyes.
I tried reinstalling Vinagre, but that didn't help. Is it possible to get the confirmation option working again somehow?
Is there a download link for Vinagre 3.01 (deb)?

I'm wondering if anyone is having a similar problem as mine when running Hulu Desktop. The application starts fine, but when I try to select anything to watch, the green progress bar continually resets over and over again as it tries to buffer a video, and playback never starts as a result. This happens for low, medium, and high quality. Hulu Desktop was working perfectly fine a few months ago. I've always been running Ubuntu 9.10 (64-bit) with the latest 64-bit Flash pluggins, and didn't have a problem before. Running Hulu Desktop from the command line doesn't reveal any error messages either.

I don't know why but show Desktop Ctrl-Alt-D suddenly stopped working for Firefox only (in all workspaces).
Any ideas what might have caused this? Any work-arounds? (apart from Ctrl-Alt-(arrow) / switching to a different workspace - which is a fair workaround)

The desktop effects on my system stopped working. They were working fine up to a couple of days ago. Now it says I need to check my configuration for xorg. How do you do that?
Also this appears to have started after another user was using my system and crashed it. They said that it just shut-off with no explanation as to what happened.
lspci -v shows this
HTML Code:
01:05.0 VGA compatible controller: ATI Technologies Inc RS300M AGP [Radeon Mobility 9100IGP] (prog-if 00 [VGA controller])
Subsystem: Toshiba America Info Systems Device ff02
Flags: bus master, fast Back2Back, 66MHz, medium devsel, latency 66, IRQ 16
[Code].....
How do I get back to the systems default drivers?
I do NOT wish to have to reinstall F14 yet again because the system has been very stable since the last install.

When I configure my remote desktop preferences I am not able to connect using a VNC client to my ubuntu computer. The password box pops up when I type in the password it says it could not authenticate. I have changed the password in the remote desktop preferences and this has not solved the problem. I tried to find a way to reinstall the remote desktop application on ubuntu, but I cannot find what its name is and reinstalling vncserver did not help.

I have a notebook with an Nvidia Quadro NVS 130M. Desktop effects were working on OpenSUSE 11.2. Last week I upgraded to OpenSUSE 11.3, and now desktop effects do not work. When I try to enable them, a box pops up that says something like "desktop effects are not supported on your hardware / configuration. Do you want to try anyway?". If I "try anyway", it does NOT work - I get a jumbled screen that is mostly black, but sometimes objects appear when I mouse over them.
I have the proprietary nvidia drivers (version 256.53) loaded and working (nvidia kernel module loaded, Nvidia splash screen on X server startup, correct lines found in Xorg.0.log).
The Composite option is enabled:
Never-the-less, I still cannot enable the desktop effects.

I have my main box, Ubuntu 10.04lts, and I am trying to use remote desktop viewer to see the desktop on a Windows XP machine. The machines are side by side The Ubuntu box is hardwired to my network router, and the XP machine is connected via wireless. Both get to the internet fine, and I can ping the Ubuntu box from the XP box. But, I cannot ping the XP box from the Ubuntu box, and Remote Desktop Viewer won't establish a connection to the VNC server I have running on the XP box.

When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.
Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.
I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.

OpenSuSE 11.1 updated on Saturday to all of the latest patches and stuff. I was a bit behind, so quite a few things got updated. Most of them probably don't matter for this problem.
Prior to Saturday, desktop effects were working fine. After, they don't. Gnome still works ok, but attempting to go in to the "Desktop Effects" configuration just hangs for a minute (spinning "wheel" cursor) then nothing happens ("arrow" cursor returns).
Looking at things via "ps ax" I can see that clicking on "Desktop Effects" starts process(/usr/bin/python /usr/bin/simple-ccsm).
Running this from a CLI produces:
After which nothing happens and I have to hunt down the PID and kill it.
Searching for this "tuple index out of range" error, I found a couple of 2008 references, but those are for much older version so I'm thinking that they're probably not relevant. Nothing else seems to apply.

I have just installed linux 10.10, I want to use vnc on my another computer to access my desktop using remote access. When I navigate to Remote esktop Preferences. Your desktop is only reachable over the local network. Others can access your computer using the address localhost, no ip address. this is not working.

I have a local network in which are two boxes. The first one has Fedora 8 installed and updated regularly and runs an Apache2 webserver. It also has vnc-server activated.
The second one had Fedora 10 installed along with a vnc viewer so that I could access the first box from this one. The first box has the VNC host name of 192.168.1.67:5.
I had had no problem with this VNC setup until I replaced Fedora 10 with Fedora 12. Initially I was happy to find Remote Desktop Viewer had been installed as part of default installation ( Application > Internet ). But it did not take too long before I got disappointed that this thing failed to work.
No sooner had I connected to the remote box than Fedora 12 kills X-server and logs out displaying a login screen. It seems as if I had killed X-server by issuing a keystroke of CTL-ALT-Backspace, which has apparently been disabled in Fedora 12.
Edit: By the way, I am still able to connect to the Fedora 8 box from a Windows Vista box via TightVnc viewer.

I have a PC installed with Fedora 11 and I want to use this machine headless as a music server, my amplifier is connected to this machine. After a normal installation I've changed the default runlevel from 5 to 3. I can connect from a client, using FreeNX, to this machine and I get a normal Gnome desktop. So far so good.
The problem is there is no sound. But when I log into the machine directly, still in runlevel 3 and execute the script /usr/bin/start-pulseaudio-x11 an make a new remote-desktop connection there is music. Is there a way to make pulseaudio working in a remote desktop.

Wired and wireless networking have been working flawlessly for years on my HP Compaq 6710b laptop. Several weeks ago, after an automatic update via the update manager, my wired network stopped working. I did not notice it directly, since my wireless connection took it over. I only noticed it when I had to work in an office where I didn't know the wireless password.Since then, I have been trying several things and searched several forums. It is hard to find any troubleshooting information about wired networking, as most of the problems seem to occur with wireless.
I did verify that there is no hardware problem. My laptop is dual boot and when I boot the other operating system, the wired network works without problems (as does the wireless.)My Ubuntu version is Ubuntu 10.04.1 LTS. My kernel version is 2.6.32-25-generic i686. I hope anybody can help me getting my wired network working again.

pulled the wireless USB adapter out of the back of my laptop when I was using it. I plugged it back in and it can see my wireless network, but it can't connect. Everytime it tries, it just shows the connecting icon on the top bar for a few minutes and then says that the network has been disconnected.
I've tried uninstalling and reinstalling the USB adaptor, but nothing I've done seems able to fix the issue. Anyone know how to fix this?
The USB adaptor I'm using is a Trendnet TEW-424UB

I have a Thinkpad T400 notebook that dual boots windows 7 and Ubuntu 9.04. My wireless has worked both in windows and ubuntu for the past several months. However 2 days ago, the wireless in ubuntu stopped working. I think this may be a result of trying to set up a static eth0 connection between my laptop and an embedded board, but I dont see how messing with eth0 would stop the wlan from working.
Symptoms: When I left click on the network connections icon in the tray, all it lists under "Wireless networks" is "device not ready". Needless to say, there are no networks available to connect to. Also the wireless is working fine under windows.

Last night I was trying to get my printer working, and when I rebooted, I lost networking and sound.I am currently booting on a live CD, and sound and networking are fine-- so it can't be a hardware issue (obviously). I must have inadvertently broken something, but I can't figure it out.I have tried restarting networking, but it doesn't respond-- it says stop/waiting or something like that.I can't access the sound preferences-- it says waiting for sound to respond (or something like that).
When I reboot, sometimes I see a terminal window with the same line scrolling very, very quickly-- something about waiting for USB. Additionally, the system is very slow to respond-- clicking a menu item can take a long time for it to appear, etc.What could have occurred, and how might I troubleshoot it?

Just recently the wireless stopped working on Ubuntu 10.04. The machine is AcerOne AOA-150. I did notice recently the wireless would stop working, and I would need to either 1) reboot 2) switch the wireless off by moving the switch from left to right in front of the laptop.
However, this time nothing is working. I've provided some detail and if more information is needed, let me know.
LSPCI:
00:00.0 Host bridge: Intel Corporation Mobile 945GME Express Memory Controller Hub (rev 03)
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03)

Been searching for hours and looked at several other threads but still can't figure this out. We have 4 folders being shared from a Ubuntu 10.4.2 LTS Server using Samba. A couple days ago two computers in the office lost access to these shares. The other computers in the office are fine. So far as I know nothing has changed on the server. I can putty into the server still but I can't map a drive or open a window through run (\server_nameetc).
I've also tried disabled iptables on the server and windows firewall on the the windows xp machines. Still no luck. What am I doing wrong? Like I said, so far as I know there have been no changes to the server whatsoever. One day it was working and the next it just stops.

I've started to set up a server at my house, where I eventually want to run it headless, and I can just VNC in from my other Desktop. I installed Ubuntu 10.10, setup remote desktop on the server, and from there was able to do any work remotely. That was nice. I turn the computer off at night, and the next day when I was going to work on it, I cannot VNC in anymore. One day passed, and now every time I try to use VNC it comes up with "Failed to connect to server" I also set a static IP address on the server too, so I know the address isn't changing every so often.
