I'm trying to get a remote viewer / VNC on a PC without a monitor. The default one that comes with it seems it wont work without a monitor attached (including that every time I connect, it asks me to enter the keyring password). Is there a way to get VNC server installed that it will mirror my desktop?
View 9 RepliesI just installed ubuntu 9.10 server edition (twice, just to be sure) and the installation ran fine, but when I try to boot into the system, i get past the BIOS loading screen then my monitor just goes into power saving mode and I can't get it to see a signal from the PC. I know the OS is running, because I can ssh into it from my laptop, and I know the monitor works, because that machine had a windows OS on it before and that worked fine with the same monitor. I had thought it might be a graphics card thing with ubuntu trying to push out at a resolution not supported by the monitor, but I find that unlikely as it's brand new this month. If anyone has any idea of something I can try to diagnose the problem, that would be great. As I said, I still have ssh access to the PC, so I can basically try anything on it that I could if I was physically at the box itself.

I've got a headless server (32 bit 9.04/9.10, can't remember) that started refusing SSH and HTTP connections a few days ago, and I'm just getting around to hopefully fixing it. The problem is that I can't even connect to the darn thing. I've plugged in a mouse, keyboard, and monitor, but the monitor tells me that it has no signal. I know the monitor works with the computer, as I used the same one to set up the server.
Just for kicks, I even tried to put in a live CD, but that didn't help. Any ideas on how I can connect to this thing?

View 4 Replies View RelatedI have an old computer (Pentium 4) without a monitor. To make the most of it I installed Ubuntu server on it and have been using it for almost a year. A couple of months ago I don't really recall what I did but since then it doesn't start-up unless a monitor was plugged in.
I've tried pinging it but it doesn't respond when no monitor is plugged in. meaning it's not even booting correctly.

It will be quite literally bare, consisting of motherboard http://www.axiontech.com/prdt.php?item=88615, CPU, RAM, power supply only (won't even have case). I'm working as contractor at 3M and would like to reduce my baggage when I move.I will probably boot Debian on USB flash and access the machine with SSH, but my main dilemma will be how to setup the system while trying to avoid buying a keyboard and monitor. I can test the USB boot on my laptop, but I will need a way to diagnose problems. Beeping the speaker so I know the system is at a certain state would be a clumsy solution, assuming the motherboard even has a speaker.
View 9 Replies View Relatedwhen the server is getting overloaded with users. At present I run the server mainly as a proxy server with about 100 users. The bandwidth at the data centre is 100Mbps connection with total bandwidth used last month = 17431.16 MB
I would like to add a VPN in future but feel that this might overload the bandwidth as instead of it just being web traffic it will the entire client TCP connections. I would like to monitor this before it gets to the stage where users are complaining but not sure how to gauge whether the proxy is being overloaded. It is used mainly for video traffic.

I 10.04 32bit server edition on a box I had lying around, set it up for samba+upnp, and everything was going great.
When rebooting, the server now turns the monitor off, and I'm not sure if anything's loading. I see the initial dell splash screen, and hear the hard drive start to run, and then the monitor goes into standby.
I am running a server that is mostly headless, but does run the Gnome environment (I have ubuntu-desktop installed). I usually administer it via VNC over SSH. My problem is that when I reboot the system over SSH, the system fails to fully load the GUI, which prevents me from connecting via VNC (although SSH still works).
When I connected a monitor and rebooted, the system booted up fine. It appears that the GUI will not load without an attached monitor, which never happened before in previous Ubuntu versions. I do use many commands but prefer a GUI for certain tasks and visualization of my work since my system has the resources to spare. Running Lucid Lynx
i done desktop config in ubuntu server 11.04 and connected via tightvnc,uvnc and in remote desktop viewer from another ubuntu machine also. I am not able to access(connect) the server in GUI mode(when monitor is removed) but i putty is working fine in cmd line.
