Ubuntu :: Skip "low Graphics Warning" After Boot On Remote Machine
Nov 3, 2010
I have a headless Ubuntu fileserver running 10.04LTS which is tucked away in a place which can be a bit of a nuisance to get to. I connect via ssh and tunnel VNC to local port 5900 for administration. When I setup the box originally, I selected the nvidia drivers through the restricted drivers option. However, occasionally after running "apt-get upgrade", X11VNC seems to fail to connect to the xserver.Twice in the past, after connecting a monitor to the device it has been stuck on a prompt complaining that it is operating in low graphics mode. If I skip this prompt to get to the desktop and then select the resticted drivers option and select the recommended nvidia driver, the problem doesn't seem to arise again. Obviously, being the third time this has now happened I'd like to find an alternative to draggin a monitor and keyboard to said awkward place and wondered if anybody knew of a workaround?

when changing /etc/network/interfaces and adding incorrect variables. next time you reboot the system it won't start. in the past with 9.10 & 9.04 ubuntu used to ignore these errors in the file and continue booting. allowing us to correct them later. is there anyway to skip these boot errors?

I'm trying to set up a machine without a monitor. It has a video card in it but it won't have a monitor connected.Basically I want to press the button on the front, it boots up and I can remote desktop onto it from my main machine. I'm assuming this means it needs X.The problem I have is that with no monitor attached, it boots but complains about "low graphics". I only see this complaint after I re-connect the monitor cable. My remote desktop from the other machine works fine until I come to shut it down whereupon it just sits there presumably waiting on the display that's not connected for someone to fix the low graphics "problem."
Is there a way to stop it moaning about low graphics? Or, better yet, have a machine without a video card at all yet still be able to remote desktop onto it? Is there some kind of virtual framebuffer version of X I could use that would allow this?

I am trying to perform a hard drive installation of RHEL 5.5. I specify the installation method and the partition and directory holding the ISO image in /etc/grub.conf
Code:
However, I am still presented with the "Installation Method" and "Select Partition" screens when anaconda runs. Is the syntax of the repo boot option correct?

I do not know if this is really something I should worry about. I am running Debian testing on my laptop (HP Pavillon dv6). Today, the aptitude update---aptitude upgrade gave me a new kernel (2.6.39). However, if I boot with that kernel, I get a warning (do not know if that is the way I should call this) telling me that the machine failed to get the i915 symbols so turbo graphics will be disabled.I have not done any serious test, but at first sight I do not notice any difference performance-wise with respect to the previous kernel. what am I supposed to do to fix this?

After updating Ubuntu 10.04 I'm getting this error message. "Ubuntu is running in low graphics mode. Failed to load the NVIDIA kernel module." I have a NVIDIA Geforce 220 video card and previously installed the NVIDIA drivers. All was working well until this last update. There are countless number of forum messages on how to fix this but my problem is compounded because when I get this message the machine appears to lock up.
It doesn't respond to any keyboard commands such as Ctrl-Alt-F1. I am not able to get to a command prompt at all. This was a fresh install of 10.04 so I believe it uses GRUB2 which automatically boots into the operating system with no menu. Is there a way to stop GRUB2 from automatically running the OS and giving me a menu? I really don't want to reinstall.

I'm wondering if it's possible to control a TTY on a remote machine via SSH. I'm aware of ssh's -t option, but it doesn't seem to do what I want. Basically, I'm thinking in terms of VNC-like operation, where the remote user and local user see the same thing, only instead of a GUI, they both see TTY1 (or 2, or etc). Is that doable, or no?

I have SSH -X working fine, displaying stuff that's running on the remote machine on my local machine. But how do I display on the remote machine? I did this many years ago on unix and seem to recall that this was either default or a simple case of setting DISPLAY....

I can ssh from my local machine (Ubuntu 10.4 64bit) to a remote Linux server. When I try to copy a file back to my machine (or just ssh to my machine) I get the following error - "port 22: No route to host".ifconfig on my local machine gives one ip address for "lo Link encap:Local Loopback" and one for "wlan0 Link encap:Ethernet"; I tried ssh both.I work on a laptop with a wireless router (which is also the modem)

I ran the following commands on my ubuntu desktop :
xrandr --output VGA-0 --mode 1680x1050
xrandr --output VGA-1 --mode 1680x1050
xrandr --output VGA-1 --left-of VGA-0
This gives me dual head. I have a second machine on the same 100mbps network that is also running Ubuntu. I want to run X on that machine and have it's X session as a monitor in xrandr, so I would add something like this :xrandr --output REMOTE-1 --right-of VGA-1Is this possible?

I am running a local webserver mainly for development. I have everything set up. The issue I currently have is that I cannot shut down the machine from the command line. I can issue the command but the machine remains on. I also cannot get to the desktop via VNC.The reason for this, is that there is no monitor attached so Ubuntu says that it is trying to run in Low Graphics Mode. I found this out as I plugged the monitor in to my server.So question is, how do I get around this? How can I set up Ubuntu to get past this, or do I need to install Ubuntu Server?

I'm having trouble displaying Xwindows programs on a remote machine. If I run "ssh -X newmachine" and I login and then run a program like xclock, I get the error message:
Error: Can't open display: localhost:10.0
If I run the same command to an anothermachine which is running Ubuntu 8.04 it works fine and xclock displays on my localmachine. If I run the command "echo $DISPLAY" on newmachine, I see:
localhost:10.0
Also, I have checked and xauth is installed on newmachine. What setting I have to change on Ubuntu 10.04 to allow remote display of Xwindows programs?

I set up a print server with a USB printer attached. I can remotely bring up CUPS and print a test page, but I would like to be able to add a printer in windows like I normally would. Add printer, network work printer and so on, but I am not sure how to implement this on Ubuntu server. Do I need to use IPP or do I have to share it out using Samba? Oh, my server does not have a graphical desktop, it is strictly console based.

I'm try to assess the viability of of setting up remote administration on a distant machine. Just for background, the computer I wish to administer is located on a boat in Southern Ireland while I'm in SE England. Sadly, the the boat operator is a far better fisherman than computer user and every now and then some rogue sensor numbers get captured by the boat's computer and these eventually need operator intervention. Anyone who has tried to talk a non PC literate user through correction routines over a dodgy mobile telephone while the said user is trying to operate mouse/keyboard in an Atlantic swell will appreciate the problem.
However, there is a fairly good mobile phone broadband signal available in the area so I was wondering if there was anyway I could set up a point to point connection with the boat over this medium. That would allow me to administer the machine remotely.

I have a VPS by my host running on a linux server, and they have given me SSH access. Is it possible to remote desktop into the server, like you can on Windows, so that I can physcially click on things rather than having to use SSH commands?
Surely this must be running on Fedora or Ubuntu etc. so there is some type of OS. You would probably have to install something on the servers end I suppose but just want to know if its possible and what the options are.

I have looked for clues in the sshd.conf etc. But I can't really find anything that give me a hint of why fedora 14 keeps blocking my access.I get all the way into the ssh interface.
login as: xxxxx
xxxxx@xx.xx.85.216's password:
Access denied
xxxxx@xx.xx.85.216's password:
Access denied
xxxxx@xx.xx.85.216's password:
So it's not a firewall problem and the port forwarding is working fine. I am using putty to access the machine remote.Anyone have any ideas of what I need to set in ssh or sshd.conf. I am expecting to login with password not with keys.

I have a debian system that's freezing in the boot sequence at "Setting system clock".Several sites I looked at recommended changing the init scripts to disallow hardware access to the clock. But, I can't boot! Is there a parameter I can pass to the kernel at boot so that it will skip init scripts?
