Ubuntu :: Pared Down Command Line For Faster Boot
Jul 8, 2011
Would be possible to have a dual boot with Ubuntu only loading the things necessary for command line use of emacs?
I thought it might be good to be able to take notes for class on a quickly booting command line. (It has the added benefit of being less distracting)
Does it work like that? Could a pared down command-line only install be sufficiently faster on boot-up? Might another flavour of Linux be more suited to the task?

Out of curiosity and stupidity, I configured 2 extended partitions to LVM in gparted. Now, I can't boot into X window, and there's only GRUB command line during boot.

Is there something I can add to my "menu.lst" file to give me the option to boot Ubuntu into command-line only without needing to edit system files every time I want to switch

Despite my best efforts to have them use debian or ubuntu server, a client wanted ubuntu 11 on the new server they built. It runs all the services I need it to, but would be nicer to have that server boot to command line. It seems nothing is going to work. I have tried:
1. changing /etc/default/grub to "quiet splash text"
result: blank screen
2. sudo update-rc.d -f gdm remove
result: no change
3. echo manual | sudo tee -a /etc/init/gdm.override
result: blank screen
Has anyone gotten Ubuntu 11.04 to boot to command line out there?

EDIT: sudo /etc/init.d/gdm stop worked, not sure why it did not before. Sorry for the whining!
I need to boot Ubuntu into a non-x, command line mode. So I can install an nvidia driver for my new GeForce GTX 260 (I had a GeForce 7900 running on my Ubuntu system using the synaptic open source 185 driver for nvidia, but there is no driver except the one I downloaded just now from nvidia's site for the GTX 260 card). That requires there be no X session running, not even in a separate domain so to speak. There is no rescue mode in Grub2. Recover mode in Grub still boots an X session (Gnome). Alt+F1 appears to be a clean command line terminal but even that does not work because the nvidia driver installer script sees through that ruse and knows there is an active Gnome session. I tried sudo /etc/init.d/gdm stop and that did not work. I tried ctr+alt+backspace and that did nothing.
What can I do? I tell you some days linux is just too frustrating, about to just toss the baby with the bath water and go back to Winblows. Bought a new graphics card today, and here I am stuck not being able to even install the driver from a command line prompt, geesh.

Just installed Ubuntu 10.04 LTS as a VM on MAC OSX. I want to auto boot to the command line, but the GUI keeps coming up. I ran "sudo update-rc.d -f gdm remove", but it didn't work.

I have used the below command to do that successfully for the previous version of ububunt, but this time I failed to do that with Ubuntu 9.10. I know I can do that manually by "sudo /etc/init.d/gdm stop" command. I try to change the name of /etc/init.d/gdm files, but the problem still exist.m"sudo update-rc.d -f gdm remove"

I just installed a fresh install of 9.10 on my amd64. when it starts it locks up right away. i know that this has to do with my nvidia card. i've had to do this in the past. but since it locks up i have no way to get into the command line. ctl-alt-F1 does not work. is there a way to just have it boot right to the command line without loading up gdm?

I did a clean install of Lucid from the alternate installer, onto a generic Intel/Celeron PC box. I used a command line only install, and used the entire hard disk; there's no other OS and no other partitions on the disk. Install goes along and finishes fine, reboots, and I can log in. But if I call sudo reboot, or shut down the machine then restart it, the boot process hangs. I see the POST screen, then a flashing cursor on a black screen for a few seconds, then the monitor goes into standby. I see no messages or any kind of output to the screen. I get the same problem using the Lucid Server installer and also when installing on a different box (Dell Intel/Celeron). I also tried running all the updates after install but before any kind of reboot...same thing.
This only seems to be happening using a command line only version of Lucid. Lucid GNOME/XUBUNTU install and work OK on both boxes. I can boot from a CD or USB key, but not sure where to look or what to check.

In dealing with the Nvidia Powermizer, I have to set it to "Prefer Maximum Power" mode from adaptive mode in order that I can avoid laggy in using my GUI. However, it doesn't save this setting so I have to manually tweak it everytime........
Someone on the web taught me to use the following command line:
nvidia-settings -a [gpu:0]/GPUPowerMizerMode=1
running it in the terminal it will set to the mode I want.
Would I be able to make my computer run the above command in terminal everytime it starts? I tried to put the command in the start up applications and it seems not working.

I don't recall my Ubuntu password.**
I found instructions regarding recovery.
They involve pressing Ctrl-Alt-F1 while booting the Ubuntu live CD.
If I allow the live CD to boot, I arrive at a Ubuntu GUI.
However, if I press Ctrl-Alt-F1, the monitor (HDMI TV) goes blank and indicates "no signal
correcting the password from a GUI (can I just go to a command prompt from there somehow, and work from that command prompt?) or getting my video to display when I press Ctrl-Alt-F1?
** (I remember trying to set up the system with NO password).
It's absurd to require one.
Especially so if a person with a live CD can simply change it (I guess at least the change would be detected).

What is the simplest way to boot to command line rather than gdm ?
I've seen post to change

to
id:3:initdefault:
and
update-rc.d -f gdm remove
update-rc.d -f kdm remove
update-rc.d -f xdm remove

I am following an instruction on the Internet to set up a timer=1. "You can force use of the timer interrupt by using the timer=1 module arameter (or oprofile.timer=1 on the boot command line" When I type "modprobe oprofile timer=1" at the command line, I got a warning message saying that "Deprecated config file /etc/modprobe.conf" So i want to try other way by setting it at the boot command line.

I recently updated, and now when I boot it only goes as far as grub command line. There is no grub menu. The computer is a Dell Inspiron 8600 laptop with only Ubuntu installed -- no dual boot, no weird partition schemes. Originally installed Ubuntu 09.04 on this computer, upgraded a couple times and it currently has (had) 10.04.1 LTS running. The update should have upgraded from kernel 2.6.32-23 to 2.6.32-24. I can boot with a live CD and mount the hard drive. The drive seems fine, so it appears to be simply a grub config issue. I have to boot with live cd to get online to check for potential solutions. So I'm taking some notes on how to use grub.

Running Ubuntu 10.10. My desktop environment is screwed up and won't let me use the keyboard or mouse at the login screen. How can force a command prompt during boot?
Here's a method:

It used to be with (old) grub you could hit a function key and add a runlevel option to boot a console, but I don't know how to do this here, wanting not to edit the grub config file, as seems the only apparent option: I'm trying to boot into SimplyMepis where there is no rescue menu option, so need the prompt?

2, Updated inittab

My Wubi installation of Ubuntu (version 9.10, I think) that I recently installed was working fine at one point, but now it isn['t. I select Ubuntu instead of Windows from the Windows boot loader, but instead of getting the usual menu of different linux versions (I think 2, as I updated it at same point), and Windows, I get the GRUB command prompt instead.I've looked at th2e Wubi Guide (https://wiki.ubuntu.com/WubiGuide), and I've followed the instructions for "How can I access my Wubi install and repair my install if it won't boot?", but that reveals no problems.For the record, I'm fairly new to linux and ubuntu, but I'm good with computers generally. The main operating system on my computer is Windows Vista, but I'm currently typing this from a Live CD of Ubuntu 9.10. The virtual disk (root.disk), is currently mounted as vdisk, as indicated in the Wubi Guide.
Ideally I would like to get Ubuntu to load as it used to (with a menu). However, if there is a way to boot from the GRUB command line that would be good too. I'm not at all familiar with GRUB, and the commands I've tried (boot and linux, I think), get errors saying no kernel specified, or loaded, or something like that.

I'm trying to automate OS installation. I've setup PXE and able to do network installation. For installation, I'm changing the BIOS boot order to boot from network.Once the OS installation is over, I need to manually change the BIOS boot order to boot from hard-disk. Can BIOS boot order be changed using programs/command-line so that i can eliminate human intervention in the installation process by changing back to the original boot order by program/commands?

I've recently had trouble reinstalling my Ubuntu system as I was getting various unusual errors as described in my old thread here. I thought it was probably something to do with my RAID-0 array which was pre-installed on my laptop from purchase being corrupted or something like that (if it's possible). I decided to simplify things for myself (not understanding RAID arrays much) so I just removed the RAID array and installed Windows and Ubuntu on the now separate hard disks. It worked fine.
I noticed quite a significant performance drop, however, with even Ubuntu boots taking longer than 30 seconds despite my laptop being both high-spec and only a few months old. Windows, as you can imagine, was dreadfully slow. I wasn't entirely convinced that this was entirely due to the loss of the RAID array - as even low-spec laptops with presumably no RAID arrays are supposed to boot Ubuntu in under 30 seconds apparently - but I read that RAID-0 arra

I'd like to say I'm very impressed with Fedora 11. I'm a long time Linux user and I've tried many distros. But, I usually keep only the best on my laptop. For a long time that was Ubuntu but, I think Fedora 11 has made some key improvements over Ubuntu and I'm eager to switch. The problem is: I haven't been able to run Fedora as anything other than on the Live CD. Everything works perfectly and it installs but, when I reboot, Grub begins. Instead of booting, however, Grub drops into its minimal shell and gives me a command line.
I've tried installing it a number of ways now and have read much about the problems with Ext4 on Grub and took special care to see that Grub has its own, separate, /boot ext3 partition. Even then, no luck. My hardware should work fine. I've got an HP DV-5 with 4GB RAM, AMD Turion 64-bit dual-core @ 2 Ghz, and an IDE 250GB hard drive. I'm working with the 64-bit Fedora 11 Live disc with KDE as the Gui.

I've got an install of CentOS 5.3 in a VM which was installed without X or Gnome.I've added X (yum groupinstall 'X Window System') and Gnome (yum groupinstall 'GNOME Desktop Environment) and can now run startx no problem.However on boot I get a command line login rather than the graphical login screen one normally gets if Gnome is included at install time.What do I need to do to get the graphical login after boot?

I was unsatisfied with the 40second boot time of lucid and was searching for a solution for a while but didn't find anything yet. But today I found a way to boot 10seconds quicker.Lucid is installed here as suggested by the installer:
Primary rootpartition (/dev/sda1)
Logical partition (/dev/sda4)
swap (/dev/sda5)

I am using Ubuntu Maverick on my Eeepc 701, and everything is working quite nicely. Since I only have 4GB SSD drive, my setup is that the LiveCD is booted from the SSD, while my 'casper-rw' partition is on a 4GB SD card. I have 2GB of ram and do not use swap. I am wondering if there is a way to somehow cache the results of the hardware probe and configuration, and insert the cache into LiveCD by remastering it. The idea is that less time will be needed to boot, since everything that was found from the first boot was saved.
Of course this would mean that particular modified LiveCD wouldn't reliably boot on anything other than my system (or one like it), but seeing as how my hardware won't change in the future, it isn't a problem.
Is something like this possible? I'm not afraid of recompiling a kernel or rebuilding an initramfs if needed. A possible alternative idea to accomplish this would be to boot up the vanilla LiveCD as normal, configure a swapfile, hibernate, then inject this swapfile into the LiveCD image.
This way, every boot would automatically just be resuming from hibernation. This could potientally mess with the casper-rw partition, but that is something I would worry about later (and I am not opposed to just eliminating the casper-rw partition altogether and running off ram each boot).
The other problem might be that the swapfile would probably need to be the size of my ram (2GB). Chances are, after a fresh boot my ram will be mostly empty, therefore would it be possible to compress the swapfile (like swapfile.gz)? I will be looking into either alternative, but I was hoping to get some opinions / ideas on how to accomplish this (or whether it has already been done!)

I have an Ubuntu Server 10.10 install on a VIA C7 chip. It seems to pause for about 5 min on a USB component.
It is a fresh install, here is a snip from my messages log code...
My KB is USB, so I would rather not disable it if at all possible. The next time I can take it down, I will test disabling it though...
