Ubuntu :: Running LiveCD Demo Version On Full/unstable System?
Jan 6, 2010
I have an XP laptop, currently running very low on HDD space and RAM capacity, waiting to be replaced. Very slow indeed. It recently had problems booting up, and now takes about 20 minutes to get fully started. Is it safe/advisable to run the demo version of Ubuntu from the LiveCD? I really can't afford to trash or crash my computer, it's got lots of important data on it etc.
I would like to run Linux Mint fullversion from a flashdrive. Is it possible and easy to set up. I have found how to basically create a flashdrive version of the live cd, but I would like to run the full version from the flashdrive.
I have a system built and running in exactly the basic configuration I want, with my recompiled kernel, extra packages, special drivers, everything works, life is good. What I want to do is take this exact setup and create an image I can copy onto a bootable USB stick. Is there a way to essentially take the contents of my hard drive and copy that onto a USB stick and then boot directly from that? The use case behind this is that I am building an embedded system of which I may have hundreds of boxes with identical hardware and software configurations. Instead of hard drives, I am going to use USB sticks for cost efficiency and maintenance. My idea is that when it's time to upgrade, I could just image a hundred new sticks and go out and swap them.
My issue is that a standard LiveCD install gets me maybe 25% of the way to a finished system. I need to recompile the kernel for realtime support with my CPU, add some fidgety drivers for some specific hardware, and install a whole bunch of additional packages. I suppose I could create a makefile(s) to replicate all the manual steps of the buildout but that seems like a lot of unnecessary complexity IF I can just image that running system as it is.
Checking the process table for the running sendmail, I would like to know the full path to the sendmail binary a la the ps -ef on a Sun or other servers. How do I get ps to give me the actual path, or should I use a different tool on my Linux servers?
So 2 days ago everything was all fine on my machine. Has been for about a month, but all of a sudden as of yesterday I have no sound, I am seeing IRQ interupts on boot, During boot I am seeing file system is not clean, , and swap space is being used for the first time while doing normal task, etc. These are 2 new hard drives in RAID 1 with ReiserFS. I should have used a newer FS but thats a whole other argument.
Anyways here we go. The system is Debian Lenny amd64 Physical RAM 4GB + 6GB swap /var/log/messages

My netbook model is Asus eeepc 1201n and I'm running Ubuntu 10.10 but I had the same problem while running 10.04: wireless disconnects and reconnects every 30 minutes or so and, after this has happened for a few times, it doesn't reconnect and keeps asking for the password.
I've been running the Evolution mail system under Fedora-15/KDE for about a month now, and it has some very serious problems. I just noticed that it is available for SUSE, and figured that since KDE is the principal desktop supported by KDE the SUSE version may be fixed. Before I go through the very tedious process of getting the SUSE version to compile on Fedora, I'd like to know whether anyone has seen these problems with the SUSE version of Evolution:It ignores font control from the KDE Settings->Applications Appearance window, both KDE font control and GTK+ font control, also its own internal font control window.
It has trouble sending messages to an SMTP server, sometimes taking a l-o-n-g time, sometimes timing out. This can be temporarily cured by restarting it It crashes when a filter attempts to refile an outgoing message. It often asks if I want to recover messages that have never been lost. It often locks up receiving mail from a remote POP3 server. I can live with these, except for items 1 and 2, since I have workarounds. If you are fairly sure that you have not seen these problems with the SUSE version of Evolution
My work machine crashes 1-3 times a day, and I often lose work. This is getting very frustrating--I've never known a Linux system to be so unstable.
When it freezes, I can still move the mouse around. I believe it's also still doing some background tasks, since files have finished copying before and my music will still be playing, if it was before. But the mouse cursor doesn't change, and it's totally nonresponsive.
The trouble is, I don't know how to diagnose this problem, to tell you something less vague. I might be able to check, to see what's going on? The problem usually comes about when I'm doing something--either loading a new web page, or starting a new program, or even when I just hit a button. Otherwise, I'm just stumped.
I recently assembled a new desktop computer, the following is the hardware details
CPU: intel core i7 2600 Motherboard chipset: intel Z68, GIGABYTE GA-Z68A-D3H-B3 Video card: Geforce GTX 560 Ti
I tried to install ubuntu 11.04 i386 and X86-64 version. Both of them are quite unstable.The system is easy to crash because of network problem and the internet connection is extremely slow. I also install window 7 in the same computer while the wired network is doing well.
I recently bought 2 RAM modules, 1GB each, to upgrade my system replacing the 460 MB I had before.Once replaced, I started my system and checked with 'free -m' that the system can see them and uses them.But my system became unstable, and it gets stuck (hangs) after 20-40 minutes and I have to do a hard reboot to get it back to work.
Also flash-player crashes few minutes after playing no matter which browser I use.
I have made an upgrade after installing my new RAM and have the latest Kernel installed.
I'm trying to run the subj on my desktop but all the time i get this : "The installer encountered an unrecoverable error. A desktop session will now be run so that you may investigate the problem or try installing again." I hit ok and pc throws the cd out, and thats it; Rebooting gets me back to win 7.
Ive been searching for days and days trying to get this monitor to output in 1366x768 on Ubuntu 10.04. I knew it was possible, i did it late one night about a month back, but my system became unstable (not due to the resolution, i had setup a firewall to block all incoming till i unlock it, then another application to connect before i log in, and somehow it managed to lock out my keyboard on the login screen AND the recovery console, so i decided to just reinstall it)
Anyways, i found out exactly how to do it (for the Acer 183h that is). Ive spent about 48 hours total pouring through documents and found the documentation for nvidia-settings (easy find, i know, i was hoping to find an easy solution like what im typing up)
So, i figured out I could use Nouvaeu to get the proper settings (since all the modeline calcs dont do 1366, only 1360.) What i did was i went into the log file for the xorg,conf right after i installed, and in there somewhere near the middle it says what the timings are.
And i inputed that modeline into the monitor section, like so:
One of the two EDID commands is an old one, i just left it in there so when i was searching throught the xorg log i could find the section really quickly.
(BTW, im not sure if these timings are 100 accurate until i reboot my livecd and check, but im sure thier pretty damn close, and my monitor hasent exploded yet if your worried bout it, grab your livecd, open your xorg.conf, and it "should" be in the monitor section)
Next, i had to input all the Options to not search for different modes into the device section:
And finally, i had to set the screen to output the 1366x768, entering Modes "1366x768_60_0"
In the Modeline and Modes section, its VERY important that you have it in the format i have it in. The Modeline name MUST be completely custom, by adding either letters or extra _0.
And thats it!
Reboot, restart X, whatever (I prefer reboot, gives me time to ponder ) and you should be good to go.
(I know this may seem like a beginners knowledge type of thing, but im a beginner, pretty damn bright, and it still took me 4 days So, if this helps just one other person, ive done my part)
Im also pretty sure this method will work with other wide screen monitors, as long as you get the timings off Nouveou via LiveCD or installing the driver.
EDIT: This thread has taken a different turn, please go down to viewtopic.php?f=30&t=64242#p370832 Below is I originally wrote, now totally irrelevant.:D I am delighted/bored with my one Debian Squeeze install, so I've decided to free up a partition to play with another configuration of the universal OS.At the moment I am liking the looks of the supposedly not so unstable Sid; what's the ideal download/install path to get Sid up and running? Is it:1) I already have a live Squeeze GNOME DVD lying around; should I install that again and upgrade to Sid?
I been trying to figure out why after updating to the newest version of ubuntu the system didnt work anymore, but now my main concern is trying to recover files that I had on my computer, how can I do this?
I would like to download a complete Ubuntu Server on a CD/DVD to be installed on a server where there is no Internet connection in a developing country (Africa). Please let me know how I can download a full version of ubuntu Server on a CD/DVD.
I downloaded Ubuntu and was hella pumped to use it.. I downloaded it, burnt it at a 4x speed (slowest I can) I did a clean install and made it the only OS on my Hard Drive. After installing it said I didn't have connection. After a good 3-4 hours, I tried every option, I even got it to say I was connected but I still had no Internet connection. I put in my Windows 7 disc to go back to what I originally had. BUT I couldn't install it to a hard drive that wasnt formatted at NTFS, I guess Ubuntu changed my HDD. So, I put back in my Ubuntu disc and clicked 'Try Ubuntu'.. Found out that the TRIAL gives me Internet but the full version does not. I copied down the configuration that the Auto Eth connection had, and went back to the full version - I already had in the exact same configuration. So im here with a trial on my computer, can't download anything or install anything. I cant go back to Windows 7, and I need the disc in to use my computer.
I installed Ubuntu on to a usb hard drive now without that hard drive plugged in i cant get to my windows(it goes to grub recovery). With it plugged in it lets me pick witch OS to use. How do I get it to just boot right to windows when its not plugged in?
I have Centos 5.3 on our server When I log-in in webmin I have a message "Warning - Your system is actually running CentOS Linux version 5.3." In the next line I have a button "Update Detected Operating System" My question is Do I need to click the link and update Detected operating system? If I do, is it going to change any configuration on our server?
My boss is asking me if there is any way to run a full version of Ubuntu from a flash drive without installing virtualbox/vmware on a windows host. I've been searching pendrivelinux.com and really haven't found anything. Can someone point me in the right direction?
I recently installed F12 on my main notebook and ever since the fan has been running at full speed (or near full speed). According to the 'sensors' command I usually have temperatures between 50-70. I didn't have this problem before the installation.
I have a requirement where I want to extract the full name of the process running in my box. I tired various options of ps. The wide option gave me the full command but that contains command, the interpreter and also the arguments passed.
XX XX XX XX XX XX /usr/bin/sh /path/to/exe/myexe.sh arg1 arg2 arg3.
Is there any way from ps or any other command I can extract the full name of the command
Using the ubuntu live cd 9.10 I get weird error messages when shutting down the system, sometimes it is this one: device removed: /freedesktop/Hal/devices/net_80_00_60_0f_e8_00
Other times it is bunch of errors saying something like: i/o error/end request/dev/sector ****, with all different sector numbers.. These happens even when I have not installed anything, not using any flash drives etc...
I am having trouble installing HPLIP (all versions) onto my system. When I go to configure the source code, it goes into a loop checking for a BSD install. So, to get around this I want to try and install HPLIP onto the system via a livecd. How would I go about doing this?
I am using the Ubuntu 7.10 Livecd with some modifications I did, and I wanted to update the base-system to the most recent release of Ubuntu. Once I have chrooted into the custom ISO's root filesystem do I use:
Code: apt-get update apt-get upgrade apt-get dist-upgrade or
Code: aptitude update aptitude upgrade or neither?
