Ubuntu :: Multiple OS On 1 PC Hardware?
Sep 1, 2011
I work for a technology company manufacturing PDA's.
We want to setup a test environment of multiple PC configurations (Linux, Mac, Windows - XP, Vista, 7 and both 32 and 64 bit platforms).
I have played with GRUB a little and got that working with Windows XP Pro for dual boot options on Ubuntu.
I am wondering if it is possible to setup more operating systems on the 1 computer hardware (could install more hard drives if required) with GRUB. Not sure if PC hardware can take installs of both 32 and 64 bit platforms or not.
Or is it better to have 1 PC for each OS? What are the advantages of that? Obvious disadvantage is cost of hardware.
Or is it better to setup VirtualBox for this sort of environment?

We are working on a project to create a display wall of 8 monitors arranged as 2 high by 4 wide. Each monitor is connected to a single machine and all machines are networked with a master machine with its own, seperate monitor.
Our goal is to get the 8 machines to share a single desktop, with the master machine acting as the server. We have looked at using Xinerama or NMM, but we are unsure about how to get started configuring the multi-machine, multi-head display.

I often use the rpl command to make changes to multiple html files at once. For example:
rpl -R '<br />' '<br /><br />' mydirectory However, I haven't been able to figure out how to change multiple lines. For example, let's say I want to change all occurrences of :
<br />
<br />
to:
<br />
I've tried
rpl -R '<br />
<br />' '<br />' mydirectory
but that didn't work. how to do this with rpl or some other way?

I'm trying to connect one computer to two others in an ad-hoc infrastructure.
[computer 1] ---- [computer 2] ---- [computer 3]
computer 2 is running Linux and has a single NIC wlan0. I want to it to connect to both computer 1 and computer 3 so each computer can talk to the other. No switch is available so it needs to be an ad-hoc setup.

I am to rename all the files within a directory (which contains multiple subdirectories) recursively without invalid characters.
I tried the coding posted above.
find . -type f -printf '%p
' | while read file; do
oldfile=$(basename "$file")
newfile=$(echo "$oldfile" | sed 's/[^A-Za-z0-9_.]/_/g')
if [ ! "$newfile" == "$oldfile" ]; then
echo mv "$file" "${file%$oldfile}$newfile"
code....
but I get an error on both of them stating "find: bad option -printf find: [-H | -L] path-list predicate-list"

I'm starting to have A LOT of opened windows in my machine. Sometimes within a project, I have e-mail/task management/personal e-mail/twitter, and a lot of different opened applications/terminals in my Linux workstation.Sometimes it would be interesting to have different workspaces to projects instead of this configuration I have nowadays that are classes of work (bad name, I know, but I think you got the idea).I'm starting to think about using two monitors: one with Corporate Management, Work and Personal. The second monitor is only the development state: each workspace here is about a project being worked on instead of groups of works like before. A workspace may be implementing different classes for example.
My question is: I just want to change to a second monitor using the mouse. I want to still be able to change workspaces in the same monitor using keyboard shortcuts. The keyboard shortcuts wouldn't change monitors, just worskpaces on the same monitor. All the tutorials I read (like this one) only tells how to use multiple monitors but doesn't answer my question about keyboard shortcuts.Does Linux (Ubuntu 10.04 Lucid Lynx or Debian 5.0.5 Lenny) support this envisioned setup (Different workspaces in a way that keyboard workspace switching only works in the current monitor) ? If so, how?I haven't tested this setup, that's why I'm asking. In this question the user says it works exactly how I want it to behave, can someone else confirm it?

I have an old pentium 3 computer that has ~7 NICs installed. These NICs are attached to modems and other networking equipment. According to the linux ping page on computerhope.com, it seems that one could send a ping from a certain specified NIC. How would one go about this?

I'm looking at setting up a couple automated systems: Here are a few examples:
* Internal accounting system to download and process emails
* Public web server to visit
I could put each system on its own separate box -- for example, it's generally good practice to separate anything that external users have access to (such as a webserver) from internal processes such as accounting. Now, rather than dishing out the money for two separate servers, could I get away with just installing new instances of VMWare on the same box for each system?
To give you an idea, these are not large scale computationally sensitive systems. The accounting one is simply downloading and tallying emails, and the latter is just a webserver with maybe 5 hits per day on a good day. I could definitely pick up a new box for say $50, but I wanted to know the general practice of using VMWare on the same box versus two separate boxes.

I have a CentOS 5.3 box with three network interfaces in it. Each interface is attached to a separate VLAN and I want traffic to stay on each network segment.What I can�t figure out is why I cannot get each interface to have its own gateway and everything gets sent through the default gateway.The basically takes my possible 3Gb total bandwidth and throws it down a single 1Gb pipe.Then on top of that, if I take down the interface (ifdown) that has the current default gateway,I loose contact to the other two interfaces.When I look at the routes, each one of the interfaces shows the gw as 0.0.0.0 and defers to the default route. So I delete the route and try to add a new route with:
[root@testsan ~]# ip route add 10.1.15.0/24 via 10.1.15.1 dev eth2
but end up with the error:
RTNETLINK answers: Network is unreachable
[root@testsan sysconfig]# cat network
NETWORKING=yes
NETWORKING_IPV6=no[code].....

When i start my Ubuntu it doesnt go directly into xserver/desktop mode. This is because my machine is very slow. Therefor i exclusivly use the terminal. I only hate the fact that there is only one terminal and i cant switch between them. ctrl-shift-F2 doesnt work. How can i use multiple terminals before having logged into X?

I was looking for a solution to watch HDTV quality videos on multiple tv's. I have a cable run and cat5 run to each room and wanted a way to watch hidef movies in each room preferably synced. After much searching I'm coming to the conclusion that this will be hard and expensive no matter which route I want to go. I'm thinking my best route is to build a media converter and pipe that to each room.
I found a couple of HDMI input cards [URL] and [URL] that work in linux. Great with one of those I can get it to a computer signal and even get it on standard coax using a VGA2RCA converter and 1/8 inch to rca for audio hooked up to an old vcr set to channel 3 or 4. And for TV's that support hidef I can hook up computers at each to receive the video over gig ethernet.
So the question becomes what is a good app for sending and what is a good app for receiving. Is gig ethernet fast enough for 1080i? what about 1080p? Comcast has multiple hdtv channels over their coax; so how is it so hard to even encode one channel to an hdtv signal to watch on tv. Is there a way to encode the video to hdtv over the coax like comcast? So I can use the tv itself to watch the hdtv broadcast from my computer over the coax?

So I have a few old dell computers. I want to use them to set up a ubuntu linux server in my basement. Is there a way for me to set up the server over all the pcs so that I can use the processing power of them all together for the server. What would be the best way for me to set a server up with these machines.

Well first I'll give you some background info. I have Ubuntu 10.10 x64 8 gigs of ram AMD 64 X2 Dual Core Processor 5000+ ATI graphics card I just installed Ubuntu on my second HDD yesterday and am using my BIOS to switch between the OSes (basically just staying in Ubuntu in other words. I have had no issues installing Ubuntu what-so-ever.
Heres where my issues come in. Firstly every time I restart my computer it doesn't allow my bluetooth devices (mouse + keyboard. Both made by mircosoft. Dongle is a microsoft product as well) to connect right away. I have to go into the BT settings and click "Make my computer visible" (or something to that effect). After I do this (all on my wired keyboard and mouse) and i hit a button on my keyboard and mouse they are then able to operate my computer. Does anyone know how to fix this problem? Another issue that I am having is that my computer WILL NO LONGER recognize the names nor the demintions of either of my monitors (a visio 42 inch connected via HDMI and a acer 22 inch connected via VGA. both going to an ati graphics card). On top of this my computer will not switch the default monitor from my 42 inch to my 22 inch and this is the larger of the two issues in this section due to the fact that I dont always use my TV -> thats usually when I'm watching movies Does anyone know how to fix this problem?
I am extremely new to Ubuntu and Linux as a whole. I have greatly enjoyed the learning experiences that I have had in the past two days. Also I just prefer Ubuntu to windows. Its sleek its fast and its fun to tinker with . If it would not be a problem please explain the reasoning behind any solutions. And PLEASE feel free to ask any questions, Im here to help you help me! Just kidding. If i can ever return the favor just let me know!

I am gradually getting used to the CLI for Ubuntu. I am used to switching between windows when editing a file, going to the command line to run a cmd, and then back again etc.
I feel severly restricted by the CLI, as it seems I can only do one thing at a time. Surely, there must be a way where I can 'switch between' several command line consoles?
Also, I am using vim, and I sometimes need access the command line. At the moment, I have to quit vim to get to the CLI, and then start vim again. This is not very productive.
How to switch between CLI screens/consoles and also how to switch to the CLI from withinin vim and then back to vim again without having to close vim?
My distro is Ubuntu Lucid Lynx (10.04 LTS)

I am in the process of coverting some video files to motion jpeg (Wii) files with ffmpeg (great program by the way). I have been successful and so the majority of my work is over. My question is simple (I think) but complex to me so... here it goes. Is there a way on one command line to "batch" convert 8 or 9 files together instead of one by one. I just don't know what to put on the command line. I took one UNIX class a long time ago and the terms pipe and such come to mind... but I forget. Any takers? That was I can write what I want the computer to do in the morning and just come back after work and voila...

The music I ripped with Sound Juicer, or ripped with VLC and tagged with EasyTag both have the same tag issues. The tags work great system-wide in Ubuntu, and if I drop the song on a data CD and put it in my Pioneer stereo, the tags work there, too. I can put the song on my Walkman and then copy it to another Ubuntu machine, and the tags work on the second machine, as well.
However, the Walkman lists the song as Unknown Song, Unknown Artist, Unknown Album. Further, if I transport the file into Windows, the Windows system doesn't recognize the tags, either.This begs the question, are there multiple tag formats?

Why I can't use multiple identities!
I have two sets of RSA key files:
I want two different SSH logins to the same server, so I create the following in ~/.ssh/config
Then in my server account on xxx in ~/.ssh/authorized_keys I have:
The idea is to use:
The latter as a transparent gateway to yyy through xxx.
Now this works just fine, but I have to remove either id_rsa or test! Why?
Can I user .ssh/config like this?

It says in the geany documentation that i can specify multiple cursor positions. But after i define a snippet like that - lets say for example:
Code:
for=for ($i = 0; $i < %cursor%; $i++){ %cursor% }
it only takes me to the first cursor point. A second tab results in a regular tab being inserted into the code..

What do people use to run multiple applications in one terminal?
Thinking of turning my GUI into a big terminal with openbox on top and was thinking, where would I find a command-line timer tool?
And if I only had one terminal, how would I switch between applications? A 5 hour timer isn't nice if it locks up the terminal for 5 hours...

I had Ubuntu 9.10 running ok, but I've decided to try Lucid Lynx with Kubuntu and was quite impressed with the quality of KDE. Everything worked out of the box also.Until I tried to login with two other accounts this computer had...With one of the users I get both errors seen on the snapshot. One regarding the network manager (which I think it was given just because it was already started by another user), and the ibus error, which completely locks the user from accessing any other drive or usb disk.For the third user, even if creating it from scratch (not re-using his /home), I get an error:
Code:
kstartupconfig4 does not exist or fails. The error code is 3. Check your installation.
/home is in another partition that's been used since 7.10 I think. I did cancel all /. from

I use Ubuntu 10.04. I switched from KDE4, where it was possible to use Compiz's Wallpaper plugin to have multiple wallpapers, so that each desktop has a different wallpaper. I tried to use this plugin now, and it doesn't work.
I read some interesting facts here:
[URL]
Obviously this info is a little obsolete since it is about Hardy, but it looks like recompiling Nautilus is still required. Can somebody tell me how to do this? Which packages do I need? Where to pull the right code from? Are there any precompiled Nautilus packages for Ubuntu 10.04 supporting Wallpaper plugin? (that would be amazing)
