Ubuntu Installation :: Wanting To Make More Permanent Switch Via External HD?
Jun 10, 2010
The idea is that I got to grips with Linux a couple of times in the past; most recently in a Radio Astronomy class (where we had to use openSUSE and terminals 24/7). I loved it so much that I fired up Wubi on my laptop and I am having a play.
Then I loved it even more.
So here's the plan:
Find Windows (Vista) CD *sigh*
Get 500 GB external Hard Drive
Backup files to HD (60 GB max)
Reformat Laptop & Reinstall Windows
====
To my understanding, this gives me a blank slate with a lot of room to play with because of the external HD. If this is not possible/too risky etc. then what are the best alternatives?
The plan is to make my primary OS Ubuntu. The way I figured, to keep things simple, is to keep the laptop's HD with Windows as 'normal'. I would thus install Ubuntu to the external HD, and put my files etc. on that.
Now, is that possible for a clean installation? Ideally, it would be fantastic if the boot can be configured so it would boot Ubuntu if the HD is connected, and Windows if not.

Am quite new to Ubuntu (10.04) and have recently reinstalled XP. I want to make an image of my windows partition to save time and effort when wanting to restore this. I read the Ubuntu documentation on Drive Imaging [URL]..community/DriveImaging and am wondering if I've done things ok?
I've booted using the Live CD. Windows is on sda1 and is a 50GB partition. I have a hidden ntfs partition on the same hard drive at sda9 of 10GB. The first time I tried this I got an error regarding my output file saying "Not a directory". I'm assuming that was because I hadn't mounted sda9. It also reported an error saying permission denied on sda1. I then mounted sda9
Code:
sudo mount /dev/sda9 /mnt
I then changed to root as I thought not being in that was why I was getting the permissions error.
Code:
sudo -s
I've then done the following;
Code:
dd if=/dev/sda1 bs=1024 | gzip > /mnt/sda1.bin.gz
The terminal window is just showing a flashing cursor in the bottom left corner under the above command line input. Is the fact that my mount partition being smaller than my windows partition going to cause a problem or will gzip solve that? My Windows install occupies about 7.5GB of the 50GB partion.
I'm not sure if dd is just taking a long time to complete the task???

I'm running Ubuntu 10.04 and I've been looking to customize what's given as my command prompt, and I learned how to do this by entering PS1="desired text" which is remarkably straight forward.
I'm a little stuck on how to make this permanent though. If you just type in that command, then when you close that terminal session and open a new one, it resets to the old/default prompt. I read the tutorial at:
http://www.cyberciti.biz/tips/howto-...up-prompt.html
and it referred to editing the .bashrc file in ubuntu. I found the bash.bashrc file in /etc/ and edited the line that said PS1=, however it didn't change my command prompt. I searched for other files relating to bash and in clear instances that PS1= was given, I changed it to see if the command prompt would change. This has been to no avail so far though.
Does anyone know which file needs to be edited/what needs to be done in order to make a customization of the command prompt permanent?

In this link, the last poster describes a way to disable tap click which I find VERY useful, but the thing is, after I reboot it goes away. Is there anyway to make this command permanent?

I use Ubuntu 10.04 and after installing the driver for my onboard video card, I can no long boot into Ubuntu. I'm thinking that if I was somehow able to remove it, this might fix the problem. Is there a way to do this, possibly from the boot cd?

Since the 10.10 upgrade my mouse clicks on my laptop have been behaving rather oddly. Sometimes it randomly does a middle click when i'm doing a left click, which is really annoying because it means that sometimes tabs close or my text gets random bits of text appearing in it. I've found that running this command "synclient tapbutton2=2 tapbutton3=0 rtcornerbutton=0 rbcornerbutton=0 clickfinger3=0" fixes it, but only temporarily, sometimes it only lasts like 10 minutes or so, other times it lasts till reboot. So, is there anyway to make these changes permanent?

I installed 11.3 on an eee pc 901 with the ldxe desktop. everything seems to work fine and out-of-box.
But when do some configuration changes on the touchpad using the gsynaptics-gui, the changes only last until the next reboot of the computer.
How can I make them permanent?

i has setup a persistent DNS cache to improve my web-browsing. it works wonders and with my ICC built firefox my web-browsing is laser-fast, pretty much like using internet explorer in windows! however, everytime i reboot, my modifications to /etc/resolv.conf have been replaced... 1st. the file must contain:
# Generated by NetworkManager (obviously modified by this)
nameserver 127.0.0.1 <----this is lost on reboot, and is needed to make it all work
nameserver 209.226.175.223
nameserver 198.235.216.134
i have tried to add this to - System/administration/network, but it doesn't seem to fix the problem. 2nd. my next problem is that when fedora 12 starts up,i need it to start "dnsmasq".i have tried to add it as a startup application, but it doesn't start automatically.so i end up having to start it manually everytime:
sudo /etc/init.d/dnsmasq start
it is annoying, but so far i just deal with it, because my browsing is that much faster! i am planning to post a tutorial for those interested in faster web-browsing in linux, but until i can make the changes perminent there isn't much point.
PS: i have tried to write a shell script to do this and every which way i try it fails

I have just booted to Puppy (for the first time in my life) on a 6 y/o amd type with a 40Gb HD, Ram: 512.I would like to make a permanent install of puppy onto the HD, I have read various pieces on how to install, defraging, repartitioning, differing file systems. However, i am a bit lost. The computer will be used for e-mail, web browsing, and watching the odd film (films installed on the drive) - I am unsure as to the best combination of file types and partition in order to keep puppy happy and keep some compatibility with the world outside of linux.
For instance, could i have a small partition with the puppy install and setting, and the rest on a format that would be compatible with windows/mac/linux? If so, how do I do this, pls bare in mind that my windows install is running but incomplete. I have the feeling this will be a really simple problem for someone to help me with,

just can't find the answer for this one (after Google and these forums) So I want to configure my Synaptics touchpad in this fashion:
Code:
synclient RTCornerButton=8 RBCornerButton=10 LTCornerButton=11 LBCornerButton=12 FastTaps=1 This line of code does what it's intended of it. However, the changes made don't really stick after a system reboot.I'll explain:
So, the "FastTaps" part works flawlessly (as intended). However, the corners bit doesn't work after system reboot!...and weird enough, if I set up a start up script with that bit of code on it it'll only remap the last two corners (LT and LB), because RT and RB always get automatically set to "2" and "3". It's obvious then that those corners are getting remaped somewhere I haven't found yet. I've already tried ppa:yurivkhan/ppa and adding new options to "usr/lib/X11/xorg.conf.d/10-synaptics.conf" to no avail either. how to make the remap of touchpad corners permanent? P.S. - I'm using Ubuntu 10.04 LTS with Macbuntu.

I would like to make group changes on serial ports permanent. I can become root and use chgrp:
chgrp uucp /dev/ttyaa00
but it only lasts until reboot. I think I need to add this line to a startup file but not sure where. I want this to work in run level 3 and 5 (at least). I have a digi portserver and their realport software. The ports are /dev/ttyaa00 through /dev/ttyaa07 and are in group root on startup. I want them in uucp so any user in uucp can use them. This is for F10.

I recently compile Kernel 2.6.34 (to fix the AMD PowerNow issue with 1055T processor, and it worked!) However, the device
/dev/shm
starts up at boot as Read-Only.
Google Chrome requires this device to be user-writable, or it won't start up. Presumably, the stock kernels (and all that are updated) have it set to User-Write. I have not noticed any other ill effects with the permission being read-only. If I do:
sudo chmod a+w /dev/shm
Everything will work from there, but each time I reboot, I have to do that. How do I make that permission-change permanent?

I set up a squid transparent proxy and I have a problem with an iptable rules. I have a rule to redirect all request to port 80 to go on port 3128. To do so, I'm using this iptables command :
Code:
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128
This command is working like a charm. The only problem is, for some unknown reasons, this rule will be dropped at some point. I did not manage to identify what is causing this to happen. It occurs during night, but I have nothing about that in my log files. messages / firewall / ...) The only way I managed to reproduce this 'dropping' is this one: I type the command like as root. The command is effective and working fine. I open yast, I go to the firewall module, the I do a simple "save changes and restart firewall" (without changing anything). As soon as this process is finished, the iptables rule is gone.
-How can I make this rule permanent ?
-Is there a place where I can launch a script executing this rule, after the yast firewall module is 'touched' or something ?

I have a generic monitor which has problems with many Linux distros. We can boos Sugar on a Stick v2 by pressing <tab> at the Sugar splash screen and adding the boot parameter "nomodeset". I'm handy enough to do this, but my wife, well, not so much. So is there a way to make that boot parameter permanent?

Esteemed (K/X)Ubuntu'ers, I need some help. I had a Samsung HDD (Internal) that crashed, was a fault of the store that sold it to me and they went bankrupt. I thought I buy an external HDD (Western Digital Elements 1.5TB) and boot Kubuntu from there, so I still use the computer till I buy a super nice one after USB 3.0 hit the streets.
The problem I keep having by booting of the external HDD is that GRUB keeps saying Code: error: bad filename how to install Kubuntu on a external HDD and make it boot correctly?

I'm trying to setup my media streaming server, and everytying is going quite well, but there's one thing I don't understand. Can you have ubuntu automatically pick up and mount your external USB drive when you switch it on? I don't like leaving the hard drive running, and I only need to have it on when I want to stream something, but it seems to lose the mount when I switch it off and on again. Anyway to make it automatically detect that it's on and mount it back onto my mount point?

i have auto login and a ultra simple admin password, so it wasn't hard for them to mess with stuff...so when i came home i see that they had gone into terminal and added something to my system. i cant recall what it was because as soon as i saw in the history "warning this will make permanent changes to your system do you want to proceed" and the falling yes i got up and started bitching out my roommate and when i was gone someone had closed terminal. i was wondering is there is a way to search my recent terminal activity to see what was done so i can then find out if i can fix what was done?. or is there another option i should look into?

My laptops screen has recently gained an annoying blue tint, which i do not have the expertise (or money to pay somebody) to fix, so i am using my TV as an external monitor. So what i am proposing to do is purely use the External and leave the laptop monitor off. I am dual-booting Windows XP and Ubuntu 10.04 Devel, In XP it was a simple case of right clicking the Intel Graphics Media Accelorator and choosing the External Monitor option, this then allowed me to set my resolution to 1280x960 and i was happy. (even bigger desktop than before actually)
I cannot seem to find this option in Ubuntu, going through System -> Prefrences -> Monitor gives me the option to mirror the screens, but that leaves me with an incredibly low resolution, choosing to not mirror the screens allows me to set the resolution to 1280x960, but the LCD screen still acts as my main. Is there any way I can set it to recognise the TV as the main, and switch off the LCD like I did in Windows?
