@Danatela what do you mean "two paths" in your answer here? If you mean you can only install from CD or USB that's wrong, you can also boot the ISO from the hard drive using grub.

Rinzwind

@terdon oh good one!

put it in as an answer and Ill upvote

terdon

@Rinzwind I would but it's tricky. I've never done it with grub2 (I used to do it very often with legacy) so I'd have to check the details.

Avinash Raj

@Rinzwind Mitch already posted an answer about that.

Rinzwind

can you install grub from windows :)

terdon

You can also install over the net. At least you can with Debian so I imagine it'll be possible with Ubuntu as well.

@Rinzwind That might be an issue yes. My method assumes grub is already there.

Danatela

13:22

oops

Rinzwind

yes but the pixie install requires a 2nd Linux system and he does not have it

A: Install Ubuntu from ISO image directly from hard disk of a system running Linux?

I found this looking around on the net. Grub2 is capable of directly booting ISO images for many Linux distros if the entries have been properly defined in the Grub2 configuration files. The ISO image can be placed virtually anywhere on your HDD but for the sake of simplicity, we would place it...

Rinzwind

@terdon not being able to boot from dvd or usb sure sucks _O-

terdon

@AvinashRaj There you go, perfect.

Rinzwind

@AvinashRaj wont work... he only has windows on the system

@terdon nope >:)

terdon

13:25

@Rinzwind I mean there you go for the grub method. Getting grub in the first place is a separate problem :)

Rinzwind

Q: How to change terminal window's title?

@blade19899 Condoleezza Rice

blade19899

Seriously! That Dr. Rice

Rinzwind

she is a FIRM believer of governement being allowed to view ANY data ANYWHERE.

terdon

13:58

@Rinzwind Actually, not sure that was her. Wiretapping was and a lot of the Iraq "war" was but I'm not sure about the water boarding. That was more rumsfield's baby.

Condoleezza Rice

Condoleezza Rice (; born November 14, 1954) is an American political scientist and diplomat. She served as the 66th United States Secretary of State, and was the second person to hold that office in the administration of President George W. Bush. Rice was the first female African-American secretary of state, as well as the second African American secretary of state (after Colin Powell), and the second female secretary of state (after Madeleine Albright). Rice was President Bush's National Security Advisor during his first term, making her the first woman to serve in that position. Befor...

jrg

@blade19899 copy.com

Rinzwind

google drive is cheaper and 100 Gb

blade19899

@Rinzwind 100GB? since when?

Rinzwind

(2 dollars per 100Gb)

jrg

copy is good, so is drive. but drive doesn't support linux for the desktop client.

Rinzwind

copy.com is good too

blade19899

grive desktop

Seth

14:02

@terdon migrated (in case you wanted to answer)

Rinzwind

but what is wrong with a NAS at home with FTP?

does the same thing :P

terdon

@Seth Thanks, I just noticed, that was quick!

blade19899

@Rinzwind House burns down, what then.

Rinzwind

my NAS is at work :=)

terdon

@Rinzwind Work burns down, after the party, what then?

Oli

14:03

@Rinzwind !!! And just $9.99 per TB. That's ridiculous.

Seth

@terdon Trying to get that little blue notification out of my toolbar ;P

terdon

I tend to have one backup on my NAS at home, another at work and a third somewhere online

Rinzwind

then 1/3rd of Holland has no internet _O-

Oli

Shame it would take me about a year to upload a terabyte. Stupid asymmetric lines.

terdon

@Seth I was so tempted to go flag one of your posts, just to bug you but my better nature prevailed.

blade19899

14:04

I keep my backup on my laptop, external HD, and somewhere far away(online)

Seth

@terdon haha

Rinzwind

@Oli that is not bad at all :)

and 1st 15Gb is free too

Seth

@blade19899 add a comment suggesting that. Maybe a link with a workaround too.

Rinzwind

wtheck is this: askubuntu.com/questions/447660/…

Aditya

Anyone know if there are commands called on and off in Linux? I want to create aliases for them... (They are not present in my system presently, but I want to be certain before doing it)...

Seth

14:10

@Rinzwind wat

Aditya

@Rinzwind lol

Rinzwind

@Aditya not that I know :-) so feel free

Oli

@Aditya The command-not-found (or whatever it's called that runs when you try to run something that doesn't exist) can't seem to find either, so I think you're okay immediately.

Rinzwind

if in doubt add a digit to the alias :)

on1 and off1

Aditya

Right then... Let me search how to create aliases

Rinzwind

14:12

@Aditya -search-? :-D

Aditya

@Rinzwind I am a very noob in these matters ;)

Rinzwind

see .bashrc :=)

Avinash Raj

bash_aliases

Rinzwind

# some more ls aliases
#alias ll='ls -l'
#alias la='ls -A'
#alias l='ls -CF'

terdon

@Aditya even if there is such a command, having an alias will not be a problem, the command will be simply ignored in favor of your alias.

Rinzwind

14:13

@Aditya apparently ;-) lol

Avinash Raj

alias clr='clear'

Rinzwind

oh and

# Alias definitions.
# You may want to put all your additions into a separate file like
# ~/.bash_aliases, instead of adding them here directly.
# See /usr/share/doc/bash-doc/examples in the bash-doc package.

Avinash Raj

gedit ~/.bash_aliases

Rinzwind

so kudos @AvinashRaj

Aditya

@terdon That is why I want to be certain... I don't want my aliases to override genuine calls to those commands...

Rinzwind

14:14

@Aditya It is my strong opinion that that would be the fault of the creator of that command. I'd file a bug! >:-D

Avinash Raj

searching the meanig for kudos...

terdon

@Aditya That will never be a problem. If there are any scripts using the actual commands, they will still use the commands. Aliases are not available in scripts unless you use shopt -s aliases and your scripts won't have them. Anyway, system scripts are usually run by root who won't have your aliases in the first place.

Rinzwind

nl.wikipedia.org/wiki/Kudos_%28computerterm%29 ;)

oopps now you need to learn dutch too

Avinash Raj

> praise and honour received for an achievement.

@Rinzwind thanks :-)

Rinzwind

:=D

@terdon you always spoil the fun :-P

Aditya

14:16

@terdon Oh... that solves the problem... But if I am running the script - are aliases available to them (suppose using python's subprocess or os.system())

or using any bash script generally

terdon

@Aditya No. Not unless you specify shopt -s expand_aliases in the bash script.

Rinzwind

hmm why use aliases in scripts? :-P

terdon

1

A: Alias scoping in bash functions

An alternative solution is to paste those commands into a text file instead of a function block. Something like: ## This is needed to make the sourced aliases available ## within the script. shopt -s expand_aliases source /some/environment/setup/script.sh aliasToSetupSomeSoftwareVersion anothe...

I quote the relevant section of the man page there

Aditya

@Rinzwind No... I don't want to use aliases in scripts... Just want to be certain that if there is a command by that name tomorrow, it doesn't break stuff for me

@terdon Thanks... would give it a read

Rinzwind

ah and no that wont break it :)

Aditya

14:22

@Rinzwind or I should say, my aliases doesn't break stuff for that command..

terdon

What do we do with this @mods? Delete? Try to fix? Try to communicate with the OP (seems hopeless)?

@Oli I want to save [this code of yours](http://askubuntu.com/a/445638/114818) using:
cat << EOF | tee ~/Desktop/bash-autocomplete
<all the code given there>
EOF
which went horribly wrong because of bash variables. Any idea how to save that file using command-line? Let me know and I would ask a new question about it. (I am creating a script which I would run once I install 14.04 when it comes out) :)

Infact I don't know what to search for - "how to escape bash variables when piping the output" doesn't give me what I want...

@terdon You might be of help there ^^

terdon

@Aditya What exactly do you want to do? How will your script get the code?

Why would you cat it? Why not just create a file and then have your script cp file.txt ~/Desktop/bash-autocomplete ?

Aditya

@terdon I want the file to be autogenerated, all the code would be written inside the bash script where I have written <all the code given there>

terdon

umm... ookay

Aditya

@terdon I don't want to create multiple files... That bash script would be a swiss army knife

terdon

@Aditya cat <<"EOF" > foo.txt

Nope, scrath that

Aditya

14:55

@terdon oh that works...

terdon

@Aditya Yes, without the quotes, the code is interpreted by bash

Aditya

Is using tee better than output redirection?

terdon

@Aditya Not really, no. Not unless you need to. Using tee will cause the output to appear both on your terminal and in the file

Avinash Raj

how people write answers in math.stackexchange.com ?

grrrrrrrr

terdon

@AvinashRaj ??

Avinash Raj

i tried to provide answer for a question in math.SE.But i can't because of formatting.

it's really tough

terdon

@AvinashRaj Oh, enclose your equation in $blah blah $

It uses MathJAx, basically LaTeX formatting

Aditya

@Avinash try Libreoffice math

terdon

@AvinashRaj Look here: math.stackexchange.com/editing-help

Or just show me what you want to post and I'll make it into LaTeX for you

Avinash Raj

@AvinashRaj Yes... you can build equations... I hope it should give the output which is compatible with mathjax or latex as terdon mention

terdon

Avinash Raj

@terdon it's so easy ^^^. Thanks ...

Venki

Do I need propreitary graphic driver to get a conky working?

terdon

@Venki No, you shouldn't. But it will depend on your situation. What's the issue?

Venki

Yesterday I installed conky manager and got a conky theme pack...Enabled a conky..made it to start on OS startup...rebooted....bricked my OS!! :-( Couldnt even get a tty...and had to reinstall the OS!! So today I am wondering if it was because I didnt get my graphic driver installed...

terdon

@Venki Whoah! No, that shouldn't have anything to do with the driver. Shouldn't have anything to do with conky either. Are you sure you did nothing else?

In any case, if you can't get to the tty, you know it's not a graphics problem.

Venki

Hmmm...Well..Conky manager aint there for 14.04..so I changed the rep sorce of the PPA to 13.10. That caused the issue?

terdon

15:52

@Venki Not yet, no. But, if you then proceeded to install something and that brought in various dependencies and, for example, upgraded something basic like glibc then that would indeed break your system.

Venki

Yeah..probably that was the problem...I tried to install the propreitary graphic driver since the conky wasnt looking so right..then changed my mind in the middle and cancelled it.....

terdon

@Venki Argh...

Never mix versions unless you really know what you're doing. Anyway, just edit the config file manually, I'd be happy to help if you need it.

Venki

So much for wanting a beautiful desktop...!! Ok..So without conky manager, I will get some conky and ask for help..thank for volunteering to help btw!! :-D

terdon

@Venki I like conky and have spent hours tweaking mine :)

The docs are quite good actually, it is not that hard to set up, depending on what you want.

Venki

You mean docks right? Just now installed Cairo from S/w center...!!

Infinity conky...good option?

terdon

16:03

@Venki No, I meant the conky documentation

@Venki What's Infinity conky?

Venki

Oh!! Right.. Look here : gnome-look.org/content/show.php/Infinity+Conky?content=151516

terdon

@Venki Yeah, OK, that one;s complex. Probably using lua scripts. But you should be able to use the .conkyrc, no need for conky-manager

Venki

Hmm..

terdon

@Venki Hang on, I just downloaded it, let me check

Venki

I downloaded it too. Can you tell me how to unzip ? Sorry for a silly question!!

My comment is right?

Hello, everybody.

Venki

@terdon In the Readme file it says me to adjust things according to res in .lua .. I dont know what to do with it.. The .conkyrc is already according to my resolution it seems(my res is 1366x768, you may already be knowing!!)..

terdon

@Venki There are some other issues with placing things in the right path. Hang on, trying now

Venki

I have a question.

Who can help me?

Just drop your question please

xiaodongjie

@hakermania Don't you help me? Then why you answer me as like that?

@hakermania Do you know about my question?

@hakermania Why don't tell me?

terdon

@Venki actually it works fine, it just complains. I am used to my conly appearing on my left hand monitor and this appears on the right so I hadn't noticed :)

Simply adapting the paths used in the conkyrc was enough

Basically, follow the readme.

Venki

Right .. what about the .lua file ... no need to edit?

@terdon

terdon

@Venki no, just point the conkyrc to wherever you save the scripts

Venki

16:40

Ok. Fine. Will run it and get back..

Oh!! it looks distorted!! will paste a screenshot...

@terdon

Rinzwind

boo

terdon

16:55

@Venki Looks like a resolution issue

The png is probably being stretched too much

Venki

So if I change the image to something else it will work fine?

terdon

@Venki Ah, no! Hang on, that's the text that's distorted. OK, change the font or disable anti-aliasing in the conkyrc file. You probably don't have the default font installed

Venki

Ok will try

Venki

17:11

@terdon How to do i disable anti aliasing? Probably its not the problem with the font. Because even after changing it the problem persists...

@Venki Change use_xft yes to use_xft no in the .conkyrc. Not sure if that's your issue though, it works perfectly here

Mayukh Nair

Get well soon @Rinzwind

Alright

So, any awesome trick possible with Ubuntu? Something that's rarely known?

terdon

@MayukhNair I ask you again. Did you try searching? I just spend about one minute and found that you need to set GRUB_HIDDEN_TIMEOUT to 0

Venki

@terdon tried anti aliasing and tried chaniging fonts. Not working right.. Begining suspect that I need the propreitary graphic driver....

terdon

17:25

@Venki I really doubt that. It shouldn't be necessary, what DE are you using? Is this unity?

Venki

Yes

Mayukh Nair

I did search. I learned my lesson.

terdon

Well, try setting GRUB_HIDDEN_TIMEOUT to 0.

A: Hide Grub2 Boot Menu?

If you have more than one operating system, it can be challenging to hide the grub2 menu. The easy way to accomplish it is: First, download and install grub-customizer from https://launchpad.net/~danielrichter2007/+archive/grub-customizer OR just do these steps in a terminal: * sudo add-apt-rep...

Mayukh Nair

Alright. I hope Ubuntu boots after that, cause I dunno whether it'll completely disable any access.

^That is what I read.

Didn't help at all.

I'll try hidden timeout to zero and get back.

terdon

@MayukhNair hmm, hang on, you have multiple operating systems installed right?

See the last post here: ubuntuforums.org/showthread.php?t=1302684

Venki

17:32

@terdon I am using unity

terdon

@Venki Yes, there are some issues with unity and conky, I don't use unity so that might be the difference. I'll try on a VM

Venki

Ok. So you know any lightweight(yet good looking) conky? Maybe that might work for me...

terdon

@Venki You don't need lightweight, the issue is font display so that will be the same for all.

Venki

Ohh!!! Hmm... Disappointed! :-(

Well...Can I get fonts for conky somewhere?

@terdon Sorry for pinging you a lot!!

terdon

@Venki no problem

I've broken my VM at the moment so I can't test on unity but have you tried simply using a different font?

Mayukh Nair

17:39

@terdon Timeout zero failed worse than the Super Mario Bros. movie. :/

terdon

@MayukhNair Yeah, did you see my last message? That's because you have multiple OSs installed (which you should add to your question by the way)

Mayukh Nair

ALright, editing.

Venki

I have tried with differnet font.. With "Ubuntu" and "Ubuntu Medium" fonts...

Mayukh Nair

THat's what I am reading.

terdon

@Venki in fact, looking at your screenshot, the problem is that antialiasing is not enabled, not the other way around.

Did you make any other changes to the .conkyrc?

Venki

17:41

Well, it was yes after use_xft .... I didnt make any other changes..

terdon

OK

I wonder if Ubuntu just needs some package for the xft to work.

Venki

Well.. I got conky all, curl, anything else?

@terdon

terdon

No idea. Just wondering :)

Venki

Hmm.. So will try some other conky and get back to you some other time... Its late here! 11:22 pm Gonna sleep. Bye and thanks a whole lot!! +1,000,000,000,000..... for you!!

@terdon

terdon

@Venki Sorry we couldn't figure it out. I'll have a go when I fix the VM

Venki

No problem. Time is infinite. We will come back some other time. Bye again!! :-D
