View 6 Replies View RelatedI am running Linux from a DVD, not installed. I am not good with installing software, but since the DVD cannot be corrupted, I am content to operate this way. Lately, I have been having problems that previously did not occur. When I try to click on the checkbox to get rid of emails, it doesn't register in most cases, or when it does, I am clicking multiple times so it registers twice, meaning it is unchecked again. Even more frustrating is some issues that are affecting my ability to update my business. I am trying to modify spreadsheets (text not calculations).
Whenever I try to click & drag to select something to change, it keeps jumping around to select only some of what I want, something else or some combination of the 2. When I try to copy and paste several fields from 1 column to another, everything from the several fields in the source column ends up together in the last field in the target column. I am also trying to download some images from a website. There is a single column of links to the images. I have to click on the link to get to the image in order to copy it, then back out to continue looking for more links to do the same.
My computer keeps jumping back 2 steps, then forward 2 steps, and sometimes I lose my place in that list. I could deal with it if it were a small number of links, but this is a list of probably close to 20,000 links. Again, i am operating off of a live DVD so this should not be corruptible, but this has just started happening, and has been an issue the last several sessions.
I know that ImageMagick's convert program can be used as follows to convert a collection of images -- say, in PNG format -- to a PDF file:
convert *png output.pdf
The problem with this is that each image is then stretched to fit on one page, whereas I would like to keep the original dimensions of the images and put as many as possible on one page in the PDF file before moving on to another page.
I am just spent half an hour hunting for a thing that should be totally available already:USB install images of Ubuntu, knoppix and all the others.And, the only good way are so far complicated tutorials where you extract the stuff from an CD image. Why??Hasn't everybody notices that CDs/DVDs are vanishing big time? That more and more systems don't have the readers anymore? Instead of following a 10 point instruction list, it would be nice to just be able to download a Ubuntu 8.10 or whatever USB image and be able to beam that DIRECTLY to a USB stick with a dd command.
Or am a missing something here? Does this exist?It should by no means be mariginal, considering how important USB stick in specific and flash memory in general have become.
I have a very dumb questions regarding run-parts utility. I've created few shell scripts, chmod them to be executable, placed them into one particular directory and tried to run them using run-parts utility like this
run-parts dir_name However it doesn't seem to be working or I might just be missing out something. I have even tried different options like --test or --list - NONE of them produced any output. If I run each of the script manually they all work just fine. Is this is a known bug or somethng ?? or am I really missing out something...how are the /etc/crontab entries then being executed when the run-parts doesn't seem to be working on such a simple case ? ps: I noticed one interesting thing though...when I run run-parts like this: run-parts --list --regex 'some_regexp_patern' dir_name -> the output actually produces a list of the files whose file names match the given regexp pattern .
Suppose that I have this text :
1 abc
2 def
3 ghi
4 klm
Now I want to copy(yank) only the parts:
ab from line one and hi from line three at the same time
So how can this be done with vim? I know how to copy one line and one part of a line. What I want to do is to copy two parts from 2 different lines at the same time and paste them as they are some where else in the file.
I am completely new to Ubuntu so please make your answers really simple ! I want to set up a mail server for a home network and have been suggested I use the Ubuntu solutions. I am fairly proficient with Windows programs and even construct databases but I am a complete novice when it comes to command line instructions. Yes, I know I have been spoon fed!
I have been told that it is possible to install Server programs from the Desktop version and that they provide a GUI in most cases. Is that so? I have the desktop version running and up to date but I am unsure what to do next. Starting the Server ISO CD from Desktop seemed logical but when I did I was not sure if it was correct and backed out. I have also read a thread on this forum that suggests the use of Zimbra as a Mail Server, it sounded like my kind of solution so I think I would like to try that.
One last factor. I have an existing P2P network (2 Vista, 1 Mac Book and this Ub' desktop/server) running already which uses the Router for DNS. I suspect I am going to have to do things in a certain order if I am not going to go backwards and ruin the families email and surfing!
parts of my screen keep freezing and locking in place so that nothing new can be seen in that section, it happens when i click a menu or close a window, the part that freezes only goes away after i log out and then back in

For example:
Original file name: filename1.abc.xyz.some.other.stuff

Without a long tale; suffice it to say I had to do a clean install when I upgraded to 10.10 version. I have messed up evolution e-mail and my document viewer settings. I have what I need as far as by ISP settings but the Evolution folders; well that is messed up. What I am looking for if it is out there would be links {read directions to} tutorials for Evolution and Gnome. Everything comes into the unmatched folder on evolution so I think I need to find where to read up on 'Folder rules and permissions'. The document view just is not working so I know I need to read up on that; I think it is part of Gnome but I'm not positive.

View 8 Replies View RelatedIn Thunderbird, when composing a reply to an email that you have quoted, is there a way to cut only part of the quoted material? A typical situation is that you have exchanged a series of emails with someone and your reply has all the old emails from your and the otherperson quoted in it. The quotes are nested inside each other. Often I'd like to chop off all the very old messages and just leave the last few. But the Thunderbird editor seems to make it an all-or-nothing proposition. I can cut the whole quote, but can't highlight a few nested parts and cut them.

View 4 Replies View RelatedOn my c shell, I use the alias p ls -lt; pwd to speed up things while switching directories and getting their listings.Things could be much easier if I could somehow divide the space I have on my console in two parts such that the prompt is in the lower part and the top part always shows the listing of the current directory (the directory which I am using in the second part).The upper part needs to be dynamic in the sense that whenever I switch directories using the prompt in the lower part, It should give the listing of the current directory in the upper half.

I have a registered domain (let say domain.com ) with a web server (www.domain.com) hosted somewhere online.
I handle the mail part in my private network, by giving the MX my WAN IP (111.222.333.444 )and NAT routing mail stuff to the mail server (10.7.167.3) It works fine.
I will have to handle sub-domains (foo.domain.com & bar.domain.com) and also another domain (anotherdomain.com) in my network. In that case NAT routing isn't going to work ...
What do I need to set this up ? I guess I need a DNS server in my network but I'm not sure if there won't be a conflict somewhere with the Registrar's DNS and mine. Or do I have to take the whole DNS of my domain on this new server and make it half public/half private in some way ?
