Lately I have been reading up on vm.swappiness. What range would you recommend I look at, my system is:
- AMD 64 X2 6000
- 8 GB on-board memory
- plenty of HD space
Usually I have only one or two programs open at a time....
When I boot my computer I get this message: Warning Pc video resolution is out of range Change setting to recommended resolution 1280x1024 @60mh So I hit ctrl alt f1 I typed in Sudo dpkg-reconfigure xserver-xorg Nothing happens. It's been very frustrating because with everything that I've looked up it says that it's suppose to guide me through something. I desperately need my computer for school.

View 6 Replies View RelatedI want to plot a set of data in only one plot.The problem is that some points of the data should be better plotted in a linear scale (lets say 0 to 100,000) but there are other data points that, exceding the value 100,000, would be better plotted in a logarithmic scale, as they goes in the range 100,000 to 500,000,000. Let's say the data is:
Code:
X Y
0 100
10000 80
20000 75
[code]....
Is there a way to plot all these points in the same plot in only one X-axis showing two different ranges in that axis: linear: 0-100,000 logarithmic: 100,000 - 1,000,000,000?The axis would be read, for example, as:
Code:
|-----|-----|-----|-----|-----|-----|-----|-----|-----|
0 20k 40k 60k 80k 100k 1M 10M 100M 1G
(The abbreviations k-M-G are not the important point. Just shown for clarity)
I want to build a bash script, which can ping a range IP adresses which will be filled in by the admin. If there is no IP-adress filled in, then the script must ping the subnet where the system is logged on. So if my ip is 192.168.1.6, then the script must ping from 192.168.1.1 till 192.168.1.255 Or else, if there is given a beginning and ending ip it must ping that!
The first part of the bash script is to ping a given range (see below). But there is one problem, how can I tell the script to ping from $begin till $end, [..] is of course wrong! But what must be filled in there???
echo "Enter beginning IP-adres:"
read begin
echo "Enter ending IP-adres:"
read end
ping -c 1 $begin [..] $end
The second part is to find my own ip and ping the whole range.. How to do that? I only can find my own IP, but I cant ping the whole range,, how to do that?
#!/bin/bash
ifconfig | grep 'inet addr:' | grep -v '127.0.0.1' |
cut -d: -f2 | awk '{ print $1 }'
So I'm getting a new laptop soon, and it ships with Windows 7 64-bit. So I assume I have to use 10.04 64-bit. I noticed that the download page says "not recommended for daily use". I was wondering why this is, and if there were any things I need to look out for when using Ubuntu and 64-bit. I read the older FAQ thread in the closed 64-bit forum, but I wanted to make sure I got more recent information.
View 5 Replies View RelatedI've been having some issues with the speed of firefox recently (on a netbook) and have been trying out other browsers such as chrome and midori. Currently I'm using xmarks, which fits my needs nicely however, I'm looking for an alternative that gives similar functionality and would allow me to access my bookmarks from several different computers (using both midori and chrome browsers).
xmarks has a development version for chrome, which is not working at the moment, and I cannot find any plans for xmarks in midori.

View 8 Replies View RelatedI have Ubuntu 10.10 but I can only use Windows 7 now (I hate it). Here's why: when I go to the boot screen and I am given the choice of using Windows 7 or Ubuntu and I select Ubuntu, the screen goes black and says:
error: unknown command 'loadfont' error: file not found
Then I have to reset my laptop and use Windows 7. This happened when I was using Ubuntu like I usually did and I downloaded recommended updates from Ubuntu. I downloaded them and I was asked to reset my laptop for it to be effective. I did and when the boot screen came up it said what it says above. I can't even get to the login screen. I've been searching everywhere for an answer.
I'm using 10.10. The FSpot and Shotwell programs that came with 10.10 don't seem to have any good controls for adjusting slide show display of photos. Could anyone recommend a good photo slide show display program that allows one to adjust pan, display time, smooth transitions, etc.

When I finally purchase a new laptop I will be running the latest Ubuntu on it (probaly 11.04 0r 11.10), I will be using the laptop for downloading and burning alot of movies to DVD's, watching movies (from DVD's and my portable hard drive), using office, surfing the web, using email and live chat as well as other basic tasks (updating and downloading software). I would really like to know what CPU and how much ram is recommended for a laptop running these processes regularly.

View 9 Replies View RelatedI have a server setup with all my web development stuff in /var/www and in several sub-folders within that. (each project having it's own folder)It works great with one FTP account. But recently I've been getting help on a projects from a buddy of mine that freelances, and have made him an FTP user account as well. All is fine, except for when he tries to edit a file and gets a permissions error.
Here's the issue, I don't want us to have the same FTP login, but all the files are currently owned by my user name. So, when he logs in to edit a file, he can't because I'm the owner, and the files are set to 744. Will I cause any harm by adding both users to the same group (www-data) and chmod'ing the files to 775 so that we can both access and modify the files?
I'm fed up with Gentoo and would like to migrate to Ubuntu. I just installed 10.04 Beta, but I'm wondering if I should continue configuring my system. Is it possible/easy/painless to upgrade to the release version when it comes out? Or should I stop investing any work into the beta right now and wait for the release?
View 3 Replies View RelatedI just installed Ubuntu 10.04 Server the other day, which gives me access to a command line only, to start out with. I'm hoping someone would be able to recommend a guide (online or a book, either way) for absolutely clueless beginners, so that I can learn to competently get around from the command line.
This would include information like:
Navigating the file system.
Editing text document.
Installing drivers.
Mounting data sources.
Installing and configuring packages.
and eventually installing a desktop environment.
I was wondering: Is there a way to upgrade to a new Ubuntu version without completely reinstalling the system and to use the recommended apps and settings of the new version?
Reason I ask is that almost every time I upgraded to a new version by using the update-manager and than later installed that new Ubuntu version on another computer from scratch, I noticed that there are some differences. For example let's say the new version promoted a new UI design or some default apps have been replaced. These changes have not been applied to the upgraded version.
I decided to create a file server for my family. I have set up a RAID 6 (4 disk) array. My thoughts were to back up the array to a hard drive monthly. Store the drive in a WiebeTech Drivebox, off site, in a "fire proof" box. (The kind for papers sold at Staples or Office Depot. After a year, I would have 12 back-ups. I would then overwrite the previous hard drive. (i.e. HDD from March 2011 would be overwritten on March 2012.)
Additionally, I was wondering if there was recommended maintenance to verify the array is working properly. Right now, I am moving data to the array so quickly that I am backing up every few days between three hard drives. (Back-up #4 was written to Drive #1 after Drive #1 was reformatted.) I am aware that I could use rsync. (Which I currently use for backing up my portable USB HDD to the RAID array.)
What is the recommended system specs in order to be able to run Unity with no problems?

I am running a very stable F13 on my little box and I was thinking to upgrade from F13 directly to F15 using the preupgrade-cli tool. Is this recommended, or should I go to F14 first? I would like to skip that step:
The F13 is my home server with a lot of services:
- IMAP (dovecot)
- Postfix
- Postgresql
- apache (tons of php)
- vmware workstation 7.1.4
- dhcpd
- named
- samba
- squid
I am worried that the upgrade will break something. I spent a lot of time setting these things up.
