laptop screen randomly dims in ubuntu

There is another place to set gnome power manager options:

Start Gconf-editor:
Alt-F2 > type gconf-editor> run

Select apps menu > gnome-power-manager
There are some options to try:
- dim-on-idle
- backlight menu > idle-...

Now, notebooks have very specific hardware that have specific issues. Some options in some computer still don't work

ORACLE CONFIGURATION IN UBUNTU 10.04

Q. How do I install Oracle Database XE Server on my Ubuntu Linux desktop system?
A. An Oracle database consists of a collection of data managed by an Oracle database management system. You can download Oracle Database XE server for Debian, Mandriva, Novell, Red Hat and Ubuntu Linux distributions. First you need to get databases up and running in order to use Oracle. The Oracle database has had a reputation among new Linux users as difficult to install on Linux systems. Now Oracle Corporation has packaged recent versions for several popular Linux distributions in an attempt to minimize installation challenges beyond the level of technical expertise required to install a database server.

Make sure you have enough disk space and memory

If you have less than 1GB memory run the following commands to create swap space:
$ sudo dd if=/dev/zero of=/swpfs1 bs=1M count=1000
$ sudo mkswap /swpfs1
$ sudo swapon /swpfs1

Debian / Ubuntu Oracle installation

First modify /etc/apt/sources.list file:
$ sudo vi /etc/apt/sources.list
Append following line:
deb http://oss.oracle.com/debian unstable main non-free
Save and close the file. Next import GPG key:
$ wget http://oss.oracle.com/el4/RPM-GPG-KEY-oracle -O- | sudo apt-key add -
Update package database:
$ sudo apt-get update
Finally install Oracle:
$ sudo apt-get install oracle-xe

PALM PRE TREO phone

UBUNTU 9.10 is the best version i have ever seen

Thanks for the open source creator for creating such a flexible options and many ways to personalize our selves. This entire aggrandize is as i started using UBUNTU 9.10 which made everything easy for me and all i require is only connecting it once to the wired internet for upgrading its firmware for my lappy i don't know how it works for other manufacturers( i am on dell).

But i am sad in one angle as i now don't have much work to try on it or test on it now it became a cake walk for me using ubuntu 9.10 anyways for all the future endeavors i wish UBUNTU guys a big success and happy new year

UBUNTU AND DELL INSPIRON 1525 f**k man they are born rivals i guess

Hi guys, I was now trying to mess my laptop with all the possible ways. as i am more towards open source coz they give you the freedom ur looking for and which i want. And as a noob i prefer using ubuntu as my standard linux operating system which i personally suggest you all to use if you prefer playing with OS. and in this installation i got another problem which is my Dell 1395 wireless card. Linux specially ubuntu is still not supporting this Dell Wireless card. And here in my Univ i will be desparately looking for wi- fi spots than lan. so i thought to struggle some how and get it connected and i suceeded atlast.

Now i am giving the steps of making your wireless card enabled for networking.

first the process is we use ndiswrapper to use our windows version of devise driver software and work it with ubuntu


After trying many different approaches suggested all over the web, and gathering clues in many Ubuntu forum posts, I finally worked out this solution:

1. blacklist bcm43xx

echo 'blacklist bcm43xx' | sudo tee -a /etc/modprobe.d/blacklist

2. install ndiswrapper and related files

sudo apt-get install ndiswrapper-common ndisgtk

(this should also pull in the 'utils' package)
when I was all said and done, I had
ndiswrapper 1.45
ndiswrapper-utils 1.9
ndisgtk (you don't really need this, and my instructions don't make use of it)

3. download and extract http://ftp.us.dell.com/network/R174291.exe

this is a ridiculous bit of bloat, but the most complete INF for 43xx devices

4. go into folder DRIVER_US inside the result of what you did above

5. use ndiswrapper to install bcmwl5.inf

sudo ndiswrapper -i bcmwl5.inf
sudo ndiswrapper -m (this one will give you a bunch of warnings - ignore)
sudo ndiswrapper -ma
sudo ndiswrapper -mi

(I don't honestly know if the last three steps are necessary, but can't hurt)

6. reboot your machine

Atlast back

Hi guys i am back after a long time. Now i am in US and doing my thesis and struggling a bit for my living and things. Anyways how are you guys doing?
