Colorfull gnome terminal

Most popular distro Ubuntu in current version 10.04 comes with gnome terminal as default. But colors have gone. Gnome terminal uses colors for ls listing. But to less.
Edit your .bashrc

"gedit ~/.bashrc"

Allow force_color_prompt=yes, probably just remove opening #

"force_color_prompt=yes"

I altered the color schema as well. I like white on black background.

"Edit -> Profile settings -> Colors" - choose your desired built-in scheme or make your own

Ubuntu 9.04 jaunty, kernel 2.6.30 and Broadcomm wireless drivers

Oh long story ... I upgraded ubuntu jaunty to kernel 2.6.30 because I had troubles with freezing my Intel GMA 945 internal graphics. Fine and everything went OK. But...

My wireless network was gone.

Here is solution:
* On http://www.broadcom.com/support/802.11/linux_sta.php download driver (32, 64b according to your pc)
* carefully read http://www.broadcom.com/docs/linux_sta/README.txt
* do step included in this readme

Wait, wait, wait - about 20 seconds, and my wicd recognized many wireless networks including mine :)

For autoloading of this module you need:
*

sudo mkdir /lib/modules/2.6.30-xxx/broadcomm-wlan/

*

sudo mv wl.ko /lib/modules/2.6.30-xxx/broadcomm-wlan/

* refresh modules

sudo /sbin/depmod -ae

*

sudo gedit /etc/modules

* add new line with "wl"
