having problems getting a wifi card to work

I could see the wlan0 device, but it didn't seem to pick up an ip address. This seemed to fix things:

sudo dhclient seemed to fix

WPA and wireless in Ubuntu.

This problem seems to be, at least in some cases, still difficult.

This is one account, from 6.06 ubuntu.

For some machines, things seem much easier in ubuntu 7.04.

Judging from the comments in the link below, the results seem to depend upon the hardware you use, which is not completely surprising.

For one user, "ITS FAR from easy" to get wpa to work. Which make me feel better, given how much trouble I am having getting it to work on a few machines.

Adding fonts in Ubuntu

The fonts that Ubuntu ships with are ok, but limited. It is a good idea, to use the package manager to install msttcorefonts, which makes sure you have the most common fonts, including these:

• Andale Mono
• Arial Black
• Arial (Bold, Italic, Bold Italic)
• Comic Sans MS (Bold)
• Courier New (Bold, Italic, Bold Italic)
• Georgia (Bold, Italic, Bold Italic)
• Impact
• Times New Roman (Bold, Italic, Bold Italic)
• Trebuchet (Bold, Italic, Bold Italic)
• Verdana (Bold, Italic, Bold Italic)
• Webdings

Warren Guy has some detailed instructions on what else you might consider doing, and so too does the Ubuntu Blog.

Using something like the Synaptic package manager, you can find an impressive number of new fonts. But you can also manually add true type fonts. .... (I'm not finished with this reminder yet)

sudo fc-cache -f -v

Changing settings for a video card in ubuntu

A helpful command to remember is, from the shell: dpkg-reconfigure xserver-xorg. I used this today to fix this problem. Ubuntu would not give me the choice of a higher resolution for a new monitor I used. I ran this command, using mostly default answers, and then when it asked about the available resolutions, I checked the ones I needed.

Earlier, on a different machine, I needed to install drivers for a new ATI Radeon 9550, and this worked.

sudo apt-get update
sudo apt-get install linux-restricted-modules-$(uname -r) #Okay if it is already installed
sudo apt-get install xorg-driver-fglrx
sudo depmod -a
sudo aticonfig --initial
sudo aticonfig --overlay-type=Xv

I did not try this interesting page:
