Did a fresh install + updates of Kubuntu 8.10 on a customer’s laptop and had no wireless even though it’s an Atheros chipset.

Hardware:

• Laptop: Acer Aspire 4520
• Wireless Card: Atheros AR242x Communications Inc. 802.11abg

lspci | grep "Atheros"
07:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)

Resolution:

sudo apt-get install linux-backports-modules-intrepid-generic

After above install completes, reboot, then open up the Hardware Drivers manager (jockey-gtk or jockey-kde) and disable “Support for Atheros 802.11 wireless LAN cards” and make sure that “Support for 5xxx series of Atheros 802.11 wireless LAN cards” is enabled then reboot. You may need to reboot to see both drivers in the Hardware Drivers manager.

This is at least a temporary fix, you’ll end up with the ath5k drivers- hopefully a stable universal method for Atheros card support will become available soon.

So even Windows lets you disable the Recent Documents feature, but for some reason Gnome really wants to remember what files you’ve been messing with. Personally I never use this menu item (usually under Places in the Gnome Main Menu) and find it to be a bit of a privacy concern.

Surprisingly enough there are no documented settings for Recent Documents, not even something in gconf-editor, so people have been going stone age to prevent this functionality. In the past you could change permissions for the file that stores the data in your home directory, but it seems in later versions of Gnome the following is the current method of choice.

I’ve always had some trouble with the syntax for accessing Nested Arrays and their Keys in PHP so I wanted to make note of this.

So my reckless typing really got me into trouble this time. I was attempting to zero-out a usb drive when I managed to put the wrong device in the dd command - I automatically typed sda1 (the primary HD) out of habit instead of sdb1 - the usb drive. I caught my mistake and gave it a solid control + c but I had still wiped out the first 60 MBs of the drive.

If you lose any of your user passwords - including root you can change your password booting into single user mode. What you aren’t likely to find off the bat is the proper instructions to do it. They are out there, but chances are you will have to dig a little after some frustration. The main differece between all those super simple solutions and the one mentioned here is that you need to remount the OS drive in order to properly write your changes. This method has worked with the last three major releases of Ubuntu including Feisty. So, here’s the procedure…

I was trying to play some .avi files tonight with various players using the Xine engine, including Totem and xine-ui. I was getting an error like “there is no demuxer plugin available to handle … .avi” And even Amarok (which also uses xine) was complaining about playing .mp3s.
