After installing Ubuntu 8 Hardy Heron at the office, I was having trouble reaching the ‘.local’ DNS entries we have on our internal network. Here’s what I did to resolve the problem:

$ sudo vi /etc/nsswitch.conf

Replace:
hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4

with:
hosts: files dns

Here is how to control which application Firefox uses to handle MMS streams:

Type about:config Firefox address bar.

Right-click on any text in there and select “New” and then “String”.

In the first dialog box, as preference name, type network.protocol-handler.app.mms.

In the second dialog box, as string value, type in vlc (or the path to your favorite media player)

Here is the command to use to mount an ISO file in Linux so that you can explore the file as if it were mounted on a CD-Rom or DVD-Rom, without having to burn to a disc:

sudo mount -t iso9660 -o loop filename.iso /folder/to/mount/to

This functionality is similar to Daemon Tools or Alcohol on Microsoft Windows.

Here’s how to make F-Spot your default application for importing photos from your digital camera in Ubuntu Gutsy 7.10:

System -> Preferences -> Removable Drives and Media. Click the ‘Cameras’ tab. Check the box next to ‘Import digital photographs when connected’. Enter the following for ‘Command:’:

f-spot-import %h

Now when you plug a digital camera into the computer, F-Spot will open and prompt you to import your pictures.

Via Mais on Ubuntu Forums:

Purpose: For many of us, our laptop touchpads get in the way of our typing quite often and can actually cause us to highlight or minimize things we didn’t intend. So, this will help to alleviate that by making a small delay in the response of the touchpad after typing.

NOTE: Please read this guide entirely before attempting to do it. There is a section where you must restart X and thus close down your internet browser. The best way to do this would be to print this guide! I hope this works as well for you as it has for me!

Procedure:
1. Turn on SHMCONFIG
A. Open a Terminal. Applications -> Accessories -> Terminal
B. Type sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_synbackup

C. Type gksudo gedit /etc/X11/xorg.conf Enter your password if it prompts you.

Note: The second command in the picture is typed wrong. Please see C.

D. Search for a section that looks like this:

Section “InputDevice”
Identifier “Synaptics Touchpad”
…
End Section

E. Add a line above the End Section line and put this into it:

Option “SHMConfig” “on”

F. Save the file and close gedit and the terminal window
G. Write these commands down just in case this screws up your window system: sudo cp /etc/X11/xorg.conf_synbackup /etc/X11/xorg.conf and sudo killall gdm and sudo gdm
H. This next step will restart your window system, so save any work and close any open applications. Press: Ctrl-Alt-Backspace. This should take you back to your login screen. If it does not, press Ctrl-Alt-F1 and login at the terminal window. After logging in, type the commands that you wrote down from step F in order hitting return after each command.
I. If your login screen came up the first time, continue on to part 2, if not, look over waht you did carefully and see if you can spot any mistakes.

2. Add the Startup Command
A. Open the sessions manager: System -> Preferences -> Sessions
B. Click the far right tab labeled Startup Programs
C. Click the Add button
D. Type in the following: syndaemon -i 1 -d

E. Hit ok then hit close

Congratualations, you are done! Note that this will not take effect until Gnome is restarted or you type the command from 2D in a terminal window. You can restart Gnome with the Ctrl-Alt-Backspace trick (make sure to save everything first!) or you can open a terminal by going to Applications -> Accessories -> Terminal.

If you have any questions, comments, or concerns, feel free to contact me through this board, or more easily through email or AIM.

I installed Second Life 1.18.4 (3) on Ubuntu Gutsy 7.10. Everything seemed fine for the most part, however the audio from music streams in the game was very crackly. Second Life is the only application with crackly audio, all my other applications seem fine so far.

I corrected this by installing the “esound” package, and then rebooting my machine.

$ sudo aptitude install esound

After rebooting and trying again, sound now works perfectly in the game.

I’ve been experimenting with Ubunty Gutsy 7.10 on my (relatively) new Asus A7T notebook. For the most part, everything works well after the install, but there are two annoying problems that I ran into:

1. No sound. My laptop uses the ALC882 codec.
2. When I boot up, there is no bootup screen, or splash screen. All I see is a black screen until GDM starts. Also, if I switch to a TTY terminal screen using CTRL+ALT+F1 (through F6), the resolution is incorrect; everything is huge and off the screen by several lines, which renders it pretty useless.

Here is how I have fixed both of these issues:

Fixing Sound

I was able to fix my sound issue using the alsa-base package installed by default (version 1.0.14-1ubuntu2 at the time of this writing). Here are the steps:

A. Create a new file called “/etc/modprobe.d/snd-hda-intel.modprobe”:
$ sudo gedit /etc/modprobe.d/snd-hda-intel.modprobe

Add the following line to the file and then save it:
options snd-hda-intel model=w2jc

B. Edit the file “/etc/modprobe.d/alsa-base”:
$ sudo gedit /etc/modprobe.d/alsa-base

Add the same line to the end of this file and then save it:
options snd-hda-intel model=w2jc

C. Reboot. After I rebooted, I had sound.

Fix TTY and boot-up resolution

A. Edit the file “/etc/initramfs-tools/modules”:
$ sudo gedit /etc/initramfs-tools/modules

Add the following two lines to the end of the file, then save it and close it:
fbcon
vesafb

B. Edit the file “/etc/modprobe.d/blacklist-framebuffer”:
$ sudo gedit /etc/modprobe.d/blacklist-framebuffer

Comment out the blacklist vesafb, so that it looks like this: #blacklist vesafb

C. Set the height and width values in usplash.conf to 1024×768:
$ sudo gedit /etc/usplash.conf

Change the values to 1024×768, save the file and close it.

D. Edit the grub config file to add a vga value to set the resolution of the bootscreen to 1024×768:
$ sudo gedit /boot/grub/menu.lst

Find the commented out #defoptions line. Leave it commented out, but add the following to the end of the line:
vga=773

Save the file and close it.

E. Regenerate initram file:
$ sudo update-initramfs -u

F. Update grub:
$ sudo update-grub

G. Reboot. After I rebooted, I saw the bootsplash, and my TTY terminals were at a better resolution.

Here is how I configure my Alt+Print Screen action for taking window screenshots:

First, install gconf-editor if you don’t have it already:
$ sudo aptitude install gconf-editor

Then, open gconf-editor with this terminal command:
$ gconf-editor

Navigate to:
/apps/metacity/keybinding_commands/command_screenshot

Change the ‘command_window_screenshot’ value to:
gnome-screenshot --interactive --window --delay=1 --include-border --border-effect=shadow

Now when you use Alt+Print Screen to capture a screenshot of a window, you will get a nifty little drop shadow behind your image by default. See the example below.

Welcome to the Linux Alternative Project (formally the Linux Equivalent Project). The goal is to provide an informational and available website for all linux users. The website is currently in beta form. I will be periodically updating the database with Windows software and the Linux equivalents and alternatives.

In Ubuntu, you can use the SMB protocol (Server Message Block), a.k.a ‘Samba’, to share folders from your Ubuntu Linux workstation with Microsoft Windows workstations on your network.

I use SMB to share folders between my Ubuntu workstation and my Windows XP virtual machine in VMWare Server. Note that other virtualization products, such as VMWare Workstation and VirtualBox, come with this feature built-in.

In my virtual machine, I have the ethernet card set to ‘Bridged’ so that it connects to my physical network and is assigned an IP address from my router, as opposed to sharing the IP address from the Ubuntu host using NAT. You will need to know the Workgroup that the Windows XP machine is in. You can find this by going to Control Panel -> System and clicking on the Computer Name tab. You will see the Workgroup identified there.

Now, in Ubuntu, click System -> Administration -> Shared Folders. This will prompt you for your sudo password. If this is your first time visiting this control panel, it may prompt you to install SMB and NFS support, which you should do. Once that is finished, you will be presented with the Shared Folders applet. Click Add, choose the Path to the folder you want to share, choose ‘Windows networks (SMB)’, and enter the user name that you want to allow access to this share. You can also specify whether the user will have read-only access or read-write access. Click OK.

You are now sharing a folder. However, if you try to access the folder from Microsoft Windows at this point, you will be prompted for your password over and over again. The documentation in Ubuntu fails to tell you that you need to configure the user name that you want to use to access the share.  The default configuration requires users to enter a user name and password to access the share. You can do this from the command line:

$ sudo smbpasswd -a <USERNAME>

Replace <USERNAME> with the user name you want to access the shares. That command will respond with:

New SMB password:

Type the password you want to use, then confirm it. You should now be able to access the share via Windows with that user name and password.
