Chrome Os Build Problem: Cannot Enter Chroot

Fri, 20 Nov 2009 01:34:11 +0000

On my Ubuntu 9.10 installation, I am trying to build Chromium OS for my Acer Aspire One. I run make_chroot.sh, and it works fine. I try to "enter_chroot" only to find that it mounts chroot and unmounts it as quickly as it began. I then run commands only to find that it in fact didn't enter chroot like it was supposed to. Other builders: Can you please help me on this? Why is it failing to enter chroot and not telling me why?

What, if any, terminal command shows me information about the file system Karmic is running (i.e. ext3 or 4)?

Wubi Vista: Grub Command Line, But Not Loading Wubi

Sun, 15 Nov 2009 23:48:10 +0000

I have a serious problem with Wubi 9.10 in Windows Vista: I install Wubi and reboot. The installation completes, and it reboots again. Once Ubuntu fully installs, and I do everything right, suddenly the "sh:grub>" prompt comes up, and I have to enter commands just to boot Ubuntu. Why?! Did the Menu.1st file get erased upon installation (or something)? And how do I fix this?

Switch Between Gnome And Kde Desktops In Ubuntu Or Kubuntu

Thu, 12 Nov 2009 08:23:09 +0000

One of Linux strong points over Windows is the capability to switch desktops. Several exist, but the two most popular are Gnome and KDE. For Windows users, KDE will have a familar Windows XP feel, while Gnome may seem dull.

If you have been using Ubuntu, which uses Gnome as the default desktop, or Kubuntu which uses KDE as the desktop, and have been wondering what the other desktop looks like, you can easily install KDE or Gnome and switch back and forth before logging on to Ubuntu.

If you are running Ubuntu, you can install KDE by opening a terminal window and type:

sudo apt-get install kubuntu-desktop

When prompted, enter your password, and then answer yes (Y) when asked if you want to install. The install may take some time to complete, so be patient.

To install Gnome in Kubuntu, open a Terminal window and type:

sudo apt-get install ubuntu-desktop

When prompted, enter your password and continue with the install until it has been completed.

Now reboot either Ubuntu or Kubuntu. Then at the logon screen you can either press F10 or click on the Options logo at the bottom (left side) of the login screen. Then click on Select Session…

Here you can select Gnome (2) or KDE (3) by selecting the radio button.

To change back to either KDE or Gnome, press F10 and select the desktop manager of your choice.

If you changed from the previous desktop manager, you can make it the default at the next logon.

How To Create Internet Shortcuts In Linux

Sun, 08 Nov 2009 22:41:05 +0000

Here's how to create shortcuts to Web pages in Linux:

Right-click the desktop and click "Create Launcher". The name of the Web page should be typed into the "Name" box.

The "Command" box should look like this:

firefox http://...../

where "....." is the name of the URL. Here's the properties of an example shortcut (the one for these forums):

New To Linux? Try Mandriva..!

Sun, 08 Nov 2009 20:10:23 +0000

As a new user to linux I tried a few distros on "live cd" nice and easy, Try the distro without any problems with your exisiting OS. A great idea for those who just want to try the Linux thing. So thats what I did, With a completely open mind, but with the media exposure that Ubuntu is getting, I thought, this might be the one for me. In short, I had an old PC and I wanted to try Linux on it, I had read reports about how Linux can work so well on old hardware. After trying in the region of six distros, the final choice was.... Mandriva. Easy to use, easy to install and hardware friendly. Want to try the Linux thing? Try Mandriva, you just might like it !

Netflix In Ubuntu

Tue, 03 Nov 2009 11:35:18 +0000

Have any of you Unbuntu gurus found a way to stream Netflix over Ubuntu? I tried but got a "We're sorry, your browser is supported but your operating system isn't" error message. I'm not sure what my OS has to do with anything but there you have it. I was interested in seeing if anybody has devised a work-around for this.

Gnome 3.0 Coming March 29th

This development release will become the 3.0 release when it's final. Yes, finally! You can transform your current GNOME Desktop to look like the final 3.0 using GNOME Shell.

Looking Ahead: Ubuntu Lucid (aka 10.04 Lts)

Sun, 01 Nov 2009 05:58:00 +0000

https://wiki.ubuntu.com/LucidReleaseSchedule

Exactly 6 months after Ubuntu 9.10 was released, there will come 10.04 LTS, aka "Lucid ". Here's my expectations:

GNOME 3.0 is a must. Yes, it will come out before Lucid, in March. I suspect this to be the reason of the Long Term Support. GNOME 3.0 will put GNOME Shell as the default interface. I personally am running GNOME Shell as I am posting. Excellent interface!

I would also love to see more kernel-based support for hardware. Perhaps the Ubuntu development community should run "sudo make xconfig" in the kernel directory before compiling into a .deb file, and enable every possible feature, turning all of the boxes into checks that they could possibly find.

What would you like to see in Ubuntu 10.04 LTS? This is pure speculation.

Linux Kernel Build Instructions

Fri, 30 Oct 2009 00:26:13 +0000

Okay, here's how you compile the Linux Kernel source code once you download the latest source from http://www.kernel.org/ :

You would extract it with the Archive Manager in Ubuntu Linux. By default, it should automatically load.

You should move the Linux Kernel Source Folder to /usr/src and rename the folder to linux.

Make sure you have Qt3 installed. Once you do, run

$ make xconfig

at the shell.

This should give you this configuration app:

Once you are done configuring the build process, it's time to build the kernel by running

$ make dep && make clean && make bzImage && make modules

You should copy the /usr/src/arch/i386/boot/bzImage file to /boot, renaming it to vmlinuz.

Copy the System.map file to /boot as well. When you are done, run

$ make modules install

at the shell.

Edit the /boot/grub/menu.1st file to include the new kernel. Type

title My new kernel
           root(hda, 0)
           kernel /boot/vmilnuz

After this, you're all set!

Linux Forum Documents/wikis

Sat, 24 Oct 2009 23:48:01 +0000

You can find the Linux forum Documents here: http://wiki.pcworld.com/index.php/Category:Linux

These are Wikis (what were called Documents under the old forum software) that correspond to this forum. They will generally explain how to deal with some common issues that have been previously discussed (some times multiple times) in the Linux forum. The idea is that these documents might offer a solution to a problem that you might be having without you having to ask a question in the forum.

Please feel free to take a look at them. And if you have a new document that you believe might be of value, then feel free to take a stab at adding it to the selection of Wikis/Documents.

Getting Wireless On Pc With Linux

Wed, 21 Oct 2009 02:41:32 +0000

My brother gave me a Linksys card for my old PC - no software, no instructions.

I have a wireless system for my Macbook - bought a Time Capsule - but I have no idea where to start to see if I can get the old PC laptop to access it. I don't even know if the card is working or being recognized!

Wireless is completely new to me. I think the Mac did its setup pretty much automatically so I'm going to need pretty detailed info on getting the PC to work this way.

First step is to confirm the card works and is recognized. This is a bigger deal than normal because of a card I used for something totally different that didn't work. I never knew if the problem was the card or if the slot didn't work properly.

Can't Get Into Linux

Wed, 21 Oct 2009 00:56:13 +0000

Okay, maybe I screwed up and just forgot something - I do that a lot lately (hate getting old). I set up my old PC to run both XP and Ubuntu some time ago. Even got a new hard drive for it since the old one was dying.

But I hadn't actually done anything with it for months. When I tried to boot it the other day into Linux (XP was fine), it wanted me to sign in with a name and password. Frankly, I don't remember this happening before, but I tried various combinations, none of which worked. So, how can I get back into this thing with the least fuss?
