Coming from Debian/Ubuntu camp, I know that ifup eth0 or ifdown eth0 can be used to bring a network interface down/up. Unfortunately, ifup and ifdown is not available by default on an Arch netinstall. Also, it seems like ifup/ifdown are now in the list of deprecated tools. So, what's the alternative? Use ip  command, like to bring down an interface do: #: ip link set eth0 down Conversely, if you want to bring up an interface, do: #: ip link set eth0 up Enjoy!

Linux Mint 12 was released last 2011-11-12. The release made it to the top of the list in Distrowatch.com. Looking at the outside, Linux Mint 11 and Mint 12 are almost identical except for minor verbiage change. Linux Mint 12 comes with the following major software: kernel:  3.0.0-12-generic X Org:  1.10.4 GNOME: 3.2.1 Firefox: 7.0.1 Below is my configuration of the guest machine: General Name: mint12 OS Type: Ubuntu System Base Memory: 1024 MB Processor(s): 1 Execution Cap: 100% Boot Order: Floppy, CD/DVD-ROM, Hard Disk VT-x/AMD-V: Enabled Nested Paging: Enabled Display Video Memory: 12 MB 3D Acceleration: Disabled 2D Video Acceleration: Disabled Remote Desktop Server: Disabled Storage IDE Controller   IDE Secondary Master (CD/DVD): Empty SATA Controller   SATA Port 0: mint12.vdi (Normal, 20.00 GB) Audio Host Driver: Windows DirectSound Controller: ICH AC97 Network Adapter 1: Intel PRO/1000 MT Desktop (NAT) Serial Ports Disabled USB Device

Work in progress!!! I have been pretty intrigued with Arch Linux for sometime. I have read numerous times in Distrowatch forum that this distribution can easily replace Ubuntu and that Ubuntu actually makes the name of Linux bad. It is touted by most that it is one of those real Linux, in the same ranks as Debian or Gentoo. My recent experience with Ubuntu 11.10 and Linux Mint 12 on VirtualBox were not good to put it mildly. Now I am in quest for the best Linux distro that can be installed on VirtualBox. By the way, Ubuntu 11.10 works like charm on VMware ESXi 5.0. Should I just dump VirtualBox? Maybe not just yet. With VirtualBox, I can run it on Windows and Linux and still be productive. With VMware ESXi, I need to dedicate a machine for that. I do have 5 boxes running VMware ESXi for software testing but I do need access to Windows on my work laptop. I can also move to VMware Workstation but I have higher hopes for VirtualBox as it is developed at a much faster pace. Plu

Is it just me or GNOME 3 based distributions are getting buggy? I have tried Ubuntu 11.10, Linux Mint 12, Fedora 15 (I should update to Fedora 16 soon), but I can't help but complain about the performance of this latest distributions virtualized using VirtualBox. Or is VirtualBox that's getting really buggy??? :( Ubuntu 11.10 feels really slow, clicking on an application using Unity takes forever to bring up the applications main GUI (even gedit is slow). Linux Mint 12 while looks nice but also is problematic. Clicking on Mint Menu shows blank items ... and it only shows up the entries once I wiggle the mouse around. Picture speaks a thousand words, so see below. Figure 1. Mint Menu shows blank on the left side :( Another issue I have observed with Linux Mint 12 is that the menu gets out of sync. So like if select Internet it does not move focus to it. But the items to the right gets updated. Again, see below for a screen capture. Figure 2. Menus are out of syn

Linux Mint 11 (Katya) was released 2011-05-26. As usual it comes with all the goodies but this time user can download an ISO without all the codecs. Below shows version numbers of the major packages.

With Ubuntu 11.10 Unity requiring lots of resources both in CPU and memory, I embarked on installing a trimmed down version of it using alternate install. This used to be straight forward, follow the text based wizard and you are ready to go. The problem is that after installation, on reboot it shows a blank screen. Just nothing... (except for the blinking cursor). This might be specific to VirtualBox guest machines but I can't verify this. Anyway, it took me a while to figure this one out (of course with the help of Google). The following, from  Ubuntu's bug repository Launchpad, shows the problem: Ubuntu 11.10 Command line only installation fails over and over again http://ubuntuforums.org/showthread.php?t=1873069 grub2 configuration has vt.handoff=7 even when X11 is not installed https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/695658 Command-line Install on Minimal CD tries to boot graphically https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/831752
