I’ve jsut about had it with NetworkManager. Everytime I update my system I have to bite my nails wondering whether the update will break my wireless. I’ve posted earlier about my problems with NetworkManager and on howto fix it, there’s the best way to fix it: get rid of it.
Yeah, get rid of NetworkManager, install Wicd.
Here’s how:
Well I was browsing through some Kannada sites the other day and all I got was big blocks.
Turned out that Gentoo and Sabayon didn’t have support for displaying Kannada characters, though, I had no such problems with Hindi & Bengali characters [amongst others]. Changing the Character encoding in Firefox to Auto-detect or Unicode didn’t work either. After doing a bit of searching, found the solution. So open the terminal, switch to root user and type
emerge -av lohit-fonts
followed by
fc-cache -f -v
Restart your X server (ie, Logout, login) and you should be set!
Well like I mentioned in my previous post, as I upgraded my system to KDE 4.2, NetworkManager 0.70 was also pushed in the update, and that broke my wireless. NetworkManager didn’t detect *any* of my network devices(yup, not even the ethernet port). A small post on Sabayon forums and I got the confirmation that I wasn’t the only one facing this, and the only way (atleast for now) is to downgrade to NetworkManager 0.6.6-r1.
So incase you aren’t able to connect via wireless, fire up your package manager and downgrade to NetworkManager 0.6.6-r1.
In Sabayon, you can do so by first switching to root.
su root
Next install NetworkManager 6.6-r1
equo install networkmanager-0.6.6-r1
In case this version is not present in Sabayon repos (like for me) emerge it from Gentoo sources.
Here’s how. Type
emerge --sync && layman -S
and followed by
emerge =net-misc/networkmanager-0.6.6-r1
That should bring up wireless. Will post if any update fixes this.
Thanks to wolfden from Sabayon forums for helping me out with this
After countless days of waiting, KDE4.0, the first release of the KDE4 framework was released on Friday, January 11.
Here’s an official announcement from KDE’s site:
The KDE Community is thrilled to announce the immediate availability of KDE 4.0. This significant release marks both the end of the long and intensive development cycle leading up to KDE 4.0 and the beginning of the KDE 4 era.
The KDE 4.0 desktop
The KDE 4 Libraries have seen major improvements in almost all areas. The Phonon multimedia framework provides platform independent multimedia support to all KDE applications, the Solid hardware integration framework makes interacting with (removable) devices easier and provides tools for better power management.
The KDE 4 Desktop has gained some major new capabilities. The Plasma desktop shell offers a new desktop interface, including panel, menu and widgets on the desktop as well as a dashboard function. KWin, the KDE Window manager, now supports advanced graphical effects to ease interaction with your windows.
Lots of KDE Applications have seen improvements as well. Visual updates through vector-based artwork, changes in the underlying libraries, user interface enhancements, new features, even new applications — you name it, KDE 4.0 has it. Okular, the new document viewer and Dolphin, the new file manager are only two applications that leverage KDE 4.0′s new technologies.
The Oxygen Artwork team provides a breath of fresh air on the desktop. Nearly all the user-visible parts of the KDE desktop and applications have been given a facelift. Beauty and consistency are two of the basic concepts behind Oxygen.
Learn more about KDE’s new desktop interface in the KDE 4.0 Visual Guide.
Some applications are introduced in more detail in the KDE 4.0 Visual Guide.
Filemanager, System Settings and Menu in action
KDE’s TechBase knowledge library has more information about the KDE libraries.
The KDE 4.0 Visual Guide provides a quick overview of various new and improved KDE 4.0 technologies. Illustrated with many screenshots, it walks you through the different parts of KDE 4.0 and shows some of the exciting new technologies and improvements for the user. New features of the desktop get you started, applications such as System Settings, Okular the document viewer and Dolphin the file manager are introduced. Educational applications are shown as well as Games.
For those interested in getting packages to test and contribute, several distributions have notified us that they will have KDE 4.0 packages available at or soon after the release. The complete and current list can be found on the KDE 4.0 Info Page, where you can also find links to the source code, information about compiling, security and other issues.
The following distributions have notified us of the availability of packages or Live CDs for KDE 4.0:

Found this blog while surfing. Very useful!
These are some various linux/unix problems I’ve encountered over the years, but which I was not able to find a solution for online. Hopefully this will save you the trouble I had.

Problem:
Network interface (or anything else on the pci bus) says “SIOCSIFFLAGS: Resource temporarily unavailable”
Cause:
No IRQ assigned to the device, check /proc/pci (irq says 0)
Solution:
Enter the bios setup (F1 or Del on boot), disable the option ‘Plug n Play OS’.
Reason:
This will make your bios set up IRQs for you.
Problem:
USB mouse using /dev/psaux, the ps/2 mouse device.
Cause:
Bios usb legacy support in action, probably because Linux didn’t probe for USB devices (which causes the bios to release control of them).
Solution:
Compile the kernel with USB support, Input Core and USB HID.
Reason:
Duh.
Problem:
USB mouse still doesn’t work on /dev/input/mice, but /dev/psaux, even when USB support is compiled in.
Cause:
Legacy USB support again. You might not have compiled in support for your USB chipset (the UHCI parts in USB support).
Solution:
Compile UHCI. If not working, try the alternate drivers.
Reason:
Duh.
If there’s a better system repair kit than the Gentoo-based SystemRescueCD Linux distribution, we haven’t seen it yet.
The new 0.4 version of SystemRescueCd was released on Oct. 4. This new edition focuses on disk partitioning, Vista support, and data rescue tasks. In the past, we’ve found SystemRescueCD to be the best of the best when it comes to repairing troubled systems. We see every reason to believe that this version will be even better.
This edition is built on top of a customized 32-bit Linux 2.6.22.09 kernel. This kernel is named rescuecd. It also includes built-in support for the Reiser4 file system.
There is also just enough of a 64-bit kernel, rescue64, to use chroot on a 64-bit Linux system. The chroot system call changes the root directory of the current process and all child processes to a given path. For repair purposes, it is used to boot into an unwise unbootable system.
If you’re a Windows user, don’t let the fact that this is a Linux-based repair tool keep you away. SystemRescueCD has long excelled at repairing Windows systems. With new support for the Vista “Offline NT Password & Registry Editor” and improved support for NTFS drives, SystemRescueCD is better than ever for what ails your Windows PCs.
Another major improvement is that you can now use PXE network booting. With PXE, you can boot a troubled PC remote over your LAN into SystemRescueCD. This is great, for example, for a help desk repairing systems scattered over an office or campus. To get this to work, the PCs will need to be set to use wake-on-LAN and network boot. That’s been a standard PC feature since 2001, but it usually must be made active in the BIOS before you can use it.
The distribution is also just easier to boot up, period. In the past, you often needed to manually set boot parameters for a successful boot-up. It wasn’t difficult, but it could be time-consuming. Now SystemRescueCD is much better at analyzing its hardware environment and automatically booting with the appropriate configuration and drivers.
Starting with the version before this one, 0.3.8, the distribution also added serial communication tools: minicom-2.2, an ANSI terminal program with ZModem support; gtkterm-0.99.5, another popular terminal program; and ckermit-8.0.211, a set of communication programs usually used for file transfers. These are invaluable for those times when you have no other way to get into a broken computer except through a serial port connection.
Sometimes there are upgrades that you can ignore. The improvements aren’t big enough or upgrading the program is too much trouble. But, then there are updates that are so important or add so much to a program, you must make the upgrade. SystemRescueCD is a must-upgrade for anyone who does computer repair work.
