Google Chrome BETA for Linux is OUT .... Finally !!!

The first thing I did after installing it on my linux desktop was to uninstall Google Chrome in my Windows VM.

I'm not sure why it took so long but if my experience on occasionally using it inside a windows VM is any indication, it's worth the wait.

Coinciding with the release of the Linux and Mac versions of the browser is the opening of the extensions gallery (think Firefox Add-Ons).

 I'm still looking but I haven't found anything like Mozilla Weave or Opera Sync yet.

Here's coverage from some of my favorite sites around the web :

Build your own distro with Suse Studio

Countless are the times when I had wished that there was a linux distribution with exactly the stuff I need and none of the bloat. With the Alpha release of Suse Studio, that wish is about to be fulfilled.

Suse Studio allows you to customize OpenSUSE with just the software you need thru an easy to use web interface. The end result can be an ISO, Disk, VMware or Xen image.

WOW

Kernel upgrade to 2.6.22.16-0.1 and minor MadWifi inconvenience

The opensuse updater applet upgraded my kernel and the nvidia graphic card drivers on my opensuse 10.3. Everything was ok except Wifi stopped working.

I have a T61 with the Atheros chipset using MadWifi. It seems the MadWifi repositories haven't caught up. Luckily you can search for updated MadWifi rpms from software.opensuse.org/search.

So first things first is to check what my new kernel is ....

uname -r

Next I search for madwifi-kmp-default that matches the kernel I'm using on http://software.opensuse.org/search and I click on the "One click install" icon to install it.

NVIDIA Driver 169.07, Compiz and OpenSUSE 10.3

I left my PC to update overnight and I was surprised this morning after a reboot that Compiz isn't working anymore.

It seems the OpenSUSE updater upgraded the Nvidia drivers to version 169.07 but it broke Compiz in the process.

After some exhaustive googling I found the solution in this blog. It's in Italian and it seems meant for Ubuntu users but the code snippets were easy enough to follow and they worked for me on OpenSUSE 10.3

After installing the updates and rebooting, I noticed that compiz wasn't working anymore so I manually executed compiz from a gnome terminal and got this error ....

“No GLXFBConfig for default depth”

The solution according to M0rF3uS’ Ubuntu Blog is to execute the following in your terminal

LIBGL_ALWAYS_INDIRECT=1 compiz -–no-libgl-fallback -–replace ccp &

Alternatively, if you use fusion-icon to launch compiz, open the file

/usr/lib/python2.5/site-packages/FusionIcon/data.py


and locate the line with compiz_args.

edit it so that it looks like

compiz_args = [’–replace’, ‘–sm-disable’, ‘–ignore-desktop-hints’, ‘ccp’, ‘–no-libgl-fallback’]

Then, open a terminal and execute

LIBGL_ALWAYS_INDIRECT=1 fusion-icon

UPDATE: This latest version of the NVIDIA drivers fixed the function keys that control the brightness on my T61. This means that I don't have to exit X windows anymore to adjust the brightness.

Pulse Audio the "Compiz for Audio" on OpenSUSE

Fedora 8 made waves with Pulse Audio when it was released. It was such a hit that other linux distributions are following suite. OpenSUSE 10.3 users (yours truly included) can now install Pulse Audio using the one click install.

So what's the big deal over Pulse Audio ?
  1. With Pulse Audio, you can run multiple applications (e.g. skype, pidgin, flash video on firefox, Banshee) that use sound and you can hear them all at the same time, even go so far as to control the volume for each application.
  2. Works with or over existing audio systems like ESD for Gnome and aRTS for KDE.
  3. From Linux.com : "PulseAudio can route audio from multiple sources to multiple sinks, both locally and over the network. You can use it to combine multiple soundcards into a single virtual device, to forward music from one PC to another, or to share a single microphone as an input between multiple PCs." Cool !!!
It was an easy installation, the one click install did most of the work for me, although I still had to do a couple of additional things to get it to work. If you happen to have OpenSUSE 10.3 with GNOME, use the one click install and try the following to get Pulse Audio up and running :
  1. After the one click install completes, login as root and edit /etc/group and add all the users who will use Pulse Audio on your system to the pulse group.
  2. Reboot your system
  3. Login as a desktop user, in the Gnome Control Center click Sessions.
  4. In the Startup Programs tab click Add
  5. Type PulseAudio Server on the name field.
  6. Type pulseaudio & on the command field.
  7. Locate and run the PulseAudio Device Chooser from your Application Browser
  8. Logut and then login again.

Get a screenshot of an X server running in the background

Ok, before I completely forget about this again.
To capture a screenshot of a running X server instance in the background,

On a linux terminal type ...

DISPLAY=:X import -window root xvfb.png

where X is the display number where the X server is running at and xvfb.png is the output, the file with the screenshot.
