OpenGL shaders not supported-widget problem


Greetings,
While I try to add Blue Marble widget I get this error "OpenGL shaders not supported". It's weird considering everything else on kde works great and my laptop configuration is Dell Core2Duo T 6500 2.1Ghz. Should I install any extra packages to make it work?. Also any tips/suggestions/links about improving the look and appearance of Slackware would be most welcome.
Thanks in advance.

Edit:
I am using Slackware 13.0 32-bit if that helps.

The important factor is your video card and drivers. What are you currently using?

oops. Forgotten that.
Intel Graphics Media Accelerator X4500HD is what i use. And I haven't downloaded any special driver packages for it because i couldn't find any. According to wikipedia, GMA supports OpenGl and found this

Intel has had a long history of producing or commissioning open source drivers for its graphics chips, with all chipsets (except the GMA 500) dating back to the i810 having open 2D and 3D drivers for Linux. Intel is the only major graphics hardware vendor to do so. (For an analysis by company see Graphics hardware and FOSS.)

In August 2006, Intel added support to the open-source X.Org/XFree86 drivers for the latest 965 series that include the GMA (X)3000 core.[60] These drivers were developed for Intel by Tungsten Graphics.[61]

In May 2007, version 2.0 of the driver (xorg-video-intel) was released, which added support for the 965GM chipset. In addition, the 2.0 driver added native video mode programming support for all chipsets from i830 forward. This version added support for automatic video mode detection and selection, monitor hot plug, dynamic extended and merged desktops and per-monitor screen rotation. These features are built in to the X.Org 7.3 X server release and will eventually be supported across most of the open source X.Org video drivers.[62] Version 2.1, released in July 2007, added support for the G33, Q33 and Q35 chipsets.[63] G35 is also supported by the Linux driver.[64]

As is common for X.Org drivers on Linux, the license is a combination of GPL (for the Linux kernel parts) and MIT (for all other parts).[65]

The drivers were mainly developed by Intel and Tungsten Graphics (under contract) since the chipsets' documentation were not publicly available for a long time. In January 2008, Intel released the complete developer documentation for their, at the time, latest chipsets (965 and G35 chipset), allowing for further external developers’ involvement. [66] [67] In April 2009, Intel released documentation for their newer G45 graphics (including X4500) chipsets. [68] In May 2009, Intel employee Eric Anholt stated Intel was "still working on getting docs for [8xx] chipsets out." [69]
from http://en.wikipedia.org/wiki/Intel_GMA.
So I guess Linux would support mine without any additional drivers.
Thanks for your time.

Yes, your card supports opengl without any extra drivers. However, the drivers available in Slackware 13.0 apparently do not support the necessary shaders for that plasmoid. The only drivers that I know handle this are the proprietary nvidia and AMD drivers. I've recently asked on the #radeon IRC channel about what it would take to get the plasmoid working properly with the open source radeon driver (I assume the requirements would be similar for the open source intel drivers) but have no heard back yet.

If I had to take a quick guess, I would say that the plasmoid requires GLSL version 1.2 or higher, and I think all the most any of the open source drivers support is GLSL 1.1.

Hmm..
After a little bit of googling i found that the problem exists in other distros as well.
http://ubuntuforums.org/showthread.php?t=1053182
One suggestion made at the opensuse forums was to install the compiz package.
http://forums.opensuse.org/applicati...supported.html

Unfortunately it seems compiz is available only for 12.2 and not 13.0.
What the heck, I can live without this anyways.

One more question:
Is there any way to know the entire system configuration like graphics card(I know this but still would
like to know from the software)via any commands/packages.
Coming from windows background, I used a s/w called sisandra there.

compiz won't get the blue marble plasmoid working. The person who wrote that is definitely mistaken. It really is just a limitation in the drivers (or the GPU itself).

I'm not aware of any particular utility that will provide even the smallest details on your system, but there are many individual utilities, such as dmidecode and lspci. Actually, the KDE Info Center will have nearly all of this information.

KInfoCenter is good. I guess there is a lot of useful stuff in KDE that I haven't checked out as i was focused on CLI stuff for installing packages for sometime.
Thanks a lot, Adam.
