I get very jerky video playback and unsynchronised soundtrack of all type of files. lsmod produces the following output with reference to VIA.

I used the one-click restricted codecs install. Could someone please point me to a diagnostic howto procedure? Thanks in advance.

I’m assuming that this will have to do with the very basic graphics chipset in use. You might want to investigate using the openchrome driver (which appears to support your hardware):

freedesktop.org - Openchrome

I note that the openchrome package is available for openSUSE 12.3:

software.opensuse.org:

You may need to configure Xorg as explained here

That’s about all I can offer. Hopefully, others with this hardware can comment /advise further.

Thank you very much for the speedy response and wonderfully simple solution. Everything works fine now.

Great. I’m glad that the driver worked for you. :slight_smile:
