I am a new user and I just installed Blender 2.76b on a Lenovo R500, OS Windows XP Pro. I intend to use it mostly for (short) video editing. I could load, hear audio, cut and animate video correctly, but the preview is in a white square on a black background.
When I initialize Blender, I got the following output:
"AL lib: <EE> ALCdsoundPLayback_reset: Unknown system speaker config:0x0 Warning! Using result of ChoosePixelFormat."
and at the start this alert:
"Your system does not use 3D hardware acceleration. Such system can cause stability problems in Blender and they are unsupported. This may cause by: * A missing or faulty graphics driver installation. Blender needs a graphic card driver to work correctly. * Accessing Blender through a remote connession * Using Blender through a virtual machine"
Cases two and three are not mine. Do I need any special driver for my graphics card (ATI Mobility Radeaon HD 3400 Series) to use Blender? Does it have anything to do with seeing no preview?
