I'm running 12.04 32-bit on a P III 1133MHz with an NVIDIA 6200 256 MB graphics card. System Settings/Details shows Graphics Unknown.
Neither Firefox nor Chromium will display videos. For example, when trying to access TED videos, Firefox displays a blank screen where the video should appear and Chromium show a blank screen with a "Couldn't load plug-in" message.
Don't know if the Graphics Unknown and lack of video are related.
I have tried all the solutions offerred in other posts related to flash plug-in problems, with no good results.
Suggestions to get to a clean starting point, then some diagnostic help would be greatly appreciated. Maybe I need a newer computer or an older version of ubuntu?
