I very much appreciate your help.
Ihave elected for a fresh install and so far, so good. However that was the case once before. The problem sufaced after a while (One suspects an update.)
Here then (Just in case) is that output.
Graphics: Card: Intel Mobile 945GM/GMS 943/940GML Express Integrated Graphics Controller bus-ID: 00:02.0
X.Org 1.10.4 drivers intel unloaded: fbdev,vesa Resolution email@example.com
GLX Renderer Mesa DRI Intel 945GM x86/MMX/SSE2 GLX Version 1.4 Mesa 7.11 Direct Rendering Yes
If you see anything here that could be a problem later, I would really like to know. However like I said, so far so good. I shall retain my optimism for the fresh install.
