V wanted to use the Toshiba AC-100 smartbook for projecting with its HDMI out. The Ubuntu 12.04 which I had loaded for him did not work with the Nvidia driver. Tried Lubuntu 12.10, with the proprietary driver. But system would hang when I used arandr to set output to HDMI only, no display on the projector. So tried restoring back to Android.As noted earlier, used the technique and the files as given earlier, and went back to Andoid. At first, I tried restoring only partitions 2, 3, 4, 5, 8 and 12 - the first few, and the biggest ones. But when the AC100 booted up, it went back to Lubuntu. Then I saw that in my previous post I mentioned partition 6 is the boot partition. So I restored partition 6, and hey presto, Android booted up.
With Android also, the HDMI out was not displaying on the Optoma projector. Suspecting the cable and order of switching on of devices, got the working HDMI cable from upstairs, switched off and disconnected both devices, connected the cable, powered on the projector and booted Android. Then the display came on flawlessly. Hopefully Documents to go will serve V's projection needs.
