Comment 3 for bug 394498

Hi Bryce, sorry for the delay in responding, I've been on holiday!

I'm not sure why none of the files attached to the report the DPI as 29x39. This was the DPI reported by xdpyinfo when running X without the DisplaySize hardcoded in xorg.conf or when X is started without the VGA cable attached to the PC. I've not used the command line bug reporting tool before. I was told to start X using the "broken" configuration and then start X with a "working" default then run the ubuntu bug command line tool. That's what I did, but I see that the xorg.conf and xdpyinfo output attached to the report is the "working" version, not the "broken" one.

I put a DisplaySize line in to xorg.conf, calculated as best I could following the formula given on the ubuntu forums, which suited my 32" TFT TV. This is a 16:9 display but I don't think the graphics card in the MPC-L computer supports widescreen resolutions, so I was aiming to run the display at 1280x1024. With this DisplaySize line in place, text is rendered clearly. Without it, text is tiny on the screen.

Having looked at the wiki page you posted above it seems likely that it is an EDID issue. The "Max Image Size" in the xorg log file is 10cm bigger in both dimensioons than the visible screen size on the TV. I'm not sure whether this is sufficiently incorrect to cause this error?

I have had this issue with Xubuntu and Openbox. Due to the very low spec of the CPU in the MPC-L it is very slow running KDE or GNOME. However, Openbox uses gdm AIUI and the issue is present there.
