No external monitor with Fujitsu U810/11.1

[whirly450]

Just upgraded from 10.1 to 11.1 on a Fujitsu U810 with Intel 945 GM graphics. External LCD (through VGA port) worked great in 10.1, but doesn't work at all in 11.1. I enabled dual-head etc. in sax2 exactly as in 10.1, but no external LCD (tried three different ones) is ever detected in 11.1. All available updates have been installed.

xrandr showed that the external LCDs are being detected as "TV-1" and VGA is always listed as disconnected. So I went into xorg.conf and told it to ignore "TV" and "TV-1". Now xrandr doesn't list TV-1 anymore but VGA is still disconnected and the external monitor(s) still don't work.

Tried xrandr --output VGA with various modes, no change. Also tried different resolutions for the external monitor, including just cloning at 800x600, no change. The Fujitsu has a "Fn-A" keyboard to toggle external displays; no change there either.

xorg.conf is posted below, including the ignore TV and TV-1 modifications. I noticed that SaX identifies the external LCDs as "EXT" but there's no section for "VGA" in xorg.conf. Changing "EXT" to "VGA" doesn't help.

Any help would be greatly appreciated! fyi, I am fairly experienced with command-line Linux but not so much with X11. :-)

thanks in advance...

It looks like no one has an answer for this.

OK, here's another question. Since the external monitor worked fine from the same machine in 10.1 but not 11.1, what changed between the two versions? How can I find out if (for example) a new Intel 945GM driver was issued between those two versions? If there was, how can I downgrade to the old driver?

Any suggestions would be appreciated. Otherwise I'm stuck with that tiny U810 screen and no monitor/projector.
