Hi All,

I've given it another try.

1. fresh clone from git
2. applied patch - ok
3. make; make install
4. reboot

At this point there is no TV connected. I can see from the Xorg log file
that it detects that there is no TV connected. There is an DVI panel
connected, though, so I would assume we get an image there. No. Xorg fails.

I changed via_output to force detection of the TV, as follows:

|static xf86OutputStatus||
||via_tv_detect(xf86OutputPtr output)||
||{||
||    xf86OutputStatus status = XF86OutputStatusDisconnected;||
||    ScrnInfoPtr pScrn = output->scrn;||
||
||   ||*/*if (ViaTVDACSense(pScrn))*/*||
||        status = XF86OutputStatusConnected;||
||    return status;||
||}|

retry: make; make install
reboot

As soon as we start up X, the box completely freezes. No response to
Ctl-Alt-Del, no ping, no display, nothing...

Reset the BIOS to default. Reboot. Same thing.

Moved /usr/lib/xorg/modules/drivers/openchrome_drv.* away.
Changed /etc/X11/xorg.conf.d/10-monitor.conf to have Driver "vesa"
instead of Driver "openchrome". Reboot.
We have a picture!

The other day, when I tried the patched driver when the box was
connected to a TV set, I had the same freeze. So I conclude:

a) the detection if there is a TV connected works.
b) there is something else in the TV code that makes the box freeze.
c) with only an DVI device connected, that state is not recognized.

Freezes like this are hard to debug, I figure, as there is no log to check.

Any clues from the community?

Regards,
Willem
