Xorg.0.log

same thing with today's git intel driver and xorg-server-1.3.0.0

Looks like a neat little machine, too bad we can't properly detect the panel.

You could try modifying i830_lvds.c to force it to grab the current panel mode (add "|| 1" or similiar to the end of the line that says:
  if (dev_priv->panel_fixed_mode == NULL) {
or add a new quirk for your device in i830_quirks.c if you can.

Hopefully that'll get the new driver up and running for you.

Uli, any problem in trying comment#4?

Jesse, are you able to add the quirk?

Uli, can you try running the attached program on your system (make sure you have ACPI enabled in your kernel).  If it works, it means we just need to add ACPI EDID detection to the X server, otherwise something else is going on...

Also, please attach the output of 'ls -R /proc/acpi' from your system.

Sorry this one has taken so long to work out.

Thanks,
Jesse

since bz doesn't seem to want to let me attach the file, here it is inline.

Uli, any chance you can try out the program in this bug?

Thanks,
Jesse

Reassigning to Hong as I think he'll take care of this one along with the rest of the LVDS initial mode bugs.

uli, if no response from you, we will have to close this bug...would you please test as comment# 7 and comment# 8?

It's a shame if we can't find a tester for this one... I suspect several laptops have similar problems, and it would be good if we could figure out how to get EDID data from ACPI to make them work.  Oh well I guess the code is easy enough to put together if we end up seeing something similar in the future.

last ping...

reject this bug due to no response from bug reporter..
