Thanks for confirming that this has no change. Did you see my post with the

I can understand that. No it makes no difference from which kernel this is run.
To be exact, it was somehow working as Linux did not check the information in
the DSDT close enough. So GFX0 might be the right device to look at but it
points to another pci device (supposedly one that does not exis
Ok, I can post the results, does it make the difference if I post results
from the 'normal' distribution and not from yours (modified)? That's so
weird, so previously it was working because no programmatic check was done
by DSDT? I agree, new bios should be tried, but since it's a critical step

I believe the BIOS is buggy with that respect (not sure why the DSDT compiler
freaks out but that might be a different issue). I manually looked up those
values in the DSDT you provided, so based on that data the kernel takes the
right steps. The question is whether the new BIOS fixes this or w

You need the space between . and /proc/acpi/video otherwise the grep won't
work. The . is the search argument.
