(peek in http://lekensteyn.nl/files/get- > acpi-info.sh, you do not have to run all of the commands since I already have > your acpidump) Ok, because I have an ecrypted root fs I've tried to reload the i915.ko with CADL after booting. Test-results: - asus_wmi.ko doesn't seem to have any effect whatsoever on the endresult. - asus_nb_wmi.ko doesn't load (ENODEV). - brightness-keys (and also sound control) don't work, but controlling the backlight with /sys/class/backlight/acpi_video0/brightness works (if I can turn the panel on somehow, see below). - When loading the i915.ko with the CADL patch the screen went black (like at boot), but with some excessive vt-switching and X restarting I've managed to light it up. Although it is flickery as hell, especially the lower part of the screen. And if the screen is somewhat stable, I just get the upper part of the screen duplicated in the lower part. - dmidecode is attached. - no errors in the logs anywhere (if you ignore some ACPI resource conflicts because ACPI reserves some pch stuff itself, which then conflicts with the native gpio, sensors, whatever drivers). So I think this might be simply a timing issue that with CADL enabled we expose a pre-existing bug somewhere in our modeset sequence. I'm already chasing two issues on this machine: - edp refuses to light up crtc 1/2, only works after having switched back to crtc 0. - disabled pipes get stuck in the active state once having been used be edp. I have a feeling that all these issues are related, so I guess until I've tracked down the above the things we won't make much progress with this CADL patch. Still, if you have any insights or need more dumps/logs from my machine, I'll happily help out. Cheers, Daniel -- Daniel Vetter daniel.vetter@xxxxxxxx - +41 (0) 79 364 57 48 - http://blog.ffwll.ch
