If you've got a BenQ Joybook S42 and you have tried to use Linux on it, you may have noticed that there are issues with the hybrid graphics setup. To help improve the Linux hybrid graphics support for this laptop, please attach your DSDT information to this Launchpad bug report specifying your laptop model:
https://bugs.launchpad.net/bugs/312756
To compile your DSDT information, install if you haven't already the acpidump and iasl tools:
sudo apt-get install acpidump iasl # on Debian-based systems
Then run the following commands:
sudo acpidump > acpidump.txt
sudo acpixtract acpidump.txt
iasl -d DSDT.dat
This will create a DSDT.dsl file that you can attach to the bug report. This information will allow the developers to fully implement the hybrid graphics features for Linux.
