Asus UL80Vt and UL30Vt Linux: nvidia switch on/off



If you've got a Asus UL80Vt or UL30Vt and you have tried to use Linux on it, you may have noticed that the BIOS won't allow to switch on/off the nvidia card in 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.

  1. Somehow I can only get it to work with the default intel drivers. Installing any nvidia driver causes X to crash. Anoyone else seeing this?

  3. Nvidia still not working after I tried a few suggestions like BusID and displaydevice in xorg.conf. Read in UL50 forum that some BIOS versions allows preboot GPU selection but its not available in UL80VT. I think ASUS should include this feature in their BIOS.

  5. if anyone ends up here with no answer. you can set the bios option of the sata mode to compatability. this will disable your intel gfx. but also reduce HD IO performance. but you'll get the nvidia gfx to work with the hardware drivers
