nVidia G210m on Asus UL50VG laptop

[lanuser]

This about Asus' UL80Vt (some type of hardware)
CULV processors are typically paired with Intel's GS45 Express chipset, whose integrated Graphics Media Accelerator X4500MHD offers abysmal gaming performance and spotty compatibility. Fortunately, the chipset has 16 lanes of second-generation PCI Express connectivity, which the UL80Vt links to a GeForce G210M discrete graphics processor. Toggling between the GeForce G210M and GMA X4500MHD is as easy as switching between power plans, which can be done with the touch of a button located above the keyboard. The process isn't entirely seamless; the screen goes blank for a few seconds when you switch graphics modes. (http://techreport.com/articles.x/17939) I want to use linux or XP, but so can't enable G210, driver show me that the display is not connected to G210. May be we need to use some special util to swith GPUs.

This has happened before: the sony vaio z-series laptops also have had troubles informing the BIOS to switch on/off the discrete graphics card.
For the z-series, the solution was to dump and inspect the DSDT table, then call the appropriate method to switch on/off the card from the BIOS.

Unfortunately nobody has produced DSDT table dump yet, but it's very easy to do:

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.

Thanks!
