Nvidia Optimus Samsung RF711

Hello

This laptop has hybrid graphics.

Code:

00:02.0 VGA compatible controller: Intel Corporation Device 0116 (rev 09)

01:00.0 3D controller: nVidia Corporation Device 0df4 (rev a1)

Recently NVIDIA released driver that can support my card (GT 540M)
Unfortunately by default intel graphics card is always selected.

So NVIDIA proprietary driver installation ends up with error

some relevant xorg.log portion

Code:

(--) PCI:*(0:0:2:0) 8086:0116:144d:c0a5 rev 9, Mem @ 0xf5400000/4194304, 0xc0000000/268435456, I/O @ 0x0000e000/64

as you see above intel is primary. Xorg.log shows it with *. So nvdia card is abandoned. I have no option at BIOS level to set nvidia as primary. Can someone help me to force system to use nvidia card as primary graphics?

Many thanks in advance

Sorry, but today, the Linux support for NVidia Optimus is just ZERO percent.

Try the new asus-switcheroo project by AWilliam

I had to do my homework before buying my new laptop. I'm still a fan of Nvidia's GPUs, and I wanted one in my new laptop, but it was tough to find an option without Optimus.

I ended up with a Dell XPS 17 L702X, with an i7, GeForce GT 550M 1 GB video, and the 3D 1080p screen. The 3D option disabled Optimus support. My laptop is a desktop replacement, so I don't care too much about battery life anyhow.

So far, this laptop is sweet...

To use asus-switcheroo I need to have _DSM, MXMX & MXDS methodd. After extracting DSDT I see so i miss MXMX/ MXDS methods. So seems this switchero is useless.
I am really glad so some of you bought laptop without Optimus.

Still my questions remains unaswered: I need only one thing

how to disable completely intel graphics? Or is there any way so my NVIDIA graphics becomes 00:02:0.

Code:

00:02.0 VGA compatible controller: Intel Corporation Device 0116 (rev 09)

01:00.0 3D controller: nVidia Corporation Device 0df4 (rev a1)

if you can't do it by bios or by switcheroo, at today, for what I know, you can't: blame Nvidia.

I am probably wrong, but isn't Optimus needed when you need to on-the-fly switch between the two cards ?

Since tikcop1 just wants to use the nvidia card, won't putting the following in the Device section of xorg.conf work ?

Code:

Driver  "nvidia"

BusID    "PCI:1:0:0"

Or does the BIOS disable the second card altogether and only the primary card is alive ?

On Optimus laptops, the intel GPU is always enabled till 3D acceleration is needed, at which point the nvidia card is triggered and sends it's output over the PCIe bus to the integrated GPU. Unless there is a BIOS switch (which means it's not really Optimus in the first place), it is not possible to use the nvidia driver at the moment. Period.

I have no option in BIOS to switch it off.

Can I replace it with any other BIOS to get possibility to switch off Optimus?

My laptop is a kind of desktop so I really don't care at this moment for battery.

no, because if you don't have the bios option it means the display is hardwired to the intel board, so no way.

as I said in my previous message you should better ask for support to nvidia/samsung people, I think this has nothing to do with slackware.

You want a brick? Stay away from this jokes! :D

A laptop is very difficult to be modded as BIOS. Just stay away. ;)
