Switch graphics card via Wine?

[r3son]

Hi,

I have a PC with two graphic cards one Intel onboard and one Nvidia dedicated card. lspci shows me both and both graphics drivers are installed.

Code: Select all

> lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
01:00.0 VGA compatible controller: nVidia Corporation G98 [GeForce 9300M GS] (rev a1)

wine.log shows me:

Code: Select all

trace:wgl:wglGetProcAddress func: 'glAccum'
trace:wgl:X11DRV_WineGL_InitOpenglInfo GL version             : 2.1 Mesa 7.10.2.

I think, Wine only uses the slow Intel card. Is it possible to force Wine to use the NV card instead and how?

Wine will detect and use the card that is in slot 0 first. In this case the Intel card will be detected and used (this is not a Wine feature, it is a feature of Linux.) The only sure method is to swap which card is detected first or to completely disable the Intel card if possible.

Thing why I'm also asking for this is, that the hybrid-graphics switchers like 'bumblebee' make it possible to use both graphics cards the same time.

I guess, that there must be an option to switch the right card via Wine. If this is the case, maybe someone with more Wine experience can open a feature request or bugreport for this?!

Or, have I misunderstood something?

r3son new idea. Not enough developers have the hardware.

Yes it brings some new and interesting problems.

Wine does not rule hardware. X11 does and its backing drivers do.

Applications are told what features video card supports. Problem is some applications install those settings in registry and not check the card again.
We need items like bumblebee to support auto activation.

Auto activation wine uses a feature if the intel cannot do it wake the Nvidia up. Infact the user running wine may not have the right to switch a video card on and off.

Sorry to say r3son items like bumblebee are not developed far enough to be used effectively with wine yet. The key feature of auto activation is missing.

All video card control is not Wine issue basically. Its a X11 configure and driver issue.

Ok,
so we have to wait for further developments.

Thanks for your explanation.
