Lakka and Hybrid VGA: switch problem

Libretro Lakka
#1

Good morning,

I installed lakka on a i5 notebook with Geforce 610M / i950 intel hybrid graphics card.

While with Ubuntu and Windows I have no difficulty switching between the cards (and output/monitor), with Lakka none of the commands allow me the switch.

Lakka then only recognizes the i950 that has outstanding performance: PSP renders 1440x816 and output 1920x1088 when little 3d (otherwise renders to 960x544) instead with geforce (in Ubuntu) rendering and output to 1920x1088 !!!

How do I proceed?

This is my situation:

00: 02.0 VGA compatible controller: Intel Corporation’s 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01: 00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce 610M] (rev a1)

Thank you and excuse my English …

Hi,

Thank you.

Yes:

-sh: /sys/kernel/debug/vgaswitcheroo/switch: Permission denied

Ok, my error… sorry…

cat /sys/kernel/debug/vgaswitcheroo/switch 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :DynPwr:0000:01:00.0

I try with “echo DIS > /sys/kernel/debug/vgaswitcheroo/switch”, no reply…

“cat /sys/kernel/debug/vgaswitcheroo/switch” 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :DynPwr:0000:01:00.0

No difference…

The + indicates that the card is being used.

Try

 echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
 echo DIS > /sys/kernel/debug/vgaswitcheroo/switch

Also can you try to give the output of

for p in /sys/class/drm/*/status; do con=${p%/status}; echo -n "${con#*/card?-}: "; cat $p; done

Thank you.

This the out:

DP-1: disconnected HDMI-A-1: connected LVDS-1: connected VGA-1: disconnected VGA-2: connected

Thanks !!!
