Hello,

I have an old Alienware m15 laptop with intel i915 graphic and nvidia RTX2080.

I installed Kali 2022 on it, everything is ok working perfect, both graphic cards are installed. for nvidia i followed the kali documentation to install it here

the problem is when i launch an app that requires nvidia, the app is using intel graphic instead, switching is not happening.

I have searched several solutions on google but so far im still stuck.

1/ i was supposed to find and option in nvidia setup to set nvidia to "prefered" but this option is not available in my nvidia panel.
2/ then i tried the DRI_PRIME=1 <my_app> and this did not work too
3/ then i tried to blacklist i915 and regen initramfs, this ended by making the laptop to fail booting, it seems to absolutely want to boot using intel graphic

4/ i tried to follow some youtuber solution :
Code:
xrandr--listproviders

Providers: number : 2 
Provider 0: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 5 associated providers: 1 name:mod
esetting 
Provider 1: id: 0x270 cap: 0x2, Sink Output crtcs: 4 outputs: 3 associated providers: 1 name:NVIDIA-G0

sudoxrandr--setprovideroffloadsink 0x270 0x46
 
X Error of failed request:  BadValue (integer parameter out of range for operation) 
  Major opcode of failed request:  140 (RANDR)

  Value in failed request:  0x270 
  Serial number of failed request:  16

Code:
lsmod|grep nvidia

drm
Code:
lspci|grep-i vga                                   
00:02.0 VGA compatible controller: Intel Corporation CoffeeLake-H GT2 [UHD Graphics 630] 
01:00.0 VGA compatible controller: NVIDIA Corporation TU104M [GeForce RTX 2080 Mobile] (rev a1)
so far i dont know what to do !

How can i desactivate the intel graphic and force the use of nvidia card ?

thank you for helping.
