The Switcheroo-Control is a D-Bus service to check the
availability of hybrid GPU configurations and integrate
with the desktop environment. This tool is the
recommended solution to manage GPU switching on systems
with multiple GPUs. <br>
<br>
Users are encouraged to move away from legacy tools like
prime, bbswitch, and bumblebee, as they can cause more
harm than good on modern systems. <br>
<br>
switcherooctl integrates well with Wayland and Xorg, is
a lightweight userspace utility and its functionality
extends across both Intel + NVIDIA and AMD + NVIDIA
setups. By using switcherooctl, users can easily select
which GPU to use for specific applications and eliminate
the need for complex scripts or environment variables.<br>

<br>
For openSUSE on SkyLake with Nvidia dGPU + integrated
Intel iGPU I followed this installation and setup guide
<br>
SDB:NVIDIA Switcheroo Control<br>

moz-do-not-send="true" class="moz-txt-link-freetext">https://en.opensuse.org/SDB:NVIDIA_Switcheroo_Control</a><br>
<br>
After installing the switcheroo-control package, it had
to be enabled as a service and then reboot:<br>
<font face="Courier New, Courier, monospace">
systemctl enable switcheroo-control.service</font><br>
<br>
-------<br>
<br>
According to its online help info<br>
<br>
switcherooctl version<br>
2.6<br>
<br>
switcherooctl help list<br>
Usage:<br>
switcherooctl list<br>
<br>
List the known GPUs.<br>
<br>
switcherooctl help launch<br>
Usage:<br>
switcherooctl launch [COMMAND…]<br>
<br>
Launch a command on a specific GPU.<br>
<br>
Options:<br>
-g, --gpu=GPU-ID The GPU to launch on<br>
<br>
The default GPU to launch on will be the first discrete
GPU, or the<br>
default GPU if there’s only one. Identifiers can be
found using the<br>
list command.<br>
<br>
------------<br>
Example:<br>
<br>
<font face="Courier New, Courier, monospace">switcherooctl
list<br>
<br>
Device: 0<br>
Name: Intel® HD Graphics 530<br>
Default: yes<br>
Environment: DRI_PRIME=pci-0000_00_02_0<br>
<br>
Device: 1<br>
Name: NVIDIA Corporation GM206 [GeForce GTX
960]<br>
Default: no<br>
Environment: __GLX_VENDOR_LIBRARY_NAME=nvidia
__NV_PRIME_RENDER_OFFLOAD=1
__VK_LAYER_NV_optimus=NVIDIA_only<br>
</font><br>

<br>
I have not so far any example command(s) to launch(?)<br>

Well, yes, I am there (also), and found the SDB document how to
enable the tool's service.<br>
<br>
I see I should not have added the question mark, as my post merely
was targeted as info about this generic Linux tool ;)<br>
One feature mentioned in the references is Selecting the GPU to use
when running a program from the desktop.<br>
