so on my laptop i have an apu and a dedicated gpu both amd i can use switcharoo just fine not that its a problem normally i just use DRI_PRIME=1 to run things with my dedicated gpu if needed. my question would i gain any benefit from using switcharoo to use my dedicated gpu all the time aside from more fps in firefox videos and not having to use the DRI command anymore. like is it safe? are there any security risks if so what kind? will it impact the life of my gpu and thus extend the life of my cpus integrated gpu? will it make my cpu run cooler leaving more headroom for my gpu? or will it require more headroom on my gpu taking away from games performance? and do muxless laptops just run the gpu all the time for display and what not?and will i gain fps in games like a muxeless laptop? i couldent find much info on my questions so any help thanks
Hi
On GNOME the dedicated GPU along with switcherooctl is already in the desktop. It adds a right click option to select and application that has a desktop file…
From my experience offload is good both from laptop (HP AMD APU/GPU) and desktop AMD GPU and Nvidia GPU…
There are a few tools around to set a profile for what the GPU(s) will do, or can be configured via command line to extend battery time/life etc.
I think it all depends on what things you are doing with either GPU on your system as this is, IMHO subjective and really up to you to test and see…
alright i will give it a shot andd see how it goes now is there any kind of added security risks doing this vs using my apu like will it be more easy for a “hacker” or anyone to determine anything about me or my computer by doing this or are the risks the same as just using my apu? for example i know that qubes os dose not allow any kind of dedicated gpu due to some kind of security risk. but i not sure if this applies to me considering ide be using an apu anyway if not my dedicated gpu and i dont think qubes os uses any gpu at all some other form of rendering display.
Hi
AFAIK they mostly relate to passing a GPU pass thorough (as in iommu and vfio-pci) and not related to offload…
Firefox doesn’t require powerful GPU. Webrender works with OpenGL 3.3.
You need special settings to use hardware acceleration for video and the newest FF.
AV1 hardware acceleration is not supported with Linux right now. So you may use GPU from APU and get less power consumption and less heat (if another GPU is switched off).
