Hi all
i am working on passthrough my IGD to a vm,and it's well down with the win10 VM guest except freezing sometime.
when i change the VM guest to Ubuntu 21.10 ,i can only boot with nomodeset ,so i cannt use the GPU's full power.
my ultral target is to run NAS + BlissOS on the PVE system.
i need to fix the driver problem first to run my ubuntu OS without nomodeset
i has been checked all of the infos about IGD passthtough,but still cant fix it.
Could someone help me!!
