Re: Debian Live Boot issue with Graphics Driver

[finlinux na <finlinux1973@gmail.com>]

Hello,

And a quick observation.. My virt-manager loads isoconfig at boot time and while booting a laptop from CDROM, grubcfg is loaded...Is there any way to control which config can be loaded at boot time? Because virt-manager does not have issue with GPU drivers while hard booting Live from CDROM has issue with GPU drivers..

Hello,

Looks like Debian Live Distro needs the following option for kernel  in GRUB  config file if GPU driver is installed..

nomodeset amd_iommu=off iommu=pt

Else it will hang with series of DRM bit flip timeout error messages... Has anyone experienced this before?

with "nomodeset amd_iommu=off iommu=pt" I was able to circumvent the problem..But there should be a better way without disabling the GPU driver..

I am using Ryzen 3 machine...
