Re: Debian Live Boot issue with Graphics Driver

[finlinux na <finlinux1973@gmail.com>]

Hello,

lb --version shows the following: 20220505

You are right...Only nomodeset was introduced since I was getting DRM error messages and it worked fine after introducing it.... rest options  "amd_iommu=off iommu=pt" were from the default GrUB template that I had set as I used to have  IOMMU error in other linux OS as well and OS used to hang as soon as it started video rendering.

On 2022-06-01 I've removed 'nomodeset' from the code, because that was
causing hangups during the boot of the 'failsafe' option.

Which version of live-build are you using?

Do you need all these 3 options for a normal live boot?
