I used ‘buildiso -p xfce’ to make my own Manjaro build. It works ok on my PC and it works well on a virtual machine (VirtualBox).
But when I try to start it on my laptop, it doesn’t start (“Welcome to Manjaro”, then black screen).
On my basic PC there is an Nvidia card. On the laptop - some sort of radeon.
I added the following lines into the Packages-Desktop:
The oem profile is intended for system vendors as it differs in that it does not do a complete setup - but leaves the user-setup to be done by the final user.
The default profiles are those used by Manjaro Team when new ISOs are released.
So if the ISO boots on one machine but not another, everything point to the hardware in question.
I know it is not want you want to hear but it seems impossible to provide a meaningful suggestion on how to solve the issue.
