Hi

want to use Rockstor without display connected to it (headless) but receive this error message when no display connected to it.

Nov 9 21:25:31 rockstor kernel: [drm:radeon_vga_detect [radeon]] ERROR VGA-1: probed a monitor but no|invalid EDID

Nov 9 21:27:03 rockstor kernel: [drm:radeon_vga_detect [radeon]] ERROR VGA-1: probed a monitor but no|invalid EDID

is there a way to at least suppress these annoying messages

feedback appreciated

@AlphaLinux Hello again.
This is not Rockstor specific so I’d search on CentOS or RedHad and elements of that error message.

Hope that helps.

solved, by adding GRUB_CMDLINE_LINUX_DEFAULT=“nomodeset” to grub
