Hi Ed, Here's a extract from an article about this matter: Source: http://blog.zorinaq.com/the-5-second-vga-dummy-plug/ It made sense for drivers to not enable a GPU when no monitor was attached to it. But since the rise of GPGPU applications, graphics vendors AMD and NVIDIA realized that this behavior was inconvenient. At least with the most recent Linux drivers, dummy plugs are not necessary anymore. So I wonder if the problem lies somewhere else.

If it is HDMI, maybe get a "dummy" plug to fake the system into thinking it has a monitor connected. https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=HDMI+dummy+plug Similar plugs are available for DVI. -- Fedora Users List - The place to go to get others to do the work for you _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
