I recently bought a MSI GT72VR 6RD-280XFR notebook, which has a G-SYNC 120Hz display and a GTX 1060.
I have installed Ubuntu 16.04 and 381.22 nvidia drivers. All is working fine,except nvidia-settings does not show G-SYNC option. I think this is a limitation of nvidia linux drivers.
If you update the latest BIOS, please make sure you install NVIDIA graphics driver v368.83 or the newer version. 2. GT72VR starts supporting NVIDIA G-SYNC with BIOS version E1785IMS.10D. To support NVIDIA G-SYNC, please make sure you have updated that latest BIOS and NVIDIA graphics drvier on MSI website, and confirm that the build-in panel also supports G-SYNC. (The panel specification depends on the actual shipment)
I didnt know about what the last sentence is describing. So some GT72VR-6RD shipments have g-sync display, some other dont…
So I think you are right, to test if g-sync is working I have to install windows. Maybe this is not a driver issue but it is that the panel is not g-sync compliant.
I have some news from MSI forum, it was ambiguous if the panel of this notebook was G-SYNC compliant or not, well, finally it is not. So there is no nvidia drivers issue.
I will close this thread.
