I have an XPS 9575 with an i7-8705g and Vega M GL graphics. They were working fine until recently, where the Vega graphics have disappeared completely from my system. There is no driver for it, and when I try to manually install the driver, I get "...no AMD graphics hardware has been detected in your system configuration..."
Mind you, it was working fine for years. Instead, I only have the Intel HD graphics accessible.
Yea, that really doesn't make sense. The engine should be visible at all times. Have you checked BIOS Setup to see if there is a parameter that disables and hides this device? I have seen situations where the defaults for some parameters change with a BIOS update.
In Intel's implementation (the NUC NUC8i7HNK - which has the Core i7-8705G and Radeon RX Vega M GL graphics - and the NUC8i7HVK - which has the Core i7-8809G and Radeon RX Vega M GH graphics), the Intel HD Graphics 630 engine is not exposed (it is alive only to support transcoding, etc. type operations) and the Radeon engine directly owns all six connectors (2x HDMI, 2x DP and 2x USB-C). This allows the generic drivers to be used and thus upgrades don't cause any issues (barring the lack of support for later versions of the Radeon drivers). If your implementation has the two engines sharing the connectors (the way a lot of laptop designs do), then installing generic drivers (for either or both engines) could cause havoc - features not working, black screens, etc.
Hhmmm... Have you tried doing a from-scratch uninstall? Try this process:
Hope this helps - and let us know what happens,
Thank you for posting on the Intel️® communities.
After checking the information provided and the steps that you tried, it is better for you to contact the laptop manufacturer.
