afoard Posted July 19, 2016 Share Posted July 19, 2016 I am trying to passthrough a GPU to my linux guest. I am using Ubuntu 16.04 and my two GPUs are SAPPHIRE Radeon HD 6450 and SAPPHIRE R9 270. They have both produced similar results when testing one at a time. I am able to get output to display on my monitors and am able to see the Ubuntu splash screen, however the VM then boots to a black screen with a blinking cursor in the top left corner. I can type text and hit enter however nothing happens. At this same time I am able to SSH to the VM and login and run commands. This may be more of a guest driver issue but am looking for any suggestions. According to this page https://help.ubuntu.com/community/RadeonDriver both of my GPUs should be supported by this version of Ubuntu.

dudous Posted September 18, 2016 Share Posted September 18, 2016 Hi, i'm not an specialist but i am using and Radeon HD 6450 by XFX with Linux Mint 18 (that's based on ubuntu 16.04) and was able to passthrough by selecting Bios type SeaBios, assigning the Radeon card and choosing to install Mint in "Compatibility Mode". That did the trick for me. In fact i am not yet using the appropriate driver for that card (i was told that the old proprietary driver flgx was removed from ubuntu 16.04 and a newer driver is on the works) but the generic one that was installed is sufficient for me at the moment. If someone knows a better way, please let us know. Hope it helps. Quote Link to comment
