Hi everyone, I recently got an ASUS KGPE-D16 mainboard, since I read over here, that it would be fully compatible with Qubes OS. Installation went fine, the only problem is the low screen resolution (VGA). Unfortunately, I can't get any external graphic cards to work.
As soon as I connect my graphic card to the mainboard (AMD Radeon 6450), the boot process halts shortly after I enter my LUKS password. After entering my password, the boot screen switches back from graphics into text mode (black/white) with the following error message: ERST: Failed to get Error Log Address Range. BERT: Can't request iomem region <00000000ccffa....................................> _ And that's it.. Nothing happening from that point on. I can only reboot / force shutdown. Overall, what I find weird as well, is that it takes much longer for the screen to get a video signal when the external GPU is plugged in. When I use the onboard VGA graphics, the screen reacts / shows the boot screen already a few seconds after booting compared to 30-40 seconds with external GPU ?? Any idea how to fix that as well ? Important notes: I upgraded the kernel in dom0 to the latest version. Although I didn't try any GPU with the old Kernel (4.4), thus I don't know if the issues are also present with the older kernel. Does anyone know ? I thought upgrading kernel would always increase hardware support. I also tried to boot with a NVIDIA 980 GTX graphics card, I had exactly the same boot issue. So I guess it's nothing related to any NVIDIA/AMD driver issues. Motherboard: ASUS KGPE-D16 GPU: AMD Radeon 6450 dom0 Kernel: 4.9.56-21 Thanks you for help! So far I tried to use 2 different graphics cards, first a NVIDIA 980 GTX and then an AMD Radeon 6450. The Radeon card is supposedly fully supported according to the Qubes and Xen Wiki's. The problem is exactly the same for both cards, so I don't really believe it is an AMD/NVIDIA driver issue. But maybe I am wrong ? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
