Hi, I am investigating an issue where we lose video activity when the display is switched from from “text mode” to “graphic mode” on a number of servers using this driver. Specifically starting the GNOME desktop. This adapter is Server Engines Integrated Remote Video Acceleration Subsystem (RVAS) and is used as remote console in iLO/DRAC environments. I don’t see any specific errors in the gdm logs or message file other than this: mgag200 0000:04:00.0: remove_conflicting_pci_framebuffers: bar 0: 0x9b000000 -> 0x9bffffff mgag200 0000:04:00.0: remove_conflicting_pci_framebuffers: bar 1: 0x9c810000 -> 0x9c813fff mgag200 0000:04:00.0: remove_conflicting_pci_framebuffers: bar 2: 0x9c000000 -> 0x9c7fffff fb0: switching to mgag200drmfb from EFI VGA mgag200 0000:04:00.0: vgaarb: deactivate vga console fbcon: mgag200drmfb (fb0) is primary device mgag200 0000:04:00.0: fb0: mgag200drmfb frame buffer device [drm] Initialized mgag200 1.0.0 20110418 for 0000:04:00.0 on minor 0 The systems worked fine with 4.18 kernels and a recent Linux 5.2.18 ; The symptom first appears in 5.3.6. and onward. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
