Hi, I am new guy playing webos, following [VirtualBox Emulator User Guide](https://www.webosose.org/docs/tools/sdk/emulator/emulator-user-guide/), the boot success, login with ssh success, but graph UI launch failed, what ever pre-built images or self built. I check some log, found the following [7.780691] uvesafb: Oracle Corporation, Oracle VM VirtualBox VBE Adapter, Oracle VM VirtualBox Version 6.0.8, OEM: VirtualBox VESA BIOS, VBE v2.0 [7.833493] uvesafb: protected mode interface info at c000:4400 [7.834338] uvesafb: pmi: set display start = 0c5f393f, set palette = 3dcae7a4 [7.836004] uvesafb: pmi: ports = 1ce 1cf 1cf 1d0 3b6 3b7 [7.837231] uvesafb: no monitor limits have been set, default refresh rate will be used [7.839027] uvesafb: scrolling: ypan using protected mode interface, yres\_virtual=2400 [7.840854] uvesafb: cannot reserve video memory at 0xf0000000 [7.841959] uvesafb: probe of uvesafb.0 failed with error -5 [7.780691] uvesafb: Oracle Corporation, Oracle VM VirtualBox VBE Adapter, Oracle VM VirtualBox Version 6.0.8, OEM: VirtualBox VESA BIOS, VBE v2.0 [7.833493] uvesafb: protected mode interface info at c000:4400 [7.834338] uvesafb: pmi: set display start = 0c5f393f, set palette = 3dcae7a4 [7.836004] uvesafb: pmi: ports = 1ce 1cf 1cf 1d0 3b6 3b7 [7.837231] uvesafb: no monitor limits have been set, default refresh rate will be used [7.839027] uvesafb: scrolling: ypan using protected mode interface, yres\_virtual=2400 [7.840854] uvesafb: cannot reserve video memory at 0xf0000000 [7.841959] uvesafb: probe of uvesafb.0 failed with error -5 Dec 12 23:27:32 qemux86 systemd[1]: Failed to start webos - "surface-manager-daemon.service".
