Hello, I wanted to disable CSM on my computer (asrock extreme 6)
I got host graphics using intel card (0.02), vm graphics using r9 290 (01) and i want to be able to have another card (02) (actually a old HD 5870, if it work a nice 4k ready nvidia card) But, when i disable CSM, the computer doesn't manage to start X: On screen the log says and stay block at last line: Mar 12 14:54:34 lindesk kernel: vgaarb: setting as boot device: PCI:0000:00:02.0 Mar 12 14:54:34 lindesk kernel: vgaarb: device added: PCI:0000:00:02.0,decodes=io+mem,owns=io+mem,locks=none Mar 12 14:54:34 lindesk kernel: vgaarb: device added: PCI:0000:01:00.0,decodes=io+mem,owns=none,locks=none Mar 12 14:54:34 lindesk kernel: vgaarb: device added: PCI:0000:02:00.0,decodes=io+mem,owns=none,locks=none Mar 12 14:54:34 lindesk kernel: vgaarb: loaded Mar 12 14:54:34 lindesk kernel: vgaarb: bridge control possible 0000:02:00.0 Mar 12 14:54:34 lindesk kernel: vgaarb: overriding boot device: PCI:0000:01:00.0 Mar 12 14:54:34 lindesk kernel: vgaarb: bridge control possible 0000:01:00.0 Mar 12 14:54:34 lindesk kernel: vgaarb: no bridge control possible 0000:00:02.0 Mar 12 14:54:34 lindesk kernel: vgaarb: device changed decodes: PCI:0000:01:00.0,olddecodes=io+mem,decodes=none:owns=none however, as the pc boot fine (but without video), threw ssh i know that after these lines are printed: Mar 12 14:54:35 lindesk kernel: snd_hda_intel 0000:02:00.1: Handle vga_switcheroo audio client Mar 12 14:54:35 lindesk kernel: vgaarb: device changed decodes: PCI:0000:01:00.0,olddecodes=none,decodes=none:owns=none Mar 12 14:54:35 lindesk kernel: vgaarb: device changed decodes: PCI:0000:00:02.0,olddecodes=io+mem,decodes=none:owns=io+mem I think that, at boot, intel card is used, bios, grub and start of boot. Then the kernel tries to use the r9 290 card on slot 01:00.0 as default vga card And only after the disable_vga boot parameter is used to disable the same card... Right now, without CSM, pc doesn't boot graphics What i want: host on intel and vm using r9. Does someone have any clue? Why does a uefi ready card try to get vga? -- Deldycke Quentin
