Switch between two (different) graphics cards
Hi all,
I am on a fully-up-to-date Debian Sid.
My system is i7-8700k and, till now I've been using the "internal"
graphics card (served by i915 driver).
Now I installed a new (external) Radeon graphics card.
It is correctly seen by kernel:
00:02.0 VGA compatible controller [0300]: Intel Corporation UHD Graphics
630 (Desktop) [8086:3e92]
DeviceName: Onboard IGD
Subsystem: Gigabyte Technology Co., Ltd UHD Graphics 630 (Desktop)
[1458:d000]
Kernel driver in use: i915
--
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.
[AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X/590]
[1002:67df] (rev e7)
Subsystem: XFX Pine Group Inc. Ellesmere [Radeon RX
470/480/570/570X/580/580X/590] [1682:c580]
Kernel modules: amdgpu
01:00.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI]
Ellesmere HDMI Audio [Radeon RX 470/480 / 570/580/590] [1002:aaf0]
... but connecting a monitor to the new card I see no output and also
xrandr agrees:
mcon@cinderella:~$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x43 cap: 0xf, Source Output, Sink Output, Source
Offload, Sink Offload crtcs: 3 outputs: 1 associated providers: 0
name:modesetting
This is probably due to fact I need to start a second, different,
x-server for the second card.
Being able to switch between the two servers would be nice.
Can someone point me to the right documentation about how to do this?
