Using second GPU on notebook

Llorephie · 2015-10-02 16:21:27

Hi all, I've Lenovo B50-45 notebook with 2 videocards:

lspci -nn
00:01.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Mullins [Radeon R4/R5 Graphics] [1002:9851]
01:00.0 Display controller [0380]: Advanced Micro Devices, Inc. [AMD/ATI] Sun LE [Radeon HD 8550M / R5 M230] [1002:666f] (rev ff)

First - integrated, second - dedicated.

I want something similar to M$ W-'s Catalyst High Perfomance/Powersave option, where HP mode - second GPU, and PS - first.
But when I try to use something about (not match, tried it some time ago)

Section "Monitor"
    Identifier             "Monitor0"
EndSection

Section "Device"
    Identifier             "Screen0"
    Driver                 "radeon"
    BusID                  "PCI:0:1:0"
EndSection

Section "Device"
    Identifier             "Screen1"
    Driver                 "radeon"
    BusID                  "PCI:1:0:0"
EndSection

Section "Screen"
    Identifier             "Screen0"
    Device                 "Device1"
    Monitor                "Monitor0"
    DefaultDepth           24
    SubSection             "Display"
        Depth              24
        Modes              "1366x768_60.00"
    EndSubSection
EndSection

X faults with "no screens found".
XrandR says:

xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x84 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 3 associated providers: 0 name:radeon
Provider 1: id: 0x4f cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 0 outputs: 0 associated providers: 0 name:radeon

It's for open-source Radeon driver.
For fglrx so - it sees 2 videocards, but on choose second (1, 0 - integrated) X.Org segfaults on start (8)

And after last updates I got this on boot:
