I have managed to get a solution for this issue by following the below
steps
Scenario 1:
1. Set intel to UXA mode and activate radeon DRI3 using the below xorg.conf
settings
2. Restart mdm by login out and loggin in again (I have experience very slow
rendering login page - Linux mint)
3. Issue command: DRI_PRIME=1 glxinfo|grep "OpenGL"( you will see the Radeon
renderer active)
4. Issue command: DRI_PRIME=1 cairo_dock& (cairo starts without problems)
PS: grub kernel were left its distro's default settings.
Section "Device"
Identifier "Radeon"
Driver "intel"
Option "AccelMethod" "UXA"
Option "SwapbuffersWait" "false"
Option "VSync" "false"
Option "DRI" "3"
EndSection
Section "Device"
Identifier "Radeon"
Driver "radeon"
Option "SwapbuffersWait" "false"
Option "TearFree" "false"
Option "DRI" "3"
EndSection
Scenario 2:
=======================
1. Set intel to SNA mode and activate radeon DRI3
2. Restart mdm by login out and loggin in again (screen rendering is fast)
3. Issue command: DRI_PRIME=1 glxinfo|grep "OpenGL"( I can only see the Intel
tenderer)
4. Issue command: DRI_PRIME=1 cairo_dock& (cairo starts without problems)
I hope this helps

Title:
Hybrid Graphics: [drm:si_resume [radeon]] *ERROR* si startup failed on
resume
Status in xorg package in Ubuntu:
Confirmed
Bug description:
dmesg shows issues with being able to use the discrete graphics card
(relevant dmesg lines attached).
Grub does pass "radeon.modeset=1" but it doesn't seem to make a
difference. If I pass both "radeon.modeset=1" and "radeon.startpm=1"to
the kernel, then it does not error (except for the VCE error -110,
which is probably harmless).
Running `DRI_PRIME=1 glxgears`:
- with "radeon.modeset=1" and "radeon.startpm=1", no error but only a black
window with a visible top bar.
- with just "radeon.modeset=1", error (attached as 'glxgears').
Results are similar on Ubuntu GNOME 16.04, except with
"radeon.modeset=1" and "radeon.startpm=1" set. It works, but lots of
screen tearing.
Attached are relevant dmesg lines, grep'd with 'drm'. I'll also be
attaching entire contents of dmesg, /var/log/syslog, etc., but TLDR:
