<pre><span class="quote">> Interesting, that indeed that should work. Could be a bug in the VESA BIOS or the driver touching the hardware even if it decided not to do so.</span >

Adding to blacklist amdgpu not solve problem, but it pushed me to the idea of
doing the same thing with the intel driver.
And after adding i915.modeset=0 i915.blacklist=1 graphics subsusystem was
launched sucessful even with enabled IGPU in BIOS.
It seems that the intel driver is culprit here.</pre>
