log of display mode changement
We have an ASUS X570ZD laptop equipped with AMD Ryzen 7 2700U with Radeon Vega
Mobile Gfx and NVIDIA GeForce GTX 1050 Mobile.
We tested it with Linux kernel 4.18.3. It is nouveau with parameters runpm=0
and noaccel=1 as the driver for NVIDIA GeForce GTX 1050 Mobile card.
After plugin the HDMI cable, the system is in extended mode and displays
correctly.
But the internal display becomes blank after changes to mirror mode, extended
mode and built-in only mode. The external display always works correctly.
There are the errors:
"[drm:hwss_edp_wait_for_hpd_ready [amdgpu]] *ERROR*
hwss_edp_wait_for_hpd_ready: wait timed out!"
"[drm:drm_dp_dpcd_access [drm_kms_helper]] Too many retries, giving up. First
error: -71"
in dmesg.</pre>
