--- Comment #3 from qwang13 <quanxian.wang at intel.com> ---
Update:
Checked this issue on WHLU01 with upstream kernel v4.19-rc5, this issue
reproduced.

When execute xrandr -s 640x360, the desktop would hang. But ssh still works
well.

root at WHLU01:~# cat /proc/cmdline 
BOOT_IMAGE=/boot/vmlinuz-4.19.0-rc5+
root=UUID=46ea8678-4edc-4015-8fea-f3f4449054d4 ro drm.debug=0xe quiet splash
vt.handoff=1
The dmesg logs include startup of OS (WHL-U_4.19_rc5_dmesg.log ) and issue
happened ( dmesg_640x360_4.19.0-rc5_WHLU01.log ) are attached.
