I am trying to connect with mstsc to this machine (this is after fresh pc restart, noone has logged in):
while in this login box, no disconnect happens:
after I put there correct login/password, I get black screen first and then mstsc window closes. I tried to connect from KDE remote connection application, but it also failed same way. xrdp.log doesn’t seem to contain anything interesting:

How can I fix that?
原因分析
solved the issue myself, hopefully someone else will find it usefull. I took a look at ~/.xsession-errors, it contained:
(imsettings-check:16467): IMSettings-WARNING **: 04:42:56.491: Could not connect: Connection refused
(imsettings-check:16467): GLib-GIO-CRITICAL **: 04:42:56.491: g_dbus_proxy_call_sync_internal: assertion 'G_IS_DBUS_PROXY (proxy)' failed
GLib-GIO-Message: 04:42:56.807: Using the 'memory' GSettings backend. Your settings will not be saved or shared with other applications.
** (process:16260): WARNING **: 04:42:56.824: Could not make bus activated clients aware of XDG_CURRENT_DESKTOP=GNOME environment variable: Could not connect: Connection refused
and then I’ve googled a rootcause, miniconda installation has broken PATH in .bashrc file, I have removed this line and it has fixed it:
export PATH="/home/stiv/miniconda3/bin:$PATH"
UPDATE: Later I’ve found x2go, which works way more reliable and faster then XRDP.
解决方案
1、注释掉~/.bashrc中anaconda相关的环境变量设置
2、执行source ~/.bashrc
3、重启一个xshell连接，启动vnc
4、还原~/.bashrc中注释掉的anaconda相关的环境变量
5、执行source ~/.bashrc
