Clipboard stops working after Reconnect

MoritzWeber0 commented 1 year ago

After reconnecting to a session, copy/paste doesn't work anymore.

Some potential workarounds are listed here: https://github.com/neutrinolabs/xrdp/issues/1188

Some notes / approaches I tried:

/var/run/xrdp/sockdir/xrdp_chansrv_socket_10 doesn't exist at all. Neither before the connection, during a working connection or after a connection (https://github.com/neutrinolabs/xrdp/issues/1188#issuecomment-924753999)
Setting a specific port (instead of -1) in the [Xorg] section of the xrdp.ini leads to connection freezes.
mkdir ~/thinclient_drives/.clipboard has no effect. (https://github.com/neutrinolabs/xrdp/issues/1188#issuecomment-926380372)
Setting different TCP keepalive times (/proc/sys/net/ipv4/tcp_keepalive_time) doesn't work in a non privileged context, so this is no option for us (https://github.com/neutrinolabs/xrdp/issues/1188#issuecomment-924079227)

The interesting log lines are:

[20221206-12:44:08] [ERROR] xrdp_mm_connect_chansrv: connect failed trying again...
[20221206-12:44:12] [ERROR] xrdp_mm_connect_chansrv: connect failed trying again...
[20221206-12:44:16] [ERROR] xrdp_mm_connect_chansrv: connect failed trying again...
[20221206-12:44:20] [ERROR] xrdp_mm_connect_chansrv: connect failed trying again...
[20221206-12:44:20] [ERROR] xrdp_mm_connect_chansrv: error in trans_connect chan

All in all, it seems that the cliprdr channel doesn't accept new connection after disconnect.

Manual restart of chansrv are not supported yet: https://github.com/neutrinolabs/xrdp/issues/1259

@MoritzWeber0 This issue is fixed with the upgrade to Debian Bookworm, right?
