#2792 new defect

xpra shadow server "not working"

Reported by: stdedos Owned by: stdedos
Priority: minor Milestone: 4.1
Component: server Version: 3.0.x
Keywords: Cc:


Related to #2791?

While the client connects (and while #2791 is somewhat affecting), the client is opening the monitor windows, but it is effectively in a non-operational state.

Also related to #2617.

Logs, after filtered with | grep -viP "(New unix-domain connection received|on '[^']+xpra/user-ix-main-pc-0'|clipboard)", are very small and do not immediately reveal anything.

I did not have a chance to capture xpra-info before the server decided it was time to die.

I assume this is a regression?
A client regression?
Does it work with a Linux client? 4.0 client?
Can you post the client log?

Replying to Antoine Martin:

A client regression?

Idk, that is my guess

Does it work with a Linux client? 4.0 client?

This makes no sense to my workflow, and I don't have a system to test with that configuration. I also have been having #2617 - this could be the most recent/severe version of it (I also have used different client versions, so I decided to post a new bug, just to be sure).

Can you post the client log?

It's not clear to me if the bug is server-side or client side.
Did this go away when you downgraded to 4.0.x?

comment:4 Changed 7 days ago by stdedos

Now that I think of it, actually yeah. I managed to use 2/3 shadow monitors with ease (given the latency ofc)
