Description:
Xdummy crashes as soon as xpra connects.

I am trying Xpra on a kubuntu eoan (19.10) system. On this kind of system I have successfully used
xpra many times in the past. However, I am now encountering crashes that make it impossible to use it.
My system is a laptop with an intel i7-10510U cpu (comet lake) and integrated Intel HD graphics 620 (I believe).

For testing purposes I am attempting to use Xpra locally

xpra start :101
DISPLAY=:101 xterm &
xpra attach ssh:localhost:101

at this point, the xterm is briefly shown but xdummy crashes right after. Using --opengl=no does not seem to
make any difference.

Any hint?

Just noticed that the xpra bug-report tool spills out too much information to be pasted on a public forum, like here. User details like real name, public host name + user account.
Is there any way to permanently delete a ticket?

Description: modified (diff)
Owner: changed from Antoine Martin to callegar

I've removed the keyboard mapping and audio information since this is just a waste of space for an Xdummy related problem.

xpra start :101
DISPLAY=:101 xterm &

Always use: xpra start :101 --start=xterm instead.

Unless I can reproduce this bug on my test system, it is fair to assume that this problem is specific to your system.

at this point, the xterm is briefly shown but xdummy crashes right after.

Does the server crash? Or the client?

If the server, please run it with -d all and attach the server log.
If the client, please post the client output (also running it with -d all).
