xserver-xorg-core 1.19 in stretch does have the option to increase the client limit to 512, any chance of have this the default option? I only stumbled on this when I was looking for a different bug.
Section "ServerFlags" Option "MaxClients" "512" I also think this bug report should be closed now that it is fixed upstream and is in a Debian stable release. -- David Fries <da...@fries.net>
