Package: xserver-xorg-core
Version: 2:1.7.7-2
Severity: normal
It's 2010, and we still can't open more than about 194 clients (My
ulimit is for 1024 open fds). Meanwhile, it is clear that the
tradeoff that was made to only allow 256 connections is heavily
lopsided towards allowing those clients to open far more resources
than any actually use in practice.
https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/260138
Large clients have been shown to use 3500 resources each, but we allow
them to use 2^29/256, or 2 million. Can't we steal quite a few more
bits for increasing the number of X clients?
People have done this before:
https://bugs.freedesktop.org/show_bug.cgi?id=9209
http://readlist.com/lists/lists.freedesktop.org/xorg/3/17055.html
http://old.nabble.com/Maximum-Number-of-Clients-td7307396.html
If it's a bit too much work to add a configuration or cmdline option,
can't we change the default anyway, since it's already so heavily
lopsided?
