Alan, I took the window manager out of the equation by running multiple<br>
instances of vkcube with Xorg without running any window manager.<br>
Xorg.0.log file does show a log about set max clients through a .conf file:<br>
(**) Option "MaxClients" "512"<br>
<br>
But, I start seeing below error messages at the end of the log file once<br>
the number of vkcube instances go past 256:<br>
"_XSERVTransSocketUNIXAccept: accept() failed"<br>
<br>
Seems like the modified max clients limit of 512 is not getting configured<br>
correctly in X.<br>
<br>
What can I do to fix / debug this error ?<br>
