Hi;

I also got that error with CCL.

I did a couple of things (maybe not all of which were necessary):

Told my FC25 display manager (SDDM, notably neither GDM nor KDM) to add the following to the invocation of the X-Server "-listen tcp" (this was not required for SBCL to work - perhaps it goes via a unix domain socket rather than a TCP/network socket?), and rebooted, but no joy, so I
disabled x11 authorization via "xhost +" (maybe Phillipe's suggestion would have worked after I did the other things in this list, but his suggestion was the first thing I tried, before all these other things, and it didn't seem to do the trick), but still no joy, so I
upgraded CCL from 1.10 to 1.11, and
installed the latest CLX into local-projects, and for good measure
cleaned up my cache of FASLs

During the process, and even testing with Xnest, I variously got "protocol version mismatch" errors, hangs in response (apparently waiting for X11), errors opening the display, and a regression from CCL where it seemed to not like :accessors in application-frame environment variables.

Finally, I got the following to work:

lx86cl64 --eval '(ql:quickload :clx/demo)' --eval '(xlib-demo/demos:demo)'

Then the ql-gui worked. I am not sure exactly which combination of things did the trick. I can try and be more careful when I redo these fixes on my other development box.

Hi,

If this has not been answered already, I think you have to enable localhost access for X:

xhost local:local
