Hello, I'm using woody. If I run xclock, all is fine. philippe@lapin:~$ xhost + access control disabled, clients can connect from any host philippe@lapin:~$ xclock -display localhost:0 Error: Can't open display: localhost:0 The error message appear after many seconds. Does someone know where X acces is forbidden ? Thanks, -- Philippe Ribet The README file said "Requires Windows 95, NT 4.0, or better." So... I installed it on Linux!
