Hi, I have just upgraded my redhat box from a 7.0 (with lots of 7.1 and 7.2 rpm) to 7.2. I start X from the console using startx. I did it without problem just one time. Now I can only start X as root. As a user, I get: Fatal server error: PAM authentication failed, cannot start X server. Perhaps you do not have console ownership? I searched a bit on the web and I found my problem risen a lot of times, but I haven't found a solution. I also posted this question on other mailing lists (redhat-list and xfree86-list hosted by redhat) but I haven't have any solution yet. /dev/console is in mode 600 owned by root /var/run/console.lock is present in mode 600 owned by root /var/run/console contains a file with name the name of the user currently logged, owned by root with perms 600 the /etc/security/console.perms, /etc/pam.d/xserver are correct, and there is nobody logged in when the user log in. Any idea ? Pat
