Sorry, I should have thought of that before. Checked output of 'ps ax' with a background job (ps ax | grep '/usr/bin/X ' > lt.out, repeated each second) during the lockup (timestamp of file 'lt.out' has been checked):
4088 tty7 R<s+ 3:40 /usr/bin/X vt7 -dpi 100 -nolisten tcp -auth /var/lib/xdm/authdir/authfiles/A:0-sJSBJL So the server is not sleeping. While not locked up, this line is, e.g.: 2980 tty7 S<s+ 0:01 /usr/bin/X vt7 -dpi 100 -nolisten tcp -auth /var/lib/xdm/authdir/authfiles/A:0-CWZXVL Regards, Olaf -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
