I saw it in KDE and tested it afterwards in a konsole. I repeated as fast as possible the date program as following: andreas@athlon:~ > date Tue Dec 18 08:12:29 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:30 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:30 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:30 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:31 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:31 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:31 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:32 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:32 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:32 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:33 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:33 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:33 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:33 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:34 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:34 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:34 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:35 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:35 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:35 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:35 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:36 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:36 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:36 CET 2001 andreas@athlon:~ > date Tue Dec 18 09:24:11 CET 2001 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ andreas@athlon:~ > date Tue Dec 18 08:12:37 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:38 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:38 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:38 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:38 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:39 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:39 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:39 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:40 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:40 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:40 CET 2001 andreas@athlon:~ > date Tue Dec 18 09:24:15 CET 2001 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ andreas@athlon:~ > date Tue Dec 18 08:12:41 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:41 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:41 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:42 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:42 CET 2001 andreas@athlon:~ > date Tue Dec 18 08:12:42 CET 2001 This problem appears not directly after reboot but some time after reboot. The time when it appears after reboot is different. I can't say it's after 3 hours or 10 hours. It suddenly appears and doesn't disappear. I have to reboot the system to get rid of the problem. One effect of this problem is: The X-server begins to blink (the screen [not the monitor itself!] is going off and on again). Do you remember? I wrote the same problem ("blinking screen") some time ago - now, I probably found the reason. I couldn't reproduce this problem with none of the ac-patches!
