I'm having periodic freezes of F18. The freezes happen when I click on a link. Usually this is in a Thunderbird window, but I've seen one freeze when clicking on a desktop icon. The system will work for a day or several days between freezes. When it freezes, the screen is frozen, mouse is unresponsive, and any sound which was playing repeats. I can ping the system, but SSH does not respond. The system logs show nothing. I recently upgraded the system from F15 using Nvidia drivers to F18 with nouveau driver. Power management is turned off. I've searched online and find some suggestion that there is a problem with X and the nouveau driver. Other suggestions about overheating or other hardware problems are unlikely. Any suggestions? -- Michael Eager eager@xxxxxxxxxxxx 1960 Park Blvd., Palo Alto, CA 94306 650-325-8077 -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
