A month or so back during updates from SUSE I started having problems. I am wondering if any of you are configured like I am and might have observed this bug. I am running SUSE 10.1. I also run the NVIDIA 8774 driver. I DO NOT see problems when only one person is logged on. However, two people use this machine such that one is on F7 and the other person is on F8. So switches to the two different environments happen multiple times a day. After about 5-12 hours one of the users starts seeing white tiny dots at the very top edge of their desktop. Within a few minutes (and especially if an F-key switch takes place) the keyboard stops working and the mouse and the screen goes away. (I need to describe what the screen looks like when it goes away but I can't at the moment). I can login with ssh from another machine and everything looks ok, except that "top" reports that X is using 100% of the resources. I usually do a reboot at that point and then the machine works again, usually for several hours. I have a gut feeling that this started when Xorg-x11-server-6.9.0-50.24.rpm was delivered via the software updater mechanism. I notice that Xorg now has version 7.1 available but I would prefer to try that via a SUSE delivery than to do it myself. If I prove that it is the X server I wonder how I can get SUSE to release the newer one? Questions: Is anyone out there configured to have two or more desktop users? Has anyone seen this behavior? Should I write the Xorg people? I know that I need to dig deeper and get more facts but was hopeful that someone might have seen this and solved it. Cheers, Bob
