Hi all,
I am the IT department here at my office, I take care of everything pretty much. I chose Centos4 to deploy to my 50 workstations as it was the most compatible with the RHEL. We need the RHEL compatibility for support contract for different tools we use. So far it has been great. I have noticed a few issues since having 50 machines all exactly the same installed with centos 4. I have them clustered, and generally they work well.
I often see random loss of the mouse cursor, which results in having to restart X. (really pisses the engineers off) I cannot seem to track down why this is happening. Nothing in any logs give any clue to what is happening. I thought it may have to do with VMware, as this is installed on 80% of these machines, and most of the time it happened when users were using Vmware. But recently I have seen the problem on machines without VMware running or even installed.
I have also noticed a similar issue with a Wacom tablet. The user will be using it for some amount of time and then it stops working. At first it is assigned /dev/input/event3, the kernel module (wacom.o) is loaded and everything is fine. It will then stop working after a while, behind the scenes the system thinks the tablet has been unplugged and replugged, then assigns it /dev/input/event4. This of course doesn't work because in the xorg.conf file it is looking for it at event3.
I am not sure if these are related or not. But the symptoms seem similar. Of course the wacom tablet is USB and the mouse issues are with PS/2 mice. So they may be unrelated.
Any help would be appreciated. Thanks for your time.
