Thanks for the posts! I took a look at that and then also found out some more stuff:http://www.vernalex.com/tools/services/?in...HotKey%20Poller
The ATI HotKey Poller is installed with any current ATI driver set. It is used in intercepting any key combinations that you define to perform specific tasks that involve multiple monitors. Simply put this means that this service listens to your keystrokes and when you press keys that match hotkeys that you define (macros) then it will perform the assigned task to that hotkey. If you disable this service then you will not have this functionality. I suggest most people should disable this service unless they use multiple monitors or odd output devices such as TVs.
Most current video cards support dual monitor display, and a few others support more (like the Matrox Parahelia that supports tri monitor display). This allows you to expand your computer's desktop across multiple monitors to give you more real estate. People that use their computers in more advanced ways, such as graphics design or those that just use a lot of programs at once, find this ability quite useful.
The ATI display driver is equipped to support the functionality of multi display. And this is where the Hotkey Poller comes in. Within the display property (right click desktop, properties) and under settings and then under the advanced button, ten under the Displays tab you have the ability to select which monitors or TVs to output your display signals onto. You can also configure hotkeys that perform tasks such as switching between multiple monitors.
If you wish to disable this service you should set it to disabled and reboot your computer as it will not let you stop the service. If you cannot reboot (or you don't want to) then you can kill the executable ati2evxx.exe. You can freely terminate (kill) these through task manager as they are not protected services. There will most likely be two of these processes running under the same name, but they're both the same thing. One is most likely a driver intercepter and the other a frontend client of sorts. If there are two then you will need to kill both to properly close them.
So while I could care less about the hotkey stuff, I do actually use multi-display (I just use my old lcd monitor above my laptop when I need a little bit more desktop space). But I'm unsure from what this stuff is saying as to whether or not turning off this process will have an effect on having the ability to use multi-display or just the ability to use hotkeys to switch between multiple monitors (which I don't do).
It also gives a possible explanation of why there are two processes running. (I turned off fast-user switching, and I still have two processes running. Not sure how to turn off the one running as USERNAME unless I were to kill it in task manager manually every time (which I don't want to do).
Any thoughts? http://www.tweakguides.com/ATICAT_4.html
ATI Hotkey Poller (ati2evxx.exe) - Also called the ATI External Event Utility, this service is primarily needed if you use the ATI Hotkey settings available in the ATI Catalyst Control Center. However, before disabling this service note the following: If you use a third party overclocking utility, you must disable this service otherwise the utility may not work; if you have an XT, X1000 or newer graphics card, disabling this service can also disable the OverDrive section in the Control Center, and can also prevent correct clock speeds being applied in 3D mode; if you run a laptop with an ATI graphics card, you may need to keep this service enabled to allow your LCD screen to switch off properly when the laptop is closed; if you use Fast User Switching then disabling this service may also cause problems with that. If none of the conditions above apply to you, I recommend that you disable this service.
I don't care about any of the 3D stuff as I don't do any computer gaming (and I'm going to turn off fast-user switching), but I am on a laptop, so the bit about the screen possibly not turning off properly if you disable this service causes some concern. Does this just mean if you close your laptop lid while the computer is still on, it may not turn off? Or that when you shutdown, the screen may not turn off? (I don't really ever leave the laptop on but close the screen, though I can see doing that if I were, say, at an airport and I had to hurry or something...) Thoughts?
Also, if I wanted to turn it off, would I go to msconfig, under the Services tab, just UNCHECK the ATI Hotkey Poller then reboot?
Could I always turn it back on, if I wanted to just test to see if it did effect the screen turning off when closing the lid, etc.?
Would I turn it back on the same way? Meaning, would it still be listed under the Services tab in msconfig, but just unchecked, and I could just check it again and reboot?
I also see that I have FIVE svchost.exe things running! Two for SYSTEM, two for NETWORK SERVICE, and one for LOCAL SERVICE. Why so many?
Let me know what you all think... Thanks!
