When you write "application dimmed", do you mean the whole desktop<br> darkens, or only some windows go black and white?<br> When it happens, if you type control-alt-F1, log in with your usual<br> user name and type "top", can you see which process goes through the<br>
roof?<br> </div><div><div></div><div><br> Vincent<br> <br> The dimming just occured while I was running FF, update manager and xsensor. Everything dimmed. I am not sure that it is always the case that everything dims. Did control-alt-F1 then top, FF was taking maybe 7-9%, Update from 7-60%, and another program maybe 5-7%. Maybe FF jumped once or twice. But nothing really took over. The screen undimmed of its own accord, so this was not one of the those times where anything froze.</div>
</div></blockquote><div><br>gary </div></div></blockquote><div><br>I can add a bit more info. Screen refresh had become very sluggish. With FF running without sound or video and Skype the same, Pulse Audio was taking 20% of the CPU, FF froze after I checked cpu usage. <br>
<br>Everything was fine after I rebooted.<br></div></div></blockquote><div><br></div></div></div>By any chance, did you happen to be on a site that uses Flash when FF froze up on you? I don't know what the cause is, but I have had other computers where FF froze up while on a Flash-enabled (which is an oxymoron IMO, but I digress) site. By FF freezing, I mean it winds up sucking up all available CPU cycles and memory to the point where the system becomes unusable. Again, never figured out the cause, but the problem eventually just mysteriously went away for me at some point.</div>

I am having a problem at the moment, characterized not by dimming (which often accompanies this problem) but by a typing lag, slowness in scrolling and switching between tabs and programs, etc.<br>
