Motherboard for both is from Gigabyte with Nvidia 430 chipset (MCP51). Chipset driver from Nvidia is installed (forcedeth has a problem with the built-in network card). It only happens in Gnome, I didn't try other window managers. When I type in the Terminal window or in gedit I basically cannot type a single word without at least one character getting repeated, sometimes several dozen of it in an instant, quite often each and every character gets repeated. Happens with every key, including ENTER. The only way I can prevent this is to type very slowly, say type a character, wait a second, type next character. But even then it can happen, but very seldom. Or I switch off key repetition. It's got nothing to do with the repeat rate or interval. It doesn't happen on the console or via ssh terminal. That's why I hoped installing the graphics driver from Nvidia as well might solve the problem. But it doesn't. Using the single CPU kernel fixes this it, so I think it's directly related to it and has nothing to do with chipset or so. There's another problem I encountered yesterday and first thought it's related to powernow-k8. With powernow-k8 system time runs too fast. This didn't seem to happen without it. However, now that I had it run over night without powernow the time has leaped almost an hour again, so it seems it happens without powernow as well. Could there be a connection? It seems that at least this issue is very common with the SMP kernel and there are several recommendations for kernel parameters, but I'm not sure which one to try first or what they exactly do: clock=pmtmr notsc noapictimer no_timer_check Kai -- Kai Schätzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com
