Dell isn't very configurable on that score but try to turn off ACPI entirely. On the linux side, edit your XFree config file and (it will be XF86Config or XF86Config-4 in the directory /etc/X11/) so that Option "DPMS" "on" is Option "DPMS" "off" There is alpha quality ACPI support in the most recent kernels but no one is compiling it in to distros yet because it is such poor support at this time. This is what happens when a company (Intel in this case) makes its own standard and imposes it on the industry. The lag is much much longer than if the standard is developed openly. And a few probably did not want to answer because they care not to tell you that at least part of your problem is that it is a Dell. Dell uses its tremendous buying power to make its own tweaks on its systems, and I think you know with its very strong support of Microsoft that linux compatibility is pretty far from its primary objective, which, from my observation, seems to be cost savings in an extremely competitive and cost-sensitive market. And if, as it seems, you are using autofs, it might be wise to do a little search on www.mandrakeuser.org for why not to use it. Supermount works acceptably in 8.2.

Re: [expert] Miscellaneous 8.2 Terminal Hangs
What services are running? Are you running NIS? If so are you a client of a server? Also, are you running a firewall of any kind? Does the IP address on your machine match the name on your machine? (Do you call your machine monkey.foorbar.com but cannot do a dns lookup?) Also, how large is your log files? the delay might be the logging of a succesful login to files that take to long to append too...

Re: [expert] Miscellaneous 8.2 Terminal Hangs
I believe that all the users on my system (there are only a handful) use the default shell (bash) that would be set by using the useradd command. And as far as restricting the users that can login via ssh, well, I haven't used the "AllowUsers" keyword in sshd_config, if that is what you mean. Is any of that related to the problem that I've been experiencing? By the way, I've checked the system memory using memtest-x86 and came out with flying colors, so I guess that would most likely eminate that as a potential source of problems. ROB J.

Re: [expert] Miscellaneous 8.2 Terminal Hangs
bash and msec level = 3 If I remember, I'll try using a different shell to see if that makes a difference. Rob et wrote: >what shell are you using?
