I don't think it'll tell you if one of the voltage lines goes low under load or something. If it doesn't pass those tests, though, you'll know it's bad. Also, open the PS case and look for leaking capacitors. If you find any leakage, then you know you have a problem. I would just throw out the PS at that point, but you could probably replace the capacitors. -- Rich P.S.: I mean to post an update to my screen-blanking-while-watching-movies problem. I'll catch up with that later.

reboot problem

by Gregory Avedissian

At the meeting before last, I asked about a problem I'm having with the computer occasionally going to a black screen with no disk activity on reboot, right after the grub menu goes away. Overnight memtest showed no errors, I put a different vid card in, and still had the black screen problem. One of the things someone mentioned was to test the power supply. Recently, I had a few hard lockups and a couple of spontaneous reboots. So, how do I test my power supply, other than replacing it and seeing if the problem goes away? Or is that evidence enough to change it ASAP? According to lm-sensors, voltages are fine, and I've even sat and watched gkrellm for long periods of time - they look stable. Any suggestions would be appreciated. Greg

What about something with wireless technologies, I always hear complaints about wireless in Linux.

Looking for a project and contact person

by kstratton＠fastmail.us

I am looking for a good project to get involved with and I am looking for ideas. What I offer to the potential project: 1) Low level programming experience (no operating system) in C. I do know some assembly programming, but I would likely have to learn or relearn the architecture being used or developed for. I am currently developing non-trivial applications for microchip microcontrollers and I have also worked with MIPS4 (Microprocessor Without Interlocking Pipeline Stages). 2) Ability to read a datasheet and understanding of how hardware works. 3) Time Where I am weak (today): Although I consider myself to have basic linux/gentoo skills there is a plethora of linux topics and technologies that I need to learn in a more methodical way. I am willing to do my homework, but I looking for the focus or direction of a project to force me to learn these things. What I hope to achieve: Learn more about the interfaces to the kernel and other resources. I eventually wish to be reasonably independent developing for an embedded system. An example of a project that may be appropriate is lm_sensors, but at this time I am unwilling to continuously buy hardware to develop on. If anybody has any serious ideas, I am more than willing to listen. -- kstratton(a)fastmail.us

Depending on what software you use to watch movies... I'm fairly certain mplayer and gxine try do this by default, as I only recall having had the screensaver kick in while watching something in totem. -- Aaron Haviland

Ha ha! Guilty Gibson? Wasn't he a baseball player back in the '40s? Try changing the power settings in the BIOS. (Hit F2 while booting.)
