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.
I am looking for a good project to get involved with and I am looking
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
2) Ability to read a datasheet and understanding of how hardware works.
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
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.
Windows XP and OS X are both smart enough to not blank the screen or
invoke the screensaver when I'm watching a movie. My P4m-based laptop
(Dell Inspiron 8200) running debian etch blanks the screen after 15
minutes, even if I disable the screensaver and all power saving
options. I don't watch movies on it that often, so I resigned myself
to hitting the CTRL key every so often when I do. I installed Ubuntu
Guilty Gibson on my Opteron-based desktop (Asus A8V Deluxe
motherboard) yesterday and found it does exactly the same thing.
Do you have any ideas how I can get them to stop blanking the screen,
at least while I'm watching movies?

Our next WLUG meeting is approaching soon. On Wednesday, October 10th,
2007, we'll be having our Newbie Night at WLUG. On this occasion, new
Linux users are most welcome to attend and ask their questions to the
more experienced Linux users in a non-intimidating environment.
Experienced folks are also welcome to attend to help out the new users.
Try to remember what it was like when you were a new user and tailor
your answers accordingly! The new folks will be very appreciative.
Also, if some people would be willing to burn a few CDs or DVDs with
their favorite Linux distribution or Live CD, then the new users will
have choices that they can take home and try at their leisure. My
personal recommendations would be Knoppix, (K)ubuntu, OpenSuse, Damn
Small Linux, and some RedHat derivative (Fedora, CentOS, etc). Feel
free to share whatever your favorite may be. I also think that a few
laptops running these different distros would be great demo tools for
the new users.
One last note: unfortunately, I will not be present for this meeting.
I will be in Austin, TX on business. I've asked Chuck and Frank if they
would run the meeting. Just because I can't make it, you should all
still get together and enjoy the meeting. This is your chance to make
fun of me in my absence (as opposed to doing so in my presence!). :-)
I will have access to email during my trip.
Have fun, and remember, we were all new...once upon a time.
