[gentoo-user] Tips for saving power needed...
Hi, admin of a colo-center keeps complaining my server is going a little over power-limit (which they have set as ~120W per 24h/avg, while my server needs ~130-135W). So I need to find a way to save at least those 15W, or I will be moved to higher tarif (which means higher costs for server-housing). Before going hard(ware) way, I would like to try first all possible software solutions. What I tried up to now is cpufreqd, CONFIG_NO_HZ=y, and spindown. In addition to that I adjusted fan-speeds to a little lower values and turned off some unneeded peripherials (in bios). Is there anything else I could do? Any tips would be greatly welcomed...

Any tips would be greatly > welcomed... Does you cpu support a technique like speed stepping? Then try setting the scaling governor to ondemand % modprobe acpi_cpufreq % echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor This may be working betten than using coufreqd? Or maybe you could lower the cpu and ram voltage in bios? But this can cause an unstable system.

If there is graphics hardware make sure the driver knows about power saving. An amd card on a virtual terminal needs as much power as an amd card in X doing heavy 3d lifting ... -- #163933

Well, I just spent an hour figuring out how to fix that problem :) I assume your HDMI card is "sink number 0" and the analog device is "sink number 1". That's how it works in my new machine, anyway. #grep sink /etc/pulse/client.conf default-sink = 1 I changed the 0 to 1 and now everything works normally. As for any kde app segfaulting.

I install the binary package from here: http://netbeans.org/downloads/index.html Running the installer as an ordinary user installs the whole thing in ~/NetBeans and it even updates itself if you want it to.

[gentoo-user] emacs - problem rendering pdf files
G'day, A few weeks ago I discovered that emacs is no longer rendering pdf files. Before, I could open a pdf file and read it using emacs, but no longer. When I open a pdf I get the following messages: ### message #1 ### in buffer that used to show the rendered pdf ### Welcome to DocView! If you see this buffer it means that the document you want to view is being converted to PNG and the conversion of the first page hasn't finished yet or `doc-view-conversion-refresh-interval' is set to nil. For now these keys are useful: `q' : Bury this buffer. Conversion will go on in background. `k' : Kill the conversion process and this buffer. `K' : Kill the conversion process.\n" ### message #2 ### in the emacs status bar ### DocView: process pdf/ps->>png changed status to exited anbormally with code 127 ### end of messages ### Research shows that both messages come from file /usr/share/emacs/23.4/lisp/doc-view.el. The first messsages is from function doc-view-buffer-message() and the second is from function doc-view-sentinel(proc event). Any suggestions of what's gone missing on my system ??? Thanks. David P.S. emacs is still rendering images (jpg, png, tiff, etc).

Most colo machines should do OK with just a text console running on the onboard GPU. Dump all video driver stuff "/dev/agpgart (AGP Support)" and "Direct Rendering Manager". This assumes you're not running X on your colo machines. mc (Midnight Commander) is a great text-based tool, along the lines of ye olde Norton Commander. * disable sound cards/chips in BIOS and remove drivers and kernel support. * Run "rc-update show" and look for any services you don't need. -- Walter Dnes
