Note 1: To get sound working add:

options snd-hda-intel model=ref

to /etc/modprobe.d/alsa-base.conf and restart.

Note 2: If you get a sudden decrease in internet speed, check for the existence of a proxy plugin in browsers, also try rebooting the switch in the hall if a hall computer.

Unused boxes - keep no more than half number of active systems plus one (e.g. three). Remove memory and video card when placing in storage.

Used in office

  • LG Flatron L1950SQ (19" TFT LCD 1280x1024@60Hz recommend 75Hz Max, 30-83kHz Horizontal, 56-75Hz Vertical). Ubuntu Nvidia driver when activated is only 640x480. Default driver does on 1024x768, this is due to the monitor, not the Video Card. See xrandr and monitor resolution, seems to be resolved by adjusting sync range in xorg.conf)

Spares

In general should only keep enough spares for three systems. If there are spares beyond this number and they are better than what is in systems they should be used rather than discarded.

Monitor

  • Dell 19" 4:3 DVI/VGA monitor with untested internal speaker
  • HP 17" 4:3 VGA monitor on IPEX AllStation X Base (stand available)

PCI Express Video Cards

  • Asus Dual DVI nVidia P345 (7600 GS? 512MB DDR2, 131 G3D)
  • Asus EN7300GS/HTD/256/M/A (60 G3D)
  • Nvidia X300SE HM 256MB (30 G3D)

Networking

  • Linksys WRT54G V2, unsure if working
  • Linksys WRT54G V7, needs power cycling monthly

Discard or Accept New Material?

The table below shows what to accept/reject. Enough material should be accepted until all hall computers, workroom (hot spare) and spares are held. Then raise qualification for Accept, move accept to hold and so on. In general to replace a computer and notice the difference, the passmark should be doubled
