Hi, folks.
My current vdr is instaled over "normal" ubuntu desktop since forever. Now I want to try something similar starting with ubuntu server and reducing installed packages to the minimum.
I found a similar ideia at this link: http://kuparinen.org/martti/comp/vdr/vdr.html
Now for the questions:
- Anyone with similar approach? - What is the minimum xorg needed? - Recommended settings?
The ideia is to have a lightweight system installed on a usb pen (almost all files are read only, so no problem) and add one or more HDD drives to perform the recording. Those drivers will only work when a recording is scheduled. Thus reducing noise to the minimum. Currently I have almost no dB coming from my vdr box, except for the disks.
I need to take in account other applications xorg needs. Like xine, mplyer, whatever.
I really want to end up with a minimal/no noise fully working system.
Thanks.

I used to do this with a usb flashdrive but have switched to CompactFlash connected with a CF->SATA controller. Also only have one drive in the box for recording (which I'll move to my fileserver eventually). For the harddrive I just set a spindown timeout so it goes to sleep when not in use.

I run "minimal" diskless ubuntu setups on a vdr server and three clients. The basic "cli" install of ubuntu desktop is <600MB and on the server there's not very much to add, just what's needed to compile vdr and an nfs server. On the clients I just install xinit and xorg-driver plus what's needed to compile xine. Then I start X with startx and vdr-sxfe/xbmc/performous with the remote using .xinitrc/irexec. No gdm or window manager, except for on my desktop client. And with a picoPSU the clients run at <30W so they're silent all right. The server with three hdd's and raid5 use a bit more but it's hidden away in the attic so I can't hear it anyway. I usually start by installing the latest version of ubuntu on one computer and then duplicate that directory for every client. Then it's just to boot that install for every client and add the rest of the packages needed for that hardware (I have one intel, one nvidia and one amd client so I can follow their respective X driver progress). /Magnus H

Completely diskless clients booting through PXE or iSCSI from single image or from dedicated images from server are also worth to try. This work fast on gigabit networks with dedicated network cards on server per client. Haven't tried this with VDR yet, planning in future.

That's what I meant. I have diskless clients booting through PXE from dedicated images. And I just have a single 100Mb interface to serve four clients but that more than enough. /Magnus H

100Mbps EPIA EK8000 server here, with 2 diskless/deviceless clients. According to Munin, during a typical week : * peak disk IO : 2k blocks read per second, 2k blocks written per second * peak eth0 traffic : 10Mbps to the server, 15Mbps from the server * 2% CPU due to the VDR server process * 8% peak CPU due to DVB + eth devices during recordings or live-view * 80MB memory for all userland apps (VDR + Samba + DNS + MPD, etc. etc.)

Ubuntu desktop under <600MB? My standard Ubuntu install uses more than 1Gb.
Do you have a non standard install procedure?
