Users / Slow Samba Transfers
« on: January 02, 2010, 05:27:52 pm »
I'm getting about 1MB/s transfer via Samba from my CORE to my windows client PCs over gigabit ethernet. Via FTP I get ~ 10MB/s.

Anyone know why Samba is so slow and what can be done to improve its transfer speed? I'm using a clean Beta2 DVD install with all the updates.



Users / OrbiterInstaller.msi is 0 bytes
« on: December 18, 2009, 04:18:51 pm »
Windows executables were returned during the alpha (pluto-orbiterinstaller (363) - Windows orbiter executables are available again) but with the latest beta they seem to be missing again.

Can someone send me the latest orbiterinstaller.msi?

PM me if you have it and I'll give you my email addy.



Installation issues / SOLVED: AVWizard resolution problem
« on: October 12, 2009, 07:47:25 am »
Having been through multiple installations, different BIOS versions, nvidia driver versions, and having crossed my fingers a few too many times, I've finally had a breakthrough on the issue of getting past AVWizard.

Problem I was having was as follows: AVWizard gives blank screen regardless of selected output connection  (1,Q,2,M,3,4,5) and resolution (6,7,8,9,0)

I went through AVWizard blind and took a look at Xorg.0.log. It was reporting "no requested modes" and reverting to "nvidia-auto-detect" 1024x768, and my display was having none of it. Even though AVWizard set the correct "1920x1080" modeline in the monitor section of xorg.conf, X server wasn't trying to use it apparently. Issue was solved by adding the following to the Screen Section:

Subsection "Device"
Modes "1920x1080"

Installation issues / M3N78-EM Video Issues
« on: October 08, 2009, 04:20:55 pm »
Hardware setup:

M3N78-EM Motherboard w/ Brisbane Processor (onboard nvidia 8300)
1080p 60Hz Panasonic Plasma TV (TH-50PF11UK)

I've been having trouble with very sluggish UI2 (no alpha blending) and very bad tearing in 810 with my installation on this hardware. OpenGL performance seems to be all around terrible. I have tried many different driver versions from 177 to 185.

I believe the issue is not caused by LinuxMCE. I am posting here regardless because I know there are a number of users who have the same motherboard and I am appealing to those people for help.

Why do I think the issue is independent of Linuxmce?

I decided to reinstall Kubuntu 810 and evaluate video performance BEFORE installing linuxmce.

Independant of nvidia driver version, VGA, DVI, or HDMI port: Glxgears run in a maximized window with VSync turned off is giving 45fps, stutters and tears horribly. Turning vsync on, the framerate drops to below 25 and the test looks even worse. I did this same test a while ago with an 8500GT PCIE installed on the same mobo and got framerates closer to 600 to 700 with no VSync. Everything worked wonderfully with this PCIE card.

Questions for M3N78-EM users who have working setups:

Below is the last few lines from "cat /proc/interrupts"

Code: [Select]
16:         56      13942   IO-APIC-fasteoi   eth1
 17:          0          2   IO-APIC-fasteoi   ohci1394
 20:        232     377198   IO-APIC-fasteoi   ehci_hcd:usb4, nvidia
 21:          0        309   IO-APIC-fasteoi   ehci_hcd:usb3, HDA Intel
 22:          1        272   IO-APIC-fasteoi   ohci_hcd:usb2
 23:          3       8813   IO-APIC-fasteoi   ohci_hcd:usb1
219:       1572     633093   PCI-MSI-edge      eth0
220:         87      67450   PCI-MSI-edge      ahci

Does this look different from yours? Has anyone managed to get nvidia on its own interrupt through some bios settings?

How does your glxgears performance compare to mine?

Could video performance be compromised if the card is not running at a precisely standard resolution / modeline timing?

I found the following in my Xorg.0.log:

Code: [Select]
(==) NVIDIA(0): No modes were requested; the default mode "nvidia-auto-select"
(==) NVIDIA(0):     will be used as the requested mode.
(==) NVIDIA(0):
(II) NVIDIA(0): Validated modes:
(II) NVIDIA(0):     "nvidia-auto-select"
(II) NVIDIA(0): Virtual screen size determined to be 1920 x 1080

It seems the plasma TV is not communicating EDID information properly as I recall usually seeing mode validation performed in this section of the log. Could this be related somehow?

Anyone have any idea what could be wrong with my setup?

Thanks in advance.

EDIT: Fixed CPU type

Users / Alpha 10 installer
« on: October 05, 2009, 05:04:54 pm »
Just completed a reinstall on my hybrid M3N78-EM, using onboard nvidia video card and found two issues:

1) AVWizard would not display correctly after rebooting. Visible on the top left hand side of the screen was a short green bar, about half the width of the screen. Moving the mouse to the top left side of the screen the mouse pointer would become visible, but vanish anywhere else. I tried pressing 1 through 4, as well as Q and S... same result for each.

(I manually downloaded and installed nvidia drivers and all is now well)

2) The post-reboot iptables issue which I thought was a result of my previously botched install has persisted through this reinstall. Firewall disable/enable workaround still works.

Still going through testing and will report on anything else I find.

Users / Cover art won't go away
« on: September 23, 2009, 01:29:00 am »
I used the import-attributes-from-amazon feature a while back, and somehow due to my screwing with things alot of my cover art got assigned to the wrong mp3s. Due to the large amount of incorrectly assigned art, I've decided I want to start again with assigning cover art.

I've done the following:

1) moved all my mp3s out of the /home/public/data/audio directory into a temporary directory.
2) cleared the pluto_media table as instructed in
3) deleted all .id3 files from the temporary directory
4) deleted all files contained in /home/mediapics and /home/coverartscan
5) using mediamonkey tagging software, removed all album art from all mp3s in the temporary directory
6) moved mp3s back into /home/public/data/audio
7) ran resynchronize media from the web admin

Here is a sample of the output:

The album art returns. It seems to have stored somewhere other than the locations I've been clearing. Can someone explain how to thoroughly cleanse my library, short of doing a reinstall? I'm out of ideas.

Users / improvements

There are a few grammar and spelling errors that take away from the professional look and feel of the page. I'd like to suggest a few corrections, to whom can I send them?

Users / DIM level mappings
« on: September 09, 2009, 09:47:52 pm »
I have a couple ACT Homepro lamp modules and I noticed that the brightness level mappings are not ideal. For example, changing from 90% to 100% there is almost no perceptible difference. The same goes for 70% to 90%. There is a big difference in perceived levels below this however.

How can I re-map these intervals so that I have higher resolution? Is this problem likely specific to this model of controller? Can I create a mapping for each individual device or are the mappings global?




Users / Poor Call Quality
« on: September 09, 2009, 04:13:22 pm »
I'm experiencing poor (tinny-sounding) VOIP call quality. Internal calls suffer the same problem, so I've ruled out my VSP as the cause. The problem is also independent of softphone client and choice of protocol (IAX/SIP).  Any ideas what the culprit could be?

Could this be related to the fact that my home network is completely wireless after the core?

Users / Streaming via PPTP to iphone or PC
« on: September 07, 2009, 06:56:33 pm »
Thanks to donpaul for his work in bringing VPN to linuxmce. I'm excited about streaming video from the core to an external pc or my iphone using this.

I typically get 50kb/s from my core to another consumer quality point of access over the VPN. This is not enough to stream most of video material in my library, from my initial tests. I assume there are ways to compress the video in realtime and stream it at a lower bitrate so that I don't need to create lower quality copies of all my material just for remote viewing.

Where can I learn more about implementing something like this? I read up a bit on mediatomb, and I get the impression it can do this. I'd like to know what I need in the way of a client (on a PC or iphone) and what configuration needs to happen on the two ends.



Users / iphone (SIAX client) and asterisk
« on: August 27, 2009, 05:00:14 am »
I'm using SIAX on my iphone as an extension in linuxmce and am experiencing a strange situation.

When using the iphone over wifi (connected to internal linuxmce network) I must use as the host name to register. If I use the internet IP address of my core, i get no registration (asterisk CLI shows nada in the way of connection attempts).

When using the iphone on 3G, using the internet IP address of my core works. Since obviously using when connected via 3G won't work, this means I have to switch the server name each time I go on and off wifi.

Any ideas why I can't use the internet IP when inside the linuxmce network?

Users / Method for selecting new features for implementation
« on: August 21, 2009, 05:11:03 am »
I think we need something more sophisticated than the web forum polls to determine feature priorities. Supposing we used a matrix like in the attached?

0 means will not contribute to
1 means will contribute, but least wanted.
10 means will contribute, and most wanted.
A number can be used only once per voter.

Users / Green list in new Titanium skin
« on: August 10, 2009, 07:23:37 pm »
Just updated to latest 810 and switched to Titanium Blue skin and have the following problem (see attached image).

Tried titanium silver and had the same issue.

Feature requests & roadmap / RX8001 Wifi-IR-extender
« on: July 24, 2009, 04:10:56 pm »
Would be great if support for a device like this could be added for those of us who can't lay cable for ethernet-based ir extenders.

Users / Z-wave device compatibility question
« on: July 21, 2009, 07:02:22 pm »
I'm looking at and wondering what the model# is for the US version.

The first link points to a European version of the product.

The second link points to a product catalogue (not a particular model). From this I found two models - ZDP100 and ZDP100 v3.2 - Are either of these compatible with LMCE?

The third and fourth link point to UK versions.

Also does anyone know if these modules will work in an older house with no ground plug?
