i’ve been having issues w/ /dev/dsp not being available lately and it’s because nxesd keeps hanging around on my system.

$ sudo lsof | grep dsp
nxesd 11945 flipp 4w CHR 14,3 10785 /dev/dsp

yup. nxclient/nxserver use esd (the enlightenment sound daemon) to manage pushing sound w/ the remote display. i’m not sure why it’s grabbing /dev/dsp for a session where i disabled multimedia support but killing off the nxesd process fixed sound. to fix it permanently, just change your sound playback device to esd in system>preferences>sound.

i was a little bummed to find out that you couldn’t just update between the mythbuntu alphas… i finally got around to tossing the 8.04 beta on my mythtv frontend and firewire input/capture WORKS! i also moved the pvr500 into the t105 and got that working. the only issue i’m having right now is figuring out how to get the primary backend and secondary backend to play nicely.

i also figured out how to get nxclient to work in mythbuntu. i never did figure out how to get xfce to start properly (it wouldn’t start in a window and it would render xfce over my current window manager) so i cheated and just installed ‘ubuntu-desktop’. not gnome, or gnome-desktop…. heh, yeah i’m slow.

i’m still not happy with the way avahi or NetworkManager start networking in gutsy. i was having an issue with an nm connecting to an open access point instead of my access point, quick look at the NetworkManager faq and i found how to remove essids from NetworkManager.

How do I remove networks I no longer wish to connect to?
From the command line run the following replacing <SSID> with the SSID of the network you wish to remove:

    $gconftool-2 –recursive-unset /system/networking/wireless/networks/<SSID>

You can use the “Configuration Editor” (gconf-editor) to browse the networks listed in that configuration directory, but you cannot remove the SSID’s folder using the GUI tool.

arg. everytime i have to play with ‘gconf’ and ‘tool’ in it reminds me of a windows registry. unix/linux is supposed to use flatfiles for config files! eh, atleast i can remove the unwanted networks/access points now. oh, and if you’re working how nm picks networks….

How does NetworkManager select which wireless network to connect to?
NetworkManager only attempts to automatically connect to networks you have previously told it to connect to. If it finds multiple wireless networks that you have connected to in the past, NetworkManager selects the network one you connected to. If NetworkManager isn’t connecting to the network you want, try to force it to connect to the network you wish to be connected, and NetworkManager will remember that setting next time.

even better, it looks like debian/ubuntu modified NetworkManager for their distos.

My Card is not recognized by NetworkManager and I am running Debian or Ubuntu:
Debian and Ubuntu modified NetworkManager so that it would not manage any devices listed in /etc/network/interfaces. If you open this file and comment out the lines for the interfaces you want to manage and reboot NetworkManager will see them. **Do not comment out l0**

bleh. not sure whether to try a new NetworkManager build or just remove it completely and use something else to manage my wifi.
