About the third, hopefully it won't be needed again :) After a post that
quoted the correct bug report but then the wrong "solution" I couldn't
help myself.

Ironically, I rebooted a headless server yesterday, one on which I'd
updated LVM about a week ago and not changed the config. The box has a
separate /usr on LVM and no initramfs (still on old udev) so nothing
worked after a reboot, especially SSH :(

[gentoo-user] «-»: [gentoo-user] Wifi autodisable on lan

[Samuraiii]

  
  

  
  I've come across this
http://johanlouwers.blogspot.com/2011/03/linux-check-interface-status.html
  
  But this isn't helping me:
  right now I'm on wifi only but when I run ifconfig I get this for
  eth0 (my lan card)
  
  eth0  Link encap:Ethernet  HWaddr 00:41:70:52:5c:59  
    UP BROADCAST MULTICAST  MTU:1500  Metric:1
    RX packets:0 errors:0 dropped:0 overruns:0 frame:0
    TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
    collisions:0 txqueuelen:1000 
    RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
    Interrupt:46 Base address:0x2000 
  
  so that grep UP will return 1 even if cable isn't plugged in.
  
  But i found ethtool which does what I need so thank you for your
  help.

I think Neil makes generous allowances for those of us with volatile memory 
and needs of frequent reboots!  ;-)

[gentoo-user] libmp4v2-1.9.1_p479 (was problems with digikam)

[luis jure]

i realized my problems trying to rebuild digikam-2.5.0 were related to the
latest version of media-libs/libmp4v2 (1.9.1_p479), that i had upgraded a
couple of days ago.

after masking it and downgrading to libmp4v2-1.9.1, i could compile digikam
again. problems that i was having compiling other packages also
disappeared.

[gentoo-user] multiple bluetooth devices

[wdk@moriah]

I am using a single BT usb dongle to communicate over rfcomm with two BT 
Arduino based devices.  Individually they work fine but if one is connected (to 
rfcomm1), but any attempt to use the other (rfcomm0) fails and knocks the first 
into limbo requiring recovery.

The BT spec implies up to 8 clients can communicate over a single BT device.  
Ive also tried using different channels for each but the clients look like they 
are channel 1 only.

Can anyone see a way around this or will I need to do some kind of polling to 
make sure the other device isn't using it before attempting comms?

The server is using bluez 4 with the standard gentoo files with the two devices 
parameters set in /etc/bluetooth/rfcomm.conf.

That bug report also showed the correct solution. There's no need to
downgrade, just change the locking_dir location from /var/lock
to /run/lock. Not only is this simpler and faster, it means another
update can't cause the same problem.

LOL. Because you'd be having a laugh if you were suggesting that the 
Gentoo-devs should properly document their USE flags.

I made a polite request for them to do so on the -dev list in 2004 (I'm pretty 
sure I did twice) - this is an area in which there has been no improvement in 8 
freakin' years!

I got this error, and saw a bugfile on Gentoo, just downgrade to your
previous working version and you will get it working again.

[gentoo-user] /etc/pm/sleep.d/ problem

[Grant]

My Dell XPS 13 Ultrabook goes to maximum brightness whenever I close
the top and I have to execute the following command in order to
control the brightness again:

echo 0 > /sys/class/backlight/intel_backlight/brightness

The following script in /etc/pm/sleep.d/ is said to fix the problem:

http://ubuntuforums.org/showpost.php?p=11783826&postcount=40

I created it and made it executable but it doesn't work for me.  Does
anyone know what the problem might be?

You could do this with ifplugd, but the easiest way is with Wicd, which
can run actions on connection and disconnection of any interface.
