Hi,
I've recently purchased a Dell vostro 3350 laptop, and to save battery,
I was planning to disable wifi, when it wasn't required. On my old
laptop I could use the rfkill package like so:
rfkill block wifi
But it seems to have no effect on my Dell. The wifi hot key on the
laptop does not seem to work either (from the console). Does anyone have
any other ideas? If I do ifdown eth1 to bring down wifi, is it likely
the wifi will still be consuming significant battery?
Thanks for any help,
Dan
I had a printer with 160M of RAM and some print jobs were failing. The spool
files that CUPs was using were about 220M in size. Obviously 220M spool files
and 160M of RAM isn't going to work.
I upgraded the printer to 288M of RAM, which would hopefully be barely enough
to print those files. CUPS is now generating ~360M spool files for the same
print request (printing a page from a flash-based web site).
It seems like CUPS is asking the printer (Brother HL-3040CN connected via LPD
protocol on Ethernet) how much RAM it has and is then using more!
Is it possible to configure CUPS to limit it's spool files, dropping quality
if necessary?

Hi,
Got an odd situation here, where I can't find my volume group any more.
Earlier tonight I moved my logical volumes from an old drive to a new drive
Before, I had
sdf1 - /boot
sdf2 - pv - system volume group - contained root, swap, home
To move things, I did a pvcreate on the new partition, sdg1
then vgextend system /dev/sdg1
then pvmove /dev/sdf2 /dev/sdg1
Sure enough, it moved all my lvs over.
Was then able to 'vgreduce system /dev/sdf2' and 'pvremove /dev/sdf2'
Lastly, moved /boot contents to be inside /, and unmounted /boot
My next plan was to install grub2, chainloaded, since I'd need that to boot
from inside an lvm. At this point, ubuntu didn't like it, and errored on
configuring grub-pc, saying it couldn't detect the filesystem.
Stupidly, I decided to reboot, at which point it loaded grub (1), booted the
initrd/kernel, and then couldn't find root.
Inside a rescue environment, sure enough, if I do 'pvs', I can see my pv,
but it doesn't have a VG.
Any suggestions on how to rectify this? Why doesn't it know it's part of
the 'system' volume group? I presume once it remembers this, I should be
able to boot again.
cheers,
/ Brett
Hi,
I've been using an Asus netbook for the last 2 years or so and feel I
need a bit more power!:)
I've done some preliminary research, but not quite sure where to
start. Basically my top requirements are:
1) Reasonable CPU apparently I5 is supposed to be fairly good?
2) 6 hrs + of battery life
3) I'm looking to spend around the $1200 mark give or take.
4) Linux compatible of course!
I also wouldn't mind a smaller laptop eg. 12 or 13 inch as I'm using it
in a class room environment, although this doesn't really matter too
much.
I checked out a few of the lenovo thinkpads (T series I believe, but
could be wrong) and these were way outside of my budget. I also
investigated the hp envy, but this seemed to have poor battery life.
I also checked out the mac book pro which looked ok... However,
apparently the linux install is a bit more tricky. Does anyone have any
ideas on any other machines? Is the mac book pro something I should look
into? The only draw back I see so far is the battery that can only be
replaced by Apple...
BTW, not too concerned about graphics as I'm blind, just need something
that is sufficient for any day to day use by a sighted person,
eg. navigating the desktop or reading text...:) (I don't need any high
performance graphics)
Thanks for any suggestions,
Dan
Hi all,
Today, my server was rebooted (due to a 17min power interuption), and I
was greeted by an email from it saying that it couldn't start up Virtualbox.
My server is running Debian's kernel image 2.6.32-5-vserver-amd64.
Yes, I AM running two virtualisation solutions on here - I didn't like
Xen when I tried it for a couple of months, I just couldn't get the hang
of it despite reading heaps of tutorials about it. Linux Vserver
provides a very light (in terms of overhead) way of running multiple
virtualised Linux "servers" through extensive use of security contexts
and the like. But I also wanted to run a single Windows server
instance, so hence the use of Virtualbox.
The virtualbox email states that I need to ensure I have
virtualbox-ose-dkms and the kernel header files installed.
I have virtualbox-ose-dkms installed, but somewhere along the way my
linux-headers-2.6.32-5-vserver-amd64 package became uninstalled.
Instead I have headers for 2.6.37-1, 2.6.37-2, 2.6.38-1, 2.6.38-2,
2.6.39-2 and 3.0.0-1, but none of the corresponding kernel images... Go
figure.
So I'm thinking I'll upgrade to a newer kernel, but none of the kernel
images mention vserver in their name, nor directly indicate that they
support it either.
I am willing to go down the path of rolling my own, and packaging it up
with make-kpkg (from kernel-package) so that I don't break apt's idea of
what's installed...
Therefore, can anyone confirm for me if I upgrade to 2.6.39 or 3.0.0,
will I still be able to use my Linux vservers (I really do NOT want to
have to rebuild them all within another virtualisation environment)?
Or has Xen become the defacto (and possibly only) virtualisation system
that Debian's pre-packaged kernels will support?
Cheers,
Tim Lyth.

FYI, saw this on slashdot recently. thouught you might be interested

"Smartphone maker Sony Ericsson has decided to work closely with
developers creating custom Android ROMs for devices in order to
learn from them. The company said in a blog post that it has decided
to support an open source developer group called 'FreeXperia,' which
creates custom Android ROMs based on the CyanogenMod for several
Sony Ericsson phones like the Xperia ARC and Play. Sony Ericsson
maintained that it does not approve of some of the work carried out
by independent developers but was keen to work with people who were
creating custom ROMs."

BOFH excuse #399:
We are a 100% Microsoft Shop.
I want to install libvirt-bin under Debian, but it depends on
libxenstore3.0 and I don't want it installed because I already have xen
installed (built from source) and installing the debian version breaks
it.
What are my options? I can think of:
1. rebuild the libvirt-bin and remove the dependency (easy enough, but
the next upgrade of libvirt-bin will break it)
2. force package installation (not even sure I can do this anymore)
3. create a dummy libxenstore3.0 package with a high enough version that
nothing can ever upgrade it
4. install libxenstore3.0 but somehow redirect the files (?)
Any other suggestions?
Thanks
James
