= QandA =
Here's a place to ask new questions and get answers, especially for topics that haven't got their own wiki page yet. Answer can be included in a wiki FAQ.

Q: how do I tell apt-get which http-proxy to use ?
A: Set the environment Variable {{{http_proxy}}}: {{{export http_proxy=""}}} or {{{export http_proxy=http://uid:pw@proxy:port}}} if the proxy needs authentication. There is also an option that can be set in /etc/apt/apt.conf.d.


Kernel-Patch HOWTO (Debian-Way)

Where can I get this information? Or could sb write this HOWTO in this wiki?

Oh, there are many docs like these, I put some here CompileKernel. //mawi


Debian Wishlist

Is there a Wishlist for further debian releases that can be used by debian users ? One can post wishlist-bugs to individual packages, but what about more general requests ?
que es lo que es
Thanks for your answers.

> I don´t know if it exist, but I want one. Regards (perhaps in yahoogroups if no here ??) .

answer: RainerKulow
> dont know one yet, but there is a site that defines goals(wishes) and solutions [[DebianNPGoals]].

> You can also post a RequestForPackage bug against wnpp to ask for a particular package. --EvanProdromou

General wishes have different ways to address depending on which part of Debian you intend to change. What do you intend to do?




Q: How do I multi-boot Debian GNU Linux?

A: Use Lilo, Grub or similar multi-boot screens. --LarsOlson


Q: What can i do with the kernel-header ?

A: Compile something that depends on kernel. nVidia drivers for example....


OK, I'm doing something crazy.
I have an ancient box with a 2 GB SCSI hard drive
that I'm installing Debian on.
Nowaways, that's a pathetic amount of disk space.
But instead of doing the normal, common process
of getting an IDE drive and plugging it in,
no, I had to plug in a USB hard drive.

Unfortunately, I haven't figured out how to boot the USB drive,
so I think I must keep the /boot partition on the SCSI drive.

Can I '''move''' the root ("/") partition from the SCSI drive to the USB drive ?

[[http://www.debian.org/doc/manuals/users-guide/ch-ctsystem.en.html#s-mdwtss|User's Guide]] discusses moving a partition to a different hard drive, but I don't think that process works with the root ("/") partition.

== GNU/Linux and Hardware ==
Q: Is there any compatibility issue that I should know about the HP/compaq nx9010 notebook hardware with debian bfore purchasing it ?

A: Probably the easist way to confirm hardware compatability is to try before you buy. Whilst vendors are unlikly to let you reformat the hdd of a laptop and install Debian, most will let you run a [[LiveCD]] such as the Debain based Knoppix. If Knoppix can see and talk to all the hardware then there is no reason why yopu shouldn't be able to get a fully operational Debian installation. -- AndySimpkins


Q: how do I get Debian (updated/upgraded Knoppix) to sync a Palm m505? I've combed through several excellent online resources --
2.3. USB Connection
and believe I have tried everything. I have the latest version of [[JPilot]] and pilot-link. The visor and usbserial modules are loaded (manually), the Palm syncs elsewhere, the cradle is live, and the ports work with other USB devices. But whether [[KPilot]] or [[JPilot]], no activity is detected after I press hotsync, then use a variety of steps to initiate a conversation with the port. I'm using a Dell Precision 450, 512 megs, and both KDE 3.1 and Gnome 2.2. (No luck in either window environment.) My only clue: apt-get upgrade said it would add (although I had to do it manually) " none /proc/bus/usb usbfs defaults 0 0 to your /etc/fstab file" -- but that "only root will be able to access the USB devices with this setup." I've tried in root, too, but nada. Anything I've overlooked?

try this: it might be that your usb-system doesn't accept the port number it gets assigned at first, (have a look at my two USB -related posts see DanielGermer )


Q: How do I use a midi keyboard with debian? In particular,
the the m-audio keystation 49e usb-keyboard (among the [[http://www.apple.com/ilife/garageband/accessories.html|apple garage band accessories]]). lsusb says
  Bus 002 Device 005: ID 0a4d:0090 Evolution Electronics, Ltd

I'd like to use it with, say, DebPkg:beast . DebPkg:hotplug seems to relate the device to the "audio" module in 2.4.16. How can I confirm that it's connected to /dev/midi? Do I need to use alsa? I've been googling for a
couple hours. I tooks some
[[http://www.ilrt.bris.ac.uk/discovery/chatlogs/rdfig/2004-03-26.html#T03-09-20|notes in irc]]

I read the [[http://www.midi-howto.com/|linux midi howto]], but it doesn't suggest any software that you can use to confirm that your hardware setup is right. in particular, it says to look at /dev/sndstat, but I get "no such device", even though sound output is working fine. -- DanConnolly

Having some problems with hdparm and dma settings under debian sid (unstable).{{{
 hdparm -t /dev/hda
 Timing buffered disk reads: 20 MB in 3.00 seconds = 6.67 MB/sec
 hdparm -d1 /dev/hda
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Operation not permitted
 using_dma = 0 (off)
 hdparm -Xudma2 /dev/hda
 setting xfermode to 66 (["UltraDMA"] mode2)
 Segmentation fault

I am logged on as root when doing this. Any use of the -X switch causes a segmentation fault. The drive is a [[30GB]] Fujitsu ide hdd, capable of [[UltraDMA66]]. I've had this working before on Woody. Any ideas?

Partial Answer:
I had the same problem with my setup, the resolution was obtained by twiddling with the DMA kernel parameters (I use kernel.org unpatched).

Another hint would be to check whether your mainboard's IDE chip is supported by the kernel in use.

Q: There seem to have been changes in the usbfs, particularly that /proc/bus/usb is no longer mounted as from June 2009, see DebianBug:483392. What is the story behind this?

CategoryProposedDeletion: the wiki is a bad place to ask questions, debian-user or forums.d.n is better

I thought the idea was to ask questions whose answers would be the basis for a new wiki page. I was looking for a page on the usbfs.
