[gentoo-user] Seeing USE flag descriptions for a package
Hi there, When I install a new package I run `emerge -pv foo` to look at the USEs it supports. In the past I have looked these up just by grepping, e.g.: $ grep foo /usr/portage/profiles/use.* /usr/portage/profiles/use.desc:foomaticdb - Adds support for the foomatic printing driver database $ However I have recently learned to use `euse -i foo` instead. This is much more convienient than grepping because one can use the Bash history: up-arrow, ctrl-w to delete the last word type in or paste the name of the next USE to check it. However this is clumsy when you have a package (like mplayer) with many USE flags. What I would like to be able to do is: $ $magicusecommand category/package doc - Install HTML wxWidgets docs and wxpython API reference. examples - Install interactive demo module browser and sample applets. samba - Adds support for SAMBA (Windows File and Printer sharing) $ The command should print out the descriptions for ALL the USE flags supported by the category/package, but only for that category/package. Ideally it should show if they're currently enabled or not. I can't be the only person to desire this feature - surely there must be a package or command do do this. I can't find this in `man portage` as an advanced version of `emerge -pv package`. Can anyone tell me what $magicusecommand is called, please? Thanks in advance, Stroller.

Re: [gentoo-user] Applying patches without needing overlays and modifying ebuilds

Thanks, dhk According to the cups site, your printer is not in the list. http://www.cups.org/ppd.php?L From my experience, Lexmark does not support Linux very well. I always stick with HP myself. They seem to have drivers for all but a very new printer. Usually when a printer has been out a few months, there is a driver for it. Plus, HP has better Linux support in other areas as well.

Stroller. Yes, just add cpudetection to those or put it in in make.conf. If you want to set the proper flags there's no other way but to check what features the particular CPU model supports. The only sure thing is that no Intel CPUs support AMD's 3now and 3dnowext. Everything else depends on the moment the particular model was released, because those features were not initially specified but being added as time passes by. Some random thoughts... The packages that could utilize some of those cpu instruction sets are not so many. Try euse -i sse for example and see which programs would be affected if you change it. Then...trial and error. :) Last but not least. If you have a (supported model of) NVidia video card and don't mind using the closed source driver, you could try VDPAU. It's a technology for Linux for offloading video decoding from CPU to GPU. For a reference mplayer takes about 30% on my CPU to play HD clips normally and about 2% when using VDPAU.

I have found different names possible : 11-x11-synaptics.fdi 99-x11-synaptics.fdi Why the donkey would it be 99 or 11 ? Since (as I see below) you've added hal to your USE flags for the xf86-input-synaptics driver, you should already have the synaptics HAL data installed -- the post-ebuild messages would tell you where those are. Currently, the stock HAL rules are installed into /usr/share/hal/fdi/policy/10osvendor/11-x11-synaptics.fdi The reason it's number 11 is because the synaptics Xorg driver exposes itself to HAL in a way that also looks like a mouse, so it matches all on the HAL rules for standard pointer device behavior. The synaptics rules need to override the normal rules, which are in the file 10-x11-pointer.fdi, so the synaptics rules go into 11-x11-synaptics.fdi and get loaded second. The file named 99- is most likely a suggestion from someone for a local customization to the policy, since it will be loaded after everything else. Since the synaptics rules are included in the base HAL policy now, there's no need for the 99- file. The thing is that I don't know how to match my touchpad with the fdi policy or that I have another unknown problem. You should not have to do anything to get your touchpad recognized by HAL as a synaptics device, since you already have the HAL policy file locally. You can use lshal(1) to ask HAL what devices it found, for example: lshal | grep -9 input.x11_driver You should see a result which includes: input.x11_driver = 'synaptics' If you back up a few lines you will see the info.capabilities set, which should include items like input, input.mouse, and input.touchpad. The default settings are in the FDI file in /usr/share, which will also show you how to override any of those settings. Basically, anything that used to be an xorg.conf option can be set using an input.x11_options.OPTIONNAME key. For example, to turn on SHMConfig so you can use the synaptics utilities: ?xml version=1.0 encoding=ISO-8859-1? deviceinfo version=0.2 device match key=info.capabilities contains=input.touchpad merge key=input.x11_options.SHMConfig type=stringOn/merge /match /device /deviceinfo Put this in an FDI file inside your /etc/hal/fdi/policy folder, such as /etc/hal/fdi/policy/10osvendor/11-x11-synaptics.fdi

Normally paludis will (or it used to anyway) complain loudly when the permissions werent set correctly. If they are set correctly what happens when you try to pull the git repo manually? - Nick As I wrote in my original post I receive somehow similar error when I try to install the package using emerge. I am not sure whether it can be some permissions problem, the git-src subdirectory is successfully created in the distfiles directory, but then git clone command fails. When I run the git clone command manually from the command line then it works without problem. The directory permissions are as follows: drwxrwsr-x 4 portage portage 94208 May 26 20:07 distfiles The git-src subdirectory is then automatically created by paludis and its permissions looks like this: drwxr-sr-x 2 portage portage 4096 May 26 20:10 git-src When installing with emerge then the git-src directory is created with little bit differrent permissions: drwxr-sr-x 2 root portage 4096 May 26 20:13 git-src I am not sure if these permission are set correctly but it always worked for me and I have no problems with ebuild that fetch sources from svn repositories.

So My USE flags are set correct (for hardware) aren't they? No, you have it wrong. The ebuild does not magically change the USE flags based on what you have. It will build according to what you tell it, no more, no less. USE=cpudetection causes special code to be compiled into mplayer. Think of it this way (a highly simplistic explanation that gets the point across): mplayer is built with routines for every possible optimization. At RUNTIME, when mplayer starts, it figures out what you have and what you can use, and remembers for itself the routines you can't use and does not run them. cpudetection changes runtime behaviour, not compile time behaviour, and does not change your use flags at all. When you hashed out the line in /etc/make.conf, all you proved is that with the exception of oss, your configured USE flags for mplayer are the same as the default for your profile and mplayer. -- alan dot mckinnon at gmail dot com
Re: [gentoo-user] Auto-mounting USB drive?

The only thing I can think of is that your USB drivers or the kernel module that does USB mass- storage is not loaded in time during boot. Aren't there any messages about failed mounts amongst the kernel messages on the screen? That's most likely the problem, I had a similar situation trying to mount an SD card at boot time. Two solutions are to mount the device later in the boot sequence, from /etc/conf.d/local, or to build the necessary modules into the kernel. Since you're mounting the USB device on boot, there's no point in having separate modules for USB. -- Neil Bothwick Stroller Neil, Thanks. I don't know why but I hadn't considered the idea that the USB driver would be better built into the kernel for this application. Basically, this is a little PowerPC Mac Mini that I've turned into a new HD Homerun/USB video storage MythTV backend server. I want to be pretty confident that the hard drive is mounted because the machine is headless and sitting in a corner. If someone turns it on after a power failure I don't want to have to mess around to get the external storage mounted. I don't need the drive mounted at boot time, but I certainly want it up and running before the mythbackend script gets started. If I get a power failure and someone restarts everything it could be in the middle of a previous recording and I need the partial recording to end up on USB. I'll look at building in the USB driver into the kernel and using e2label also. I did actually manage to get it working using some udev rules that I found in the forum, but I must say I don't really understand them and never thought they were necessary. I'm glad you guys are thinking the same way. Thanks, Mark

You can do whatever you wish as long as USE contains all you need in the
end. Example:
USE_FOO=this n that
USE_BAR=some more flags
BLAH=whatever else there might be
USE=${USE_FOO} ${USE_BAR} ${BLAH}

Hi, sure I want to know what they do mean and I hope I already do with those I defined for my make.conf. The point is another. Like I set up another PC with other cpu and gpu I want to be able to just copy and past those use flags not related to hardware very easy. One the other hand hardware use flags shouldn't change for my pc so I do now don't touch this area :-) Doesn't this make sense? kh

The idea is to enable the cpudetection flag and all USE flags which correspond to one or another extended instruction set (EIS) and build mplayer with support for all EIS plus extra code for *run-time* cpu detection. This way mplayer *could* use all EIS that are implemented in its code, but *will* detect which EIS are supported by your CPU and use only them. In other words the same binary will use different EIS on different CPUs. There could be problems if you had enabled all the EIS flags globally (in make.conf) instead only for mplayer, because other programs don't have the run-time cpu detection feature and will fail in their attempts to use for example 3dnow! on an Intel CPU.

Editing make.conf is easy, knowing what to put in it is the hard part. what are all the possible flag names you can enter? There are hundreds. What do they all mean? How does enabling or disabling a particular use flag effect the build of all packages that use it? Which packages share a use flag? Which flags are mutually exclusive? Which ones are enabled by default, that you want disabled? There is much more involved than simply editing a file.

[gentoo-user] Question about xorg and a kill process
I know the subject is a bit lacking but here goes. I'm thinking about trying this xorg-server upgrade again. I been thinking about a way to do this and not have to pull the plug on my rig if it fails, which I bet it does. This is the command I am thinking about trying. /etc/init.d/xdm start sleep 5m /etc/init.d/xdm stop I'm thinking this way. Start X first. If it fails, it will stop in 5 minutes and come back to a console. Think this will work? If xorg works, I can switch back to a console and ctrl C the command and carry on. Thoughts? Better ideas? Dale :-) :-)
