[gentoo-user] ATI-drivers versioning system - I'm confused
Hi, would anybody please to kind to explain the x11-drivers/ati-driver versioning system to me? I'm waiting for a version that supports Xorg-7.x . From the bug report http://bugs.gentoo.org/show_bug.cgi?id=290739 it looks like version 8.721 supports Xorg-7.x and would thus be more recent than say 10.2 What's the difference between the 8.x and the 10.x series?

[gentoo-user] X11 keyboard permanent mode switch ?
Hi, I've set up the 'menu key' (left to the right control key on an US keyboard) as 'mode switch' (to enable entering non-ASCII characters). By (bad) chance I discovered that entering this menu-key together with the right control-key seems to lock the mode switch (so I have to press it again (each time) to enter normal ASCII characters). If I'm lucky I can revert this to normal if I press the menu-key and the right control-key 'at the right timing'. Is this a bug or a feature (xorg-server-1.7.6) Many thanks for a comment, Helmut. -- Helmut Jarausch Lehrstuhl fuer Numerische Mathematik RWTH - Aachen University D 52056 Aachen, Germany
[gentoo-user] Xauthority and su
Hi, when maintaining a machine from remote I sometimes have to switch to a non-root user (whose password I don't want to know) to try something out. For that, I log into that machine by ssh -Y r...@ Now, how can I switch to user USER such that the X credentials are copied. Unfortunately, sux (from X11-misc/sux) doesn't work in that case. I always get X11 connection rejected because of wrong authentication. Are there any means to achieve this?

Hi Jonas, unfortunately, I don't understand your advice. I do have X11 forwarding configured and I don't have any problems when working as the same user for which I logged in via ssh -Y.

[gentoo-user] RFC ebuild for a non-standard Python package
Hi,
I'd like to install the new package expy on sourceforge
http://expy.sourceforge.net/
Unfortunately, the contents of it are a bit non-standard.
First, the tarball has the unusual name expy.6.6.tgz.
Second, it untars in to the current directory (no subdirectory
expy-6.6)
Third, it has setup.py and some helper modules in a subdirectory
'src'.
My current (working) ebuild is a litte bit brute force.
I'd appreciate any comments on streamlining and standardizing it.
Many thanks,
Helmut.

Re: [gentoo-user] OT: DVD-Container ?
On 8 Jun, meino.cra...@gmx.de wrote: Hi, I am using k3b to burn dvds/cds. As most programs of this kind, k3b can /copy/ but not /move/ data to a DVD. Therefore, when trying to find tose files, which exactly sum up to the size of a DVD (by the way: I know DVD- sizes from a little below 4.3 GB to over 4.7GB...what is the truth?) I end up with a selected file here and another one there. After the DVD is finished it is --hrmm-- not efficient to find those in the related directories to remove them after a successful copy. Now I am looking of something like a virtual DVD to which I can /move/ and move back files. The DVD should report no space left on device exactly at the same point when a real DVD is filled. I thought of one extra partition of the same size a DVD but since the filesystems will occupy different amount of space... On the other hand: A iso-image-file on the harddisk would be nice, but that filesystem isn't made for moving files back and forth... Any ideas to solve this??? Different idea: have a look at app-cdr/gaffitter It approximates the so-called knapsack problem of optimal packing. You can then use this information to burn and afterwards delete the files.

[gentoo-user] mkfs.btrfs check for bad blocks - howto
Hi, when creating a file system on a partition on a brand new hard disk, I have always used the '-c' twice to check for bad blocks. This works for ext3 and ext4. Now, I'd like to use a btrfs file system on some partitions but the '-c' option (to mkfs.btrfs or mkbtrfs) seems to have gone. What can I do about this?

If you have a 4-week old version of /var/db, you can probably use that for the sake of rebuilding/unpackaging system and world. Hopefully, system and world won't have changed so much in four weeks that a ground-up rebuild will be more efficient. Yes, I'm trying that. Though I've encountered some difficulties. E.g. the 'old' system had gcc-4.4.3-r2 in slot (4.4) while the /usr partition contained gcc-4.4.4. Trying to emerge gcc-4.4.4 (binary) portage went into a loop (at least it would have taken more than an hour on a fast machine). I had to fetch /etc/env.d/gcc from a similar machine here. The problem seems to be that during installation portage tries to remove a version which isn't installed anymore. Meanwhile I could reinstall gcc-4.4.4 which was the biggest corner (hopefully).

But could tell us a bit more about the system on which this does *not* happen? How is it different? Is it an x86 or amd64? multilib? Is it a more recent install than the other one (so that there should be no left-over cruft from, e.g., old python versions)? Sorry to say, but I don't know the difference. Both have nearly identical hardware (AMD Phenom II, same chipset) Both are updated each day (~amd64) and both have nearly the same set of packages installed.

Putting some echo statements into configure doesn't work, it seems to regenerated on each 'ebuild compile' I'd call the configure script by hand, search for it in /var/tmp/portage. If it gives the same error (which may not be the case because you do not give it the same arguments as portage does), add the echo statement, and try again to see the value of $ax_python_header. I guess it has whitespace in it, so the test fails. This would be solved by quoting the variable. The configure script is created from something like configure.ac, you will probably find the test statement there, too. You could change it (adding quotes), and use ebuild ... compile to build. Please file a bug for the package. Many thanks, Alex. It turned out that pythonmagick's configure contains ax_python_header=\ `locate python$python_version/Python.h | sed -e s,/Python.h,,` which I regard as very strange style. Since I have a mirror /Store1/usr_mirror locate locates both /usr/include/python2.6 and /Store1/usr_mirror/include/python2.6 I'm going to file a bug report. Helmut.

[gentoo-user] Portage internals : shadow root
Hi, when portage installs a package, it first installs it into some shadow root. Then it records all files installed before it moves the files to the real root.

Because it's a sneaky P.O.S. and goes to extraordinary lengths to nuke all your hard work done without it. And how you deal with file collisions is up to you. Yast really won't like you if you overwrite some config file with your own testing version. Thanks Alan! Unfortunately, I don't understand how this can work. Simplify using PREFIX failed for me since many packages record the full path for configuration/data/help files etc. in the generated binaries or libraries. When moving such an application/library it will still search for those files in the build directory. I would image Portage uses some sort of chroot (then the pathes are identical) Furthermore, I cannot remove yast since I'm only a guest on such boxes. Normally I'd use a PREIFX=/usr/local/MYAPP but some application still install something into /etc/ or similar and I'd like to catch these cases. Helmut.

[gentoo-user] Problems with ancient ATI graphics card
Hi, this is a bit off topic, since it primarily concerns a laptop running OpenSuSe 11.3, but I do need your help and I known there are experts here. This old laptop has a radeon RV350 (mobility Radeon 9600 M10) graphics card. There is an xf86-video-ati driver installed. Now, when booting with the (default) radeon.modeset=1 the graphics is dead slow (not only for glxgears : 200 frame/s but for my OpenGL application (Impressive), as well). Now, when I replace the option on the kernel command line to radeon.modeset=0 glxgears is much faster ( about 1800 frames/s ) BUT my OpenGL application (python gtk + opengl) now freezes the whole machine - only power on/off can revive it. Hopefully, someone has an idea on what is going wrong here. (The hardware is too old for a recent ATI closed source driver supporting a recent kernel 2.6.34.x) Many thanks for your help which is very much appreciated. Helmut.

I usually read the ebuilds and grep directly through files to find
this kind
of stuff :-) I find it easier than remembering commands.
The xorg-server ebuild says:
IUSE_SERVERS=dmx kdrive xorg
IUSE=${IUSE_SERVERS} doc hal ipv6 minimal nptl tslib +udev
So it uses all those flags, and udev is on by default unless you
explicitly
say otherwise somewhere.
I haven't found anything in 'use.mask' in my profile
default/linux/amd64/10.0/desktop
Post the USE section from emerge --info, the output from
emerge -vp x11-base/xorg-server.
Unfortunately, that's too late now.
Meanwhile I have add
x11-base/xorg-server -hal
to /etc/portage/package.use
the output from
grep -r udev /etc/portage/*
grep -r hal /etc/portage/*
That didn't show any hal entries.
and let's take it from there.
Finding stuff in profiles is tricky, you have to search upwards
through the
directories, not downwards.
Many thanks, Alan.
Meanwhile, upgrading to xorg-server-1.8.2 went smoothly and
I've removed /etc/hal/fdi/policy/x11-input.fdi

[gentoo-user] how to rebuild gentoo on a somewhat different hardware
Hi, I have an up-to-date ~amd64 GenToo installation with has been built on a current AMD64 (Phenom II) machine where I used -mtune=native in etc/make.conf since I didn't think of the case that I would need to port this system to a somewhat older Opteron based machine (still AMD64) But after cloning the system, some fundamental utilities die of an illegal instruction. So I have to rebuild GenToo nearly from scratch. emerge -e world doesn't work. So, what is a reasonably fast method? I'd like to keep /etc /usr/portage except /usr/portage/packages /var/lib/portage Is there a fast method e.g. by using the Gentoo based SystemRescueCD to reinstall a very basic system, such that I can do emerge -e world. It looks as if the gcc tool-chain is intact since I could compile a kernel without any problem. But some utilities, e.g. find, die of an illegal instruction. Many thanks for any hints saving me a couple of hours work, Helmut.

Seriously - you know you are looking at doing emerge -e world and will need to fiddle stuff to make it complete successfully. If you just reinstall, put your old world file and /etc/portage/ back then let portage have at it, that is exactly what will happen. You'll have 30-45 minutes of setup work and a high level of confidence it will complete successfully. Trying to fix the existing installation is potentially many hours of poking around to see what changed, potentially several goes at running emerge -e world, hair pulling, and you will probably give up and just reinstall anyway. I'm assuming you are looking for the easiest, fastest route to success with the least pain, and that your days of poking into portage to see how things work for fun are long over.

My problem was that I did use rsync -auHz --delete --exclude=/A/SourceDir/ DestDir/ .^ because A is a directory on DestDir. But it turned out that this does delete A on DestDir since A is a symlink on SourceDir and the include/exclude pattern is applied to the SourceDir only.

Sounds like the big guns approach, can be valid at times. I'm usually the first one to chip in about emerge -e world being stupid when someone reads the gcc upgrade guide, but sometimes you have a box that just will not fix itself despite hours of troubleshooting. In a case like this a full remerge often fixes mysterious but actual real problems. I've had pretty much the same thing happen. In my case, 'eix' showed that I had 0.9.8p and 1.0.0 installed in two different slots. However the 3 files that belong to 0.9.8 were missing. Fortunately, I run with --buildpkg so I had a binary package lying around. Emerging it with -gK restored the files, and everything was okay. OTOH, a couple of years ago I did an emerge -e and regretted it. It kept stopping because something wasn't configured right, and I had to go through dispatch-conf on everything up to that point before I could get it to proceed. Good luck with your few days. Mine was more like 2 weeks of stop-and-go. Ah, the joys of source-based distros :-) If you break it, you get to keep all 47,392 pieces! I keep promising to leave gentoo behind and find something less thrilling. Then I use by Ubuntu netbook for a few days and come right back. It's like a heroin junkie needing his fix... I have been doing emerge -e world just recently. The first few days I felt like a disc jockey, here a use flag in there out. But then the real problem was that Gentoo is changing quite fast. All packages which failed to rebuild couldn't be rebuilt on an up-to- date machine either, since meanwhile I have installed a newer version sys-devel/autoconf and friends and some packages cannot be rebuilt with a recent version of these tools. I just didn't notice it on my master machine since there was no need to rebuild these packages. But trying to do so now revealed the true cause of the error - some bug reports. Helmut.
Re: [gentoo-user] On what to base a custom live CD?
I'd suggest SystemRescueCD. It's upgraded quite often (currently using kernel 2.6.35-x) has a ready to go X11 environment and most useful, it's an up-to-date Gentoo system, so one immediately knows where to look if there are any problems. And it has a well documented (easy) procedure for extending it. Helmut.

It needs to load one custom kernel module and then run one console-mode application. Instead of building something from scratch, I was hoping I might be able to modify an existing liveCD. There's no need for support for networking, graphics, or even access to optical or hard drives. The current version of this CD is built sort of from scrach using a labor-intensive and error-prone process. However, it does produce something that's small (less that 10MB), and boots fast (around 10 seconds). But, updating the existing CD with a newer kernel (to gain support for newer hardware) is difficult. I thought about using a customized systemrescuecd, but that takes ages to boot (almost 5 minutes). This CD is intended as something a customer can run to do a quick hardware test, and making them sit there for 5 minutes to see a 5-second test just isn't going to fly. I also looked at the gentoo minimal install CD, but that's still pretty slow (3-4 minutes), and it's not at all obvious how to add a kernel module to it.

In my head I couldn't see how the full path would not work, but the relative path would, but I tried it out all the same. I still don't understand why Alan's recommendation works ;-) I'm probably late with my reply, but I'll post it so it will be in the archives for future reference. The man page is actually pretty clear on this issue. Quote: if the pattern starts with a / then it is anchored to a particular spot in the hierarchy of files, otherwise it is matched against the end of the pathname. This is similar to a leading ^ in regular expressions. Thus /foo would match a name of foo at either the root of the transfer (for a global rule) or in the merge-file’s directory (for a per-directory rule). An unqualified foo would match a name of foo anywhere in the tree because the algorithm is applied recursively from the top down; it behaves as if each path component gets a turn at being the end of the filename. Even the unanchored sub/foo would match at any point in the hierarchy where a foo was found within a directory named sub. Root of the transfer is the directory you want to sync. Thus, if you run e.g. rsync /var/log/ /mnt/backups/ --exclude=/portage/ then root of the transfer is /var/log, and therefore the directory /var/log/portage will be excluded. If on the other hand you write --exclude=portage/ then a directory named portage anywhere in the tree under /var/log will be excluded. Without the trailing slash, i.e. just --exclude=portage any file (regular file, directory, link, whatever) named portage anywhere in the tree gets excluded. And finally --exclude=/portage would exclude a file only at the top of the tree that is going to be synchronsed. Let me add some caveat which has trapped me recently. I had (in your terms) rsync /var/log/ /mnt/backups/ --delete --exclude=/portage/ and /var/log/portage was just a symlink to some other directory while /mnt/backups/portage was a real directory. In that case rsync deletes /mnt/backups/portage ! It looks as if the directory property is check in the source tree only. Quite an unpleasant surprise. Helmut.
[gentoo-user] A desparate needs advice!
Hi, I have cloned an ~amd64 system which is running happily on a modern Opteron machine to an old Opteron machine. Unfortunately, I've built that system with CFLAGS -msse3 and msse4a and USE-flags sse3 sse4a . Since these instructions are not available on an old Opteron I had to emerge -e world which was (is) a real mess and which has taken 3 weeks now (not full time, of course) I've rebuilt the kernel (several times) but I cannot boot the machine. When I boot with SystemRescueCD and change root, the machine runs perfectly. The boot process stops after displaying the messages Freeing unused kernel memory: 356 k freed init-early.sh used greatest stack depth: 4376 bytes left I have looked at dozens of places which Google returns but I couldn't find a reason. E.g. the kernel is built with amd-64-generic. I've re-emerged sys-apps/sysvinit several times but nothing helps. So, has anybody a suggestion on what to try out or how to locate the problem? I'm more than grateful for any hints since it could save me another three weeks work. Helmut.
[gentoo-user] Python:2.7 - Save to use as default?
Hi, dev-lang/python-2.7.1 has been unmasked and with the recent autgen from today it builds cleanly. Is it safe to use this version as standard Python (via eselect) when running python-updater afterwards, of course? Many thanks for sharing your experience, Helmut.
[gentoo-user] Remove redundant entries in world - howto
Hi, does anybody know about an easy method to remove all entries from /var/lib/portage/world which would have been pulled in anyway even if they were not contained in world. My current attempt would be to write a script which executes emerge -vpc on each entry in world. If it wouldn't be removed it's obsolete in world. Unfortunately this has to be done in several rounds. Many thanks for a hint, Helmut.
Re: [gentoo-user] Which architecture ???

The handbook choices are: x86, sparc, amd64, ppc, ppc64, alpha, hppa, mips, ia64, arm. I'm guessing the x86, but I's like to be sure. x86 will do for sure. But you can check cat /proc/cpuinfo | grep address sizes If it shows more than 32 bits (e.g. 48 bits) then you could use amd64, as well. AFAIK, 64 is mean stream today. How much memory do you have installed? If more than 4G you have to use adm64 to fully use it. I'd prefer amd64 if possible, Helmut.

Many thanks for a hint, Helmut. You may find that using 'emerge --deselect some-package' to be what you need. It removeds the file from your world file, but does not unmerge the package. That command switch is the functional opposite of --noreplace. I think you will find a wealth of information in the manpage for emerge. Happy reading! Sorry, but I still don't see it. The main question is which packages might be removed from 'world'? Helmut.

It basically looks at packages in world that have reverse dependencies also in world (but only goes one level deep). Just # auditworld /var/lib/portage/world http://paste.pocoo.org/show/302273/ Many thanks, I've updated it a bit to generate a new world file (using python3) http://paste.pocoo.org/show/302337/ One should have a look at the diffs (e.g. meld) before replacing the old world file.

[gentoo-user] Kernel doesn't use all of the available memory
Hi, I see a strange effect which puzzles me. I have two AMD64 (~amd64) Systems. Both have 8Gb memory installed as reported by their BIOS as well as by lshw. One is a somewhat older Opteron, the other one a recent Phenom II. But the output of 'free -m' differs significantly On the Phenom II there a total of 7738 Mb but on the old Opteron there a total of 6477 Mb only. The 2.6.36 kernel is configured nearly identical (just a different SATA driver). Has anybody an idea where this comes from? Many thanks for a hint, Helmut.
[gentoo-user] ebuild creation (python-2.7) - please help
Hi,
after switching to Python-2.7 an ebuild of myself fails.
I'm trying to write an ebuild for dev-python/pyparsing-
My attemp fails with 'setup.py' not found.
The package is unpacked into
/var/tmp/portage/dev-python/pyparsing-/work/pyparsing-
This contains the subdirectories doc examples and src.
And the setup.py files is in src.
Many thanks for a hint,
Helmut.
