And, my floppy drive does not show up in my Xfce 4.8 file manager, before or after the modprobe. Do I need to yum something? Did I miss a driver? I can manually mount disks. Check out udisks.

Gkrellm is the easier to setup, but uses more cpu, conky is harder to config but in my IMHO worth the time and effort. Conky does come with a basic script to start and there are many on the internet if you google conky scripts. The scripts are read from /etc/conky/conky.conf Have fun Alex Thank you!
fastest boot time laptop sl 6.0
hi, This had been bugging me since I installed sl6, so a few weeks I sat down and tested a few things. Hopefully it will help someone. The problem: my corporate laptop (dell latitude e6500, which by the way, works great with sl 6.0), took a while to cold boot. Pressing escape to see the console messages showed that the cups daemon was started, and after about 15 seconds, acpid would start and then the rest of the daemons and I would be greeted by the logon screen. This would not happen in case of a reboot, by the way. Hibernating, although functional, takes longer than boot, so why bother :( I modified /etc/init.d/cups, changing the chkconfig 2345 25 10 line to chkconfig 2345 95 10. Then chkconfig cups off and chkconfig cups on to recreate the symlinks, shutdown and start. So now cups starts quite late in the boot sequence, but that does not matter at all as long as it starts after syslog and local_fs. Printing works as usual after this change. I am very happy to say my laptop has been very fast to boot since this little change. These are the little things that matter. -- Groeten, natxo
LabPlot
Does anyone have a working copy and/or RPM of LabPlot for RHEL 6 (SL 6) x86-64? URL: http://labplot.sourceforge.net/ In the past, I have built this application from source. With SL 6, I get the following message from configure: checking for KDE... configure: error: in the prefix, you've chosen, are no KDE headers installed. This will fail. So, check this please and use another prefix! despite having loaded all the SL KDE development packages, having /usr/lib64/kde4 and /usr/include/kde4 present. Any assistance would be appreciated.

SL 6 IA-32 and X86-64 polymorphism
I found on the web: Unlike Debian based distributions, Red Hat and distributions based on it organize lib directories in a way that lets you install a 32 bit package of .so files on an x86_64 system without any conflict with the 64 bit build of the same package, which may also be installed. AND: The Debian system dynamic library linker has been modified so that when a 32-bit application requests access to a library, Debian provides the 32-bit version of the library if it is available instead of the normal 64-bit version that the native applications require. This works if the ia32 packages which provide a sub-set of standard Debian libraries compiled in 32-bit mode have been installed. (NB: I am not using a Debian distro, but the SL 6 RHEL 6 distro. The quote is for clarity.) End quote. Unfortunately, this does not always seem to be the case in direct practical experience. Two questions: 1. How to install the SL6 release so that the System - Administration - Add/Remove Software will list both the 64 bit and 32 bit libraries? I have tried sl-release-6.0-6.0.1.i686.rpm and this does not cause these library choices to be displayed. I suspect this is because from the sl.repo file, the stanza name=Scientific Linux $releasever - $basearch always puts the actual base kernel ISA into the $basearch, so only X86_64 appears. I tried to make a separate repo file that would force the IA-32 libraries to be listed, and although I enabled the new repo using System - Software Sources in the Add/Remove Software application, no such library RPMs appeared. 2. Many packages that must be built from source rely upon configure and for various reasons, paths such as /usr/lib , not /usr/lib64 that is the X86-64 path, appear. This is an issue with appropriate scope specific polymorphism. Will the following idea address this issue? Two unique paths for libraries and include files: foo32 and foo64 with foo being the appropriate path identifier. At the actual time when a decision as to which foo to use, set foo to either foo32 or foo64 but let the application (e.g., configure and the files needed for configure to configure) only find foo . Thus /lib could be either /lib32 or /lib64 depending upon whether a 32 or 64 bit application was needed, etc. This is still much simpler than a chroot mechanism of keeping two identical operating systems and application environments on the same machine, one IA-32 and the other X86-64. Obviously, utilities such as ld (mentioned in a Debian context above) must be aware of the differences, as must compilers when creating appropriate object or executable file internal headers.

At TRIUMF we have the need to cross-compile 32-bit executables on 64-bit machines. This is for two reasons: we have some dedicated hardware that only runs 32-bit executables (VME processors, etc) but is too slow and does not have enough memory to support a self-hosting build environement (so we have to cross-compile); and we have some software that uses 32-bit-only 3rd party proprietary libraries. So I am very familiar with the questions you asked, but only for SL5. We are just starting to use SL6, but so far everything seems to be the same. 1) out of the box, yum list shows both 32-bit and 64-bit packages. (From SL5 to SL6, 32-bit packages changed from .i386 to .i686 and tripped up some sysinstall scripts). Not all existing 32-bit packages are included into the 64-bit distribution. To install them, you can add the 32-bit repo to your system (but be ready to handle conflicts!) Some 32-bit packages will conflict with same-named 64-bit packages, if really required, one can force their installation by using rpm -vh --install --no-deps (but if you break your system, you get to keep both pieces). Some 32-bit packages are throughfully supplied through the compat packages. If not, move to question 2: 2) yes, very often building of external packages from source becomes confused by /usr/lib /usr/lib64 etc. This is where autotools becomes a bother instead of helper. Things like pkg-config, foo-config also work against us as they are broken by design for the case when 32-bit or 64-bit libraries need to be selected as needed. The general trend seems to be towards things only work on the developer's laptop and if stuff does not work for you it is because your machine is different from my laptop and tough luck with it. -- Konstantin Olchanski Data Acquisition Systems: The Bytes Must Flow!
