I'm staring at what happened under RHEL 5.x with autofs updates, bind versus bind97, openldap versus openldap24, subversion updates, and samba3x updates with significant feature additions. The "security updates" are not enough to try and keep current with significant feature changes. And as long as the changes are locked off in the minor release change number by a refusal to expose the system to the "5.0 through 5.5 reales", rather than updating to 5.6, they'll be unavailable. This happens _every time_ there's a new point release, and I'm convinced from painful experience that keeping to the "5x" repositories rather than the active and current channel for upgrades introduces genuinely painful system skew. In my opeinion and experience, it's a support rathole and contributes to developers and admins having to maintain their own, personal sets of drivers and binaries and libraries and destablilizing the whole mess. It certainly occurred with the upgrade from 5.5 and 5.6, I was able to throw away entire sets of poorly integrated user-built tools and replace them with supportable and better configured system tools from the upgrade.
Need KVM HD settings advice
Hi All, I am confused. I am getting to the point were I am about to set up my first KVM server. My fist adventure will be to migrate an XP guest I currently have running on my old server under Virtual Box 3.2.12. What I need help with is getting the optimum performance settings while converting over my old hard (virtual) drive. This is what I have gathered from these parts as to the best settings: - controller: virtio - kvm option: cache=none - qcow2 disk format with metadata preallocation - create your disk image with: qemu-img create -f qcow2 -o \ size=400,preallocation=metadata vdisk.img So far so good. Now what I am concerned about is retaining the optimum settings from a converted hard drive. Also gathered from these parts is the best way to convert the hard drive: qemu-img convert -f vdi oldImage.vdi -O qcow2 newImage.qcow I am afraid I will loose all the optimum settings. And, I am vague how a *.qcow file/drive and a *.img file/drive relate. Many thanks, -T

Btw, once you enable real-time configuration, you can do lots of magic with your touchpad, for example this snippet (works on modern systems but haven't checked on SL6 - but probably it should work) - tweaks touchpad so that double-finger tap works as middle button that's always missing on touchpads (of course, touchpad must supports multitouch) and also disables touchpad while you are typing text, so it won't be sending annoying commands during that. syndaemon -i 1 -d -K && xinput set-int-prop \"SynPS/2 Synaptics TouchPad\" \"Synaptics Two-Finger Pressure\" 32 10 &","0","*") It's kind of a magic so please don't ask me how it works, I have no idea :) It just does! -- Vladimir

It will create problems if you switch configuration if you create full-fledged xorg.conf; for example video card ID on PCI bus creates problem, and video card driver. However good thing is, you don't have to create xorg.conf; modern xorg supports small snippets of config files in which you can tweak only some part of config, and letting everything else to be autoconfigured. Sadly, this doesn't work for some stuff like video (if you have to set gamma, you have to put all sections like video card - display - etc), but it works perfectly for input devices. So, it's best to be without xorg.conf at all, if your system can handle it (if you install nvidia binary drivers, you probably must have that file :( ) Here lies the trouble, however, as SL6 uses Xorg 7.4 which doesn't support udev-based configuration (it appeared in Xorg 8 and higher) or config snippets from /etc/X11/xorg.conf.d; it uses older method of hal-based configuration with config snippets from .fdi files. Check out this page, here you can find exact solution which should work in SL6.0: http://en.gentoo-wiki.com/wiki/Synaptics_Touchpad/Xorg_7.3 (of course, skip kernel & X11 compiling part :) So, just create .fdi and customize it with options from manpage to your liking, you can enable synclient real-time configuration, too. You won't have to touch anything else or xorg.conf and this file won't interfere with systems that don't have touchpads at all. This should answer your second question, too. > Question 3: Can the touchpad sometimes interfere with the use of the > mouse? If so, how to minimize interference. the [replacement] mouse I > use may not be the right quality? Seems unlikely, I'd suspect faulty mouse, but can never be sure..

Thank you Pat and Bluejay for replying. Late last week, I found the culprit. It was the "cpuspeed".

I ended up making sure my kickstart script does not install it (basically added a "-cpuspeed" line to "%packages"), and it works much better now. I do like the idea of video-recording the screen, I have never tried that before (a lot of photographing the screen to capture items, but never tried video-recording it, will have to try that for the next problem). thanks, Paul On 09/19/2011 02:50 PM, Bluejay Adametz wrote: SCROLLLOCK should let you use PageUP to look at the text that went zooming past to see if anything interesting is afoot.

momentarily disabling synaptic touchpad
Hi, I have SL 6.0 installed on a Seagate FreeAgent GoFlex USB drive, which I use on various laptops (and desktops). The touchpad is so sensitive on some machines and I would like to disable it. At the same time, the attached mouse seems to be selectively responsive, notably its left button. Looking through the docs etc,a synaptics input driver has been installed, but the corresponding xorg.conf file is not in place for me to modify. (From a separate thread on nVidia, creating this file is NOT automatic in SL 6.) Question 1: If I create the xorg.conf file, would that later create problems for me when I switch to other machines--legacy or recent? I would not want some of the clashes (no/incorrect video, etc.) I experienced with SL 52 on USB sticks. Question 2: if synaptics driver is already installed, is it possible to have the fine control and features alluded to in the manual page (synaptics(4))? if so, how?The options in System->Preferences->Mouse->Touchpad are NOT helpful. Question 3: Can the touchpad sometimes interfere with the use of the mouse? If so, how to minimize interference. the [replacement] mouse I use may not be the right quality? Any help would be appreciated.

However, if I select an option with a GUI (like "Virtualization"), then I run into this problem. Any suggestions on what to check? thanks, Paul Jochum paul.jochum @ alcatel-lucent.com Hi Paul, This one sounds tough. I'm not too sure I know how troubleshoot this one. but I have a few guesses. If I were to guess, I'd aim towards plymoth simply because, like the system logger, it starts early in the boot process, but it operates a bit differently when an X server is installed. You might try removingrhgbfrom the kernel boot line (in grub itself or /boot/grub/menu.lst) in the more massive install and see if that helps. You could also try adding vga=791 to the kernel boot line and see if that gets you anywhere. Removingquietfrom the boot line has sometimes provided hints where the system hangs at boot (though this was mostly back in the early days of Linux wireless where the kernel would hickup a bit when those modules got loaded). Sadly with it failing so early in the boot process the VTTYs wont be setup yet, so its a bit hard to diagnose the problem. I've found NUMLOCK and CAPSLOCK to be helpful in seeing if the system has locked up (these days ), and SCROLLLOCK should let you use PageUP to look at the text that went zooming past to see if anything interesting is afoot. Odds are I'm on the completely wrong track here, but this is at least some place to start. Pat -- Pat Riehecky Scientific Linux Developer

A small matter of Nvidia/ATI, Mozilla, and OpenOffice. For Nvidia, ATI, or other proprietary drivers available from the vendor for Linux, I use the proprietary X windows driver. In all current cases on any machine with which I have to work (including those equipped with Nvidia GPUs for high performance computing, such as our current latest compute engine running SL 6.x *EXCEPT* for the kernel in which we use the latest production kernel that allows special drivers -- such as those needed for the Infiniband interfaces on our nodes -- to function), the Nvidia package from Nvidia that builds the appropriate kernel device drivers for X windows does work. Moreover, this adds all (or almost all) control over the functionality built into the hardware by the vendor. Note that on some of our machines (including my office workstation that has USB 3 interfaces), we deviate from SL 6x (RHEL 6) in terms of the kernel as I just mentioned. Thus far, for the hardware we have, both the Nvidia and ATI proprietary X windows drives seem to work -- requiring a rebuild whenever we change kernels. For the Mozilla suite (Firefox, Thunderbird/Lightning, SeaMonkey), I personally use and prefer the latest production release from Mozilla. This means that I do not use the stock SL (RHEL) RPMs from the install or update mechanisms, and, as root, I do use the internal update mechanism from Mozilla. I have found that Mozilla tracks security issues with a faster response time than the distributions seem to do (this may be a matter of opinion). I also upgrade to the latest pr
