Imagine the noise the Linux-newbies would make when the apps installed to their $HOMEs fail to run at all after an upgrade because they're trying to reach incompatible versions of libraries that are installed globally.

Casao posted:The whole point is NOT global installations. How are most apps global installations under linux? Why on a "true" multiuser system is it so hard to get per-user applications. I want to install a few apps that should not in any way require admin access, yet I can't just "apt-get install" it... I have no idea why. rpm and dpkg support it, frontends such as apt-get/yum/up2date don't because of a lack of interest. Most people who have any interest in using a different flavor of software spend 20 minutes learning how to build it themselves. Of course, if you did fine some point-and-click facility to install within your homedir, you'd be upset that kde didn't know where your private copy of firefox was, or that you didn't want to have 10 copies of openssl libs on your system, or that linux used too much disk space.

Most people who have any interest in using a different flavor of software spend 20 minutes learning how to build it themselves. It's not just a lack of interest. Creating a commonly-usable, easy way to install programs as your normal user means that programs will be installed as your normal user. Because the program files wind up owned by the normal user account, random malware and security vulnerabilities would be able to exploit that and overwrite them, and misconfigured programs could trample over eachother; the situation winds up almost exactly the same as if the user were running as root all the time. The system should be setup such that normal operation cannot break it - in order to achieve this goal, software installation is elevated to a privileged operation and requires a password. The "correct" solution, of course, is something like an SELinux policy which allows certain programs (such as the package manager) to manipulate the whole filesystem, while normal day-to-day-use programs are restricted to only those files that they need to access. With a complete enough policy, the special rights assigned to UID 0 go away, because all sysadmin tasks are handled through roles. In practice, such a policy rapidly becomes unmaintainable, and the root user is a compromise that most people can easily live with. There is also the minor technical problem that many programs have various paths compiled-in, and the resulting packages cannot be installed to anywhere but / and still maintain full functionality, but presumably you could either fix the programs, or compile in recognizable placeholders and perform install-time binary patching to fix everything up.

Can anyone recommend an application that runs in cli mode without the need for X11 and can capture individual frames from a V4L source, in this case a Hauppauge HVR-950 USB tuner. I've been tasked with making a small appliance for a lab experiment that basically takes frames from a video feed of an experiment and makes them available via HTTP. I'd rather keep this headless and eliminate the need for X. Sorry if it's a dumb question. It's been about ten years since I last did anything with Linux in this capacity, and googling hasn't revealed much of interest. Edit: Bonus points if someone can recommend a solution which would stream video as well, but that is going way beyond the scope of my original project. I've looked up VLS and VLC, but I think both require X

Is there a way to make the Windows key function similarly to how it does in Windows? That is, no action is taken on key-down, but as soon as you depress another key, it becomes a Win+<key> combo. Alternatively, if you hit no other key, it registers as a Windows key keypress upon key-up. I've managed to get it to act as a modifier and as a regular key, but not as the sort of hybrid behavior I would like.

hello I just installed ubuntu on my new t61p. It is great and 98% of it 'just works'. The other 2% is being a real pain.jpg. Firstly: The Fn+X buttons on my laptop do great things, like let me enable/disable wireless, change brightness, suspend, bring up battery information etc. What the heck controls this? I thought it might be acpi but these events still happen when I disable the acpi daemon. Are they configurable or disable-able at all? Secondly: I just spent 3+ hours fiddling with twinview. How can I make it so that I can enable/disable screens without having to start X? I figured this would be doable using the metamode option, so I tried defining several metamodes: Option "MetaModes" "1920x1200,1920x1200; 1920x1200,NULL" Option "MetaModes" "DFP-0: 1920x1200, CRT-0: 1920x1200; DFP-0: 1920x1200, CRT: NULL" Option "MetaModes" "1920x1200,1920x1200; 1920x1200,NULL" Option "MetaModes" "1920x1200,1920x1200; 1920x1200; 1680x1450" edit: extra info however, the xlog (below) says "No metamodes defined" (line 615). So when I run xrandr all I get is a single mode: $ xrandr Screen 0: minimum 3840 x 1200, current 3840 x 1200, maximum 3840 x 1200 default connected 3840x1200+0+0 0mm x 0mm 3840x1200 50.0* anybody know what's going on? How do I define metamodes?  conf here and log here edit: server being funny paste is here adante fucked around with this message at 05:36 on Jun 21, 2008 |

I'm using the stock GNOME keyboard shortcuts in Ubuntu. I'm using Hardy at the moment, but it's been the same for the last few releases of Ubuntu/GNOME. By default it treats it purely as a modifier. In the past I've been able to change it to act as a standard key, although I forget how... xmodmap maybe? Something like that. I'm pretty sure this was the case back when I was using KDE and its bindings configuration, too.

Two questions, I've been running linux since 1993 and tried most popular distros over the years but never played with LVM or Virtualisation until now. I recently got my hands on a Dell poweredge SC440 server which I'd like to use to consolidate all the stuff I run here and keep a split between personal/development/toying around and general/backup/management stuff. Currently not sure whether to use LVM or not or whether to go with Xen or VMWare. Hardware I think I have covered, can get a second sc440 if needed and have 8gigs of ram and a old SCSI enclosure with 6 removable sata drive bays (3 x 2 drive USB/e-sata bridgeboards). So with 8 gig and 10 possible sata connections, should have more than sufficient memory/storage. Currently, I have CentOS 5.1 installed, mainly because it's been a while since I've run Red Hat and positive press. By default it setup a LVM for the drive it's installed on and after reading up on LVM it seems useful but not sure how it deals with removable drives/recovery. I don't mind being careful with volume groups and striping to ensure that I can remove drives if needed but in a disaster scenario will using LVM restrict what tools I can use to recover data? Xen comes as an install option with CentOS and seems easy enough to use but does it have any advantage over VMware server except it's licence? From my brief play, it seems to be restricted to what can be a guest OS (although still good range), installation of guest OS can be a pain, little virtual appliance support and seems to have performance issues if running from a file. Are there advantages to Xen that I've overlooked?

Does anyone else have similar issues to this? I've finally bothered to update Ubuntu again today, worth 250MBs of updates. With the update came Firefox 3 final. What I'm having is that Firefox (most used application), seems to lose focus of the address and search field at random. That's pretty annoying. What could it be? Also gently caress Ubuntu screwing with the xorg.conf on every goddamn update. --edit: Well, this was on my laptop and turns out that the loving updater hosed some more with my xorg.conf and changed the input driver for the touch pad from synaptics to mouse. Maybe that was the problem. Combat Pretzel fucked around with this message at 20:06 on Jun 22, 2008 |

What would be a torrent client that would allow me to have /home/share/ as the default folder and allowing me to select subfolders to place the files in while still seeding (video, audio etc). I've been running TorrentFlux but since it has users and can't handle placing the torrents anywhere except the user folder it doesn't work for me so well. Azureus can do this but the web interface isn't the greatest and its a bit heavy on my system which also runs an audio streaming service. Running Ubuntu on a P3 866 with 386mb. Edit: Or if there is a way to get Torrentflux to throw the files into /home/share/ by creating a user named "share" AND being able to sort the files into different folders that would be just fine. Haven't found anything that would this at the moment. Bensa fucked around with this message at 11:28 on Jun 23, 2008 |

Can anyone recommend a stripped down Linux distribution which includes V4L drivers in its basic kernel? I'm looking for the smallest footprint I can get, and I don't want gcc or anything installed. End result is that I want to be able to fit this stripped down distribution on a USB stick. I know there are several small USB-stick enabled distributions already, but they're all dolled up with fancy GUIs and apps that I don't need. I'm ready to do the work in cleaning up a more featured distribution to fit, but I'm just looking for recommendations first. Again, the only requirement is that V4L modules are present in the base kernel without any compilation necessary. Edit: I have to say, after using MacOS for the past half dozen plus years, coming back to Linux doesn't feel as awkward as I thought it would

Stupid question! According to the Xubuntu website:quote:Xubuntu uses the Xfce desktop environment, meaning that it will run fast while still delivering a user-friendly interface. Older computers feel lively again, while newer ones will run faster than ever before! Given this, why would someone choose Ubuntu over Xubuntu? What are you sacrificing for the added speed? Is it just that Xfce is really ugly?

No, it's just got less features / applications. KDE and Gnome are really more like mini operating systems of their own, in that they provide a large base of libraries + docks + window styles + etc, so lots of applications and utilities and so forth are built on top of them. In other words, Xfce != KDE or Gnome; it is not at the same level, so asking "if X is faster why does anyone use Y?" doesn't make sense.

Actually I think it looks pretty nice. It's less well-documented, so if you find out you install it and your volume button or power management or something don't work, it's harder to find help. You don't get Nautilus (you can still run it, but it automatically starts big chunks of Gnome along with it which defeats the purpose of a lightweight desktop). The Xfce file manager, Thunar, doesn't have as many features - I don't know the details, but I'd guess it's harder to browse Windows network shares and things like that. I actually think Xfce looks really nice, and I like the fact there's not as much crap I'll never used stuffed into it.

Xfce is great. It has a lot nice touches that I miss when I don't get to use it. I use Rox Filer (http://roscidus.com/desktop/ROX-Filer) instead of Thunar. It is much more powerful than it looks.

Anyone have any suggestions for really lovely hardware? Specs: Pentium III - Dual processors 512 MB RAM 18 GB HDD CD-ROM ONLY (DVD is NOT supported, neither is USB booting) lovely ATI Mach What happened was I had the box setup running RH9 using YUM to update. Everything was fine until my boss demanded a file server be setup ASAP and use the current hardware. I wasn't around that day so he gave the job to another worker who has no experience with linux and simply ran commands (he found on the internet) while logged into root. I came back and the machine wouldn't boot properly and was basically totally hosed. We have backups so we are okay. Only things needed are: VNC, SSH and KDE. It needs a GUI simply because a certain software package we use (theoretical chemistry calculations) only works in linux (actual req. say RH 6.2 or greater, Mandrake 7.0 or greater, SuSE 6.3 or greater, Generic Linux [kernel 2.2, XFree86 3.3, glibc 2.1]). Though the software is dated it has one feature that out does all the new web based setup we have so we would like to keep it around. I'd rather not run RH9 anymore as it is dated fairly badly so any suggestions towards something minimal would be appreciated. -- Edit: KDE is preferred over GNOME because of how the program visualizes and allows for multiple VNC sessions by different users using the same program. It is restricted to local so vnc security isn't a huge issue.

Last I tried Arch Linux it was pretty minimal and had a really fast package manager. Pretty slick distro. Also, an Ubuntu server installation would be super minimal but I believe adding the desktop to that would bring back all the bloat you're trying to avoid anyways.

If we didn't need a GUI it would be nice but the part that worries me is I have no clue how this is going to behave on other distros other than RH9. The machine is drat well aged and replacement just won't happen due to frugal bosses.

If you want a new os, your best bets would probably be CentOS and Fedora, as they'd probably be the closest to RH9 from new OS's. I'd be concerned though, because IIRC, RH9 is a 2.4 kernel system, and any of these newer systems are 2.6, You could try setting them up in VM's first and then seeing if this program of yours will run on them.

Registration key fuckery makes that pretty impossible. It is generally a pain in the rear end anyway. Tried Fedora Core 5 (old discs I had lying around) but there seemed to be an issue with the video drivers (ATI bullshit) giving blank screen upon starting x. Tried a bunch of possible fixes and no luck. Worst part of it is the drat CD drive. Each takes like 5-6 CD's where if it was a DVD you would only have a single disc. Tried Arch and it didn't seem to want to setup very nicely (random freezing during setup (not just hanging, full on freezing that left for hours would do nothing) and generally not being cooperative. Might just bite the bullet and try Fedora 9 and see if it will play nice.

Do you need local GUI, or just GUI via VNC? Remember that a headless server can run remote VNC sessions... so if possible, save your memory by not running X on the server's display. Also be sure your app works on a more recent distribution... if it's old enough to list kernel 2.2 and glibc 2.1 as its requirements, a 2.6 kernel and glibc 2.5 might piss it off. Assuming it's happy with modern distros, I'd probably try Debian. A basic install can be done from one CD, and then you can add KDE and stuff through apt. Fedora 9 is going to be tight.
