General :: Get A Fast Free Unix Native On A Mac Pro?
Oct 22, 2010
I am interested in running Linux on my Mac Pro (8-core, 24 GB RAM).
What are the main caveats one should expect? Can all hardware be used natively after booting, say Linux or FreebSD?
Does Solaris run on this type of machine?
My use case is mostly Mail, instant messaging, web browsing and network simulation (hence this machine) and I value interactivity under full system load the most. How is interactivity under full load in Linux? My experiences with Debian "lenny" showed delays when task switching of up to 1.5 seconds. May I should look at FreeBSD?

I installed centos 5.3 with last update in Virtualbox 3.06. Everything looks quite good except the unix time. It's very fast than normal. I even couldn't make ntpd work.
[Code]...
I also modified the menu.lst files as following: kernel /vmlinuz-2.6.18-164.el5 ro root=/dev/vg00/lv00 rhgb quiet divider=10 But it still dosen't work. how to sync the local time in the virtualbox? It looks like a bug in current kernel as other linux with newer kernel don't have such problem.

I want to set something up so I can have a pen drive and do all of the following:
1) Boot linux from the pen drive on systems that support usb boot devices.
2) boot from a CD that switches over to the usb drive and releases the cd (for systems that do not support USB booting)
3) Optionally run the same pendrive linux installation from windows
a) Huge preference for NO vmware or other emulation/virtualization environments
b) something like colinux or topoligilinux
c) big prefence for doing this with linux mint or at least ubuntu
d) bonus if I can do the windows part without admin priviledges on highly restricted systems like library computers
e) worst case scenario maybe could set it up in one of these ways
1) have cygwin and a seperate linux distro and just mount the home folder of one from the other - but prefer to not waste space duplicating applications etc.
2) I wanted to put a two and three here but I'm out of ideas.

Is there a native Linux application that can interface with mint.com? I like the website, but I would also like to have that information stored locally so I can view it anytime, even if I am not online. Also, is there anyway I can just bypass mint.com altogether and enter in all of my accounts directly and have it periodically update their information?

I installed Koala 9.10 with Wubi, and have liked it enough to give it a "native" installation on a partition. I've been looking around at forums, and it seems the most attractive way, with LVPM, hasn't been tested officially with 9.10, and I can't find a post of anyone that has.
So, my question is, does anyone know the best way to upgrade my install to its own partition? My drive currently has 2 primary partitions (main Windows Vista OS, and a recovery) and one extended with a logical drive. I don't know whether to try the LVPM method, or try to just uninstall Wubi and install 9.10 after from the Live CD. But, the reason I went the Wubi route in the first place was the install/Live CD would hang when I got to the screen with the options to check the install disk (I had previously checked the hash, and it was fine), proceed without changing disk, etc. I think that is a problem with the install getting confused with my multiple drives/card readers, and not being able to find the correct one. Wubi had a similar problem giving me something like "please insert disk into drive X:", and I would have to just click over and over, each time X changing from one drive letter/number to the next, until the install just continued when it found the right drive.

On my Acer laptop wit ATI Xpress 1100 I have a native resolution of 1280 x 800, and Linux Mint 8 (of the Ubuntu family) offers that resolution without a problem. However, a few days ago I connected my laptop to my TV, and since then the correct resolution setting has been LOST. It doesn't appear anymore in the Display settings and so I had to choose a lesser resolution - I am now looking at a less sharp screen! How can I delete it? I hope that I don't need to reinstall...

Installing 11.2 from KDE LiveCD on an IBM ThinkCenter with 3.2Gb CPU and 1Gb RAM. Ubuntu 9.04 on first two partitions. I go through the configuration, click to 'install': Install display bars remain blank. After 2-3 minutes, black screen with scroll of attempted installation pieces and the error message: "Respawning too fast. Disabled for 5 min." Freeze.
Other posts mention problem with init. But this is happening with the install so not able to address that. No apparent md5chksum for LiveCDs. No mention of this problem in installation help guide. Does anyone know how to deal with this? If you need more info, I will provide. Though it seems this is not an unusual problem when booting an installed system, there's no mention of it happening during installation.

In the old days of M$-DOS, there was the NCD (Norton Change Directory) utility. Anything of the sort in Linux?Explanatory note: you typed out the name of the directory you wanted to go to, that is, last element of the dir path.And you were, ipso facto, in that dir. If that was the only one by that name, good. When not, and if that wasn't the intended dir, you typed the same command again and you were in a second dir of that name. If this was the intended dir, good. And so on. It simply maintained a data base with the whole tree, and updated it when invoked from a newly created dir o by means of an option, NCD/R.

I've got a question on free disk space. I'm currently running CentOS 5.5 on in Xenserver virtual environment. We've had an issue with disk space. My question is as follows: - from a ssh connection i run df -h this gives the value of 90% used leaving me with 9GB. If I use system monitor via a VNC connection the free disk space value is 20GB free on the same volume. Which one is correct? I do use SNMP to monitor the same volume and should alert me when < 10% is free I know this works as I set the alert threshold to < 90% I get an alert.

I'm looking for a fast Linux distro to put on a USB key. The goal is to be able to boot in as few seconds as possible, with just enough to mount a hard drive and do some basic operations in there (bash would be enough).
I do need:
x86 and x86_64 support
EXT2/3 and NTFS mounting capabilities (read & write)
Networking support (/etc/network/ config is fine, no need for detection) Bash (another shell would also work, but I would have to modify some of my scripts I would prefer if I didn't to have to build these programs for the selected distro, but that's always an option. I do not need:
X, or any form of GUI
more languages (english is enough)
anything not mentioned
I don't care about the size on the USB key, but the bigger it is, the longer it will take to load. My research pointed me towards these distros, but I not sure which one to choose:
ttylinux
Tiny Core Linux
tomsrtbt (doesn't look maintained anymore)
I also found these tools I could use to build my own distro (as a last resort)

I've been using linux for a while (various distros) but somehow they dissapointed me. I know what I'm looking for, a lightweight, fast, minimalist but customizable enough, with no specific graphical environment, bleeding edge distro for a new laptop (used for studying and surfing internet), that hopefully works with my hardware.
I want to have the possibility to compile from source to make my own changes but also to install from binaries easily. I'm not a linux expert, not even an advanced user but I'm willing to learn anything to get my distro running so I'm not looking for a full out of the box distro. It would be great if this distro also had a good community.

I recently got an ASUS laptop with a Core i5 processor and an ATI VGA card. I would like to install a fast distro and keep my Win7 installed. [dual boot]. I hate Windows 7 because it boots really slow even on a 64-bit system like mine (they claim it's 60% faster, and it still takes about 2 minutes to boot). So I want a distro that boots really quick (in less than 25 seconds). Also, I need it to have the very latest drivers because my laptop is quite new, and I read that the same VGA card I have already has problems when running under Ubuntu. (Not sure though)
I like programming (Python and Processing), so I did lots of research and figured out that Fedora is pretty good for programmers (it has many programming languages and IDEs already configured in the system..no need to install anything!) + I think it's pretty secure since it is based on RedHat Linux + I read some stuff about Fedora 11 and their promise to boot in less than 20 seconds, donno about 12 though? is it true anyway?
On the other hand, some say that Fedora's package management is not very cool when compared to openSuse's decent package manager and system administration tools...etc. Linux Mint looks very elegant and it can run Ubuntu's packages [I suppose] so it's another possible choice too. CrunchBang is also really attractive and minimal, they say it's also quite lightweight..so that's another possible choice for me too
My questions are:
- Which of the above distros is the fastest when booting? This matters the most for me.
- Which one has better support for the most recent drivers? especially for laptops?
Is there any other distro that boots faster than the above distros (in less than 25 seconds on a Core i5) and still has good hardware support and security? I don't really care for the distro's appearance as long as it does the job.

I am trying to use the Linux Ramdisk y machine and followed the instructions oninux/Ramdisk/ramdisk.html to create a 4GB ramdisk (total memory is 8GB, linux 2.6.9)The issue is that it is taking me almost exactly the same time to read a 1GB file from ramdisk as it is from disk. I was expecting it to be atleast twice as fast.Has anyone encountered this before?

I had a memory stick problem over the weekend, and after correcting the problem, I decided to up grade from Linux Mint 9 to Linux Mint 10.
All video and sound functions worked properly prior to changing to Linux Mint 10. Now I can not get any sound out of the speakers, from a CD or a digital file, and a video goes at super fast speed with no sound. I am new the Linux world but learning fast. Data CD's work correctly both in reading and burning new.
