Ularg: Mar 2, 2010; Just tell me I'm exotic.

So I have this old Sempron 1.7GHz PC with Ubuntu 9.04 which I have a use for, and I now have this new PC that I put XP Pro on and going to add new HDDs / Partition to boot Ubuntu 9.10 or another version of linux.

Now, as someone who is a relative nooby wanting to learn more about other operating systems, I am wondering what is something to do to help learn linux more, especially ubuntu (or any other that you would rather suggest).

At one point I mentioned to a friend of mine that running off a Minecraft or Garry's Mod server would be something I'd like doing (And I already had SRCDS set up for Windows XP), but he advised against it until I learn the operating system / wine / other stuff.

So what do you suggest I do to help learn more about what I can do in general.

If you want a game server and it has a native server binary, just run it! Don't beat your head against the wall trying to learn something you don't care about. Run whatever you want, see how bad you gently caress it up, then reinstall because you don't have any important data on that partition. Eventually you'll learn how to fix or prevent your mistakes and you'll feel like a wizard until you meet someone else in person that does it better.

That's how I learned, anyway.

there is a native linux steam server binary for that kind of thing. For learning linux there's many ways to approach it. You could start building a linux server to start learning the server side of linux. You could install something like arch linux to get an idea of how to configure linux and set linux up from a command line. If all else fails, start looking at different programs to try and use to see which ones you like. Or you could try running different games on wine and see how they run.

Really, learning linux is about seeing what options are out there and seeing what fits your needs best. I'd suggest trying fedora, arch, suse, and a couple other distros that strike your fancy because each one has a view on how the linux operating system should run and it's interesting to see how they approach a completely open source operating system.

Hard thing about 'learning Linux' is that you need a goal in mind. You can't just install it and then hope for the best. You need a specific goal in mind. Install a web server and get some simple pages going, set up Samba to share some files, get a game server going, etc. If you're really brave, your goal can be to use it as your primary system. Use it for web browsing, chatting, mail, etc. When something doesn't act like you want it to, try and fix it.

BTW, not really directed at anybody in particular, just my experience with learning Linux. And Solaris. And LDAP. And NIS. And Kerberos. And etc etc etc.

Ubuntu is the byproduct of some sort of crazy digital gentrification, that's not to say it's bad or somehow limited, but in much the same way as Windows or OS X you don't really need to see what's going on under the hood anymore. You can try a distribution like Slackware, but keep in mind you'll be stumped from the moment you boot the CD, since it dumps you straight into the shell, and you're left to your own devices for partitioning. Just getting into X requires extra effort, assuming you've gotten that far. I suggest you install GNOME slackbuild because you're used to it, but for extra credit give fluxbox a shot (do a full install, switch between them with xwmconfig) to see how the real hackers roll.

There's an enormous amount of concepts you can skim really badly just to get things working but it's still essential, especially just shell concepts in general, POSIX permissions, vi, grep, gcc, too much to list.

I'm a linux newb and I just started messing around with arch again and I'm really enjoying it. I was just wondering a few things though.

-Are there any linux equivalents to RMClock for windows? It's a program that allows you to undervolt your processor. I'm already using cpufrequtils to get the clock speed to adjust.

-Are there any simple paint-like programs? I don't need gimp or anything, just somewhere where I can just maybe add some text and arrows.

-Also, is there a simple way to change tray icons? I'm on openbox if that matters

Unless you *really* need features from a newer kernel, just use whatever is suggested by the update manager.

Being that the current kernel he's on just plain doesn't work, it might not be a bad idea to compile it himself.

@GregNorc:
I'll go with the old way back when I used gentoo. Download the sources you want, extract them to /usr/src/, cd to the folder, make menuconfig, set the options you need, make, sudo make modules_install, then cp /usr/src/yourlinuxkernel/arch/i386/boot/bzImage /boot/grub/whateveryouwanttocallit.

Then just edit grub to add an option to boot with the new kernel.

This is pretty vague, but it's all just from memory. You'll need some trial and error to figure out what you need. It might be a good idea to try to find the config that ubuntu uses for their kernels and go from there.

Yeah, sudo apt-get dist-upgrade should pull the latest kernel, along with everything else. If you're weird and don't want to update any other packages, if you just install 'linux-generic' and 'linux-headers-generic' you'll get the latest kernel.

On my 9.10 box I'm currently getting 2.6.31-20. On a 9.04 box the latest looks to be 2.6.28-18. hth

And the latest stable on kernel.org is 2.6.33.

What I'm saying is that if his hardware isn't supported or is unstable on the latest kernel in ubuntu he's gonna need some other source for the kernel. Either an unstable repo (which I don't know any) or compile it himself from source.

There were some major changes in the intel driver between .32 and .33, so it could be a good idea to try that kernel.

OK, I wasn't sure if he'd run any upgrades or not. First step is get Ubuntu's latest kernel, and step to can be the PPA for kernels.

Now, onto my problem!

I've got a multi-monitor setup, with a monitor above my main monitor. I'm also running Gnome, with a toolbar on the top of my main monitor. For a maximized window on that screen, and for some other windows, the windows open up against the top of the screen, not against the top of the toolbar, like they would if I didn't have a monitor above the main. Right now my dirty hack is to use the 'hide toolbar' option to get it to slide to the side, then I can touch my menu bar.

This almost isn't even a problem because I don't maximize things on that screen, and for most things I can right click on the window's icon and choose move, but that doesn't work for rdesktop, so I'm stuck with my loving rdesktop windows humping the top of my screen, immovable.

Basically, my particular processor (i5) has an integrated graphics unit that apparently needs 2.6.33, I found a tutorial online to get the .debs needed and installed.

The other thing is apparently I need to make sure that I have the Intel Xorg driver 2.10 or newer.

Running "apt-cache search xorg | grep intel" brings up an entry titled

"xserver-xorg-video-intel", but when I went to run it, apt told me I'm at the latest version.

I know my kernel is actually higher than the stock Ubuntu 9.04 (2.6.33), so I'm worried that what Ubuntu considers "current" is not actually the latest driver... however it's not mentioning a verson number, if anyone knows how I can verify I'm running Intel Xorg driver 2.10 or higher, I'd appreciate it, I wanna try and do both before restarting.

Thanks for all the help so far BTW

aptitude show xserver-xorg-video-intel

Also, why are you running 9.04? Especially since you're having bleeding edge hardware problems, I'd think the latest distro would be the best idea. Hell, the 10.04 RC is out, give that a try.

Are there some good tricks for having "preset" screens in the terminal?

We have a bunch of servers, and once in a while they need restarting, which annoys the hell outta me as I usually have like 10 screens open in various directories each with some terminal history ready so I can get my work done.

Like, I'd like a screen preset to be 4 subscreens in a specific dir, perhaps as a certain user, etc. Is that easy to do somehow? I can't really find anything in the man.

Even 10.04 only uses 2.6.32, figured it was better to upgrade the older, stable versions kernel.

New fedora uses 2.6.33 but the stable release isn't til mid may.

If this doesn't work, I will check out arch, thanks for the suggestion.

Edit:

So I got the source for the driver, but when I go to run ./config it says:

It had given a couple other errors but they were fixed by installing the relevant software. However, there is no package called "x11"... I found one called x11-common, but apt says it's installed and at the current version.

Do I need to install something else? Or do I need to do something with XORG_FLAGS, I have no clue what that's talking about, and google isn't helping much... plus I've got a feeling if I just install some random package it'll fix the issue, there were a couple similar messages that were solved by running apt-get install (name of missing package) and by installing build-essential.

You need the relevant -dev packages.

I'm just getting back into Ubuntu after a couple year hiatus. Anyhow, I've gotten back into the swing of things again, with just a couple of questions:

How do I go about customizing Gnome? I found alot of sites, but they all seem outdated, Or I'm just not looking hard enough. Anyone know of any good sites with themes+wall papers? Thanks.

Also, secondary, I don't know if anyone here will know the answer, but I'm running 9.10 and I have catalyst 10.3 drivers installed for my 5770. When I run Unigine Engine benchmark in windowed mode, it works fine, but in fullscreen mode, it flickers alot with what seems like corrupted images, different colors and whatnot.

Also recommended music/video players?

Edit: Also, when I go into any Terminal (Cntl+Alt F1-6), its just a bunch of multi colored blocks. I assume it's my video driver (since it worked before I installed 10.3). Any ideas on that? I'm slightly confused...

Anyone here know sed?

I'm scraping some command output from a set of cisco routers & diffing the results against a baseline file to get deviations. Trouble is that the line I want to compare has some pertinent values that change and some non pertinent ones. From what I've found thus far it seems that sed would be a good tool to substitute a constant character for the non pertinent changes.

I'm not really sure how to nest these three 'or' statements together. I've seen examples of (), {}, and [] for nesting multiple statements together in sed. None of them have worked for me. Any suggestions?

sed s/(BDR||DR||DROTH)/./ scrape.txt>scrape-parsed.txt

For anyone that knows cisco routing, what I'm trying to grab is 'sh ip ospf int brief' to track ospf costing changes. I'm already running rancid; but I need to track ospf cost deviations from baseline on a daily basis. Circuits get costed high when a vendor does schedules maintenance, but often no one remembers to change them back later.

Via grep, egrep, and grep -v I've been able to trim (there's other parsing prior to scrape.txt to remove login banners, command entry, and other stuff) the output down to this:

code:

Se6/0        1     0               1.1.1.1/30   	100   P2P   1/1
Gi0/2        1     0               2.2.2.2/30  		20    BDR   1/1
Lo1          1     0               3.3.3.3/32   	1     LOOP  0/0

I'm interested in tracking the current cost number via diff against a known good set of output stored in another file. The thing is the state also changes sometimes which will create the appearance of a line vs line diff where cost has not changed. I'm hoping to use sed to delete the state values or change them to a constant character to avoid this.
