Get a newer version of grep. I have GNU grep 2.5.1 and it has the following options:

code:

Context control:
  -B, --before-context=NUM  print NUM lines of leading context
  -A, --after-context=NUM   print NUM lines of trailing context
  -C, --context=NUM         print NUM lines of output context
  -NUM                      same as --context=NUM

So you would be looking for -C.

Depends on what desktop you're using. If you're using KDE, you can check kde-look.org for plasmoids you like. If you're using gnome or XFCE you can use adesklets or gdesklets.

Nice. It also occurred to me I could just do this in three separate lines:

code:

sed -i 's/DR//'  scrape.txt
sed -i 's/B//'   scrape.txt
sed -i 's/OTH//' scrape.txt

No love for SED

Try running your sed with "" quotes instead of ''. I know if you're using variables in sed, if you use '' it won't work ($myvar would be read as "$myvar" instead of whatever $myvar equals).

Thoom: Jan 12, 2004; LUIGI SMASH!

I just installed the Ubuntu Lucid RC on my new laptop via a rather convoluted process, as the install CD just gave me a black screen. I started by installing Intrepid, then upgrading to Jaunty/Karmic/Lucid via the update manager.

First of all, is this going to screw me over somehow? I know I'm missing GRUB2 and stuck with ext3 as a filesystem, but is that actually worth worrying about?

Second, due to these repeated release upgrades, I have 4 different kernels in my /boot directory. Since the Lucid kernel (2.6.32-21-generic) seems to work, is it safe to simply delete the older ones and run update-grub to clean up my boot menu, or is there some preferred way to do this via automated tools?

You should be able to use an alternate install CD to install without the GUI. That sounds like an X issue in the Live CD that obviously isn't present in the full on system, so bypassing X in the install should get you up to speed with all the spiffy new stuff.

8.10 was the other CD I had handy, and it worked so I didn't feel like wasting time downloading/burning CDs for 9.04/9.10 to test. Actually, when I upgraded to 9.10, I had the same black screen issue, but I was able to solve it by rebooting in recovery mode and adding a few lines to my xorg.conf (which you wouldn't be able to do on a Live CD).

I'll give the alternate-install a shot, since my gradual upgrade path seems to have hosed my synaptics driver pretty badly.

So I am trying to get some form of linux, ANY form, onto my Thinkpad X201.

I've narrowed down the issue to probably being due to this integrated graphics card

I had at least gotten a mostly working setup via the 9.04 alternative install... I had a working system, except for one tiny problem: The system froze shortly 30 seconds after login, without fail. So, it was completely unusable unless I stayed in text only mode....

I looked around, and the issue apparently was with my graphics card on the X201.

Here is the thinkwiki page for the laptop and the graphics card:
http://www.thinkwiki.org/wiki/Category:X201
http://www.thinkwiki.org/wiki/Intel_HD_Graphics

I had been attempting to manually update the kernel to 2.6.33 using .debs I found online - no luck.

Someone suggested I try the newer version of Ubuntu, so I downloaded the Ubuntu 10.04 RC alt install CD... it installed fine, but when it starts up, it now just goes to a black screen. I can't even go into text only mode like the 9.04 beta was letting me

I am very desperate, I am _very_ close to sending this laptop back to Lenovo, if anyone has any suggestions on how to get a working Ubuntu (or any other distro) install going on an X201, please share any details you can remember!

i would try using arch linux (http://www.archlinux.org/) since arch just updated to the 2.6.33 kernel in it's stable repositories. I've never had issues with it for just about anything. Just remember that arch has a little different mindset than most linux distributions where it tries to centralize loading daemons and whatnot. Also AUR is your friend when you need packages installed.

Do you see anything at all, or is it just totally black when it boots?

If it's just black it sounds like the framebuffer isn't being initialized. I don't remember the exact syntax but I would suggest changing the kernel options to not use a framebuffer and also blacklist the framebuffer module.

Does the server distribution initialize a framebuffer by default? If not you could install that and then install the desktop packages.

Someone suggested to me I try disabling KMS... which I have no clue how to do :/ (especially since it's booting to a blank screen...)

It's totally black... like it mentions grub then shows a blinking "_" then black screen. If arch doesn't work I'll try the server install I guess, I'd like to try disabling KMS as well if I can figure out how...

i would definitely try downloading a torrent, on their site they recommend it since they don't have a heck of a lot of bandwidth for iso's.

Newer versions of Xorg require KMS for the intel drivers anyway, so it might not work.

I think you can try disabling it by adding i915.modeset=0 to the kernel line in grub.

Arch is great and being up to date adds support for all kinds of new hardware, but make sure to follow the Beginner's Guide if it's your first time around, because you'll basically be setting the system up from scratch, so can be a little intimidating.

If you find it too intimidating, you could give Chakra a spin. It's basically just arch with KDE installed and a GUI installer.

There's also ArchBang which is pretty much is the same thing with OpenBox instead, but the project was started this year and thus is not as mature and polished as Chakra yet.

Chakra's KDE4 theme looks pretty drat nice, by the way. Haven't been able to stand KDE ever since checking it out on some of the first Knoppix versions, but it seems to have improved a lot (well, duh).

When it boots, hit whatever key to get to the boot menu, then add i915.modeset=0 to the kernel line in grub.

This will disable KMS for this session, then do whatever that ubuntu guide said to make it default for newer sessions.

Yeah, this worked, I can boot and start to install the 10.04 RC cd I made, however the final release CD I have boots to a black screen, no way to edit boot options.

I'm gonna just settle for the RC at this point and hope someone else has the same error, or maybe wait a couple weeks til they update the Fedora USB creator and try that... there shouldn't be any major issues from running the RC right?

Edit: If I do an upgrade from the RC to the final release, will it save my edited grub or hose it and thus brick the machine?

If you run 'sudo apt-get dist-upgrade' you'll be off the RC and onto the final. And in fact 'sudo apt-get upgrade' will do. I just checked on my RC machine, only 60 packages, about 100 MB, to update.

I just upgraded my media server with some bigger harddrives and want to make a better backup system. Before I was CRONing a job that would TAR up every file in my media directories into respective TAR files.

That sucks tho, because it just keeps backing up the same poo poo over and over again.

What can I do to like, only add new files to the backups? I dont mind strait up copying the files from one directory to a directory on a backup HDD if I can have the backup script only copy over new files.

You're looking for an 'incremental' backup. Use the -u option to update the tarball with newer files

Watch out, as --update doesn't remove old versions. Technically, you'd want that with backups, but it also means your tarball will grow and grow. For more robust incremental backups you should use something like rsnapshot. Even if you use it for something as simple as only keeping two previous versions it can still be a lifesaver.
