Hey guys, total newbie to Linux I just installed Ubuntu loving it so far, only I'm having one issue, my laptop is plugged into a bigger monitor. Now I want to be able to close my laptop and have it just display on my big monitor. I can make it say it only displays on the big monitor but I cant figure out how to make it so I can close my laptop lid and it doesn't go into hibernate/shutdown/blank screen. Is it possible?

I like to shut my lid and put my xbox on top of it to save space on my desk, and having to keep my laptop open is becoming a hassle, tried googling the issue but came up with nothing.

System -> Preferences -> Power Management -> "When laptop lid is closed:"

That's in "classic" gnome, i'm not sure if they totally rearranged the menus in Unity or not.

Yeah in that option it only gives me the option to hibernate/blankscreen/ or shutdown. So no matter what when I close the lid my computer goes into shutdown mode and no longer displays on my big monitor

Fixed that like this years ago on a 10-yr old Toshiba: added Option "MonitorLayOut" "CRT,LFP" to the "Device" Section of XF86Config (now xorg.conf) in /etc/X11/. That made X use the external screen only - doesn't matter whether it's actually a CRT of an LCD - and somehow circumvented all standby behaviour when clicking the laptop's lid fully closed.

I don't know why the latter fixed that, though. May just have been lucky, given the limited support for power management at the time. I could still use the manual apm commands too. Give it a try, can't really hurt. If you end up with a blank screen (unlikely), escape X with Ctrl+Alt+F* to a runlevel 3 console or end it with Ctrl+Alt+Backspace if you must.

I did a motherboard swap in my server (Ubuntu 10.10 32b), and I'm not getting the improved performance I'm after.

I went from an Athlon XP 2600+, SIS 748(or something) with 1GB of ram to a Core2Duo E6750 dual core with an Intel P35 chipset and 4GB of DDR3.

Now apart form a small udev annoyance it booted up flawlessly.

I did a small performance test:

time echo "scale=5000; 4*a(1)" | bc -l -q ; cat /proc/cpuinfo | grep "model name"; cat /proc/meminfo | grep MemTotal

With the following results:

old system posted:

real 0m56.586s
user 0m56.340s
sys 0m0.008s
model name : AMD Athlon(tm) XP 2600+

model name : Intel(R) Core(TM)2 Duo CPU E6750 @ 2.66GHz
MemTotal: 4123780 kB

For reference, someone with a similar setup to mine:

model name : Intel(R) Core(TM)2 Duo CPU E6750 @ 2.66GHz
MemTotal: 1025344 kB

(Not at all a ram-dependent test, but whatever)

So, here's my question:

Why is my system performing so poorly? I'm running a stock i686 SMP kernel same as before, no special K7 kernels or anything.

I'd be willing to bet that this is your problem. I checked the dependencies of bc on my Gentoo server (`emerge -epvt bc`) and GNU MPFR was listed -- I do not know anything about how MPFR works, but multiple precision arithmetic is one of the things that will usually see a significant improvement when you move to 64-bit code. (It might be the required support for SSE and not simply wider registers, but since MPFR is based on GMP, it could very well be either.)

EDIT: I just noticed that bc links against GMP too.

Right. But that means reinstalling because a 64 bit kernel won't help if all my libraries and binaries are 32 bit.

Exactly. If your benchmark is actually representative of what you're doing on your server (e.g. video transcoding, encryption, compression, etc.) then reinstall. Otherwise, don't worry about it. There are other benchmarks that you can run that won't be as affected by 32- or 64-bit compilation; you picked one that is.

Make sure one of your lines has an entry that begins with "*" (like the 3rd line here does) this means your ntpd is locked onto a good source.

I don't have a /var/lib/ntp/ntp.drift file, but there was a /etc/adjtime and /etc/default/adjtimex.
I tried removing those, and doing those other steps. ntpq -p didn't give me any result with a + or * or anything prefixed to it. I appreciate the help, but I think I'm just going to just format and reinstall at this point, maybe try another distro. The amount of time I've spent struggling with this is ridiculous.

ps -ef |grep ntp |grep -v grep

Neat trick to save some time in situations like this:

# ps -ef | grep [n]tp

grep will match on any single character inside the brackets. For instance, if you had used [abcd]tp or [a-d]tp, grep would match on atp, btp, ctp or dtp. With the above, grep will only match on ntp. The real magic comes in when you take a look at your grep process in ps. Because ps is displaying the literal command rather than how the command interprets special characters, your grep will show up in ps with the square brackets included and thus won't be matched by your grep. Observe:

code:

[root@server ~]# ps aux | grep lfd
root     22333  0.0  1.2 131304 26396 ?        Ss   00:00   0:15 lfd - sleeping

You could also use pgrep I suppose. pgrep -l will list the PID and name of the matched processes.

I, too, love that trick. I sometimes wonder how many keystrokes I've lost correcting mistyped brackets, though. Probably not enough to have always used grep -v grep.

I'm a recent convert to the latest Ubuntu (11.04) and I use two hard disks pretty regularly. However, sometimes the one that Ubuntu isn't installed on sometimes isn't mounted on boot and I go into disk manager -> mount.

Is there a way to have it always mount on startup and get rid of the desktop shortcut thing that's there when it's mounted?

Edit, also is there a way to pipe text to the clipboard? E.g. "$ ./command | clipboard"

Yes, create an fstab entry for the partion (disk) you want to mount.

It's best to do this with the UUID

As 'root', edit the 'fstab' file in the /etc directory. The entry for your main drive should look like this:

pre:

/dev/sda[+]    /           ext[x]       defaults               1    1

Under that line, add this one for the second drive:

pre:

/dev/sdb[+]    /$dir[*]    ext[x]       defaults               1    2

[+]relevant partition number
[x]relevant filesystem type
[*]chosen mount directory

Note the different number at the end of the second line; only the root partition has 1; subsequent native filesystems have 2. Non-native filesystems get 0.

I assume you have SATA drives. If they're IDE, you use /dev/hda and /dev/hdb.

I have made it a habit to mount by UUID because that survives any device node renumbering if you happen to plug in an extra disk or something.

To connect, type "\\servername\share" into the address bar in Windows Explorer. I'm guessing only automatic network discovery is not functioning.

Speaking of IDE drives, do you know if there are any reliable models still around? I'm a bit put off by SATA annoyances on 2 drives I have, and since I only use this machine as the head of a small LAN of dedicated boxes, the better performance isn't important to me.

Not really, unless you go on the refurb market.

What annoyances though?

I'm currently trying to install GTK+ in ubuntu to dick around with, and trying to make the source keeps giving me an error saying that xinput.h cannot be found. Note that I've been using linux for a total of about a week, so please excuse my incompetence. Here's the error:

code:

Is there some obvious error here?

You're missing a dependency to build that:

code:

sudo apt-get instal libx11-dev

should solve that issue for you, but you'll run into another dependency problem right afterwards I'm sure.

Why are you trying to build gtk from source? Let the package manager do your installations for you whenever possible:

code:

sudo apt-get install libgtk-3-0

I'm going through the official tutorial and it said to install GTK from source. Also I didn't know the apt package name. Anyways, now that I've installed the package, I'm trying to compile the first example program in the tutorial, and pkg-config says it can't find the gtk pacakge in its search path:

code:

~/Code/C$ gcc base.c -o base `pkg-config --cflags --libs gtk+-2.0`
Package gtk+-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-2.0' found
base.c:1:21: fatal error: gtk/gtk.h: No such file or directory
compilation terminated.

Inspection of /usr/lib/pkgconfig reveals that there aren't any gtk related packages there.
What is my obvious mistake this time?

What are you trying to accomplish here?

While I applaud you trying to build your own packages, gtk is not exactly something you'd want a half-installed half-working version of.

As for solving your problem:
Does the gkt+ package come with a configure script? (packages usually do)
If so, run ./configure before you run make, and it will tell you what packages are missing, then use apt-cache search <name> (do an apt-get update first) to find what ubuntu package contains the needed dependencies (usually something like libsometing-dev) and then install that with apt-get install or aptitude install.
