I've tried both commands, but they print the following and I still have the same problem:

[Mostly Solved] Netctl can't use interface, interface is up

Hey all,
I've previously used NetworkManager, but after some issues I tried to use something a bit less bloated to troubleshoot and found netctl to be amazing, how networking should always be. And magically my wireless at uni started working again. Initially netctl worked fine, it still does for the most part but on boot the interfaces seem to be hogged by something else, an issue NetworkManager was able to resolve apparently.
To use netctl, I have to start NetworkManager, then stop it. I can then use netctl without issue.
In a troubleshooting attempt I tried disabling udev renaming, so I am back to eth0 and wlan0: Issues persist.

Sorry, you are right I haven't worded this well.
You are correct, there are no other network management daemons running, and on boot the interface is DOWN.
Despite being down, netctl can not start the interface.
If I manually 'ip link set wlan0 down', despite it already being reported as DOWN, netctl can then use the interface.
Here is some output, after logging in:
[root@t60 ~]# netctl start tomato
Job for [email protected] failed. See 'systemctl status [email protected]' and 'journalctl -xn' for details.
[root@t60 ~]# netctl status tomato

As you can see, netctl thinks the interface is UP, but ip says it is DOWN. To get going from this point, this works:
[root@t60 ~]# ip link set wlan0 down
[root@t60 ~]# netctl start tomato
[root@t60 ~]#

Heroes of the Storm with bumblebee doesn't use NVidia Card.

Hi,
So I have bumblebee installed it works perfectly.
Problem:
executing "optirun wine HeroesSwitcher.exe" it doesn't use the Nvidia GPu.
It's probably caused by the launcher is starting the game in a separate process and exiting right after, witch in turn termintes it's parent process "optirun".
Is there any way that I can like run all the wine programs with bumblebee. or a way to execute the game with the Nvidia GPU.
Sorry for the English.
Regards,

Is there any insight here? I can't seem to get my brand new work y70 to use the NVidia graphics card for any external displays! What the heck is going on!? And, moreso, why can't even the crummy Intel onboard graphics push 2560 x 1600 via either HDMI or USB (through a replicator)? I've had a 30" monitor running 2560 x 1600 for 5 years. This is a brand new laptop and can't push out high res?! It's crazy to me!! EDIT: I presently have the Intel display adapter disabled in the device manager. I have video on the laptop display but I can no longer get ANY external displays to work. Which means, to me, it would seem that the NVidia GPU is 100% relegated to the laptop display, ONLY.

[SOLVED] Bumblebee/bbswitch Not Disabling Nvidia Card

Hello all. I've been able to resolve a wide variety of problems by searching through the posts here, but it seems I've come up empty on this one.
I'm running Arch on a Sager NP5160 (Clevo W150HN), i7-2630 QM, 8 GB RAM, running Optimus with an Nvidia GT 540M Optimus setup.
I've had Bumblebee and bbswitch running fine in the past, but recently I needed to reinstall Arch (my own fault).
I installed bumblebee and bbswitch again, as described on the wiki.
However, once everything is installed and configured, bbswitch is still unable to deactivate my Nvidia card.
I'm using the proprietary Nvidia driver.
I have verified that bumblebee.conf has the driver set to Nvidia (not nouveau), and uses bbswitch.
I have also tried blacklisting both nouveau and nvidia, as well as adding bbswitch to the modules section of my mkinitcpio.conf file (and regenerating the initramfs).
A curious point that I have noted is that the Nvidia card is disabled during boot, and up until I login.
Once my information loads, the Nvidia card is activated and I cannot deactivate it, even manually.
Here is the dmesg output when I run glxspheres64 using bumblebee:

Sorry to bump this, but I've found some more information.
Unfortunately, I'm not sure what to do with it yet.
I've uninstalled and reinstalled the relevant packages outlined in the Bumblebee wiki.
When my laptop boots, the Nvidia card is disabled up until I log in, at which point it appears to be perpetually enabled, unless the Optimus indicator lights are showing incorrectly.
This is the log output I receive when I run optimus glxspheres64:

I got a solution:`rmmod acer_wmi` and adding it to blacklist solves the problem
https://bugzilla.redhat.com/show_bug.cgi?id=674353

SOLVED: How can I use or call a function that returns %ROWTYPE?

Hi
edit: you can probably skip all this guff and go straight to the bottom...In the end this is probably just a question of how to use a function that returns a %rowtype. Thanks.
Currently reading Feuerstein's tome, 5th ed. I've downloaded and run the file genaa.sp, which is a code generator. Specifically, you feed it a table name and it generates code (package header and package body) that will create a cache of the specified table's contents.
So, I ran:
HR@XE> @"C:\Documents and Settings\Jason\My Documents\Work\SQL\OPP5.WEB.CODE\OPP5.WEB.CODE\genaa.sp"
749 /
Procedure created.
HR@XE> exec genaa('EMPLOYEES');which generated a nice bunch of code, viz:
create or replace package EMPLOYEES_cache is
    function onerow ( EMPLOYEE_ID_in IN HR.EMPLOYEES.EMPLOYEE_ID%TYPE) return HR.EMPLOYEES%ROWTYPE;
    function onerow_by_EMP_EMAIL_UK (EMAIL_in IN HR.EMPLOYEES.EMAIL%TYPE) return HR.EMPLOYEES%ROWTYPE;
    procedure test;
end EMPLOYEES_cache;
create or replace package body EMPLOYEES_cache is
    TYPE EMPLOYEES_aat IS TABLE OF HR.EMPLOYEES%ROWTYPE INDEX BY PLS_INTEGER;
    EMP_EMP_ID_PK_aa EMPLOYEES_aat;
    TYPE EMP_EMAIL_UK_aat IS TABLE OF HR.EMPLOYEES.EMPLOYEE_ID%TYPE INDEX BY HR.EMPLOYEES.EMAIL%TYPE;
    EMP_EMAIL_UK_aa EMP_EMAIL_UK_aat;
    function onerow ( EMPLOYEE_ID_in IN HR.EMPLOYEES.EMPLOYEE_ID%TYPE)
        return HR.EMPLOYEES%ROWTYPE is
        begin
            return EMP_EMP_ID_PK_aa (EMPLOYEE_ID_in);
        end;
    function onerow_by_EMP_EMAIL_UK (EMAIL_in IN HR.EMPLOYEES.EMAIL%TYPE)
        return HR.EMPLOYEES%ROWTYPE is
        begin
            return EMP_EMP_ID_PK_aa (EMP_EMAIL_UK_aa (EMAIL_in));
        end;
    procedure load_arrays is
        begin
            FOR rec IN (SELECT * FROM HR.EMPLOYEES)
            LOOP
                EMP_EMP_ID_PK_aa(rec.EMPLOYEE_ID) := rec;
                EMP_EMAIL_UK_aa(rec.EMAIL) := rec.EMPLOYEE_ID;
            end loop;
        END load_arrays;
    procedure test is
        pky_rec HR.EMPLOYEES%ROWTYPE;
        EMP_EMAIL_UK_aa_rec HR.EMPLOYEES%ROWTYPE;
        begin
            for rec in (select * from HR.EMPLOYEES) loop
                pky_rec := onerow (rec.EMPLOYEE_ID);
                EMP_EMAIL_UK_aa_rec := onerow_by_EMP_EMAIL_UK (rec.EMAIL);
                if rec.EMPLOYEE_ID = EMP_EMAIL_UK_aa_rec.EMPLOYEE_ID then
                    dbms_output.put_line ('EMP_EMAIL_UK lookup OK');
                else
                    dbms_output.put_line ('EMP_EMAIL_UK lookup NOT OK');
                end if;
            end loop;
        end test;
    BEGIN
        load_arrays;
    end EMPLOYEES_cache;
/which I have run successfully:
HR@XE> @"C:\Documents and Settings\Jason\My Documents\Work\SQL\EMPLOYEES_CACHE.sql"
Package created.
Package body created.I am now trying to use the functionality within the package.
I have figured out that the section
    BEGIN
        load_arrays;
    end EMPLOYEES_cache;
/is the initialization section, and my understanding is that this is supposed to run when any of the package variables or functions are referenced. Is that correct?
With that in mind, I'm trying to call the onerow() function, but it's not working:
HR@XE> select onerow(100) from dual;
select onerow(100) from dual
ERROR at line 1:
ORA-00904: "ONEROW": invalid identifier
HR@XE> select employees_cache.onerow(100) from dual;

ERROR at line 1:
ORA-00936: missing expressionHe provides the code genaa.sp, and a very brief description of what it does, but doesn't tell us how to run the generated code!
Now, I have just done some googling, and it seems that what I am trying to do isn't possible. Apparently %ROWTYPE is PL/SQL, and not understood by SQL, so you can't call onerow() from sql. Correct?
So I try wrapping the call in an exec:
HR@XE> exec select employees_cache.onerow(100) from dual;
BEGIN select employees_cache.onerow(100) from dual; END;
ERROR at line 1:
ORA-06550: line 1, column 30:

Of course, now that I'm looking at it again, it seems that the way to go is indicated by the first error:
PLS-00428: an INTO clause is expected in this SELECT statement
So am I supposed to create a type of EMPLOYEES%ROWTYPE in a PL/SQL procedure, and the idea of this code, is that the first call to onerow() runs the initialiation code, which populates the cache, and all subsequent calls to onerow() (whether by my session or any other) will use the cache?
I've had a stab at this, but still, no joy:
create or replace procedure testcache is
    emp employees%rowtype;
    begin
        select employees_cache.onerow(100) from dual into emp;
        dbms_output.put_line('Emp id: ' || emp.employee_id);
    end testcache;

Ha, figured it out

Hopefully you also figured out that the example is just that: a technical example of how to use certain Oracle functionality. Unfortunately it is also an example of what you should NOT do in an actual application.
That code isn't scaleable, uses expensive PGA memory, has no limit on the amount of memory that might be used and, contrary to your belief will result in EVERY SESSION HAVING ITS OWN CACHE of exactly the same data if the session even touches that package.
Mr. Feuerstein is an expert in SQL and PL/SQL and his books cover virtually all of the functionality available. He also does an excellent job of providing examples to illustrate how that functionality can be combined and used. But the bulk of those examples are intended solely to illustrate the 'technical' aspects of the technology. They do not necessarily reflect best practices and they often do not address performance or other issues that need to be considered when actually using those techniques in a particular application. The examples show WHAT can be done but not necessarily WHEN or even IF a given technique should be used.
It is up to the reader to learn the advantages and disadvantages of each technicalogical piece and determine when and how to use them.

That is correct. To be used by SQL you would need to create SQL types using the CREATE TYPE syntax. Currently that syntax does not support anything similar to %ROWTYPE.

NO! That is a common misconception. Each session has its own set of package variables. Any session that touches that package will cause the entire EMPLOYEES table to be queried and stored in a new associative array specifically for that session.
That duplicates the cache for each session using the package. So while there might be some marginal benefit for a single session to cache data like that the benefit usually disappears if multiple sessions are involved.
The main use case that I am aware of where such caching has benefit is during ETL processing of staged data when the processing of each record is too complex to be done in SQL and the records need to be BULK loaded and the data manipulated in a loop. Then using an associative array as a lookup table to quickly get a small amount of data can be effective. And if the ETL procedure is being processed in parallel (meaning different sessions) then for a small lookup array the additional memory use is tolerable.
Mitigating against that is the fact that:
1. Such frequently used data that you might store in the array is likely to be cached by Oracle in the buffer cache anyway
2. Newer versions of Oracle now have more than one cache
3. The SQL query needed to get the data from the table will use a bind variable that eliminates repeated hard parsing.
4. The cursor and the buffer caches ARE SHARED by multiple sessions globally.
So the short story is that there would rarely be a use case where ARRAYs like that would be preferred over accessing the data from the table.

[solved] (how) can I use my laptop as a router for other computers?

First of all, I have to admit that I do not know too much about networking. Just enough to make the simple things work properly.
I have a laptop, which accesses the internet by wireless lan. The router is in my downstairs office. So far so, good, I have a media computer (both running Arch) in my room upstairs, intended to watch dvds or internet tv on the tv screen.
Connecting this computer to the downstairs-router by cable is not possible. Now I wondered, if I really needed to buy a wlan-card (any suggestions which one works well with linux?) or if there might be an (easy) solution using my laptop as (sort of) a router, connecting them by cable and establishing a lan connection between both of them.
Is it possible, to get internet access on the media computer that way, without to much effort? And what do I need to do to get it working?

Well, I tried to set it up to day, realizing that it is probably not as easy as it appears to be.
I did everything according to the wiki but from the laptop I can access either the internet OR the other computer, but not both at the same time. It seems to depend on which network profile I activate first.
If I first activate and configure the ethernet card, I can acces the other computer (I tried ping and ssh), but if I then start the wlan profile I cannot access the internet on the laptop. If I start the internet profile first and then configure the ethernet card, I cannot ping the media pc anymore.
I'm not sure what could be wrong, as I just did everything according to the wiki entry. Ideas?

[SOLVED] vim can't use colorscheme from ~/.vim/colors

Hello
I wanted to use the Molokai Theme for vim. So I downloaded molokai.vim from http://www.vim.org/scripts/script.php?script_id=2340 Copied it to ~/.vim/colors folder. In vim I enter :colorscheme molokai.vim but it can't find it.
Also install molokai-vim from AUR but still. E185: Cannot find color scheme 'molokai.vim'
Any thoughts?
Last edited by blackout23 (2013-04-01 08:15:38)

I'm sure I tried it with and without extension and it didn't work.
However after creating a .vimrc (didn't have one before) according to this:
http://dthettich.tumblr.com/post/131989 … rc-molokai
It worked.
@WonderWoofy
The AUR package installed it into that directory.
Thanks to all!

Can I use nvidia geforce gtx 650 2gb video card for after effects?

Hi I saw the list of graphics cards that are compatible with after effects... and am wondering if the nvidia geforce 650 2 gb would work?
I realized all the graphics cards have cuda cores, the gtx 650 2 gb isnt on the list but it has 384 cuda cores?
Is it compatible?
GTX 650 2g:http://www.newegg.com/Product/Product.aspx?Item=N82E16814133474

If it's not on the system requirements list, then After Effects won't use it for GPU acceleration of the ray-traced 3D renderer. Read this page for details about what this means:
http://blogs.adobe.com/aftereffects/2012/05/gpu-cuda-opengl-features-in-after-effects-cs6. html

[SOLVED] How can I use numix as my lightdm-gtk-greeter theme?

I've gone into /etc/lightdm/lightdm-gtk-greeter.conf and set the theme to numix, however it didn't change anything. So then I went into /etc/lightdm/lightdm.conf and specifically set the greeter-session to lightdm-gtk-greeter. It's the only greeter I have installed.
I did a reboot after each change but there was no effect.
Thanks.

[SOLVED] NetworkManager can't use DHCP

I just installed a fresh Arch Linux on whatever network modem is onboard the Gigabyte 990FXA-UD3 motherboard. The ethernet port works out-of-the-box using dhcpcd on the installer ISO and on my actual installation of Arch. Using KDE, I followed NetworkManager's setup guide in the wiki, but if I try to connect to anything, it instantly fails once I click on it. Then I tried clicking on Manage Connections and making a new Wired connection. It still failed. Then I tried changing that connection from DHCP to manual IPv4 and DNS numbers, and it worked just fine. I've done a lot of Googling, but nothing in the wiki or forums is fixing this issue for me.

I'm confused, did someone prevent you from updating the Wiki?
Yes, I tried, but I admittedly lack the skills to debate technically, with someone who obviously possesses the skills.

Honestly though, at this point, your question is no longer important.
What would be cool though is for someone with the expertise on this subject to take notice, figure out exactly what is lacking in the wiki and be willing to contribute the info for the good of the community, which I believe should include the Arch newbs or non coders / programmers.
Then be able to persuade Scimmia and Lahwaacz that in fact, something needs "fixed", even though from their perspective (Linux guru?) there is nothing wrong or missing.

Using nvidia-settings without X/over ssh

I have a computer with an nvidia GTX 670 that I want to control remotely. However, I have problems using nvidia-settings over ssh. When trying to use it, I get this error:
ERROR: Cannot open display ':0.0'.
When a user is logged in an xfce session locally, I can use nvidia-settings without issue, using the command line over ssh. As soon as I log out from the xfce session, I get
Invalid MIT-MAGIC-COOKIE-1 key

ERROR: Unable to query attribute GPUCoreTemp specified in query '[gpu:0]/GPUCoreTemp' (no Display connection).
How can I use nvidia-settings without the need for a user to be logged in locally?

I am trying to do the same thing with a GT 240. I found something promising here:

Since you do have a local monitor, it may be easier not having to fake one. I don't have a monitor, I haven't gotten around to trying the Xorg stuff yet.
