[SOLVED] Question about configuring i3

I would like to use the "Tab" key instead of the "Shift" key in a default i3 configuration with the "Alt" key as modifier. I replaced "Shift" for "Tab" in ~/.i3/config, but it doesn't work as I expected. For example, by default $mod+Shift+1 moves the focused container to workspace 1. This doesn't work when changed to $mod+Tab+1, but works if set to $mod+Tab. The userguide (http://i3wm.org/docs/userguide.html#keybindings) states the available modifiers: Mod1 to 5, Shift and Control. It seems that Mod1 is "Alt", Mod4 is "Windows", but I don't know the others. Perhaps the reason is that the "Tab" key is not set as a modifier? Would you please assist me with this and thank you in advance.

That's right. Modifier keys modify input, while the Tab key sends input; If you hold down the Tab key, it will repeatedly send tabs to stdin. You can use xmodmap or setxkbmap to change around the mappings of keys. A common one which I use is setting Ctrl to the CapsLk key since, come on, how often does anyone use CapsLk?

Some questions about configuration in MAX.

Hello,everyone!
I have some questions about configuration in MAX(I am a jackaroo for motion control development),I hope I can get your help.
I use PCI-7344+UMI-7764+Servo amplifier+Servo motor,my MAX version is 4.2 and I use NI-Motion7.5
My question as following:
1,In Axis Configuration,for motor type,why I must select stepper but not servo?my motor is servo motor!If I select Servo,my motor can't run,I don't know why.
If I select stepper,though motor can work but I can't test encoder in MAX.
2,In Stepper settings,for stepper loop mode,why I must select open-loop but not close-loop?If I select close-loop,the servo motor doesn't work too.
3,If I want my two servo motors run at different velocity,How shoud I do?It seems I just can set the same velocity in MAX for my two servo motors.
My English is poor,Pls pardon me!I come from China.
Thank you for your help!

Hi,Jochen,
Thank you for your kindly help!
The manufacturer of the drive and motor that I am using now is Japan SANYO DENKI,drive type is RS1A01AA,motor type is R2AA06020FXP00.
And I use position control mode,thehe encoder's counts per revolution is 131072.I set the electronic gear ratio to 1:1 for drive.
Now,I can use Close-Loop to control the motor but still has some problems.When I configure it to run in closed loop mode, the motors behave strangely and never move to the target position.When I configure it to run in closed loop mode, the motors behave strangely and never move to the target position.The detail situation is as following
1,Motor can't run.
2, Or motor moves to a position, then moves in the same direction agian and eventually stops.
Except for the two points mentioned above,"Following Error" is occured frequently,I don't know why.
I am still not clear why I must set the motor type be stepper in MAX .
And I have another question:what the relationship between the steps and the counts?They have the proportion relations?I notice that there are a section said like this in help document: For proper closed-loop and p-command operation, steps per revolution/counts per revolution must be in the range of 1/32,767 < steps/counts < 32,767. An incorrect counts to steps ratio can result in failure to reach the target position and erroneous closed-loop stepper operation.
I am verry sorry I have too many questions!
I am very appreciate for your kingly help!Thanks again!

[SOLVED] Question about resolv.conf

I successfully configured my Arch box with a static IP by following the instructions on the Arch wiki page here but had a couple of questions about configuring /etc/resolv.conf:
1) What is the proper way to obtain the domain name that should be inserted into resolv.conf?
2) What exactly is this domain name used for? I read the man page but still don't really understand it. Why do I need a domain name if I already have a working set of nameservers to resolve IP addresses?
EDIT: @ewaller Yes I edited the OP because I realized that my original problem was that I just hadn't added a domain name in my resolv.conf file. I edited my original post because 1) the instructions are already posted clearly on Arch Wiki so my post really wouldn't be beneficial and 2) so I could ask my real question without making other people waste their time reading through my other nonsense

Yes, I know how to get a nameserver, but I'm asking about the domain name that goes in resolv.conf. The Arch wiki tutorial for setting up static IP uses the following resolv.conf as an example:
nameserver 61.23.173.5
nameserver 61.95.849.8
search example.com
My question has to do with what the "search example.com" does. I don't have a domain name associated with my machine, but if I remove that line, then I get "web page unavailable" when I try to load any web site, which suggests that I'm not connecting to any nameservers right?

[SOLVED] Question about CPU temperature

Hi everybody,
I just want to ask a question about "standard" CPU temperatures because my laptop (a Dell Vostro 3700) is permanently hot with the fans on even when I am not doing anything special.
I have CPU freq scaling active with the conservative governor, and I use Gnome Shell 3.2 with an nVidia using the nouveau driver.
Here are "stable" temperatures while writing this post:
# sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +72.5°C (crit = +103.0°C)
nouveau-pci-0100
Adapter: PCI adapter
temp1: +78.0°C (high = +100.0°C, crit = +110.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +73.0°C (high = +95.0°C, crit = +105.0°C)
Core 2: +73.0°C (high = +95.0°C, crit = +105.0°C)
And this is the output of mpstat
# mpstat -P ALL

10:16:50 PM 3 1.36 0.20 0.39 0.02 0.00 0.01 0.00 0.00 98.01
The fan, of course, is full speed (very annoying)
I think that these temperatures are quite high, but I don't know what's really causing all this heating because my laptop is basically idle.
Any suggestion?
Thanks.

[SOLVED] Question about GCC error messages.

I'm currently taking a course in C programming, and I have a question about the error messages returned by GCC.
When ever i try to compile a program containing syntax errors, i get cryptic and not very helpfull error messages.
If i try to compile:
#include <stdio.h>
int main(void)
int i;
i = 0
return 0;
I get following from GCC:
error.c: In function â:
error.c:8:2: error: expected â before â
But shouldn't the message be something like:
error.c: In function 'main':
error.c:8:2: error: expected ; before 'return'
or am I mistaken?

Woah. That is very strange. I've never seen that before.
I assume you're using Arch Linux. What text editor did you use to write the code? Which terminal application are you using?
...those questions are probably unrelated to the problem, but we might as well get them out of the way.

[Solved] Questions about Arch on T420s

Hello everybody,
I'm relatively new to Arch and switched from Ubuntu last year. Since then I've learned a lot about Linux in general due to the great documentation provided by the Arch community.
I've managed to install Arch on my Thinkpad T420s with an UEFI Setup using Archboot. But still there are open questions.
My first question is about the UEFI System partition and grub2. Should the UEFI partition be mounted to the filesystem? What about updating Grub2 (eg for setting boot parameters) when the UEFI System partition is not mounted to the filesystem. Up to now I've set boot parameters by manually mounting the UEFI partition and editing the Grub2's menu.lst equivalent. I think this is not optimal.
My second question is about some graphical artifacts in Gnome 3. The T420s uses Intel HD 3000 Graphics. Sometimes icons in nautilus disapear or get replaced by black planes when hovering over them with the mouse cursor. Similar black planes replacing icons can be observed sometimes in Evolution or Rhythmbox. Furthermore gnome-terminal becomes transparent sometimes when I'm scrolling or switching between powertop2 tabs. Anyone else observed similar issues on their T420s or on other models with an Intel HD 3000? I use several options for the i915 driver but none of them seem to be related to the graphical artifacts. Furthermore I've disabled dVT in the BIOS.
options i915 modeset=1
options i915 i915_enable_rc6=1
options i915 i915_enable_fbc=1
options i915 lvds_downclock=1
options i915 semaphores=1
My last question is about the USB ports on my T420s. I've 3 USB ports, one on the left side (USB2.0) and two (USB3.0 and another USB2.0) on the back side. When I plug in a HD on the left side everything works fine and the filesystem is automatically mounted. When I plug in the same HD on the ports of the back side the HD isn't even recognized. Interestingly when i boot with the HD plugged into the back side ports everything works fine. Can you point me any directions how to solve this problem?
Hopefully sombody using Arch on a T420s has already solved these issues and could share the solutions. Otherwise I would be grateful for any suggestions.
Sincerely yours,
Tobsen
Last edited by tobsen (2012-02-09 17:15:27)

Hi Tobsen, I have a T420 also. Perhaps my experiences will be some help?
Regarding the USB ports: I installed Arch on my T420 with the Kernal 3.0.3 snapshot and all the USB ports worked out of the box. That sounds like a problem with udev to me, though. Have you checked the wiki article on this?
Regarding the graphical artifacts: For me, when a popup window appears from hovering the mouse over an icon, the window is sometimes blank grey. It's totally inconsistent, and I can fix it by just hovering over it again, so I haven't really bothered to examine the source of the problem. Could this be related to your problem with the GPU? I figured it was a problem with the windows manager I'm using (Enlightenment e17), which is unstable.
Regarding UEFI: I don't use GRUB2, so this may not be good advice, but I personally feel like you should avoid auto-mounting partitions you don't always need. It slows down boot, and if the partition is mounted, user error could damage it. I say you should keep doing what you're doing.

[SOLVED] Question about systemd-user-session

Hi!
I'm trying to setup a systemd --user session (using user-session-units and xorg-launch-helper from aur).
I have a couple of questions; this is my .xinitrc now:
#!/bin/bash
export BROWSER=chromium
if [ -d /etc/X11/xinit/xinitrc.d ]; then
for f in /etc/X11/xinit/xinitrc.d/*; do
[ -x "$f" ] && . "$f"
done
unset f
fi
spacefm --desktop &
compton -cGCf -m 0.9 -i 0.8 -D 5 --shadow-exclude 'g:e:Conky' &
volumeicon &
/home/federico/Script/touchpadoff_onboot.sh &
#connman-ui-gtk &
/home/federico/Script/calised-script &
dimdaemon &
tint2 -c .config/tint2/dragonauta.tint2rc &
conky -p 5 -c Script/conky.conf &
exec openbox
1) is "if" statement required when using systemd-user-session? And if yes, how can I reproduce it?
2) "conky -p 5 " will wait 5 seconds doing nothing. Will this mean that other .service will wait for it to finish? (i guess no, since they're executed in parallel).
3) how can I export "chromium" as my default browser?
Thank you very much!

I followed everything in that wiki, and in KaiSforza and sofar github page.
I finally managed to get my old method (autologin to vt and autostart x) to work together with systemd --user: i put in .xinitrc "systemd --user" and deleted everything else.
So, my .config/systemd/user/ works. The problem is in the [email protected], i guess. I configured it like wiki says, mind to post here your /etc/systemd/system/[email protected]?

Question about configurations in Old Server

Dear All,,
I have a Question !
How will you find what are the configuration are in a server.. for example..
Is the DB configured RAC or DATA guard ?
Is RMAN configured or not ?
because at any time we have to face this request for Client who they don't have details regarding their Server,, (in Old Support Projects).
if i have a plan for a upgradation of database what are the documents i have to prepare and what are the steps i have to take at initial stage !
Regards
HAMEED

Hameed,
This should be documented and those documents should be provided by the clients.
You could do some investigation but again this will not be correct or complete without the documentation. For example, for RAC you could query the dynamic views (gv$instance, v$instance on each node) but this assume you already know what servers are configured. Or, you could refer to the RAC/DataGuard/RMAN configuration MOS docs for Oracle E-Business Suite and go through the steps to verify if those configurations are presented or not.
Thanks,
Hussein

Question about configuring REST web service in EBS instance

I am from EBS SCM team. From one wiki page, it says OA Framework provides REST framework to expose OAF BC4J objects as web services. Can you provide more details about how to configure REST web service for one EBS instance? Any related information is also helpful.
Edited by: 936859 on Sep 7, 2012 5:45 PM

IIRC you must activate PAPI-WS for the engine. In Studio you do it by right-clicking on the project, then "engine preferences". In enterprise/standalone you must activate PAPI-WS in the Admin Center.

The question about configuration Organization Unit on spro

Dear all.
I want to configuration Organization Unit on spro so I have created O.Units, Jobs and positions on Personnel Administration->Organizational Assignment->Organizational Plan but I can't see these values about O.Unit, job and position on SAP Access Easy .
How to see these values on SAP Access Easy ?
Can I input these values about O.Units, Jobs and positions on spro ?
Thanks so much.
Huyen Nguyen

instead of that
Define the Number ranges
in OOCR
for all the objects
Make a Template for Objects and Object Id
and upload the same thru PP01
than all the enties will sit in the SPRO
>note it is not mandatory to create thru SRPO wht in case if u have 4000 to 5000 Employees
So the best way is upload the Data thru LSMW thru Proper objects and Relatioships

[SOLVED] Question about Feh

I installed feh to use as a file browser image launcher (https://wiki.archlinux.org/index.php/Fe … e_Launcher) and as a desktop wallpaper manager (https://wiki.archlinux.org/index.php/Fe … er_manager), but it seems that I each time must use "sudo" for this. Therefore I think the script from the wiki page will not launch in Thunar and that the wallpaper will not load on start up in i3. In order to do this, I think I must add my user to a group, but I'm not sure which one or if it is the right way to solve it. Would you please assist me with this and thank you in advance.
Last edited by rayanamukami (2014-04-26 09:32:36)

Thank you for your advice, I should not use sudo as often as I do.
In Thunar opening an image with the feh_browser.sh script gives the following message.
Failed to execute application "feh_browser.sh".

For the wallpaper, I followed the wiki page about i3 (https://wiki.archlinux.org/index.php/I3 … _wallpaper). The following command gives the following message.

[SOLVED] Question about network setup static and dynamic

I am trying to set up an Arch install on my other pc. I have used Ubuntu and then Linux Mint for a year+ and Arch has always intrigued me so I am attempting to install it now. I do consider myself a pretty advanced computer user/programmer but computer networking has always confused me a little. I'm not quite understanding whether I setup my network with a static or dynamic ip. This is what I know
I have a static ip assigned to me by my ISP but I do have a router so it assigns me a different internal ip. Does that make my ip dynamic?
Last edited by c26zwj (2013-03-14 18:24:35)

If your ISP assigns a static IP then your IP in the internet is static. If you have a different internal IP then your router is running a DHCP server and performing network address translation. Your IP on the LAN is dynamic (unless you configure your router to assign static IPs, which can be useful if you want to forward ports to a specific computer). You most likely want to use DHCP to obtain a dynamic internal IP when you connect. The external IP is beyond your control (it is managed by the ISP and assigned to the router) so you do not need to worry about it.

[SOLVED] Question about conky-lua-arch.

I've managed to get conky-lua-arch up and working except for one minor issue. When I launch it, it automatically displays on the far right side of my 2nd monitor. This leads me to believe its alignment is pre-configured to run on the right side of the screen, which is fine, but how do I get it to be on the right side of my "primary" monitor instead? I've looked thru /usr/share/conky-lua-arch/clock-rings.lua but could not find an alignment or position parameter. I also could not find any other conky-lua-arch config files to look at. Any tips or suggestions are appreciated, thanks.
EDIT: The config file was located elsewhere. Solved.
