[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] Questions about pacman -Qk and -Qkk output.
I was looking through the pacman manual today to see if there was anything I could add to a some Arch maintenance scripts I've been working on and came across -Qk which, among other things, lists missing files. I ran pacman -Qk in terminal and found a few package installations were missing files. I reinstalled them manually check again and the files were no longer missing. The first package I saw that was missing a file was gnome-command-center for instance.
So I really have two questions.
1) Is it normal for packages to have missing files?
2) Is it a good idea to reinstall these packages to replace the missing files.
I then ran pacman -Qkk, and got even more disturbing information such as modification time mismatches and size mismatches.

I'm assuming all of those are bad. "Warning" rarely sounds friendly, though for those files I've modified myself, such as passwd, shadow, and group, its okay. I assume I can fix msot of these by running # pacman -S {package}?
Last edited by nstgc (2014-09-14 01:26:04)Awk processes the output from pacman, splits it using [white]space[s] as delimiter and prints only first field $1, which is the package name. Those reoccur if several files are involved, so just to be sure, I also used awks sort, maybe that could be skipped or alternatively sort command outside awk used instead. This sorted output gets fed into uniq, which outputs only unique strings coming from input. And that leaves you with the package list.
Edit: I think those are whitespaces actually, which if I recall correctly include space.
Edit2: So this might be better and certainly a little faster:
pacman -S $(pacman -Qkq | awk '{print $1}' | uniq)
# And this should be even faster, since the output pacman
# delivers seems to be sorted anyway. Should you parse
# something else, use my first suggestion instead.
pacman -Qkq | awk 'BEGIN{ y=0; }; {x=$1; if (x == y){ next; }; print $1; y=x;}'
Edit3: Out of curiosity I tested different methods measuring execution time with a input file consisting out of 1443 lines from pacman -Qkkq. Here are the results and the bottom is the test script.

The awk internal sorting is the slowest method, but it seems it initializes longer, since there appears to be a constant difference between internal and external sorting. Uniq fed by awk is faster with smaller loops, but gets slower if repeated more often, yet overall remain fastest with the unique function I used within awk. It appears the more lines the input has, the slower uniq in comparison uniq in awk gets. Here is the testing script:
#!/bin/bash
LOOPS=('10' '20' '50' '100' '200' '500' '1000' '2000' '5000' '10000' '20000' '50000');

[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

[SOLVED]manually set resolv.conf nameserver when using netcfg
This is probably simple, but i can't seem to find the answer anywhere (wiki/google/forums), so if someone could point me in the right direction that would be great!
When netcfg brings up my wireless connection it automatically overwrites my nameserver settings in /etc/resolv.conf
how do i set it up so that it keeps my settings?

[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?

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 /etc/vconsole.conf and setfont command
Running setfont command, either
setfont Lat2-Terminus16
or

gets me "Couldn't get a file descriptor referring to the console"
When I installed the system I set my keymap to Lat2-Terminus16, doesn't this force the fonts to load in the bootup process?

*Solved* Question about ATI Drivers
Ok, I'm just finished installing, and I know most distro's, ask you to remove the open source drivers, before adding in FGLRX drivers. Looking at the wiki, I didn't noticed if this needed to be done, and after going through the install, I rebooted. It went as planned until kdm went to load. The screen was unreadable. I used the cd media to mount root, and removed catalyst, and re-installed the opensource drivers. All is well atm, so I'm trying to figure out what I missed. My question atm though is during the FGLRX install, it ask's if you want to removed the opensource drivers due to conflict. If I hit yes, will pacman it automatically remove the required drivers, or do I need to manually remove the Fx86 drivers on my own?
I do apologize for not having a /etc/X11/xorg.conf report, as it slipped my mind while fixing everything. I'll try to make a better habbit of getting it made. I did do a aticonig --inital before the reboot, so i know it won't that.
If I missed anything on the wiki, please let me know, I'll look again at it after dinner.
Thank you all for your time in the matter.

Hi there
First off, which installation method are you following? (ABS using the AUR package, the unofficial repository or the AMD installer). Depending on which method you use, you'll have (or not) a resolved dependency. For instance, you have to remove both the open source driver and your former xorg.conf file (safer is to back it up) to be able to install Catalyst with the AMD's site installer.
If you use AUR (with a tool like Yaourt for example) or the repo method, pacman/yaourt should do it for you, but in a lot of cases it doesn't (I switched to Catalyst having my OpenBox session built already, so when I tried to remove the open source driver it complained about all of the apps that I had installed for removing a dependency like libgl or mesa) and you'll have to do a pacman -Rdd xf86-video-ati to make it work
I'm wondering if you remembered to add the mkinitcpio hook (which is needed to make Catalyst work).
What I would suggest is to re-read the wiki page for Catalyst, see if your card is still supported by Catalyst, maybe your card needs Catalyst-Legacy...
Best of Luck with that
I figured it out, and got it working. I had a typo adding the module for flgxr driver. Fixed it and a soft boot later, all is well. I also deicided to make it so I have to "startx" into my gui, incase this happens again, I won't need the installation media. Thanks for the input. -
[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] Questions about netcfg
Hello,
I just set up a very basic Arch install and to keep in this spirit, I decided to go with netcfg. I got it all working but I do have some questions, especially about it I need certain packages.
1: At home we have a wifi network that is secured with WPA. I take it, according to the wiki, that I have to use wpa_actiond for this? Or is this just for roaming? (as this part of the wiki suggests "required for automatic/roaming wireless connections".)
2: I'm using wifi-select as well for when I'm on the go. I have added this information as suggested per the wiki to /etc/rc.conf, to automatically connect to my home network? Is this redundant when using wifi-select and/or will this interfere with wifi-select when I want to connect to another network?
I'm a little struggling with the English to get my point across in these questions but I think you'll understand. If not, I'll try to elaborate a little more. Thanks in advance for your help!

I say so, because as I said English is not my first language.
Raynman wrote:2: As the wiki says, net-auto-wireless is useful for roaming, moving between a number of known networks (for example, I have profiles for home, university and public wifi on the train). It also says that this is the part of netcfg that requires wpa_actiond. If you usually use your home network, you might opt for the simpler net-profiles and rely on wifi-select for when you occasionally need to connect to some other network; then you can drop wpa_actiond.
Thanks, I get it! I'll mess around with it tomorrow. -
[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!
Last edited by nierro (2013-04-06 17:56:17)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]?

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".
Failed to execute child process "/home/kohaku/feh_browser" (Permission denied).
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.
$ feh --bg-scale /path/to/image.file
feh WARNING: /home/kohaku/.feh/wallpaper/touhou.png - No read access
feh ERROR: Unable to load image /home/kohaku/.feh/
I have added
exec --no-startup-id sh ~/.fehbg
to

The default .bashrc file looks like this. When installing rvm I noticed that it is not sourcing scripts under /etc/profile.d.
# ~/.bashrc
# If not running interactively, don't do anything
[[ $- != *i* ]] && return
alias ls='ls --color=auto'
PS1='[\u@\h \W]\$ '
I just solved my issue by adding the following code to .bashrc. I was just wondering if this should be done by default perhaps in the package that installs /etc/skel/.bashrc?
if [ -f /etc/profile ]; then
. /etc/profile
fi
Last edited by MikeW (2014-11-12 05:28:25)Seems that it is an rvm issue. After a bit of searching for rvm problems I found this post that gave me the rvm specific solution. This is probably the preferred fix since its just rvm that's the issue here.
http://askubuntu.com/questions/40287/et … ng-sourced
The key is serveral posts down...
Installing RVM as multiuser requires the user to run this command:
echo '[[ -s "/etc/profile.d/rvm.sh" ]] && . "/etc/profile.d/rvm.sh" # Load RVM function' >> ~/.bashrc
So I can remove the /etc/profile bit now. Thanks for stearing me in the right direction to fix this. -
[SOLVED] Question about Saving Cached Packages
Hey Guys,
I've got a couple of systems running Arch right now, and have a 3rd that I was thinking about setting up this weekend. The second of the 2 I already have is very recent and I haven't cleared out the package cache yet. If I were planning on installing the same applications on the next system, could I just save the package files in /var/cache/pacman to a CD or something and just copy them back to the new system once I have the CORE installed? I figure this would save an hour or so of downloading, which would be nice. If it is possible, is there anything else I need to have aside from the packages themselves (ie. is there like a header file somewhere)?
Thanks!
Swill
Last edited by Mr. Swillis (2008-11-21 06:01:15)Well - it could work - or it might not. Better solution is to make another repository using your recent packages.
Try to write this to your /etc/pacman.conf:
[name_of_your_own_repo]
Include = /path_to_your_own_repo
I haven't tried it personally, but it should work. If it will prefer packages from other repos (community, extra), then write it somewhere above other repos in /etc/pacman.conf or use pacman -S name_of_your_own_repo/package
You should read about Pacman at Arch-wiki to know more about making your own repository before you will decide to try it.
Either way, write your experience here, please, I'd want to know if it works or not

Don't worry if some of the letters show up as white squares or as other symbols. It's probably just the console font missing those glyphs. The glyph codes are correct and if you press the correct keys they will show up fine when (or if) you set up a graphical environment later.
