- The wireless here is "wlo1"
sudo ip link set wlo1 up
sudo wpa_supplicant -i wlo1 -c /etc/wpa_supplicant.conf &
sudo dhcpcd wlo1
- GUI config tool (optinal): sudo pacman -S wpa_supplicant_gui
- network={
ssid="Nha06-16-30 co j nhieu I"
- Fix issue can't start wpa_supplicant:
+ add no password require for user squallltt when he runs wpa_supplicant
to /etc/sudoers

create file conflict!!!!
* Disable beep sound:
- sudo rmmod pcspkr
- black list to prevent loading at boot:
sudo echo "blacklist pcspkr" > /etc/modprobe.d/nobeep.conf
* Check error X:
cat /var/log/Xorg.0.log | grep EE
/etc/X11/xorg.conf : if cannot start X, delete this file! - this evil file
* Fix VLC no start:
pacman -S vlc
/usr/lib/vlc/vlc-cache-gen -f usr/lib/vlc/plugins
pacman -S vlc # just to be sure ;)
* Terminal hack (display beautiful Arch Linux logo on terminal):
- Download the package
- makepkg
- Install alsi
- In terminal, run: alsi
- config files are in: ~/.config/alsi/
* fix truecrypt Dropbox volume mount as read only
- See log file: jounrnalctl -xn
- The error is:
Unable to monitor entire Dropbox folder hierarchy. Please run "echo 100000 | sudo tee /proc/sys/fs/inotify/max_user_watches" and restart Dropbox to correct the problem.
- Fix:
+ src:
+ sudo vi /etc/sysctl.conf
+ add this line at the end:
fs.inotify.max_user_watches = 100000
+ save the file and reboot. That's it.
* fix XFCE unable to start properly:
- rm -R .gconf .gnome2 .config/xfce4 .config/xfce4-session .cache
- I did pacman -Syu before and after the installation of xfce, but my problem was after the installation there was a file at /etc/profile.d/ that was causing a conflict and not allowing the system to update at all. I never noticed it and when it went back to the cursor so fast I automatically assumed everything was up to date and it had nothing to do. I removed the file, ran pacman -Syu, and everything updated as it should and xfce works flawlessly now.
- Summary: Please manually delete /etc/profile.d/ before updating. If . /etc/rc.conf fails in your login shell, please read the full announcement.
* mount USB flash drive, thumbdrive
pmount /dev/sdc1
* Installing teamviewer:
- Enable multilib: edit file /etc/pacman.conf
Include = /etc/pacman.d/mirrorlist
- The Teamviewer daemon must be running for Teamviewer 8 to work.
Execute 'sudo systemctl start teamviewerd' in a terminal.
* Openbox:
- config auto start file: vim .config/openbox/autostart
- obconf : theme configuration
- Menumaker: sudo pacman -S menumaker
+ mmaker -vf OpenBox3 (this will rescan all the installed application
and overwrite the existing menu.xml file)
- tint2 : taskbar
+ tint2conf : GUI configure tint
+ config file: ~/.config/tint2/tint2rc
- openbox --restart
- xcompmgr
+ xcompmgr -c &
- Wallpaper:
+ feh --bg-center ~/wallpapers/ArchLinux01.jpg
- Suspend: pm-suspend
+ Install: sudo pacman -S pm-utils
+ Locking the screen saver on hibernate or suspend
create file: /etc/pm/sleep.d/00screensaver-lock
# lock workstation on hibernate or suspend
username=squallltt # add username here; i.e.: username=foobar
export XAUTHORITY="$userhome/.Xauthority"
export DISPLAY=":0"
case "$1" in
su $username -c "/usr/bin/slock" & # or any other such as /usr/bin/xscreensaver-command -lock
*) exit $NA
chmod to 755, and make sure it owns by root:root
+ Arch IRC members say don't use pm-*crap, use this instead:
systemctl suspend
. How to lock screen when suspend using the above command
. Create file slock.service and put it in /etc/systemd/system/
Description=Lock X session using slock - Tung
. Then run: sudo systemctl enable slock.service
. Then everytime we suspend by using: systemctl suspend, it will lock
the screen as well
. List systemctl service: systemctl -t service -a | grep slock
- Adjust keyboard delay:
+ Put this to ~/.config/openbox/autostart
xset r rate 200 30
- Theme:
+ sudo pacman -S lxappearance (this allows us to change gtk application theme)
+ For Qt:
# Install
# add: export GTK2_RC_FILES="$HOME/.gtkrc-2.0" to .xinitrc file
before start openbox
# choose GTK+ theme for Qt by: /usr/bin/qtconfig-qt4
+ For transparentcy:
# devilspie syntax documentation:
# install: sudo pacman -S transset-df
# transset-df <value> (where value between 0..1)
# sudo pacman -S devilspie
# then start: xcompmgr &
# then start: devilspie -a &
# configure opacity: vim ~/.devilspie/opacity.ds
- Control volume from keyboard:
* Graphic driver:
- Install Bumblebee (for HP laptop - HP Pavilion dm3-1123tx)
+ sudo pacman -S intel-dri xf86-video-intel bumblebee nvidia
+ add user to bumblebee group: gpasswd -a squallltt bumblebee
+ start bumblebee automatically at startup: systemctl enable bumblebeed
+ reboot!
+ by doing those previous steps, it fix the error:
. "EnterVT failed for screen 0"
. that means: every time a computer is suspended or press Ctrl+Alt+F2
then the X server is terminated and all other applications are killed
+ The url link also provides a troubleshooting:
Fatal IO error 11 (Resource temporarily unavailable) on X server
Change KeepUnusedXServer in /etc/bumblebee/bumblebee.conf from false to true
- For VirtualBox guest running Arch:
+ if the file ~/.xinitrc has:
sudo VBoxClient-all &
sudo systemctl start vboxservice.service
then need to make sure that we don't need sudo password for
VBoxClient-all and systemctl (or else, we will receive error
EnterVT failed for screen 0). Solving by doing this:
. sudo visudo -f /etc/sudoers
. add:
## Allow sudo for user squallltt and let him run VboxClient-all without requiring a password
squallltt ALL = PASSWD: ALL, NOPASSWD: /usr/bin/VBoxClient-all, /usr/sbin/ip, /usr/sbin/wpa_supplicant, /usr/sbin/dhcpcd, /usr/bin/truecrypt, /usr/bin/systemctl
* Disable menu in Virtualbox:
- VBoxManage setextradata global GUI/Customizations noMenuBar,noStatusBar
* Vim: write to root permission file in vim
- add to .vimrc file: cmap w!! w !sudo tee %
- run: vim /path/to/file as usual
- then when we want to save, just issue: w!!
- then press l
* irssi : IRC
vim ~/.irssi/config
There are loads of irssi scripts which do this, but the truth is irssi actually supports these things very well out of the box. Here's how.
Start up irssi, then:
/nick MyIRCNick
/SERVER ADD -auto -network freenode 6667 <password>
(you may have to shutdown and restart irssi at this point for it to recognize the network name "freenode" in the next step)
/CHANNEL ADD -auto #ubuntu freenode
Another method of auto-identifying is seen below. The above is generally preferred.
/NETWORK ADD -autosendcmd "/^msg NickServ IDENTIFY password;wait 2000" freenode
Ignore join, part, quit message: add the following to config file:
ignores = (
channels = ( "#archlinux", "#vim", "#python" );
network = "FreeNode";
level = "MODES";
channels = ( "&amp;bitlbee" );
network = "BitlBee";
* Screen recording:
* Mount iso file
fuseiso -p testimage.iso testimagemountpoint
to unmount:
fusermount -u <mountpoint>
* Fix Gtk-WARNING **: Unable to locate theme engine in module_path: "murrine"
sudo pacman -S gtk-engines
sudo pacman -S gtk-engine-murrine
