archlinux: annoying missing icons

I had a fresh install of Archlinux running GDM with Gnome and Xfce.
After installing a couple of apps (Firefox and Chrome) the icons were missing in the menu entries.

By running the below command as root and restart, the issue is fixed.

# gtk-update-icon-cache -t -f /usr/share/icons/hicolor

The dream is over

For the last 3 weeks I was involved in a series of phone interviews for a job position in a famous company in the Netherlands. My level of confidence was increasing after each interview. The last interview was the toughest one, that included video conference with the IT team and several technical questions with coding on the go, together with a business question.

archlinux / gdm - execute commands at initialization

In order to execute commands at the beginning of the X user session - before the window manager is started -  the xprofile file can be used. The xprofile file is similar in style to xinitrc.

Firstly, create the file ~/.xprofile if it does not exist already. Then, simply add the commands for the programs you wish to start with the session.


archlinux - touchpad driver

In my old Presario V3000 the touchpad was working after installation, however the behaviour was a bit strange: the sensitivit was too high and when touching the cursor change the position on screen, like the touchpad area is related to a fixed position on screen.

To resolve this, the synaptics driver was installed.

# pacman -S xf86-input-synaptics

Then perform the configuration:

"The primary method of configuration for the touchpad is through an Xorg server configuration file. After installation of xf86-input-synaptics, a default configuration file is located at /usr/share/X11/xorg.conf.d/70-synaptics.conf. Users can copy this file to /etc/X11/xorg.conf.d/ and edit it to configure the various driver options available."

Example of configuration file with some common options, including vertical, horizontal and circular scrolling as well as tap-to-click:


Section "InputClass"
    Identifier "touchpad"
    Driver "synaptics"
    MatchIsTouchpad "on"
        Option "TapButton1" "1"
        Option "TapButton2" "3"
        Option "TapButton3" "2"
        Option "VertEdgeScroll" "on"
        Option "VertTwoFingerScroll" "on"
        Option "HorizEdgeScroll" "on"
        Option "HorizTwoFingerScroll" "on"
        Option "CircularScrolling" "on"
        Option "CircScrollTrigger" "2"
        Option "EmulateTwoFingerMinZ" "40"
        Option "EmulateTwoFingerMinW" "8"
        Option "CoastingSpeed" "0"
        Option "FingerLow" "30"
        Option "FingerHigh" "50"
        Option "MaxTapTime" "125"

Alternatively, the Graphical tool "GPointing Device Settings" can be installed to provides graphical on the fly configuration for the pointing device

# pacman -S gpointing-device-settings
