Run Script on Resume From Suspend in Kubuntu

http://ubuntuforums.org/showthread.php?t=1484156

  1. Have a look at folder /etc/pm/sleep.d/ - all scripts within this folder are automatically run as root-user after/before suspend or hibernate.
  2. A script needs to look like this example:
#!/bin/bash
case "$1" in
    hibernate|suspend)
        ACTION BEFORE SUSPEND/HIBERNATE
        ;;
    thaw|resume)
        ACTION AFTER RESUME
        ;;
    *)
        ;;
esac
exit $?

Building QEMU in MSYS

Mostly follow http://en.wikibooks.org/wiki/QEMU/MinGW

For glib: 

export LIBFFI_CFLAGS="-I/opt/qemu/lib/libffi-3.0.13/include"
export LIBFFI_LIBS="-L/opt/qemu/lib -lffi"

For pkg-config: 

export GLIB_CFLAGS="-I/opt/qemu/include/glib-2.0 -I/opt/qemu/lib/glib-2.0/include"
export GLIB_LIBS="-L/opt/qemu/lib -lglib-2.0"
export PKG_CONFIG_PATH=/opt/qemu/lib/pkgconfig
export ACLOCAL_PATH=/opt/qemu/share/aclocal

For qemu:

I got errors about PKG_PROG_PKG_CONFIG when building pixman. I just commented out the 7 lines starting with PKG_PROG_PKG_CONFIG in the generated “pixman/configure” script since I wasn't using GTK anyway.

Burning Blu-Rays with K3B

Out of the box on a Kubuntu 14.04.1 install, k3b will give Input/Output errors at the end of writing a blu-ray, even though the data appears to write successfully. This is due to growisofs having bugs. Installing the cdrecord package manually from http://sourceforge.net/projects/cdrtools/files/alpha/ (defaults to /opt/schily) will allow k3b to use cdrecord instead of wodim. Then, configuring the k3b project to not be multi-session will force k3b to use mkisofs instead of growisofs and avoid the bug, allowing blu-ray burning to complete successfully. Reference https://bugs.kde.org/show_bug.cgi?id=281818.

Carrier Reset for HTC One M8 on Sprint

I was getting a “Unable to establish a wireless data connection” error on my HTC One M8 on Ting using Sprint's network. The technician suggested calling ##72786#' to do a “Carrier Reset”. It retried to activate several times unsuccessfully, but on the last attempt I stepped outside and then it succeeded. Since then my mobile data connection seems to work fine again.

KDE Plasma Task Manager button width

When turning on Group by Program name but turning off Combine into a single button, the maximum task manager button size decreases. I fixed this by editing preferredMaxWidth() in /usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/code/layout.js: 

function preferredMaxWidth() {
    if (tasks.iconsOnly) {
        if (tasks.vertical) {
            return tasks.width + verticalMargins();
        } else {
            return tasks.height + horizontalMargins();
        }
    }
 
//    if (plasmoid.configuration.groupingStrategy != 0 && !plasmoid.configuration.groupPopups) {
//        return preferredMinWidth();
//    }
 
    return Math.floor(preferredMinWidth() * 1.6);
}
