VirtualBox

• I use the default package from openSUSE
• for USB problem, check http://forums.opensuse.org/showthread.php/493771-Can-t-attach-USB-device-to-VirtualBox

Copy the file /usr/lib/udev/rules.d/60-vboxdrv.rules to /etc/udev/rules.d/, open it with a text editor, and remove the leading '#'s from the last 4 lines below the comment in line #2. This is needed to give you the needed permissions, but is disabled by default in the openSUSE package because of security concerns. It should work then after a reboot.

• VirtualBox package from oracle https://www.virtualbox.org/wiki/Linux_Downloads

my widget looks ugly, have to install package libreoffice-gnome

Pimp my Firefox

on HiDPI display, the ui element is very small. Fix by following option in about:config

[code] layout.css.devPixelsPerPx=2 [/code]

also we need to add font size to ~/.mozilla/firefox/XXXX.default/chrome/userContent.css [code lang='css'] @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* set default namespace to XUL */

• {font-size: 14px !important; } [/code]

I love my KDE in black but firefox won't agree with this. Create this file ~/.mozilla/firefox/XXXX.default/chrome/userContent.css

[code lang="css"] input { border: 2px inset white ; background-color: white ;
color: black ;
}

textarea {
border: 2px inset white ;
background-color: white ;
color: black ;
}

select {
border: 2px inset white;
background-color: white; color: black; }

input[type="radio"], input[type="checkbox"] { border: 2px inset white ; background-color: white; color: ThreeDFace l }

|::-moz-radio { background-color: white; }

button, input[type="reset"], input[type="button"], input[type="submit"] { border: 2px outset white; background-color: #eeeeee; color: black; }

body { background-color: white; color: black; display: block; margin: 8px; } [/code]
