There is no global setting like the zoom scale factor in Unity, but you can follow these steps to achieve most of it:
1. Set a Custom DPI setting
Open a terminal with CTRL+ALT+t and enter
In "Appearence"->Fonts-> "Custom DPI Setting:" set this to 192 (instead of the default 96).
Log off and on again to accept the new settings in all windows.
2. Adapt Theme and settings
Set your panel size to a height of 48
xfce4-settings-manager->"Settings Editor" (
- in section
xfce4-desktop (create an entry if it doesn't exist)
desktop-icons/icon-size Type Integer and set it to 128
- in section
CursorThemeSize to 48
Or use the commandline:
xfconf-query -c xsettings -p /Gtk/IconSizes -s "gtk-large-toolbar=32,32:gtk-small-toolbar=24,24:gtk-menu=32,32:gtk-dialog=88,88:gtk-button=32,32:gtk-dnd=32,32"
- Download the Widepanel Appearance
- In the File Manager thunar adapt the preferences:
- Set Iconsize in the sidepanel to "small" or "normal"
3. Adapt Firefox
see: Adjust Firefox and Thunderbird to a High DPI touchscreen display (retina)
(or use Chrome, which works fine since Version 41.0.2272.76 Ubuntu 14.10)
4. Increase font in Pidgin
There is a plugin you can install
sudo apt-get install pidgin-extprefs
Then you can increase the font in Plugins->Extended Prefs
5. Create starter for applications that still don't scale
Some applications still don't obey the global scaling (mainly java) for those few applications you can create a starter to only Fix scaling of java-based applications for a high DPI screen
