Missing Maximize / Minimize in Gnome

Gnome 3 continues to be abhorant. Not only can I not get to a terminal easily anymore, but there’s no maximize / minimze button on windows? Who designed this and have they used graphical user interfaces for more than a few minutes / hours? Anyway to turn this basic functionality back on using Fedora try (thanks to this thread):

sudo yum install gnome-tweak-tool

Then search for ‘tweak’ in the Gnome 3 Applications menu, open ‘tweak tool’ app and click the ‘Windows’ tab and enable the titlebar options as follows:



VNC to Linux PITA

A stubborn or short-sighted developer, it seems, is the cause of many people’s grief and effort to get VNC working to a linux box from any of the standard VNC clients (tiger, realvnc etc.). As of Fedora 19+, the code has changed in vinoserver, the default linux VNC server, such that the encryption mechanism is incompatible with ALL standard VNC viewers. You’ll see something like ‘No matching security types’:


The only option for the average user is to disable encryption. Pretty stupid, but I’ve seen this before. A developer ‘David King’ says “My code is right, everyone else is wrong.” and marks a bug as ‘NOTABUG’. How sad. Anyway, until someone else can take a look at this from another perspective, make sure you only use VNC to linux on a secure LAN environment and then do this:

gsettings set org.gnome.Vino require-encryption false

Make sure you do it as standard (not sudo) user. Sucks to disable security – but if complexity is a barrier to entry, that is the result. 🙁

Mime types with Gnome Commander

One of the things that mime types are used for is to specify the default program to associate with a file extension. Unfortunately, this is currently broken with Gnome Commander (at at v1.2.8.17). To fix it, you’ll need to add a line to the following file:


Create that file if it doesn’t exist and add [Default Applications] on the first line. Then add the mime type (as shown on the gnome commander error dialog when you try to open your file) and specify the program to use. For example, for PNG file extension you might want to use Eye of Gnome (eog) so you’d add:



Save the file and you’re done. If it still doesn’t work, you should check this thread on the Ubuntu forums. Tested with Zorin OS 9. Hopefully this is fixed in a future version.
