Fedora 24 Gnome Shell Window Size

To make the default title bar smaller in Gnome 3.20 on Fedora 24 create the following file and restart with "killall -3 gnome-shell".
$ cat ~/.config/gtk-3.0/gtk.css 
/* shrink headebars */
headerbar {
    min-height: 24px;
    padding-left: 2px; /* same as childrens vertical margins for nicer proportions */
    padding-right: 2px;

headerbar entry,
headerbar spinbutton,
headerbar button,
headerbar separator {
    margin-top: 2px; /* same as headerbar side padding for nicer proportions */
    margin-bottom: 2px;

/* shrink ssd titlebars */
.default-decoration {
    min-height: 0; /* let the entry and button drive the titlebar size */ 
    padding: 2px

.default-decoration .titlebutton {
    min-height: 16px; /* tweak these two props to reduce button size */
    min-width: 16px;

gnome-shell super maximize


  • This is a two way toggle. Type it once to "super maximize". Type it again to un-"super maximize".
  • In gnome-shell this will maximize the currently focused window to the point that its titlebar will not be seen.
  • It will only do this to the Terminal (including xterm).
  • I've hit this by accident a few times but didn't know how to undo it, so I'm logging it here should I forget.
  • It's not listed on Keyboard Shortcuts or my first 5 Google results.

synergy dekstop sharing

I bought access to Synergy from the company supporting it because I've been using it for years and they deserve a few bucks. I use EPEL but don't want it clobber the version that I download from Thus, I have the following in my epel.repo:

$ sudo head /etc/yum.repos.d/epel.repo
name=Extra Packages for Enterprise Linux 7 - $basearch

This is another one of those posts I do to remind myself about what I did.

Burn RHEL7.1 ISO from RHEL7.1

I ran the following on a RHEL7.1 system to make a RHEL7.1 bootable ISO.

[root@box iso]# ls -lh rhel-server-7.1-x86_64-dvd.iso 
-rw-rw-r--. 1 qemu qemu 3.7G Mar 17 11:09 rhel-server-7.1-x86_64-dvd.iso
[root@box iso]# 

[root@box iso]# growisofs -dvd-compat -Z /dev/cdrom=rhel-server-7.1-x86_64-dvd.iso 
Executing 'builtin_dd if=rhel-server-7.1-x86_64-dvd.iso of=/dev/cdrom obs=32k seek=0'
/dev/cdrom: "Current Write Speed" is 8.2x1352KBps.

I think growisofs has a slightly confusing name and an odd syntax.
