I have been using e17 for about a year. I haven’t encountered any bugs, and it’s definitely stable enough for daily usage. On upgrading e17 earlier this week to 0.17.6, I found the monitors to be handled separately. I considered this to be a regression in the software. I installed the upstream development version 0.18.7, since it was in the Portage tree to see if it fixed the problems. Other people had the same multiple monitor or dual-monitor problems with e18. I played around with the settings to no avail. Installing 0.17.5 again by editing the 0.17.6 ebuild didn’t help.
I decided to install the old 0.17.5 ebuild which is no longer in the Pportage tree. Upon close examination, EFL (Enlightenment Foundation Libraries) in the recent ebuilds replaced the separate packages used in the 0.17.5.ebuild.
In the 0.17.5.ebuild:

In the 0.17.6.ebuild:

I decided I had enough of the split screen methodology. One reason people don’t switch software is because they have to change the ways they interact with them. In my case, interacting with each monitor separately would lead to productivity loss while learning the new methodology and in the future. For example, the taskbar in the newer versions only show windows from one monitor. If I use two taskbars, I would have to keep track of where I put each window. User interfaces should get out of the way as much as possible so that users would not have to perform such unproductive chores.
Time to download the old ebuilds and rollback e17.

The general procedure is to download old ebuilds as necessary and remove packages that block other packages from being emerged. I went on to reinstall terminology, e17’s native terminal.

Finally, to prevent future upgrades from undoing the work, mask newer versions of e17 and terminology in /etc/portage/package.mask/e17

After installing e17 on Gentoo and a few applications, I noticed that some of the applications in the menu had icons while others did not. The same icons were missing in the IBar and other places. At first, I checked the wiki page on e17, it suggested to install evas_generic_loaders with SVG support. Contrary to what it suggests, evas_generic_loaders does not affect menu icon display it is used for tooltip previews in the file browser.
The way to set is to navigate to Settings -> All -> Look -> Application Theme and open the Icons tab. Once I selected Gnome, all the icons appeared. “Enable icon theme for applications” was already checked by default. If you do not see Gnome icons in the Icons tab, make sure you have installed x11-themes/gnome-icon-theme if you’re using Gentoo.

I just started using e again yesterday after installing Sabayon. With the most recent version, it has become the most productive desktop environment I’ve every used with features like:

• automatic cursor center on new windows
• focusing of windows under cursor, allowing typing and clicking without raising
• coupled with transparency on unfocused windows

I also updated my performance tweaks for Sabayon, so it’s the best browsing experience, too, with right click link mapped to open foreground tab. So I got to experience e17 as it was released today after about 7 years of development.
