I've been giving Linux Mint a shot.
Now, OpenSUSE is still my primary distro (for now -- more on that in a minute), but I've kept my old Kubuntu drive onhand, originally because I've got OpenSUSE on a 128GB SSD and could use another drive with some extra storage, but over time I also learned how useful it is to have a second Linux distribution installed for those times OpenSUSE craps out. (More on that in a minute.)
So when I swapped in a new drive, I put Mint on it, as that's a rapidly growing distro and the one a lot of disgruntled users seem to be checking out since the releases of Unity and GNOME 3.
My first reaction is that the default installation looks pretty and clean. 'Cept maybe the menu, which is too busy.
And my next reaction is that there's a pretty good complement of programs installed...up until I open the terminal and find that vim is not included. Yes, I realize it only takes a minute to install, but I'm one of those guys who is immediately suspicious of any distro that doesn't come with vim out of the box.
My next reaction is my usual complaint about GNOME: it's just not configurable enough, and the various configuration options are spread across too many different places.
You can choose themes in five separate categories -- Cinnamon Themes, Window Themes, Cursor Themes, Icon Themes, and GTK+ themes -- and you can mix and match among those, which is good. But I don't see anything as simple as a color chooser. Your colors are determined by your themes. Want your panel to have a widget style like Nightlife but a blue highlight on the active program like in Blanka Teal? Tough; can't be done. Want to use Adwaita for the window theme but not want the active titlebar to be the same fucking color as inactive title bars? Can't do that either; if you're going to want a colored titlebar you're going to have to go with one of the more oldschool/minimalist window styles like Atlanta or Metabox. (Or hunt for themes online, a thing which I don't really ever do because I find them almost uniformly to be worse than the ones bundled with the DE.) For extra kicks, you can combine the Mint-X GTK+ theme with the Atlanta, Bright, Metabox, or Simple window themes and get a color scheme where the active window title text is white and inactive windows' title text is black.
Oh, and there's also a "keybinding theme" under themes, which is bullshit because keybindings are not fucking themes. This unfortunately seems to be a trend in Mint/Cinnamon -- cramming shit sideways into categories it doesn't really belong in because the designers apparently can't figure out where else to put it. Want to make Mint stop playing a sound at startup? It's under Login Window -> Accessibility. Yes I had to fucking look it up.
Special Bonus: Login Window is one of many settings that does not appear under either the Cinnamon Settings or System Settings panel. Why the fuck are there two different control panels that between them still don't have an exhaustive list of configuration options? Who the fuck knows. That's rhetorical, by the way; I'm sure if I asked some GNOME developer would be happy to point to the usability study that demonstrates this is an awesome fucking idea and anyone who complains about it is objectively wrong and just hates change.
Though speaking of hating change, if you want your taskbar to look exactly like Windows 98-XP's, then Mint is the distro for you. Menu in the lower left, Show Desktop button, QuickLaunch bar, list of open programs, system tray.
Prefer to move it to the top, or change it to a GNOME 2-style top-and-bottom split? Totally doable.
Want to stick it on the left- or righthand side of your screen because oh, I don't know, you bought your computer monitor sometime in the last five fucking years and it has a 16:9 or 16:10 screen ratio? Too fucking bad; you're going to have to find a third-party panel if you want some of that action.
And I think that's my biggest gripe about Cinnamon: the stated goal of the project is to make GNOME 3 behave like GNOME 2. Which is fine if you liked GNOME 2, I guess, but it's ultimately subject to the same sort of design philosophy that users shouldn't have too many choices in how their computers look, feel, and behave (and many of the choices they do have should be hidden in bizarre, inexplicable, inconsistent places).
That's why I'm still a KDE guy -- and it's also why I was still a KDE3 guy for years after the release of KDE4. (4 still hasn't caught up to 3 in some obvious and fundamental ways -- really simple shit like being able to drag a launcher from the menu to the panel. And I'll hand that much to Cinammon: it does that, which puts it ahead of KDE in at least one respect.)
And while I was easily able to find a widget to switch between workspaces, it only has 2 by default, and I can't find anywhere to change it to 4. Maybe it's in there somewhere, or maybe it's not because of Cinnamon's GNOME 3 underpinnings -- I remember that GNOME 3 has an arbitrary number of workspaces, starts with one and adds more as you drag programs to them.
I did see an interface where I could drag a window to another desktop -- repeatedly and accidentally, until I turned off the hot corner. Have I mentioned yet that I fucking hate hot corners? I've got this thing about interface elements that appear by accident, when I'm trying to do something else.
I could probably set up a hotkey to bring up that screen without using a hot corner, and I expect it'd be useful -- and maybe give me some clues on how to have more than 2 desktops. I'll look into it. But binding it to a keypress is not in the same control panel as setting it to a hot corner, and I'm going to have to look up where to find it.
Oh and also the package manager is both slow and hideous.
Anyhow, well, I've been spending rather a lot of time with Mint, mostly because I broke OpenSUSE. It started with an nVidia driver update, but after I reinstalled my kernel it turned into a kernel/init/systemd problem. It's been frustrating as fuck and ate up pretty much my entire weekend. Eventually I just decided to reinstall outright -- and I'll tell that story tomorrow.
Whatever happens, I'll keep Mint around as a backup boot. But the way it is, I couldn't use it as my primary OS -- not without installing KDE on it, at least.
