[SOLVED] Lost MATE after trying KDE

c3kay · 2015-05-27 04:04:54

So I thought I'd try out KDE5, but it turns out that was a huge mistake, because now I can't boot into MATE. KDE turned out not to be for me, but after I logged out and moved back into MATE to remove it, I was presented with a blank screen and a spinning cursor. I get no response except by ctrl-alt-F1 to login via tty. I can, however, after some experimentation, boot into Enlightenment, Cinnamon, LXQt, Gnome, Budgie and XFCE. Just not MATE, which was my only desktop on the desktop PC.

And I really like MATE. XFCE is currently running, but I don't like it as much as MATE. Infuriatingly, it's obviously faster, but I still prefer MATE.

I've made sure I've properly cleaned out the remnants of the other desktops while preserving what I need to keep running KDE apps like Okular. I've removed and reinstalled MATE. I've removed them all, removed LightDM and the greeter, and used SDDM. Same result, only with SDDM I couldn't bring up the terminal when it failed.

The only error I thought was strange appeared in the logs that said mate.screensaver Couldn't get presence. But now I look back through the logs, I can't find it again.

Can anyone help? I can post logs, but right now I'm not sure where to being, except that I've excluded it being anything to do with LightDM or being able to boot into a DE, because it only happens with MATE and I've used two different DMs.

I added MATE to .xinitrc and started it from a terminal. This time I didn't get a blank screen, I got my actual desktop wallpaper, and there was no busy cursor, but I got an actual mouse pointer.

Okay, I got it running by uninstalling MATE and then installing just the mate-panel base package. I'll see what happens tomorrow if I install the rest of the packages and extras.

I don't know why this has happened yet, but if anyone can shed some light on it, I'd appreciate the help.

Though I can't help with your specific problem, I can offer a tip. When trying new WM/DE apps, I always create another user on the system and test with that user. This way if I modify something, my original user's settings doesn't get turfed. If I like the new environment I can then use my regular user and set things up/copy configs as I want.

Hi Matt. Thanks for the tip. I have no idea why it did this, and despite having the same setup on Fedora (albeit with GDM) I haven't had the issue with MATE. I also couldn't log in using another user, although I don't know if it would have had this effect if I'd set up the user to use the new DE by default.

Anyway, I installed each package in mate individually. The problem turned out to be mate-themes. If I have gtk-engine-unico installed, then post-KDE it hangs and gives me the spinning cursor. If I remove gtk-engine-unicode then it completely blanks my screen out.

Given I've lost my themes, I should probably head over to MATE forums and see if anyone can help. I don't think this is solved... I just think I've managed to isolate the problem and replicate it. It's strange because I didn't touch MATE, and hadn't uninstalled KDE before it failed to start.

I tried installing mate-themes-extras, which gave me functionality back. The themes weren't being applied properly though, so I ended up stripping everything extraneous I could find. MATE themes went, and so did GNOME themes, until I could reboot into a completely bare MATE. qtcurve went, as did everything KDE from my system. Fortunately the only KDE app I use is Okular, so it wasn't a bind to strip out Okular and then reinstall it when I was sure things worked.

Then I reinstalled all the themes and icons from scratch. And lo, I have my MATE desktop back.
