For upgrading/downgrading your distro you really need to find an appropriate forum/list for your distro and ask them. This is a kde list, not a mint list, and unless someone here happens to use mint and can respond, you're unlikely to get distro-specific help like that, here. However, we might be able to help with the kde problem. In fact, you may be experiencing a problem I've had for some time, that altho I've not been able to really fix, I've been able to successfully work around. =:^) If it's not the same problem, it appears to be a similar one. The first thing to figure out is whether plasma (the normal kde desktop) is running at all, possibly reset to some default, or if it's not even running. You say alt-f2 works and you can run stuff from it, so that's what we'll use. First, try this: kquitapp plasma-desktop If your desktop disappears or changes, that means plasma was running, but just reset to some default, which is the bug I've been running into here. If nothing changes, that means plasma wasn't running at all. Next, try this: plasma-desktop Hopefully that'll restart your desktop, regardless of whether it was running and you quit it with the above, or if it was not running. If you get a good kde desktop back, you're in business. However, here it restarts with the default desktop again, not my customized desktop. But, after a restart, my old desktop activities are available again -- I just have to switch to them. (Before a plasma restart, all it has is the default desktop/activity, it doesn't show my customized activities so I can't switch to them until I restart plasma-desktop.) The other possibility is that it's so screwed up that it'll try to start, possibly flashing something, and crash again. That's probably a config issue, which means troubleshooting your config. Meanwhile, presumably you're logging in as your normal user, with an existing config. What happens if you create a new user, without an existing and possibly corrupted config, and login to kde as that user? Obviously that won't give you your customized config, but does it give you a default uncustomized kde/plasma config, or does that one crash too? If a new "clean" user config works, then you know the problem is in your config. (With the problem I've been having, a new user has the same problem, so it's not something in my normal user's config that's corrupt.) That should get you started. Once you try that and reply with the results, we can go from there. -- Duncan - List replies preferred. No HTML msgs.
