I've noticed that my desktop frequently locks up recently. I can only get going agian by pressing Ctrl-Alt-Backspace a couple of times and logging back in. Is this a new "feature"? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Are you sure you are up to date on KDE updates? This use to be common, but its been months since this has happened. You can usually do Alt-F2, then type into the little window: killall plasmashell & kstart plasmashell You usually don't lose any work in progress. This has been going on since 2013. There are many long bug reports on this. Some attribute it to a transparent window popped up by a program that subsequently crashed, leaving the window hanging around capturing keystrokes and mouse clicks. Others attribute it to sddm. (I know I switched to lightdm and these problems went away, but that was on a different distro. I keep up with KDE changes, (or as many as opensuse sends my way) and haven't seen a occurrence of this for a long time. -- After all is said and done, more is said than done. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I am familiar with that and even wrote a script to do it. However, this problem is much more recent and pressing Alt-F2 doesn't do anything. The only thing that gets me out is to shut KDE down entirely and log back in. However, it's only the desktop that locks up. Any running apps keep running. And I can even use NoMachine, from another computer, to access a Windows 10 virtual machine, even though I can't switch to it from my Linux desktop. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

BTW, I still have to do that, in addition to this newer problem. There are also other KDE issues on my ThinkPad, where I lose multiple desktops and also the top bar in open windows, where the X is for shutting down the app. When that happens, I have to use Alt-F4 to close. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Actually, yes. I discussed this a couple of months back and, IIRC, there was a bug report. Someone here provided some commands to restart plasma shell.

so spend some of your time and help others help you. what bug report # discussed? restarting plasmashell is a work-a-round, somewhat like a round tuit. you have a problem, provide information about when it happens, what is running, what seems to make it happen, what *you* have tried that helps or does not help. -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri Registered Linux User #207535 @ http://linuxcounter.net Photos: http://wahoo.no-ip.org/piwigo paka @ IRCnet freenode -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Just to add my two cents to this topic.... I had this same problem in another distro, as did many people on that distro at the time. Switching from sddm to lightdm seemed to solve it. Install lightdm and either the lightdm-kde-greeter or the lightdm-gtk-greeter then systemctl enable lightdm.service systemctl stop sddm.service start lightdm.service systemctl disable sddm.service Then reboot to see that it all works. This solved it, and some where along the way since that time. KDE subsequently found and fixed the problem which turned out to be some invisible remnant of a crashed window overlaying the screen capturing mouse clicks and keystrokes. It was also more common among users of dual monitor systems. That distro is running Plasma 5.10.2 and KDE Frameworks 5.35 and Qt 5.9.0, all of which are much much newer than I have on Leap 42.2 which shows Plasma 5.8.6 and KDE Frameworks 5.26 and QT 5.6.1 Hint: run kinfocenter -- After all is said and done, more is said than done. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

There is a significant amount of time and number of fixes between those versions. IIRC Qt 5.9.1 is out as well.

What I have found, James, is that at random times some app. I am using stops working and I get the (error) message that 'kwin has stopped working. Do you want to restart application or want to report this problem' -- or words to this effect. From memory this occurs when I am closing the app.. I have never experienced this in all the many years I have been using openSUSE until now in Leap 42.2. As I said, this is a random occurrence and not reproducible on demand. If my memory (such as it is) serves me right, I did look in the logs but didn't see anything to indicate such a failure of Kwin. Oh, I am using KDE as the desktop, using the nVidia driver which I always compile myself, and this is on a desktop computer (16GB of RAM, 8-core AMD CPU) and not a laptop (which I rarely use).
