Last week there was the major update to KDE stretch Plasma5. Since then, KDE immediately freezes when I try to start MC. Then only a a hardware reset is possible.
I know that MC is not made for Debian Stetch. But maybe someone has already a solution for it.
This happens in the VM, in which MC ran with KDE 4 without problems. A new VM with Plasma 5 / Stretch shows exact the same behavior
In no log it gives an indication of this failure
-
The same happens on Netrunner 16 (Plasma 5, based on Ubuntu 15.04, standard install on a real disk partition). It does not happen on SparkyLinux 4.0 XFCE (based on Debian Stretch) or Ubuntu MATE 15.04. Probably MC is incompatible with Plasma 5.
EDIT
I tested v. 20.0.131 for Debian (Jessie) AMD64
-
I tested it additionally with Tanglu 3.0 RC1.
The same: click -> freeze ---> only hardware reset.
What a pity - My laptop is running with Debian Stretch / KDE. I guess I'll have to say goodbye to KDE. :-[ :-[ :o
I hope at some point MC runs with Plasma5.
For me the best desktop environment is KDE. Now I'm going to switch to stretch / Cinnamon.
-
I would guess it's a bug in Plasma 5. Probably some unsupported low level X function.
There shouldn't be a way that one could freeze the OS with a userspace program like MC which doesn't do anything tricky with the hardware.
-
FWIW, I have an Arch Virtual Box guest and if I try to start Plasma 5 with hardware acceleration enabled, Plasma hard freezes on load before I even get to the desktop. It boots fine with hardware acceleration disabled and I can start MC.
The Arch forums are full of people who have total system crashes/lockups with Plasma 5 that seem linked to video driver issues. Two examples (but there are more):

I've never been a KDE user, but I'm not sure how ready for primetime plasma 5 actually is, or it may just be bad luck with a recent mesa regression that makes intel's SNA acceleration particularly unstable for some people see here for details and a workaround: https://www.reddit.com/r/linux/comments/3f5567/the_intel_driver_bug_that_crashes_plasma5_and/

I run debian testing and got round to upgrading to kde5/sddm today, MC works fine on it. Nvidia card in this so I wouldn't be affected by any intel driver bugs.
-
I have now made a separate installation of stretch on a separate drive.
Installed the Nvidia Driver (340.76-5), and then MC21. It happened exactly the same as in the VM. Click ---> The operating system freezes immediately. Only a hardware reset is possible.
