ok on my system. Does the file /usr/share/mime/inode/directory.xml exist? It's from the package shared-mime-info. CC:

davidwhodgins The file existed, but was not readable by "other". I made it readable. Now things are worse. It I run systemsetting5 the mouse cursor dis appears. If I do alt-ctrl the SystemSetttings window disappears, then comes back with a black border, and in a few seconds the mouse cursor reappears, but nothing works (ie clicking does not work) for a while. Then it does, and clicking on Applications causes the window to disappear and segfault occurs. $ ll /usr/share/mime/inode/directory.xml -rw-r--r-- 1 root root 2543 Nov 25 17:47 /usr/share/mime/inode/directory.xml So it should already have been readable by other. The question becomes how did it lose that permission, and what other files now have the wrong permissions or other attributes. Any idea how it lost the permission? If you don't know, then the options are to go through the output (run as root) "rpm -Va" to figure out which ones have the wrong attributes (see "man rpm" and search for "format of the output" for what the characters in the 9 columns mean) or to re-install the system. Nope, no idea how. But a permission should not cause a segfault, no matter what. I've done rpm -Va, and looked at M, the mode change from installation, and cansee nothing there that could explain the problem. Does anyone know what program is run when one clicks on Applications under SystemSettings? 4435 dave 20 0 232M 7272 3384 S 0.0 0.0 0:00.22 │ │ └─ bash│/bin/bash 27104 dave 20 0 1264M 145M 107M S 0.0 0.9 0:00.93 │ │ ├─ systemsettings5 27109 dave 20 0 1264M 145M 107M S 0.0 0.9 0:00.01 │ │ │ ├─ systemsettings5│QXcbEventQueue 27110 dave 20 0 1264M 145M 107M S 0.0 0.9 0:00.00 │ │ │ ├─ systemsettings5│QDBusConnection 27111 dave 20 0 1264M 145M 107M S 0.0 0.9 0:00.01 │ │ │ ├─ systemsettings5│systemset:rcs0 27112 dave 39 19 1264M 145M 107M S 0.0 0.9 0:00.00 │ │ │ ├─ systemsettings5│systems:disk$0 27117 dave 20 0 1264M 145M 107M S 0.0 0.9 0:00.04 │ │ │ ├─ systemsettings5│QQmlThread 27118 dave 20 0 1264M 145M 107M S 0.0 0.9 0:00.00 │ │ │ └─ systemsettings5│QQmlThread It's all part of systemsettings5, so "rpm -q -l systemsettings" shows which files are part of it, though as a kde plasma program it will also use various qt libs. The system is rapidly decaying. The mouse arrow will disappear for seconds at a time (up to 10 sec). If I click on the clock at the bottom right of the taskbar, up will come a black screen with white blotches on it-- certainly not a calendar. At times the popup explanations of an icon will have lost many of their letters (Bluetooth will be Bl t o th and all of the icons on the bottom right will display the same kind of nonsense. windows will disappear for 5 sec at a time and then reappear I tried to use xfce instead of plasma, but all I got was a black screen with a mouse cursor on it. I had to do alt-ctrl-F2 log in and killed the xfce program to recover. And this all seems to be getting steadily worse. Logging in has big pauses in it, and the desktop may flash. It is hard to imagine this as a hardware problem. I have no idea how to track this down, but it is making this computer almost unuseable. Can you boot a live iso to see if it works with that hardware? I tried another user on the system, and they also have problems. I tried the live distribution briefly and it seemed not to have the problems. But that may be that I did not try long enough ( although the problems start showing up pretty quickly. It really seems to be a graphics problem-- maybe the graphics driver, maybe the kernel modules. (I have also used my spare / system to reinstall the un-updated Mga 8 on it, and again did not seem to have the problem. Of course it is a much stripped down version since I have not insatalled all of the programs which I have on my system onto that one. I have installed chrome, and it seemed to be fine. Very strange. I did a new installation ( without update) of Mga8 onto a separate partition. That installation has none of the problems. while the old installation keeps having the same problesm-- getting worse if anything. It really seems that the updating of the system is causing the problems. So it does not appear to be hardware, but software. The fresh install also does not have the problem with the sddm flashing back to the console for 2 seconds about 5 seconds after it first displays. Ie almost all of my problems seem to be caused by the same thing. I also confirm that this does not happen on my system, fully up-to-date including Plasma. It is curious how you suffer so many problems unique to yourself. Dave's suggestion to try the Plasma Live ISO was sound: you did, and it seemed not to have the problem; which, when it happens, is immediate. The problematic system seems rather sick. For "almost unuseable" read "unuseable". Has it ever worked properly? Can you describe its degradation? CC:

lewyssmith One big difference was that I upgraded and MGA7 install then. as I recall it did work more or less OK at the beginning. There were two weirdnesses which began very near the initial upgrade-- one was that sddm logon screen would show for about 3-5 sec, but then flash to the console, and then after about a second show the console for about 1 second,before I could enter the password for myself. The second was that I would get lines on the screen, especially if chrome was running, where pixel lines were displaced. I have seen the latter happen on a konsole screen visible peeking out from the sides of Chrome screen. But more recently things have degenerated badly (eg this bug report). So far I have not seen either the sddm flashing or the other problems mentioned here on the new instalel. But I have not updated it. See if turning off "Enable compositor on startup" in systemsettings5 under Hardware/Display and Monitor/Compositor, and restarting the system has any effect. It was already off (uncheckmarked) Weirdly enough things are getting worse and worse in the version which was the update to Mga7. Meanwhile, the new installation is still working, except for the pixels on lines being messed up.) Have you installed updates from the testing repos? There are some there that haven't been assigned to qa yet, that in their present form cause problems. On one install where I have the testing repos enabled as updates repos, in /etc/urpmi/skip.list, I currently have ... lib64wx_baseu3.1_5 lib64wx_gtk3u_core3.1_5 Nope. just the release and the updates for core, nonfree and tainted. @ w unruh Maybe this report should be closed as OLD? It seems an issue that only affected one Mageia installation of no one else than you, there was an unexplained permission issue, too, and that installation became more and more unstable, didn't it?
