[Kernel-packages] [Bug 1756997] Re: plasmashell leaks memory uncontrollably

This is at the level for me that within a day or two after (re)starting it, it is taking up all of my 12 gigs of ram and my my swap space engages and my system starts thrashing to the point that it takes minutes to get to a console to killall plasmashell. If I'm not sure if I'll even get to that point, I do SysRq+F (Sometimes it locks up completely -- presumably due to a kernel panic -- if I don't catch the extensive thrashing before too long, but that's a secondary issue.) This problem began several months ago (I was sort of expecting someone would quickly patch it, so I lived with it for a bit) so unfortunately I can't point to a specific version number. I did run apport-valgrind on plasmashell (output to be attached), which is what implicates the nvidia drivers. Happy to provide any additional information requested or to try other versions of these applications.

[Kernel-packages] [Bug 1684240] Re: Lagging square around mouse pointer
According to this bug: https://bugs.kde.org/show_bug.cgi?id=382812 the issue is not plasma-workspace, nor sddm, nor nvidia, but xorg and according to it the bug has been fixed in xorg. Closing now, if the bug still persists please reopen with details on a supported release. ** No longer affects: nvidia-graphics-drivers-375 (Ubuntu) ** No longer affects: nvidia-graphics-drivers-384 (Ubuntu) ** Bug watch added: KDE Bug Tracking System #382812 https://bugs.kde.org/show_bug.cgi?id=382812 ** Changed in: plasma-workspace (Ubuntu) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to nvidia-graphics-drivers-384 in Ubuntu. https://bugs.launchpad.net/bugs/1684240 Title: Lagging square around mouse pointer Status in plasma-workspace package in Ubuntu: Fix Released Bug description: (This can also be an nvidia related problem) Mouse pointer behaves as if it has an invisible square attached to it. This square covers some area next to the pointer, but it is not always clear exactly where (a link to a screenshot is shown below, please note the white square with some text from the previous webpage displayed in that window). This makes selecting text difficult, as one never knows where exactly the selection ends. Also, scrolling in some windows becomes problematic, as the pointer shadows a part of the scrollbar. When a text is being typed, one needs to make sure that the pointer is parked sufficiently far from the text (so, to make a long story short, this is very annoying). This behavior does not depend on the choice of the cursor theme.

I cannot reproduce this with intel graphics.

Steps: 1. Log in with Plasma on X11 2. In System Settings select Workspace Behaviour > Virtual Desktops 3. Create a layout of 2x2 (two rows with two desktops each) 4. Put the system to sleep 5. Wake the system up and enter your credentials 6. Switch to a different desktop to the one you are wither with a key combination or clicking on it on the taskbar. Outcome: A black screen will be shown instead of the desktop. If you try to go back to the original desktop you will still have a black screen. Expectation: For the system to switch virtual desktops without any issues. Workaround: 1. Change virtual terminals using Control-Alt-F4, for example. 2. Change back to the GUI virtual terminal with Control-Alt-F1 3. The graphical interface is restored and you can switch between virtual desktops without problems. Alternatively I imagine that removing virtual desktops would work, but that reduces functionality. Things I tried: 1. I purged all the nvidia drivers and installed the last version 535. It worked briefly but it quickly reverted to the same issue. 2. I have tried login using Plasma on Wayland and I can't reproduce the problem.

Problem: a black screen freeze occurs by suspend-resume process Ubuntu version: Kubuntu 19.10 default plasma, or the backported 5.17 Kernel version: default 5.3.10 or the mainline 5.4.0rc3 xserver-xorg-video-amdgpu: 19.* or the newest from git, the 18.0.1-1 works well This freeze can be reproduced only if opengl 2.0 or 3.1 compositor is enabled in Plasma settings. Xrender is OK however I don't like screen tearing. On Ubuntu 19.10 Gnome desktop (X based) this doesn't occur even if the Gnome's compositor is enabled. (I don't know what is the default one there but I haven't disabled it) I think this is a Kwin / amdgpu driver related bug because of the differentiation. These can be fixed even in Kwin/opengl compositor not just in the amdgpu driver or in kernel. One possible solution: disable opengl compositor by suspend and re- enable it after login. Use fe.: Xrender before login / before the system restored from suspend. For Ubuntu's maintainers: Couldn't be this problem solved by a downstream solution? Maybe a proper script could be enough by resume and by suspend. There are a lot of bugs like this reported in freedesktop bugreport and the developers haven't got enough time for fix them fast enough.
