All starts with the Xid error, which breaks X and freezes, slowing down input for 8.5 minutes (wouldn't open tty either) until finally restarted the session as prompted via kbd, killing the hanging process (kodi-xbmc). No thermal throttling before, during or afterwards. Temperatures were all normal throughout. It showed the process manager after 6 minutes or so, still freezing upon any input.

Since Manjaro was first installed on this machine (2018-08-27, 10:02) that is the first ever freeze I've experienced after so many updates and new kernels on the stable rolling branch. I've always used Kodi during this time. Only thing changed was updating to the latest kernel and packages from the repo, two days earlier.

crash log from kodi, showing VDPAU failing to initiate at the same time:

does going back to 5.0 stop this from happening?

can you also post:

BIOS only has the option to choose between "Auto" which prioritises the device that's being used and "IGD" where the Integrated Graphics Device is favoured.

you have more than 1 xorg configuration which can/usually causes issues

post:
ls -laR /etc/X11

if yes then use 5.0 or 4.19, etc...

I thought that having /etc/X11/xorg.conf.d/20-nvidia.conf is the correct way of changing any settings with the proprietary driver (https://wiki.archlinux.org/index.php/NVIDIA#Configuration). Looking at the files, I can see they have all been generated a while ago. Generating new ones does not make any changes to them as I have confirmed with nvidia-xconfig and NVIDIA X Server settings. However, I've also just noticed the chosen method shown here doesn't even mention using nvidia-xconfig: https://wiki.manjaro.org/index.php?title=Configure_NVIDIA_(non-free)_settings_and_load_them_on_Startup#Configure_The_Resolution.2FRefresh_Rate
I understand the idea of having only one Xorg config file set to /etc/X11/mhwd.d/nvidia.conf but what about nvidia-settings --load-config-only exec $(get_session) into .nvidia-settings-rc. Isn't that file being rewritten every time you make any changes from the NVIDIA X Server Control Panel as in resolution, OpenGL settings, etc.

In regards to the kernel, I'll keep it for now at least until I manage to replicate this issue, because if it isn't down to hardware or configuration, then it's a kernel incompatibility with the drivers and correct me if I'm wrong, but Manjaro uses its own patched kernels.

Thanks for your help!

mhwd creates a configuration when drivers get installed, it gets stored in
/etc/X11/mhwd.d/nvidia.conf

which then gets symlinked to /etc/X11/xorg.conf.d/90-mhwd.conf

video configurations in /etc/X11/xorg.conf.d are what gets used and you have both 90-mhwd.conf and 20-nvidia.conf . either pick one and delete the other or delete both and let mhwd re-install drivers and a new configuration will be created
sudo mhwd -i pci video-nvidia

you can also use nvidia-xconfig to generate a new configuration but be sure to specify the output path, otherwise it defaults to /etc/X11/

either way, only leave 1 video .conf file in xorg.conf.d

After removing all configuration files and reinstalling the driver, upon first reboot, mhwd failed to detect a monitor and active gpu and stalled on a blank screen until I unplugged the hdmi/dp cable and plugged it in again. Then it detects it and continues normally, writing the config and booting to login screen. Not sure if that's due to the "Auto" active gpu setting in BIOS or it happens on all systems. I don't have another machine running Manjaro to test it on. Otherwise all is working well, excluding Kwin's latency but that will supposedly be fixed/reduced in future Plasma builds.

How are you dealing with it atm? Have you tried the new fix?
https://www.phoronix.com/scan.php?page=news_item&px=NVIDIA-KDE-High-CPU-Fix
https://phabricator.kde.org/D19867

export KWIN_TRIPLE_BUFFER=1
export __GL_YIELD=USLEEP
export __GL_MaxFramesAllowed=1

I couldn't see any difference. Not sure it's actually exported when set from /etc/profile.d/kwin.sh.

https://github.com/tildearrow/kwin-lowlatency This is actually working but has to be implemented from Plasma's developers because if used separately, is bound to cause more harm than good..

im not, everything is peachy here. i dont use KDE anymore, i went to openbox after kde and loved it, then i went to awesome wm and it's exactly as the name implies. i dont see myself switching anytime soon.

back OT, so removing those configs and reinstalling drivers took care of the issue or it's still happening?

if it's still happening, switch kernels. i know i had issues with 5.1/nvidia that i didnt have with other kernel versions. another post earlier today with nvidia/5.1 and problem fixed by going back to 5.0

hasn't happened yet, but if it does, I'm switching too :smiley:

JK I'm way too conformed to Kwin/Plasma to switch to anything else at this point.. But then again, I said the same thing about Gnome a decade ago. It's a WIP, it could go either way.. One could only hope devs take it the right way.

i dont dislike kde or gnome, i used kde for a while and of course it has it's issues but in the end i uninstalled it not long after using awesome as my primary setup. i had 3 separate installs, sometimes more of different setups at any given time but only awesome i felt like i had exactly what i needed/wanted, it's all personal preference

It continues freezing with the new KDE framework and Kwin, and the latter is the culprit. I've tested on three different kernels, also with the newest available non-free Nvidia drivers 430.14. Regardless of settings and configuration, vsync is always a bit broken with the new Glx swap buffer "fix" implemented in Kwin. When "Force composition pipeline" setting is active in nvidia-settings, there's no tearing but the abuse of the buffers is breaking OpenGL as seen here May 27 16:50:10 george-pc kwin_x11[9321]: kwin_scene_opengl: OpenGL 2 compositing setup failed
It freezes the desktop until ctrl+alt+backspace input is registered and gets executed. Easiest way to force a freeze is by exiting an application which suspends compositing. Switching between tty sessions works as well. If you are patient enough to just wait for the renders to decide what to do, it switches to xrander with graphical artefacts and lacking kwin shortcuts. In other words, it eventually kills kwin. There are diagonal green lines glitching (///)when new windows are opened and drawn, Alt+tab hangs the system and so on.

Now, following bugtracking, it has been suggested that the new code is not playing nice with iGPU enabled systems with a master PCIe GPU. Mine cannot be disabled from BIOS, therefore the only solution other than downgrading plasma frameworks & kwin, was to install kwin-lowlatency from AUR. It interacts with the same code but in a way that doesn't break X. It makes animations butter-smooth at no cost on performance. There are no freezes whatsoever. This and Compton's rendering method are the only things that work for nvidia cards owners right now. I understand Wayland & AMD is the way forward for Linux, but M$ Windows CAN NOT be the way back for nvidia users..

Hopefully KDE devs can make a fix or adopt the existing one. Legacy solutions to tearing aren't working anymore, since the update. Kwin Compositor's own Vsync works when compositing is enabled, albeit introducing latency and micro-stutter while actual vertical synchronisation is inconsistent, but it mostly ruins performance and the running of full screen applications, especially games. Using Force composition pipeline gives a more decent vertical sync on desktop with less stutter and more latency, but freezes X and adds an extra buffer or two, to make your GPU's life even harder. I really don't like where the developers are going with this. It has been a well known issue for the last half a decade. Sure, Nvidia's corporate interests are what makes it a painful and hopeless cause, but devs need to combine efforts if they wish to fix it, instead of pushing their own agendas. If there is an actual working way to fix something, with a ready compiled code and the people in charge of implementing it simply choose to ignore it, then we are lost.

theres been some recent issues regarding optimus setups and kde/plasma. read the linked issues from this post (towards the end). does disabling compostiting stop this behavior from happening ?

yeah, but disabling compositing would also stop me from using Plasma. :rofl: I mean, without it, even the taskbar is not active. You look at the clock thinking you still have enough time to get to work.. Then before you know it, your workplace calls your next of kin to ask if you're alive.

i meant that as a diagnostic step. if compositor is disabled and problem goes away, then the problem lie in the compositor. that reasoning isnt definitive but it's surely helpful to determine a starting point

oh absolutely, no question there. Compositing disabled or not, OpenGL's functionality is ruined and so is VDPAU.

i would start by searching these errors on related issue trackers or google. another long shot, you could try deleting /home/george/.Xauthority logout and back in and test again.
