--- Comment #4 from Arjun Menon <arjungme...@gmail.com> --- Hi Martin Flöser, I'll try to look into what I need to do, in order to install debug symbols for KDE/Plasma on Arch Linux. Sorry for the late response. I had switched to using Windows for the past few weeks, and just switched back to Arch Linux today. Out of habit, I ran the command to update all my packages soon after logging in. It was too late before I remembered that I needed to reproduce this bug. I ended up with the latest KDE and Plasma packages as a result. I've only been using Arch Linux for less than a day, but now, instead of KWin crashing, Plasma is crashing. I created a new bug report for it: https://bugs.kde.org/show_bug.cgi?id=405406 I also want to make a note that sleep/wake on Plasma/KDE was working fine previously, until November 2018. I had no problems whatsoever with sleep/wake. I had been exclusively using Arch Linux on my laptop for several months in 2018. My laptop went through many sleep/wake cycles with no issues. I almost never restarted Linux, or even exited/restarted Plasma. I always just put my laptop to sleep, and woke up it later. This problem started after I re-installed Arch Linux in February this year. There was a period, from November 2018 to February 2019, during which I was using Windows instead of Linux. Also, since Arch Linux uses sytemd, my guess is that the underlying command issued by Plasma for sleeping is probably `systemctl suspend` or something similar (but I haven't checked the Plasma sources on this though). Hi Vlad Zagorodniy, My laptop has an integrated Intel GPU: Intel® UHD Graphics 620. This Intel GPU is on the CPU die itself. The CPU on my laptop is the Intel Core i7 8550U. Here is the spec page for the 8550U: https://ark.intel.com/content/www/us/en/ark/products/122589/intel-core-i7-8550u-processor-8m-cache-up-to-4-00-ghz.html My laptop also has a dedicated GPU: Nvidia MX150. I have the official closed-source Nvidia driver on Linux (and not nouveau). But I don't think the Nvidia MX150 is ever active or being used. I once tried to run a game (0 A.D.) on the Nvidia GPU using `optirun` (c.f. Nvidia Optimus), but it actually ran super-slow! Even glxgears ran horribly slow on the Nvidia GPU compared to the Intel GPU. It's weird because the Nvidia GPU is a lot more powerful than the Intel GPU. I never investigated and figured out why the Nvidia GPU was super-slow on Linux. Why I stopped using Linux from Nov 2018 to Feb 2019 The story of why I had to switch to Windows for 4 months (from Nov '18 to Feb '19) is a long one, but I'll share it here, for some context. This is a bit long and rather tengetial, so please feel free to skip it. Sometime in November 2018, I was running a long-overdue update of all my packages (ie `pacman -Syu`). While some package was installing, Plasma crashed. I was in the middle of reading an article online, and Plasma suddenly crashed suddenly (with a lot of error messages), and brought me back to the shell (on Arch). My theory is that it happened because pacman (the Arch Linux package manager) was probably literally overwriting/replacing Plasma binaries, while the system was running. Also, because, my package update process was running on Konsole, I think when KDE crashed, it killed the package update process in the middle of whatever it was doing. After this happened, I think I tried to finish my update, and then rebooted my computer. But when I rebooted, the system wouldn't boot. The interrupted system update actually corrupted my Arch Linux installation. I spent several hours trying to fix it, but eventually gave up, and switched to Windows for several months (until February 2019). I had some important job interviews coming up, and I couldn't spend all my time trying to fix my Arch Linux installation. Initially, I found out that the vmlinuz image itself was broken (and non-bootable). But I fixed that / got the kernel to build properly; but after that, the next problem was that my initramfs was partially broken. The Arch Linux mkinitcpio command (https://wiki.archlinux.org/index.php/mkinitcpio) wasn't working properly, and was throwing errors while building. It would build an initramfs that lacked support for decrypting a dm-crypt partition. So I couldn't actually boot my system -- even if I could access it from an Arch Linux installation USB. Anyways, because of my job interviews, I switched to Windows for a while. Later on, in February 2019, I spent some more time trying to fix my broken Arch Linux installation, but finally decided it wasn't worth my time anymore, so I backed up my home directory, and set up everything from scratch. Ever since coming back to Arch Linux + KDE/Plasma (in February 2019), I've had this intractable sleep/wake problem.
