SUMMARY After update to 5.25 (not sure about sub-version, looking at my deletion of .config it is few days after 5.25.1) startup has been very slow. After login, it used to be pretty much immediate to have usable desktop; now i get my background without any panel for 5-10 seconds, then the screen goes black, then desktop appear. Also my Vaults, KDE Connect and maybe few more will NOT load properly, they are running but see no vaults/device connected, i need to log out and log back in; then the log in will be immediate as normal, and all the widget works as expected. So pretty much for a few weeks I log in, wait ~30seconds to log in, log out, and log in again. I tried removing the ".local/share/plasma*" to start from a clean startup, but the issue persist. There seems to be no error reported in jounalctl, so i have no idea how to start debugging this. STEPS TO REPRODUCE 1. update to 5.25 2. log in OBSERVED RESULT very slow to desktop, broken widget EXPECTED RESULT immediate to working desktop SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.25.4 KDE Frameworks Version: 5.96.0 Qt Version: 5.15.5 Kernel Version: 5.18.16-arch1-1 (64-bit) Graphics Platform: X11 Processors: 12 × AMD Ryzen 5 3600 6-Core Processor Memory: 15.5 GiB of RAM Graphics Processor: AMD Radeon RX 5700 XT Manufacturer: Gigabyte Technology Co., Ltd.

How many screens are you using? Are there any crashes during login? You can check using `coredumpctl --reverse`; the items at the top will be the most recent crashes. If you find any, can you paste the output of that command that shows the new crashes that happened during login?
(In reply to Nate Graham from comment #1) > How many screens are you using? AH, ok, if we talk screen, then something weird also start to happen. First of all, i am using xorg, with 2 screen, primary is 1440p 75Hz and the other 1080p 60Hz The 1440p is slower to start up, but lately seems to be "slower". Switching to a virtual terminal with ctrl+alt+Fx seems immediate and works correctly. BUT, this also happen when only the 1440p monitor is on. > Are there any crashes during login?

If you > find any, can you paste the output of that command that shows the new > crashes that happened during login? no crashed according to `coredumpctl --reverse`, just a few of unrelated program i use daily (vscode, clion, teams) I logged in into a test user, that should be clean. Same problem, login from sddm started at 23:28:37, i got dolpin opened almost immediately full screen (so it IS able to restore session, at least partially correct, it is trying to open my main user home.. but sure was not left open on that), panels does not appear until 23:29:30, then the system is fully usable. Then i log out at 23:29:53, at 23:30:02 there is a coredump, and actually what i notice is instead of monitor going black for a moment after log out, it took a few seconds longer. At 23:30:33 we can see the second login, and in less than a few seconds I am on the fully functional desktop. Notice, this was a default user, my main user does NOT use session restore, so we can exclude some rogue issue there. See boot.txt

Thanks for the info. Can you try the Wayland session and see if it's broken there too? In general, multi-monitor mixed DPI mixed refresh rate use cases work better there too.
wayland even worse, it has completerly froze my system, not even virtual console or the capslock light. Seems like the magic REISUB worked tho, so the kernel was alive Also note those test have been made with only ONE monitor on (but the other still connected, maybe i should try disconnect it?) I just remember at certain point i switched from proprietary AMDGPU to the open Radeonsi, im now gonna try switch back and see it that was the source of the issue!

my bad, i was playing a bit around with vulkan driver (radeon vs amdvlk) but is all back to initial state and the issue is still there

I upgraded to linux kernel 5.19.10 and so far seems everything is fine. As side note, I find very interesting how a kernel issue with the graphics driver, break unrelated functionality, but also that those broken application does not seems to report anything.
ok, the kernel problem seems gone, the system mostly works, BUT i still sporadically get the issue. But at least now there is a bit more info: Oct 01 12:39:33 primero xdg-desktop-portal-kde[737]: This application failed to start because no Qt platform plugin could be initialized.
