ReillyBrogan Latest update meaning our latest sync, and I'm working under Wayland for now. Once I'm done for the day I'll close out my work and switch to X11 to see if the monitor reports a different refresh rate/what the xrandr settings report, etc. and report back.
Plasma 6 Megathread
Bhibb I was wrong, we actually do have a tool to parse the monitor EDID and it should already be installed since you're on Plasma. You can run the following to see the exact resolutions and frame rates that your monitor supports:
ls /sys/class/drm
# This will show you the GPUs detected and the ports they have. The following command will depend on which GPU you're checking and which port
cat /sys/class/drm/card0-DP-1 | di-edid-decodeReillyBrogan Looks like 60 is all I've got, so I must have mis-remembered!
cat /sys/class/drm/card0-DP-1/edid | di-edid-decode

[deleted] I can't reproduce that, is it still an issue?
- Edited
Bhibb I owned this monitor and I'm sure it had 100 Hz. When I google for it the specs also say 100 Hz. If you look at Detailed Timing Descriptors. DTD 2: Has 99.98 Hz.
kaktuspalme Sebastian Thank you both for jogging my memory and for the link to rollback.
I've tried to rollback to 3/30/2024's update, but even after a reboot my external monitor still shows 60 hz in Wayland and X11. The monitor is working at 60hz and 50hz, but it won't show me 100hz (or 99.98hz). I tried rolling back to other upgrades, and with reboots the refresh rate was still the same.
I've noticed a new issue where I cannot "logout" of my Plasma 6 session (X11 or Wayland) and if I want to switch between them I need to "Switch Users." When I click the logout button it kills my apps, but does not actually logout.
My system is working, but these two issues are the major ones now:
- USB C to Display Port monitor used to show 99.98hz, now shows only 50 and 60hz.
- I cannot log out of a Plasma 6 session (X11 or Wayland).
Might be a kernel bug. You should try booting into the previous kernel
ReillyBrogan Thanks for suggesting this. I just rebooted into the previous kernel on my machine but the same issues persist: I cannot select 100hz on my monitor and I cannot logout of my session.
ReillyBrogan So I realized that while I was gone on a trip for a week, that I had let someone else use my desk and monitor. Somehow they had set my Display port to 1.1 instead of 1.2, and once I set this back to 1.2 it miraculously solved both my issues of the missing 100hz (pretty obvious) and I know have the ability to logout as expected (not sure why the monitor would have anything to do with this).
Somehow it's all working now. Thanks for troubleshooting with me.
[deleted]
ReillyBrogan The issue is still present. I have done a bit more reading and it seems that it is connected to the presence of the tray icon. When the icon is disabled and I change download preferences then qBittorrent crashes, if I enable it then I can change download preferences and it won't crash. GitHub qBittorrent Issue #20604 (Closed), GitHub qBittorrent Issue #20627 (Open).
kaktuspalme
No, it's also present on X11 (I'm on X11).
I reported it on bugs.kde, there's a whole thread on this issue.
rincor Yes I've seen the bug report. I don't know wether you are using Jetbrains Tools as well. But in case you have that problem also with those tools, I deactivated the New UI. So far I didn't have the bug again, but not enough time yet to say it's not happening anymore.
kaktuspalme
I use the classic UI, but the bug is still there unfortunately.
Hopefully it will resolved soon, though it was first reported in Dec.

just installed solus plasma 6
but i cant mount my luks encrypted external usb drive. which is a problem as it contains ALL my stuff.
the disks and devices applet says "you are not authorized to mount this drive"
and dolphin says " an error occured while accessing [drive id] the system responded: the object does not exist at path "/" "
tried both x and wayland, and 2 different drives, both produce the same error. im guessing its something trivial, but ive never encountered this before
HELP
edit: mounts no problem on my solus gnome laptop
edit 2: can mount it if unlocking the drive in kde partition manager first
I have encountert such a problem in past. Haven't digged into it. But if I remember right it does not occur with identical username.
You have a different user name on your Solus GNOME Laptop?
Sebastian nope, same username
- Edited
seems related to kde frameworks 6.1 https://forum.manjaro.org/t/kde-plasma-dolphin-wont-mount-external-ssd-luks-partition-anymore-object-does-not-exist-at-path/160015
https://bugs.kde.org/show_bug.cgi?id=485507
@ReillyBrogan anything you can do ? (afaik you're the kde guy)
Lucien_Lachance I literally just had this problem starting this week. My workaround was to install gnome-disk-utility and decrypt the drive through the GUI there. Once decrypted, it mounts for me (my 14TB backup drive is mounted this way).
Bhibb yes that seems to work nicely as a workaround. just a bit inconvenient.

on an unrelated matter, anyone got emojis in plasma notifications ? im just getting squares
