Update – stability confirmation on 6.13.12
After extended real-world testing, I can now confirm:
Kernel 6.13.12-061312-generic is fully stable on my system.
Multiple consecutive suspend/resume cycles (10+) succeed without HDMI signal loss.
Environment:
Zorin OS 18 Core (Ubuntu 24.10-based)
Wayland session
Radeon R9 380 (Tonga XT, amdgpu)
Ryzen 5 5500
B450 Aorus Pro WIFI (BIOS F66)
HDMI 1080p60 direct connection
Behavior summary:
• 6.12.x → fully stable
• 6.13.12 → fully stable in extended testing
• 6.14+ → resume instability begins
• 6.17.0-14 → reproducible HDMI black screen after 1–2 suspend cycles
This narrows the regression window between 6.13 and 6.14.
Symptoms in broken kernels:
System resumes (fans/LEDs active)
Monitor reports no signal / out of range
dmesg shows EDID-related errors on HDMI-A-1 during resume
Requires hard reboot to restore display
Given that 6.13.12 is stable and 6.14+ is not, this may be related to
display reinitialization, EDID re-probing, or DC changes introduced
after 6.13.
I'm willing to:
Test 6.14.x point releases
Collect comparative dmesg logs (6.13 vs 6.17)
Help narrow down specific commits if needed
My goal is to return to the latest stable kernel once the regression is
resolved.

Title:
amdgpu (R9 380) fails to resume from suspend (deep sleep) – black
screen, requires hard reboot
Status in linux package in Ubuntu:
New
Bug description:
AMDGPU suspend → display black / no video after resume on Radeon R9
380 (No EDID read)
Summary:
After system suspend from Zorin OS 18 (Ubuntu 24.10 base, kernel 6.17.0-14), the system sometimes resumes but the display remains black (no signal). System continues running (fans/LEDs active), but monitor shows no output. Only hard reboot restores video.
Steps to reproduce:
Boot Zorin OS 18 (Ubuntu 24.10 kernel 6.17).
Suspend system (e.g., via GNOME "Suspend").
Wait short period.
Attempt to resume (mouse/keyboard).
System wakes but display either shows garbled video or no output.
Observed behavior:
System appears not crashed (fans/LEDs/keyboard continue).
Screen stays black or displays remnants but no usable video.
Sometimes resume works, sometimes fails.
Relevant log excerpt:
amdgpu 0000:01:00.0: [drm] *ERROR* No EDID read.
Hardware:
Motherboard: Gigabyte B450 AORUS PRO WIFI
CPU: AMD Ryzen 5 5500
GPU: AMD Radeon R9 380 Series (Tonga, amdgpu driver)
Software environment:
Zorin OS 18 Core (Ubuntu 24.10 base)
kernel: 6.17.0-14-generic
X11 session
Workaround currently applied:
Suspend disabled. System remains stable without suspend.
Note: Bug appears related to video resume rather than system freeze;
display subsystem (EDID handshake) may fail after suspend.
Additional info:
Similar reports of amdgpu black screen / suspend issues exist (e.g., Launchpad #2141216) and community discussions on black screen resume after suspend for AMD GPUs.

Thermal and power monitoring issues: CPU overheats and fan control
broken/strange
Status in linux package in Ubuntu:
Confirmed
Bug description:
On my ThinkPad P72 with i7-8850H CPU (Coffee Lake) the thermal setup is horrible: it runs very hot (you can feel it on the keyboard as well as the air exhausted by the fan) even when idle, the fan speeds up and gets silent after a a short time for no obvious load reasons when the system is idle.
(Definition of idle: quite a few browser tabs open in firefox and chrome sitting in the background untouched since a longish time, no interaction by the user with the machine)
The reported CPU temperature rises to an average of 60°C during idle with sporadic peaks well over 80°C (e.g. 95°C) for a single CPU.
With slight work (browsing the web) temperature rises with more often temperature peaks rising high - expected due to the higher work load. But still far too much for the little work load for such a high end machine.
Chances are high that after a short while the CPU frequency gets hard
locked at 800 MHz with no way I could figure out to get out of that
apart from rebooting.
A cross check with Windows 10 (dual boot) showed a much better thermal
behavior there. Temperatures stayed lower and under high load the fan
is running on a moderate level with the CPUs averaging at about 3 GHz.
Actually it showed the behavior that I expected for Linux...
During my search for causes and ways to fix it I tried so far:
- disabling hardware P-states or even the pstate driver - no improvement (actually I felt it was even slightly worse)
- switching from laptop-mode-tools to tlp (no change)
- activating everything from powertop (no change)
- running powerstat was very interesting:

Bug description:
After updating Kubuntu via Update-Manager, my inbuilt wireless onboard
module "Realtek RTL8821CE, PCIe 10ec:c821" no longer worked. This
concerns update of older kernel version 6.14.x to 6.17.x HWE. Under
HWE 6.17.x the wireless network no longer worked on my laptop. After
fallback on the older kernel 6.14 I got immediate internet access
again. So please consider supporting the "Realtek RTL8821CE"-driver
under the next kernel versions again.

Bug description:
Dear Canonical Developers,
Wayland is effectively in an alpha state and contains several critical
bugs. Why are you forcing this broken and unusable software onto
Ubuntu users? Why have you blocked the use of X11? What is the purpose
of this?
Dear Canonical Developers,
I am asking you to either completely get rid of this trash called Wayland or, as a second option, start developing and fixing the critical bugs in this software. Canonical has enough financial resources to fund its proper development.
Dear Developers,
Wayland is a nightmare for those developing screen recording software. You are putting too much strain on these developers. Please fix these critical issues. Described below is just one of many unsolvable problems that screen recorder developers are currently facing.
**************
Global hotkeys not working in OBS Studio (Flatpak) on Kubuntu 25.10
*********
I am experiencing an issue with global hotkeys in OBS Studio.
Environment:
OS: Kubuntu 25.10
Version: OBS Studio (Flatpak)
Display Server: Wayland
The Problem: Hotkeys for "Pause" and "Resume" recording only work when
the OBS Studio window is focused in the foreground. If I am recording
another application and that application has focus, the hotkeys do not
work at all.
Questions: Is this a Wayland-related issue? I know that Kubuntu/Ubuntu
now enforces Wayland by default. While X11 is installed, there is no
option to select it at the login screen (SDDM).
I haven't found any working guide on how to resolve this or how to
force an X11 session.
How can I get global hotkeys to work in the background on Wayland, or
how can I switch back to X11?

[Bug 2142905] Re: Bug report. Global hotkeys not working in OBS Studio (Flatpak) on Kubuntu 25.10
Note: The root of this bug does not lie within the isolated Flatpak
environment. I have installed the APT version of OBS Studio, and the
issue is identical—global hotkeys still do not work. I believe the core
problem is the overall flawed concept of Wayland. However, everything is
fixable.
I consider it extremely irresponsible of Canonical's management to
forcibly impose Wayland while sophisticatedly blocking X11, all without
contributing financially to Wayland's development to resolve its
critical flaws. Currently, there isn't a single screen recording
application that functions correctly on Wayland.
I sincerely urge Canonical's management to begin contributing to
Wayland's development, either through funding or by assigning dedicated
developers. Alternatively, X11 should be unblocked by default.
Unfortunately, I have been unable to find any documentation or guide on
how to re-enable X.org in this version.

Dear Developers,
Wayland is a nightmare for those developing screen recording software. You are putting too much strain on these developers. Please fix these critical issues. Described below is just one of many unsolvable problems that screen recorder developers are currently facing.
**************
Global hotkeys not working in OBS Studio (Flatpak) on Kubuntu 25.10
*********
I am experiencing an issue with global hotkeys in OBS Studio.
Environment:
OS: Kubuntu 25.10
Version: OBS Studio (Flatpak)
Display Server: Wayland
The Problem: Hotkeys for "Pause" and "Resume" recording only work when
the OBS Studio window is focused in the foreground. If I am recording
another application and that application has focus, the hotkeys do not
work at all.
Questions: Is this a Wayland-related issue? I know that Kubuntu/Ubuntu
now enforces Wayland by default. While X11 is installed, there is no
option to select it at the login screen (SDDM).
I haven't found any working guide on how to resolve this or how to
force an X11 session.
How can I get global hotkeys to work in the background on Wayland, or
how can I switch back to X11?

[Bug 2142443] Re: [resolute] Installed an Nvidia driver and now booting to a frozen black screen
"Won't Fix" for Linux because that would mean we ship a kernel without
Nova modules. Instead, the Nvidia driver packaging will just disable
Nova.
