Public bug reported:
Problem Description:
The desktop session abruptly crashes and forces me back to the GDM/login
screen. There is no rigid pattern, but it consistently triggers when
multitasking with resource-heavy or graphical applications under Linux kernel
7.0.0-30-generic.
It frequently occurs when opening:
- Zoom + VS Code + Terminal simultaneously.
- Zoom + VS Code, followed by launching Counter-Strike 2 (CS2).
Hardware Environment (Current Desktop):
32 GB RAM
AMD RYZEN 5 7640hs
1 TB SSD
AMD RADEON graphics
Additional Hardware Verification:
Note for developers: I have verified that this exact same issue also occurs
under identical conditions on my Acer Swift 3 laptop, which runs the following
hardware:
- CPU: AMD Ryzen 7 5000 Series
- GPU: AMD Radeon Graphics
- RAM: 16 GB
Steps to Reproduce:
1. Boot into the desktop session using kernel 7.0.0-30.
2. Launch combinations of Zoom, VS Code, and a terminal window, or launch Zoom,
VS Code, and CS2.
3. The display frozen briefly or immediately crashes, dropping the user session
straight back to the login screen.
Expected Behavior:
The desktop environment should manage the window composition, application load,
and graphical rendering without terminating the user session.
Actual Behavior:
The graphical display server crashes instantly back to the login screen, losing
all unsaved work.
