Bug ID: 471852
Summary: Desktop freezes on every login of Plasma 6 Wayland,
(KDE Neon) using Nouveau Nvidia driver
Classification: KDE Neon
Product: neon
Version: unspecified
Platform: Neon
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: Packages Unstable Edition
Assignee: neon-b...@kde.org
Reporter: publiclyvisibleem...@gmail.com
CC: j...@jriddell.org, neon-b...@kde.org, sit...@kde.org
Target Milestone: ---
SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See

STEPS TO REPRODUCE
1. Only be using Nouveau Nvidia driver, (i.e. as after a fresh install of KDE
Neon Unstable)
2. On login screen, change from Plasma (X11) to Plasma (Wayland)
3. Login
OBSERVED RESULT
1) There's a momentary square of distorted colors in the upper left before the
desktop renders, after which the screen goes black.
2) The desktop is then rendered, looks fine, but almost immediately the mouse
pointer freezes and then the entire desktop does, so that it's entirely
unusable, with different distorted parts of the screen showing over the desktop
with each login.
3) After force-shutting down the entire laptop, and restarting, (note: before
the KDE Neon logo comes up, there was mention of some failure of the nouveau
driver, (after two other ACPI errors) - I believe this was one of my other bug
reports) if you leave the login screen set to Plasma (Wayland) you'll see a
repeat of the above every time. If you change to Plasma (X11) you will have a
fully functioning desktop.
4) Note: after installing the (535) proprietary Nvidia drivers, (via sudo
ubuntu-drivers install) Plasma (Wayland) seems to work fine, so it's only an
issue with the nouveau drivers.
EXPECTED RESULT
A fully functioning desktop.
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma: KDE Neon Unstable, (just installed fresh from Live iso today
- 2023-07-01). Note: did do a pkcon refresh and sudo pkcon update, which I
think was after the above kept happening, and am now running the 535
proprietary Nvidia drivers, so can no longer replicate the issue, so the
versions in About System might be newer than those that were in place when the
above was happening. That being said, About System reads:
- KDE Plasma Version: 5.27.80
- KDE Frameworks Version: 5.240.0
- Qt Version: 6.5.1
- Kernel Version: 5.19.0-46-generic (64-bit)
