Bug ID: 99311
Summary: [regression,radeonsi] Updating to 1edc53a66b breaks
SDDM (white screen on launch)
Product: Mesa
Version: git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Keywords: regression
Severity: major
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: dri-devel at lists.freedesktop.org
Reporter: kai at dev.carbon-project.org
QA Contact: dri-devel at lists.freedesktop.org
Somewhere between c93efb0a4f and 1edc53a66b a regression was introduced,
causing SDDM launching into a pure white screen instead of the login screen.
There's nothing logged to either /var/log/Xorg.0.log or /var/log/sddm.log and
dmesg is also clear. Downgrading to c93efb0a4f lets me login again.
I have not bisected yet, but maybe this information is already enough to find
the cause. For the full stack affected by this regression, please see below.
