Bug ID: 108520
Summary: MST DisplayPort HiDPI screen flicker
Product: xorg
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau
Assignee: [email protected]
Reporter: [email protected]
QA Contact: [email protected]
HiDPI MST monitor connected via DisplayPort has bad screen flicker (one to
three high speed flickers every 20 seconds or so).
Version of X: 1.20
Nouveau: 1.0.15-3
Kernel: 4.18.16-arch1-1-ARCH
Curiously, the flicker only happens on my Optimus laptop with Hybrid Graphics
disabled (Intel off, Nouveau on). The flicker disappears if Hybrid Graphics is
enabled (Both Intel and Nouveau cards on).
Can't find anything relevant in dmesg, journal etc., but let me know which logs
will be useful and I can upload them.
