Message-ID: <bug-102351-2300@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=102351
Bug ID: 102351
Summary: Radeon R9 270: Flickering Screen (Dual Monitor setup)
Product: Drivers
Version: 2.5
Kernel Version: Linux 4.2RC5
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: beta992@gmail.com

Samsung Monitor setup
Hardware Setup:
- ASUS P8H67-M Pro B3
- Club 3D Radeon R9 270 royalQueen:
*DP => works without any issues (DELL U2312HM)
*DVI => flickering, on/off (Samsung 2253LW)
Booting with the following parameters reduces the flickering, but still it
keeps happening: radeon.audio=0 radeon.bapm=1 radeon.disp_priority=2
radeon.hw_i2c=1 radeon.msi=1 radeon.mst=1 radeon.tv=0
In Windows 8.1 this also happens, but less frequent then in Linux.
The Samsung monitor seems to be working fine (pretty old), but I think this
could be a DVI issue (has only VGA/DVI-output), but can't test on HDMI.
Thanks and please let me know if more debug info is needed.
