Bug ID: 88063
Summary: Radeon driver with dual monitor does not wake properly
from sleep
Product: xorg
Version: 7.5 (2009.10)
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/Radeon
Assignee: [email protected]

I have a dual monitor configuration with Fedora 20 and now Fedora 21 setup with
the following card:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Caicos XTX [Radeon HD 8490 / R5 235X OEM]
One monitor is using DVI, the other monitor is using a display port -> DVI
connector. This setup works great for day to day usage, with no real issues.
When the monitors go to sleep (when I leave for an extended period of time) the
monitors don't wake up properly.
One monitor wakes up 100% fine, the other monitor wakes up but has a garbled
display. My mouse will then only traverse the working monitor, as the second
has dropped from the configuration. The fix is just to log out of KDE and log
back in.
I'm running the following version of the radeon driver.
[959996.504] (II) LoadModule: "radeon"
[959996.504] (II) Loading /usr/lib64/xorg/modules/drivers/radeon_drv.so
[959996.505] (II) Module radeon: vendor="X.Org Foundation"
[959996.505] compiled for 1.16.1, module version = 7.5.0
[959996.505] Module class: X.Org Video Driver
[959996.505] ABI class: X.Org Video Driver, version 18.0
Issue has persisted from Fedora 20 to Fedora 21. The two solutions I've found
to this problem are:
1) Logout/login again
2) Run the fglrx driver instead
