Bug ID: 91595 Summary: RV410 white screen after resume Product: DRI Version: unspecified Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/Radeon Assignee: dri-devel@lists.freedesktop.org Reporter: lists.jjorge@free.fr
This is a Fujitsu Amilo M1437G with X700Mobile. Suspended/resumed well with UMS with a 2009 distro, but after upgrading the system to a 2015 Mageia 5 and a KMS only driver, screen is white after suspend. If then I hibernate the system through ssh, screen is ok.
Looks like the sbios does something that KMS does not, is there a way to debug this? I join the reg dumps.
