https://bugzilla.kernel.org/show_bug.cgi?id=65141 Bug ID: 65141 Summary: Blank screen after resume with radeon driver Product: Drivers Version: 2.5 Kernel Version: 3.7,3.11,3.12 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: tiwai@xxxxxxx Regression: No Created attachment 115031 --> https://bugzilla.kernel.org/attachment.cgi?id=115031&action=edit dmesg output with drm.debug=0x0e Reported at openSUSE bugzilla https://bugzilla.novell.com/show_bug.cgi?id=841822 The original bug report: Toshiba P775D-S7230 AMD APU A4, resume from suspend leaves screen "black". WHen I compiled and installed the proprietary AMD driver (13.8B2), it works fine. Same behavior on 12.3 as well. Reproducible: Always Steps to Reproduce: 1. Make sure AMD FOSS driver is loaded 2. Suspend (to ram or disk) 3. Resume 4. Screen is blank, machine is "resumed" Actual Results: The machine appears to be in a working state, but the screen is black Expected Results: Full function resume from suspend with video Compiling and installing the AMD proprietary driver (13.8B2) works. === The problem is seen without X, too. Reproduced on (openSUSE) 12.3 means that kernel 3.7 had already the problem. openSUSE 13.1 uses 3.11.x kernel, and the reporter tested 3.12 kernel, too. The full dmesg with drm.debug=0x0e after S4 resume is attached. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
