Reproducable 100% of time. I quit Sagara Family from main menu and monitor loses signal instead of showing desktop. I can restore signal by lowering resolution with ARandR and then putting 1920x1080 back. journalctl shows this: com.deepin.daemon.Display[6672]: manager.go:575: [updateMonitor] Set mode '115' failed: Invalid output mode: 115 ------------------ Graphics: Card: Advanced Micro Devices [AMD/ATI] Tonga PRO [Radeon R9 285/380] Display Server: x11 (X.Org 1.19.3 ) driver: amdgpu Resolution: 1920x1080@60.00hz, 1920x1080@60.00hz OpenGL: renderer: AMD Radeon R9 200 Series (AMD TONGA / DRM 3.15.0 / 4.12.13-1-ARCH, LLVM 5.0.0) version: 4.5 Mesa 17.2.1 wine-staging 2.17 ------------------ Arch Linux stock kernel does above mentioned behaviour. Linux 4.12.0-1-amd-staging loses signal from second monitor instead of first one as soon as game is launched, and signal can be restored the same way.
Please attach your xorg log, dmesg output, and `xrandr --verbose` output. I'm not familiar with the game off hand, but it sounds like the game may not be randr 1.2+ aware.
Using AMD Radeon R9 200 Series (AMD TONGA / DRM 3.20.0 / 4.12.0-1-amd-staging, LLVM 5.0.0), xorg 1.19.5 Sagara Family loses signal from Asus VE247 (2nd monitor DVI-D-1) on starting game in fullscreen.
