    Hello,
    I have installed Deepin 15.11 and run some updates and reboot. Suddenly the brightness went dim. I tried to increase brightness with key and it set to max but still the screen was dim. The only fix I could find is [color=var(--newCommunityTheme-linkText)]here such putting the system into suspense and login back again. As in the mentioned link, the OP posted the issue using 15.7 but the issue still persists on 15.11. Seems like an unnoticed bug ?

    same as this my inxi report as below
    1. Graphics: Card: Advanced Micro Devices [AMD/ATI] Device 15dd bus-ID: 03:00.0
    2. Display Server: X.Org 1.19.6 drivers: modesetting,ati (unloaded: fbdev,vesa,radeon,amdgpu)
    3. Resolution: [email protected]
    4. GLX Renderer: AMD RAVEN (DRM 3.23.0, 4.15.0-30deepin-generic, LLVM 6.0.0)
    5. GLX Version: 3.1 Mesa 18.1.9 Direct Rendering: Yes
    Copy the Code
    so it seems my system is not using AMDGPU driver, how can I force it use the correct diver ?  there is a graphics driver manager and it does show as in this screenshot.

    may be this is the reason for this brightness bug ?

    thank you for the help
