我的显示器出现间歇性问题。从休眠模式恢复后，显示器会调整大小。
这是我的图形硬件：
me@computer:~$ /usr/bin/inxi -G
Graphics: Card: Advanced Micro Devices [AMD/ATI] Ellesmere [Radeon RX 470/480]
Display Server: x11 (X.Org 1.19.6 ) drivers: ati,amdgpu (unloaded: modesetting,fbdev,vesa,radeon)

休眠之前（正常运行，1360x768）：
me@computer:~$ xrandr

休眠后（压缩为 1280x720）：
me@computer:~$ xrandr

640x480 60.02

DVI-D-0 disconnected (normal left inverted right x axis y axis)
分辨率在重启后会自动更正。我更希望在不重启的情况下停止此问题或更正分辨率。
在系统日志中，有一堆与系统恢复时间一致的消息，其中 kscreen.xrandr 似乎正在尝试调用 1360x768，失败，然后调用 1280x720。
我将不胜感激大家提供的任何帮助。也许只是驱动程序的一个错误？我正在使用这个 ppa：https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers
