内核错误: systemd-backlight@backlight:acpi_video0.service
提问于 2021-03-16 12:06:00
我总是在引导时收到这个错误。有什么重要的事情吗?如果是的话，怎么解决呢？我知道这和我的AMD GPU有关。下面是我的设置：
- Cpu: AMD A9-9420 RADEON R5，5个计算核心2C+3G，2586 MHz。
- GPU: ATI Stoney，AMD ATI Radeon R5 M230 / R7 M260DX / Radeon 520 Mobile
- 4GB RAM，250 4GB
- 操作系统:5.9.16-1-1-Manjaro #1 SMP抢占Mon 12月21日22:00:46 UTC 2020 x86_64 GNU/Linux
下面是上一次引导时的内核日志：

编辑文件/etc/default/grub并将以下参数添加到GRUB_CMDLINE_LINUX:
中
$ sudo nano /etc/default/grub
GRUB_CMDLINE_LINUX="acpi_osi=Linux acpi_backlight=vendor"以后不要忘记运行update-grub。
为我解决了这个问题！我把它放在ATI/AMD上，一个相当老的gpu。我也想提到这一点，没有破坏调整屏幕亮度的能力。
，祝你的htop值低，胡子长！
