我刚买了一台新的笔记本电脑 hp spectre x360,有两个令人恼火的问题:
1- 声音不起作用,我已尝试过这页面没有成功。
终端输出

2-图标非常小,通过放大字体可以部分解决问题,但是有些图标仍然很小。
答案1
HP 支持论坛上的某个人找到了解决方案因为缺乏声音。您应该确保先备份您的计算机,因为它确实涉及修改 GRUB 的配置。步骤如下:
通过执行以下操作来编辑 grub 配置:
'
sudo vim /etc/default/grub
'编辑此行:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash'"
到:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012'"
然后运行:
'
sudo update-grub
'重启两次。
之后您可能需要更改音量或静音设置。
