我检查了Fedora 21安装所在的Gnome 3.14.2,似乎无法设置所需的值:
[btegge@za21 ~]$ gsettings set org.gnome.desktop.interface scaling-factor 1.2
invalid character in number:
1.2
^
[btegge@za21 ~]$ gsettings set org.gnome.desktop.interface scaling-factor 1,2
expected end of input:
1,2
^
我的假设:
如果您切换到Wayland显示服务器,则可以执行以下操作:https : //www.omgubuntu.co.uk/2017/09/enable-fractional-scaling-gnome-linux
否则,您唯一的选择似乎是使用新版本的GNOME升级到发行版。此功能在Ubuntu 19.04中可用:https : //www.omgubuntu.co.uk/2019/06/enable-fractional-scaling-ubuntu-19-04
