我正在使用具有 4k 显示屏和 ubuntu 作为操作系统的戴尔 XPS 15 9550。我需要使用 Matlab,但我(一如既往)有一个 HighDPI 问题。目前我正在使用 r2017a 版本的 Matlab。
为了解决这个问题,我尝试使用一个小脚本来避免这个问题:
脚本.sh
#!/bin/sh
#set scaling to x1.0 to remove the zoom used in HDPI screens
gsettings set org.gnome.desktop.interface scaling-factor 1
#Used in ubuntu machines
gsettings set com.ubuntu.user-interface scale-factor "{'HDMI1': 8, 'eDP1': 8}"
#applying full HD resolution
xrandr -s 1920x1080
# call your program
/usr/local/MATLAB/R2017a/bin/matlab
#wait for the process to terminate
wait
#now coming back to the original screen resolution and scaling
# set scaling to x2.0
gsettings set org.gnome.desktop.interface scaling-factor 2
#same as before
gsettings set com.ubuntu.user-interface scale-factor "{'HDMI1': 8, 'eDP1': 16}"
#back to original resolution
xrandr -s 3840x2160
当我启动它时,我从控制台收到此错误:
“在可用模式中找不到尺寸 1920x1080”
所以我做了:
cvt 1920 1080 60
输出:
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
在那之后:
xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
最后
xrandr --addmode eDP-1-1 1920x1080
我使用 xrandr -q 找到了 eDP-1-1。这里的输出
Screen 0: minimum 8 x 8, current 3840 x 2160, maximum 16384 x 16384

所以我认为我已经做对了所有事情,但是脚本仍然不起作用,控制台仍然给我同样的错误。
我做错了什么?
