我使用戴尔XPS 15 9550与4k显示器和Ubuntu作为操作系统。 我需要使用Matlab,但我有(一如既往)HighDPI问题。目前我使用的是Matlab的r2017a版本。xrandr尺寸1920x1080未找到可用模式ubuntu
为了解决这个问题,我试图用一个小脚本,以避免该问题:当我启动它,我收到此错误控制台
Myscript.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
:
:所以我做了“大小1920×1080没有可用的模式找到了”
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
之后:
xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
,并使用xrandr -q终于
xrandr --addmode eDP-1-1 1920x1080
我发现EDP-1-1。这里输出

所以我觉得我已经做了所有正确的事情,但还是剧本不能正常工作和控制台仍给我同样的错误。
我做错了什么?
