1、查看当前支持的所有分辨率
xrandr命令查看,或者在 系统设置-->显示-->分辨率选项里就可以看到当前可选择设置的分辨率,如1920x1080在新加之前当前系统并未支持,如下为新增了920x1080后的查看情况:
krj-16-4@ubuntu:~$ xrandr
Screen 0: minimum 1 x 1, current 1920 x 1080, maximum 8192 x 8192
Virtual1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
800x600 60.00 + 60.32
2560x1600 59.99
1920x1440 60.00
1856x1392 60.00
1792x1344 60.00
1920x1200 59.88
1600x1200 60.00
1680x1050 59.95
1400x1050 59.98
1280x1024 60.02
1440x900 59.89
1280x960 60.00
1360x768 60.02
1280x800 59.81
1152x864 75.00
1280x768 59.87
1024x768 60.00
640x480 59.94
1920x1080 59.96*
Virtual2 disconnected (normal left inverted right x axis y axis)
Virtual3 disconnected (normal left inverted right x axis y axis)
Virtual4 disconnected (normal left inverted right x axis y axis)
Virtual5 disconnected (normal left inverted right x axis y axis)
Virtual6 disconnected (normal left inverted right x axis y axis)
Virtual7 disconnected (normal left inverted right x axis y axis)
Virtual8 disconnected (normal left inverted right x axis y axis)
2、查看当前所有的montior:
krj-16-4@ubuntu:~$ xrandr --listmonitors
Monitors: 1
0: +*Virtual1 1920/508x1080/286+0+0 Virtual1
3、获取要添加的分辨率信息,通过cvt命令:
krj-16-4@ubuntu:~$ cvt 1920 1080
# 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
4、向 /ect/profile配置文件中增加分辨率配置信息:
向 /ect/profile配置文件末尾,新增如下两行信息,使用source /etc/profile使新增配置生效,或者重启生效。
krj-16-4@ubuntu:~$ tail /etc/profile -n 2
xrandr --newmode "1920x1080" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
xrandr --addmode Virtual1 "1920x1080"
5、配置新增的分辨率选项:
增加完配置后,在系统设置-->显示-->分辨率中就可以选择1920x1080的分辨率了。
