So I tried these commands: xrandr --newmode "1440x900" 106.5 1440 1520 1672 1904 900 903 909 934
xrandr --addmode default 1440x900 xrandr --fb 1440x900 liveuser@localhost-live ~]$ xrandr --output default --mode 1440x900 xrandr: Failed to get size of gamma for output default xrandr: Configure crtc 0 failed
How do I get xrandr or something else to do what I want, i.e. change my resolution to 1440x900 when using the live DVD.. It is what I have on Centos 7. That is where I got the numbers to use.
