Hi,

Parveena Mukherjee:
> So far, up to Tails 2.4, I set the resolution for my second display (which is

> xrandr --output HDMI1 --mode 1680x1050
> After upgrading to Tails 2.6, the "1680x1050" resolution does not show in the
> "xrandr" command, and the screen Cannot be set above 1024x768 resolution.
> The following does not help:
> ~$ xrandr --newmode "1680x1050_59.90" 146.89 1680 1784 1968 2256 1050 1051
