Just to let you know that the current release candidate 2.0~rc1 sorts
out problems with Hi-DPI screens. Now everything is of readable size.
Before one needed a magnifying glass just to use the system.
I assume this has been fixed upstream in Debain, but it is of great help
because TAILS has no option to lower the resolution on the display, and
until now most things - icons, texts, browser, keypassx, etc. - were
unusably small to read.
