Linux – the only operating system that supports horizontal, vertical and diagonal screens
Linux is the only operating system that supports diagonal screen rotation, which is very beneficial for programmers. Until now, you only had 2 display modes: landscape (horizontal rotation) or portrait (vertical rotation), limited to the horizontal or width of the screen with a perpendicular axis (rotated 90 degrees), and the xrandr tool in Linux Allows display content to be rotated to any angle.
Developer xssfox has applied xrandr and found that the sweet spot when rotating the 21:9 screen in use is the 22 degree angle. Accordingly, at this angle, it will bring the experience of using a screen with a display space equivalent to a 32:9 ratio on an ultra-wide screen. Of course, if you already own a 32:9 screen, rotate it 22 degrees with Linux xrandr and it will be even wider. For screens with uncommon ratios, you can use xssfox’s javascript tool to create the xrandr script after entering input data. One of the examples that can make good use of xrandr is the LG DualUp screen, 16:18 ratio is almost square, then the optimal rotation angle is about 45 degrees.
