如何防止X11爲tty7設置opost？

Question

好日子

我的Ubuntu 16.04.1機的i915顯卡有TTY2以下設置：

速度38400個波特; line = 0; -brkint -imaxbel iutf8

而對於TTY7（用於X11的終端是）

速度38400波特的設置; line = 0; min = 1;時間= 0; IGNBRK -brkint -icrnl -imaxbel -opost -onlcr將 -isig -icanon -iexten -echo -echoe -echok -echoctl -echoke

大概X11/lightdm xinit的/ startx的期間產生用於TTY7那些設置。如何更改由X11/lightdm for tty生成的終端設置？

乾杯，

如果X上運行TTY7，你不會使用它的外殼登錄。但是你可以改變終端屬性（不管它是否有用取決於你對它的用處）。

假設你有權限，例如，運行在根：

stty opost </dev/tty7 

即，重定向打開終端上的有效的文件描述符。您可能會看到類似這樣的內容：

$ sudo su - 
[sudo] password for whoever: 
# stty -a </dev/tty7
