Terminal emulators having weird behaviors
« on: June 25, 2018, 03:15:17 AM »
Hi all.
I have encountered some weird behaviors with terminal emulators on TC64, especially aterm.

behavior 1:
 When you are typing variations on previous commands,
 you would press the arrow key "UP" to call the history,
 then hold down "LEFT" key until the cursor reaches the proper position and do your modifications.
 In my case, when I hold down "UP", the terminal recalls the previous command and stop recalling.
 When I hold down "LEFT", the cursor move one character to the left and stop moving.
 This problem also present in rxvt, gnome-terminal, vte and perhaps more.
 This behavior only appears in terminal emulator, the TTYs are fine.

behavior 2:
 aterm freeze without apparent signs.
 It just stop responding.
 I can drag it around with mouse but it won't scroll up and down.
 I can click the X button and close the window without any trouble.
 When I open another terminal, everything is "normal" again. (behavior 1 still present)

behavior 1: ...
It sounds like  auto-repeat  is turned off, at least for X. Maybe see if using  xset  to turn on  auto-repeat  helps:
Code: [Select]
xset r on

behavior 2: ...
Did you by any chance hit the  Esc  key? Does hitting  Alt-Tab  a couple of times bring it back to normal?

I don't think it's "Esc" related as I hit it pusposely but nothing happens.
The freeze occurs randomly.  :P
When it does, only the window manager bar (openbox) is responsive.

behavior 2:
If you press CTRL+S the terminal stops outputting text and appears to be frozen while it actually isn't.Pressing CTRL+Q would bring it back to normal.
Download a copy and keep it handy: Core book ;)

True, but scrolling still works.

Thanks, perhaps that's what actually happened and the scrolling was somehow locked by some combinations.  :)
