Why doesn't tty work after some time?

Question

linux

After sleep mode or some time tty on the buttons ctrl + alt + f1..6 the text that was last opened on it and that's it, nothing else. All tty's are the same. How to solve this problem

Answer 1

Well, finally I tested the solution given above in the link. Well, that's all right. Indeed, after performing these actions, tty stopped hanging.
So what I did was:
edit /etc/default/grub
- uncomment the line GRUB_TERMINAL=console. It may work differently for you (I have Calculate Linux), but the meaning is the same - you need to specify in the grub config so that it does not work in graphical mode, but in text mode. Scary, but reliable.
- in the GRUB_CMDLINE_LINUX line at the very end, add the text "nomodeset i915.modeset=0 vga=XXX", where XXX is the desired video mode supported by the video card. Mode numbers are looked by the command

# hwinfo --framebuffer
...
  Mode 0x037d: 1920x1200 (+1920), 8 bits
  Mode 0x037e: 1920x1200 (+3840), 16 bits
  Mode 0x037f: 1920x1200 (+7680), 24 bits

and converted to decimal. More about this is written here .
After that, everything works as usual :)
