[SOLVED] How to activate GUI->xterm.js in a debian 12 VM?

[aaralves]

In order to make xterm.js available, I have edited the VM /etc/default/grub and now the contentes are:
-----------
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_CMDLINE_LINUX_DEFAULT="quiet console=tty0 console=ttyS0,115200"
GRUB_TERMINAL="console serial"
GRUB_SERIAL_COMMAND="serial --speed=115200"
-----------

At the VM I have executed >update-grub

At the ProxMox GUI, Hardware->Display was changed from Default to "Serial terminal 0"

After rebooting the VM, the GUI Console->Xterm.js is now enabled but not working.
xterm.js window becomes stucked with the messge:
"starting serial terminal on interface serial0"
The noVNC consle is not working also and shows the same message.

Does anyone help me to fix this?

Did you?: Add Hardware --> Serial Port --> Serial Port 0


In addition to changing the display type, you must also add the serial hardware.

Hi,
Now, xterm.js works fine.

Ok, with both posts I could enable the xterm.js on a Ubuntu 22.04.1 LTS (We need to Upgrade, I know)

But the text looks very bad. Super low resolution... expected from serial tty off course , but the shell on the ProxMox host machine looks super sharp, with a very nice resolution. I Think it uses a pty thing

How to make it look better? Enable and use this pty thing, is there a way? The host machine looks amazing. Look at the difference
