This is a question about Linux running on a Compulab device named Utilite Pro, but I think it is worth the price to ask this question here to get it solved for any platform (if possible).
I use to work with ConSpy, a wonderful remote control program for the TTY text mode consoles.
If I boot my Utilite to Ubuntu 12.04 with HDMI cable connected to my 720p home screen, I can remotely connect to any TTY, for example the first TTY:
# conspy 1
But if I disconnect the cable and reboot:
luis@utilite-desktop:~$ sudo conspy 1 conspy: screen too large. I only handle up to 200x80.
It seems the resolution goes up to 1080p, and so columns/rows in TTY text mode are too big for ConSpy to manage them.
Same results with Kali v1.0.9.
For what I have read, it seems (incredibly, but it is true) that Linux has terrible problems to change the text mode resolution.
All the methods I have found require for GRUB modifications, but Utilite uses U-Boot instead of GRUB, and it is too cryptic for me to manage (never talk about the risk of saving data to flash).
Isn't there any simpler method to change the TTY text resolution (this is: rows and columns)?
I have tried:
# nano /etc/rc.local
... and then adding:
stty cols 83 rows 40
But results stay the same.
