I'm on a linux machine without display manager.
I can only login to tty session as standard user. I'm not the administrator of the machine.
Reboot and use grub commands or kernel parameters is not really the best option, mainly because there could be other logged in users via ssh, or there could be running services.
The kernel mode setting is not enabled and the text looks bigger. I want to set a little better resolution without reboot. KMS is not enabled mainly because the radeon non-free firmware is not installed.
All I want is to change the tty resolution as a standard user for my tty session. I will be needing only vesa modes supported. I tried
dpkg-reconfigure console-setup but the results are not good.
So, how do I change the runtime resolution from tty? There must be some way for this.
