I am almost entirely sure the monitor and graphics card, physically, arent the problem. For a few reasons, firstly when I installed whitebox the text appeared as normal, this means right through the installation process, and after reboot when it came up with a login prompt, I could also log in and the text would be fine. I then went through a process of removing rpms which I *thought* were redundant for the system I was planning on running. After removing these, I rebooted the system, and the text had become garbled. Addidionally, the bios flash screen and the grub bootloader both appear without corruption, it is only when linux starts to load that the text garbling appears. I dont have any graphics related lines in my grub.conf.
By console, I assume you mean what appears when the machine has finished booting? The machine boots into runlevel 3 and displays a garbled login prompt. If I log in from a seperate machine via ssh, the text is displayed fine.
