Bug#317544: debian-installer: Using ALT-Fn keys during framebufer install messes up screen making installer unusable
During my first attempt to install Debian on my system, the installer
defaulted to using a framebuffer mode. During installation(specifically
when I was supposed to enter the host name, even though I dont think
this matters) I tried to use Alt-F2, Alt-f3 to see the debug messages.
Unfortunately, the screen messed up totally, the cursor shifted to a top
right part of the screen and my input was getting displayed there. There
were red blocks everywhere. After entering the hostname, i couldnt see
anything happening, the whole screen was filled with random blocks etc.
I had to abort installation. I read up on the bootup parameters, and
switched framebuffer off during install, and the installation went off
flawlessly this time.
I wasn't using any boot parameters at all. In the second attempt, I only
used the parameter to set framebuffer off. So this was using the default
