[SOLVED] Laptop does not display tty in full screen

Hello,

I installed Arch yesterday on Acer aspire 5520. The kernel starts printing utilising the whole screen. When udev finishes loading discovering devices and changes the resolution the effective size doesn't change. In other words the resolution is good but tty is using about 70% of the screen. Xorg works perfectly. There's also nothing in any of the logs.

In case I was not clear about the issue:
TTY
------------------------------------
|     usable       |            |
|      space       |            |
|______________|            |
|                                  |
|      blank                     |
-----------------------------------

Xorg
-----------------------------------
|                                  |
|                                  |
|         all usable           |
|                                  |
|                                  |
------------------------------------

More info would help, such as what video chip you have and what driver you are using.  Perhaps simply tweaking KMS resolution would help.

I figured someone will ask for more info.

Graphic card is some Geforce 7000M model, running nouveau drivers.

Just tried get-edid, but it had failed when it tried to read EDID. Here's what it said:

EDIT:
If it's of any relevance ttys behave the sme on Arch linux (and void linux) install cd, though Gentoo is fine.

Try adding "nouveau" to the MODULES section in /etc/mkinitcpio.conf and regenerate your initrd

"fbset -g 1280 800 1280 800 32" worked. Appended "video=128x800@60" to kernel command line and all is well. early KMS did not help.

i should have RTFM. Thanks.
