tty display problems with nvidia and uvesafb

seppukuzushi · 2014-12-31 04:46:20

I'm trying to get my console to display correctly at 1080p; trying to do so through GRUB was always an absolute nightmare.
The console displays fine with nouveau, but nouveau causes the infamous pink line bug, which is simply too irritating to ignore; nouveau is not an option.
In the past, my console has run at low res and incorrect scale with nvidia, but I've ignored the problem since I prefer to use a virtual terminal in X.
Now, if possible, I need to use the actual console for the purposes of module development.
I installed v86d and uvesafb and configured the console for 1920x1080 and 32 bit depth.
The console is displaying with the correct resolution now, but is surrounded by a black border, making the font distorted and extremely difficult to read.

How can I get my console to scale correctly to fullscreen? Any ideas at all. I found nothing in the forums or wiki, and I'm out.
I'm fairly certain there are no vga or video settings in GRUB that are interfering.

Which nvidia driver are you using? Please paste your uvesafb.conf (and your grub config).

# edit: also, what resolution is reported:

cat /sys/class/graphics/fb0/virtual_size

Also, it might help to describe the behaviour more specifically / more in depth...

The rendered part of the console occupies the same space as the GRUB boot menu.
I installed and configured virtualbox a few weeks previously.
I ran "sudo depmod -a" as the wiki / forums indicated it could remedy problems with virtual machines failing to start.
It did fix the virtualbox problem; after reboot, suddenly lightdm *also* initally occupied the same window space as grub.
That was new behaviour. When I logged in to xmonad, the desktop displayed similarly to GRUB.
I hadn't tried fixing it; logging in with root followed by "ps -e | grep X" and "kill -9 <Xpid>" caused X as a whole to start behaving and scaling normally.
I haven't rebooted until attempting to rectify the issue with my console.
The oddity with scaling in lightdm and xmonad still shows up after reboot and is still reparable by killing X.
Killing X doesn't - obviously - have any effect on console scale.

I don't know how Grub works (and, looking at those configs, who would ), but you could try commenting this:

insmod vga

seppukuzushi · 2014-12-31 19:18:36

No dice. I did also notice that my motherboard displays with the same scaling even before GRUB loads. Anything going on there?

jasonwryan · 2014-12-31 19:42:07

I'd be looking it to whatever it was that changes the behaviour when you installed Virtualbox: that seems to be the most likely culprit...
