[SOLVED]How to get higher Framebuffer than 1024x768 with nvidia module
Hello,
when I first installed Arch it loaded nouveau module for my nvidia graphicscard during boot via udev.
Everything looked fine and it seemed like it was using my nativ resolution of 1280x800 for conole.
Now with "nvidia" it doesn't look as pretty anymore since it uses the vga=773 (1024x768) framebuffer
from the Kernel Line which loooks a little bit distorted on a widescreen monitor. When I run the
HDT (Hardware Detection Tool) from Syslinux it lists all possible vesa framebuffers but 1024x768 seems
to be the max. So why is it possible with nouveau and not with the prop. nvidia driver? Is there a work
around?
Is this impossible because prop. graphics driver don't use the open driver stack?
Kind Regards,
blackout23

It's impossible because nvidia does not provide a fbcon driver that would work on top of their modesetting. Because of that you're limited to the resolutions in your graphic card's vbios. Sometimes the vbios has widescreen resolutions, many times it doesn't.

640x400-8, 0x0100
640x480-8, 0x0101
800x600-8, 0x0103
1024x768-8, 0x0105
320x200-16, 0x010e
320x200-32, 0x010f
640x480-16, 0x0111
640x480-32, 0x0112
800x600-16, 0x0114
800x600-32, 0x0115
1024x768-16, 0x0117
1024x768-32, 0x0118
320x200-8, 0x0130
320x400-8, 0x0131
320x400-16, 0x0132
320x400-32, 0x0133
320x240-8, 0x0134
320x240-16, 0x0135
320x240-32, 0x0136
640x400-16, 0x013d
640x400-32, 0x013eRegards,

To bad that nouveau is very slow at least on my laptop. Gnome Shell starts stuttering, when I open the Dash with the Super-Key.

It won't work as Gusar has said.
If you're using the nvidia blog you are limited to what the vbios supports, which is usually very limited. Some GPUs can be flashed to support more but that's a whole other topic.
Edit: I spent awhile looking into this too when using my 9600GT, no cigar.

Oh, sorry, I didn't see that, because it works well on my laptop. My video card is Nvidia GForce G105M.

Yup, some cards have the various resolutions supported, some don't. Pot luck really.
