[SOLVED] Nvidia twinview framebuffer problem

I've got odd problem. When I add vga=775 to kernel line in grub.cfg (I wanted to have higer resolution in terminal) then I can't turn on the twinview in nvidia-settings. I get some errors about metamodes which are tried to load.
Why does it happen? What should I do to have higer resolution in console and at the same time ability to turn on the twinview?

I don't see how the framebuffer matters.

Anyway, without *exact* error messages, how do you expect anyone can help you?

Re: [SOLVED] Nvidia twinview framebuffer problem

I get this error in small window - "Failed to set MetaMode (1) 'DFP-0: nvidia-auto-select @1920x1080 +1920+0, DFP-1: nvidia-auto-select @1920x1200 +0+0' (Mode 3840x1200, id: 86) on X screen 0."

In grub.cfg:
kernel /boot/vmlinuz-linux root=/dev/sda1 ro vga=773

Without last "vga=773" twinview works.

Additionaly with vga=773 added and after an attempt of enable the twinview I can notice that some things stop work as earlier. I mean - sometimes  windows which I closed leave horizontal stripes on the screen.

In Xorg log I get:

[    73.711] (EE) NVIDIA(0): Failed to allocate primary buffer: out of memory.
[    73.712] (EE) NVIDIA(0):  *** Aborting ***
[    73.718] (II) NVIDIA(0): Setting mode "nvidia-auto-select"

xorg.conf is a file generated by nvidia-xconfig

Re: [SOLVED] Nvidia twinview framebuffer problem

Now that's a lot better, having this info, Google immediately found something. Though this also means you could've easily found this yourself, instead of asking here . Anyway: http://www.nvnews.net/vbulletin/showthr … ?p=2269332 <- not really sure how much of a solution that is, but if you don't notice anything weird when using that option, then ok. Oh, and if you're not using grub2, but grub1, that option goes to the kernel line in the grub1 config.

Re: [SOLVED] Nvidia twinview framebuffer problem

Thank You very much! It works.

I added nopat to kernel line:
kernel /boot/vmlinuz-linux root=/dev/sda1 ro nopat vga=773
