nvidia driver and framebuffer coexisting?
 
See topic. Is there any way to make this work? I'd really like to have framebuffer support in the console when I'm not running X. I'm using the 8178 driver and even though I'm pretty sure I compiled in the VESA FB support, it doesn't seem to be working.

Does anyone have any suggestions on how to make this work? What I might be overlooking?

  • For kernel 2.6 enable options:
    Device Drivers->Graphics support->
    * Support for frame buffer devices
    * VESA VGA graphics support
    L> Console display driver support->
    * Video mode selection support
    * Framebuffer Console support
    L> Logo configuration
    Here you can enable penguin picture which will appear at boot. This is optional
    setting.

Yeah, I already have all those options compiled into the kernel. Here's the line I use in grub.conf:

kernel (hd0,1)/bzImage ro root=/dev/sda5 video=vesafb:ywrap,pmipal,1400x1050-16@85

Further, I get a framebuffer error at the very end of boot which says "Failed to open /dev/fb0 or /dev/fb0 for reading. Can't open /dev/fbsplash" Two things come to mind here - obviously for the first, this should be available much earlier in the boot sequence. Second, obviously if it's not available, then the framebuffer isn't working period.

But going to /dev, I have fbsplash as a c-node, and fb0 which is a symlink to /dev/fb/0, another c-node. For the record...

fb/0 - MAJOR: 29, MINOR: 0
fbsplash - MAJOR 10, MINOR: 63

The grubsplash works.
splashimage=(hd0,1)/grub/gentoo.xpm.gz

Check directory/file access rights.

World everything? It's a laptop, so I'm not really concerned about another user writing gobbledygook to it. I think it was 755 when I looked at it last night. What should it be?

Obviously /dev isn't an issue, so we're talking specifically about /dev/fb/0 and /dev/fbsplash.

1. do you use "vesa-tng" or not? (if not... get it!)
2. Do you have a 5XXX/6XXX Card?

It's a GeForce Go 6200 TE.

/dev/fbsplash's perms are set to 660.
/dev/fb/0's perms are set to 644.

I'll have to check later if vesa-tng is compiled in or not. My wife has the laptop, and she's on campus right now.

... (so you probalby don't have vesa-tng)
so, using "video=vesafb:ywrap,pmipal,1400x1050-16@85" is probably wrong...
try "vga=794" instead.

BTW, if it's a laptop, why do you need 85HZ? or do you use an external CRT?
