Text consoles stay black
After changing my xorg.conf to make use of Nvidia's TwinView feature with
my TV, which works otherwise fine, tty1-6 stay black (Well, OK, there are
some green little boxes on tty1 ^^). This is what I inserting in the
Device section of my xorg.conf:
Option "TwinView" "true"
Option "TwinViewOrientation" "Clone"
Option "TVOutFormat" "COMPOSITE"
Option "TVStandard" "PAL-B"
Option "SecondMonitorHorizSync" "30-50"
Option "SecondMonitorVertRefresh" "60"
Option "MetaModes"
"1280x1024,1024x768;1024x768,1024x768;800x600,800x6 00;640x480,640x480"
Strangely, when I comment it out again, I have to do a complete reboot to
see the consoles, restarting the X server is not enough. Any idea what
causes these problems and how I can fix it?
Regards,
ubi

Which version of the evil binary-only nVidia modules are you using?
Which version of the kernel are you using? Which console are you using?
Straight VGA, VESA framebuffer, nv framebuffer, or something else? I've
had some problems with console switching and nvidia, but that was a long
time ago, around the 6627 build.

The evil nVidia module does strange things to the video chipset, of
course. If you're using the nv framebuffer console, starting X with
nvidia may screw up the nv framebuffers. I haven't had any problems
with straight VGA or VESA framebuffer and a TwinView-enabled nVidia
card for the last 1.5 years.

I'm using the vicious and wicked 8776 build with a 2.6.17-11-generic from
Ubuntu. I specified the console resolution with the kernel parameter
vga=791, that means I'm using a VESA framebuffer, right?

I just tried setting vga=normal in my kernel options and the problem is
gone, but a 80x25 lines console makes no real sense on my 19" screen...
Btw, does vga=normal mean the "straight VGA" frambuffer you were talking
about?

Yep, vga=NNN gets you straight VGA text-only modes if NNN < 0x100 and
VESA framebuffer modes if NNN >= 0x300. Docs are in
/usr/src/linux/Documentation/fb/vesafb.txt . Build 8776 of the evil
nvidia modules works fine here, been using it ever since it was marked
stable in Gentoo.

If X is running, virtual consoles are sorta superfluous as you can
always start another xterm/konsole/eterm. If you want something that's
faster than VESA framebuffer and more than 80x25, see what you can get
from vga=ask. HTH,

So it must be something specific to my machine. I'm going to experiment a
bit.

No, they're not! When the X server gets unusable, for example because of a
freezed fullscreen X app, the consoles are often the only way to get
control of the system by killing the app from there. At least I have
experienced this case often.

Yes, I'm going to try that, thx! If all else fails, I might also
settle for 'normal', as it's only for rescue purposes anyway.

Or the graphics card, or something in your X config.

....then X is usually completely hosed, and unresponsive to keyboard
events like Ctrl-Alt-F?. At least that's been my experience. Alt-SysRq
might still work, but that one doesn't involve X.

Strange. IME, when X has hosed itself in that way, the easiest way to
regain control of the system without rebooting is to ssh in from another
machine on the LAN and kill -9 X. That doesn't work 100% of the time,
natch. If you're experiencing extreme X instability, it might be time
to fiddle with xorg.conf or try a different version of the evil nVidia
modules.

....back in the day, all we had was 80x24, black-and-white, and we liked
it! Uphill in the snow, both ways, with only 64k of address space and
8-bit registers!
