No signal to monitor while in console mode with an nvidia 8500/8600 unless vga=795 is used

[Peter Fletcher]

I've just installed Feisty Fawn AMD64 version on my new box.

There are a few messages from Grub and the kernel, and the X server runs fine,
but whenever the console should appear (during boot and shutdown), my monitor
switches off with "no signal".

Also, if you choose "console login" from the X login screen, the display also disappears.

Here's some info:

CPU: 4800+ dual-core AMD
GPU: NVidia 8500
Motherboard: Gigabyte
Screen: Benq 19" wide LCD, 1440x900

Thank you for your bug report.

Peter:
If you boot with the additional
vga=795
option does a "console login" from the X login screen work?

Peter:
Could you also upload your
/etc/X11/xorg.conf
file?

Yes, that fixes the problem completely, thanks:
the splash screen comes up, and console login works.

More info about my system:

OS=Kubuntu 7.04
Screen = BENQ FP92W, using DSUB connector

Kind regards,

Peter Fletcher.

Might be dup of bug #32389 ... Hard to tell what that bug is about because it has so many comments...

[Sitsofe Wheeler (sitsofe)]

(PS: You can edit /boot/grub/menu.lst to make the change permenant on non safe mode kernels)

Bug #86666 is another dup candidate...

(Subscribing Timo)
Is this bug a dup of Bug #86666 ?

[Timo Jyrinki (timo-jyrinki)]

Not a dupe of 86666, since it's about a complete crash after grub if not using vga= parameter.

(Might be a dup of Bug #112975 ...)

Related to bug #140759?

This bug is a duplicate of bug 147623 in libx86 that was the source of multiple issues with usplash and consoles with nvidia 8xxx cards, it is now fixed in Hardy.
