Yes .. vga=normal solves the problem, because it switches of the framebuffer (which makes a nice bootsplash and an quite big console) and returns to the default BIOS Font (8x12 pixel a character ) Your Monitor scales the small ( 640x480 ) Screen to normal size.
So you can use vga=normal but you renounce the comfort of an framebuffer interface.

i've the same problem on my notebook acer travelmate 630 with geforce2 go
and mdk 10 installed
if i set up vga=normal and i switch to another terminal i see the terminal flikering (it seems out of freq. sync)

but when i start the boot the terminal goes well.. only when i startx and i switch to another term or i go out X the terminal flicks


anyone have an idea to solve this bug?

(i'm trying to uninstall mdk 10 nvidia rpm driver and install it from official Nvidia site, but do the same!)

I had this same problem with 5336 and dvi flat panel. I ended up connecting an ADDITIONAL regular svga cable from the card to the monitor. So I have BOTH the dvi cable and the svga cable to the SAME monitor. Then when I switch to the console, I also toggle the button on the monitor to use the svga cable instead of the dvi cable, and then console is clear. When I go back to X, I toggle the monitor back to dvi.

This all works fine under 2.4.26 of the kernel. I can't get anything to work under 2.6.6 and I have the kernel set to NOT use 4k stacks, but the old 8K stack as before 2.6.6.

i've had this issue and the only fix i found for it (beside disabling the fb) is ---> option "ignoredisplaydevices" "tv"

except i want to use my tv-out....

weird, you'd assume there would be less problem switching between X and framebuffer than between X and physical text mode.

I 've upgradet my System from SuSE 8.2 to SuSE 9.1 (with 2.6.4-52-default Kernel)and the problem remains.
But then i made a internet update for the kernel (to 2.6.4-54-default) and it works!!! (I don't know why)
Now i'm using the pre-compiled drivers provided by nvidia
but i'm not able to compile the modules.

----
PS: For everybody who's upgrading to 2.6 Kernel. Beware of editing the Partition Table (with parted or fdisk) because the kernel returns a wrong Partition Table

I know it's bad form to post to an old thread, and I am sorry for that, but I can't seem to find any fix for this issue.

I'm running on a laptop with a PCIe 6600Go chip.

When I switch to a VT or even exit X, the text terminal is black and I can not get it back. The display works fine if I reenter X again, and the system isn't locked.

I have an AGP-based desktop running a 6200 that does not have this problem, and I have seen some live CD distros that do not exhibit this issue either. This makes me think that it's a setting somewhere on my system, but I can't figure it out.

I have tried adding the vga=normal line to the grub kernel boot line and told the driver to ignore the TV out, still no joy.

So, have there been any news on getting this fixed?

Default Re: Blank virtual terminals

I have exactly the same problem with DVI only - VGA works fine even with vesafb. When switching to virtual terminal, monitor just displays out of sync message with values 86.7 kHz / 81 Hz, which seems to be same as the upper limit in monitor specs.

Both DVI and VGA work correctly with open source nv-driver, so it must be a bug in Nvidia's driver.

My configuration:

Linux Kernel 2.6.23
Xorg 7.2.0
Nvidia driver x86-100.14.19

Monitor is LG L204WT and connected to DVI port of XFX FX5200 128 MB.


Nvidia's driver uses native resolution 1680x1050 @ 60 Hz with VGA without touching any config files. But when using DVI, I must explicitly enable correct modelines and

Option "ModeValidation" "DFP-0: NoMaxPClkCheck".

Without the option above Nvidia's driver cannot make native resolution work on my GPU/DFP combination. But virtual terminals work as they should...

[edit]

I found couple interesting lines doing startx -- -logverbose 5, which are

(--) NVIDIA(0): Connected display device(s) on GeForce FX 5200 at PCI:1:0:0:
(--) NVIDIA(0): LG L204WT (DFP-0)
(--) NVIDIA(0): LG L204WT (DFP-0): 135.0 MHz maximum pixel clock


(--) NVIDIA(0): --- EDID for LG L204WT (DFP-0) ---
(--) NVIDIA(0): EDID maximum pixel clock : 150.0 MHz

Could someone from Nvidia say why this driver doesn't use the same maximum pixel clock that EDID tells?

@faba: your graphics card's maximum pixel clock is 135MHz.

Okay, but 1680x1050 mode still works only with NoMaxPClkCheck.

Yes but then you operate you graphical card in non tested and accepted conditions which could cause problems.
