------- Comment #4 from [email protected] 2008-05-28 18:50 ------- The Night to contribute little clarity in question.
Bag reveals itself in kernel 2.6.25 and above only.
If compiled "vanila" kernel with config including standard "vesafb" in kernel and "nvidiafb module, that does not be fixed videomode vga=0x317 (and other too).
But, sometimes after several reboot and shutdown "vesafb" is work. After like boot in next time again does not work... With other testing me videocard as GeForce2 MX 400 all work correctly.
Change the files of source kernel:
arch/x86/boot/video-bios.c
arch/x86/boot/video-vesa.c
arch/x86/boot/video-vga.c
arch/x86/boot/video.c
arch/x86/boot/video.h
version from kernel 2.6.24 problem at all does not solve.

OK, thanks but please...

: (switched to email. Please respond via emailed reply-to-all, not via the : bugzilla web interface).

Let's handle this bug via email from now on so the linux-fbdev-devel people get to see it.

I have handled this bug with Denis, so his additional findings are results from this. I have tried to reproduce it but I do not have the hardware he has.
It is a bug in vesafb or VESA mode setting.
I am not able to reproduce this bug on Trident card, 3dfx card, Permedia 2, ATI on-board card (all using vesafb driver).

The current status is that I will try to find someone with the NVidia GeForce 4 MX 4x0 card and borrow it. I hope that Denis' card has some kind of reference board BIOS and not BIOS modified by the card's vendor.

Regards,
Krzysztof
