Bug 115783 – [vesafb-tng] kernel 2.6.14-r* vesafb-tng problem with nvidia and 8 bpp depth

• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

[Description Christian Loosli 2005-12-16 08:43:44 UTC]

On my Toshiba Sat. Pro M30 961 I have a problem with Vesafb-tng and newer
(2.6.14) Kernels. X works fine, but the virtual terminals are all blank. 

/proc/fb0/vbe_info says:
Vendor:     NVIDIA Corporation
Product:    NV34 Board - tosh34sf

And while using a 2.6.13 kernel  /proc/fb0/modes contains the line
1280x800-8
With a newer Kernel (2.6.14-r*) I get 
1280x800-0

Other Resolutions (1024x768-32 bpp) work fine.

My kernel config is

 CONFIG_FB_VESA=y
# CONFIG_FB_VESA_STD is not set
CONFIG_FB_VESA_TNG=y
CONFIG_FB_VESA_DEFAULT_MODE="1280x800@72"

(other fb drivers are disabled)

and grubs menu.lst is 

kernel /kernel-2.6.1*-gentoo-r* quiet root=/dev/hda3 video=vesafb:1280x800-8@72


Reproducible: Always
Steps to Reproduce:
1. Use 2.6.14 kernel 
2. Use vesa-fb tng and 8 bpp colour-depth
3. Boot the system

Actual Results:  
Terminal was blank

Expected Results:  
Terminal should appear in 1280x800 with 8bpp colour-depth, 
works with 2.6.13 Kernels

Is this still a problem with the latest version of gentoo-sources?

It is at least with 2.6.17-r4, 
still 

CONFIG_FB_VESA=y
# CONFIG_FB_VESA_STD is not set
CONFIG_FB_VESA_TNG=y

and still 

cat /proc/fb0/modes
640x400-8
640x480-8
800x600-8
1024x768-8
320x200-16
320x200-32
640x480-16
640x480-32
800x600-16
800x600-32
1024x768-16
1024x768-32
1280x800-0

I am using 1024x768 now, 
because it is the highest working
resolution. 

[Comment 3 Jakub Moc (RETIRED) 2007-07-01 01:19:03 UTC]

I can't reproduce this at all with current gentoo-sources.

[Comment 4 Michal Januszewski (RETIRED) 2007-07-01 08:27:29 UTC]

Hopefully uvesafb will be accepted upstream and then we can simply remove vesafb-tng from gentoo-sources without any loss of functionality.

[Comment 5 Michal Januszewski (RETIRED) 2007-10-11 19:56:07 UTC]

I'm closing this bug as WONTFIX, since we're dropping support for vesafb-tng. vesafb-tng has been replaced by uvesafb in gentoo-sources-2.6.23. uvesafb provides the same functionality, but is completely redesigned and hopefully will prove to be free of any bugs that might have been present in vesafb-tng.

If you encounter a similar problem with uvesafb, please open a new bug.
