I upgraded to gentoo-sources-2.6.23-r1 just so I could get uvesafb working on my console but it is not working, the is the error message I pulled from dmsg
| Code: | uvesafb: failed to execute /sbin/v86d
uvesafb: make sure that the v86d helper is installed and executable
uvesafb: Getting VBE info block failed (eax=0x4f00, err=-2)
uvesafb: vbe_init() failed with -22
uvesafb: probe of uvesafb.0 failed with error -22 |
and in case someone is wondering yes I have v86d installed

And do you have | Code: | | CONFIG_INITRAMFS_SOURCE="/usr/share/v86d/initramfs" |
in your kernel .config?

pardon me for asking, but just to be clear, you have
emerged v86d?

In such cases of doubt I always re-emerge klibc to make sure it's uptodate ...

just emerge --sync then re-emerged klibc and it still does not work. I am wondering though what is meant by this line
| Code: | | uvesafb: make sure that the v86d helper is installed and executable |
what is the v86d helper? |

I think this means "/sbin/v86d" ... perhaps you should do what it says and check?

according to this thread CONFIG_FRAMEBUFFER_CONSOLE=y needs to be enabled. It didn't say that on the uvesafb website.
Porblem Solved. |

| I was also having this problem after upgrading my kernel from .28 to .32 ... the solution for me was to switch CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY to y. |

I have exact same problem oon multiple machinse after upgrading to 2.6.39 ( and later r1 and r2)
I heve chacked that "/usr/src/linux" link points to right sources, I have reemerged klibc and v86d
/sbin/v86d exists and is executable. Also, it is being installed anew after each "emerge v86d".
I fon't use ramdisk and expect from kernel to find and execute v86d from the disk of the root partition, as always.
I also checked in kernel .config file for "CONFIG_FRAMEBUFFER_CONSOLE=y" option, which is set.
dmesg | grep uvesafb gives me:
| Quote: | uvesafb: failed to execute /sbin/v86d
uvesafb: make sure that the v86d helper is installed and executable
uvesafb: Getting VBE info block failed (eax=0x4f00, err=-2)
uvesafb: vbe_init() failed with -22
uvesafb: probe of uvesafb.0 failed with error -22 |
Worth pointing out is the fact that this thing behaves differently on different machines:
-on workstation ( Phenom II x4 955BE on AM3 board with inactive AMD graphics and two nVidia cards -7600 GS and 8600 GT and three monitors ) it stopped working after 2.6.37 IIRC
-on server ( Phenom II x4 955BE on AM2+ board with on-board AMD graphics and one small 1280x1024 LCD monitor ) it never worked with uvesafb, but I have to use radeon driver
- on laptop ( Dell Inspiron 1720 with Intel dual core CPU and nVidia based graphics ) it stopped working with kernel 2.6.39*

I tried it.
It is the same as I practiced it before, only difference is that I rolled now v86d in initramfs as described.
And kernel boot parameters are a bit differently expressed now.
It did the trick on my workstation, but it still refuses to work on notebook.

Here is output of "dmesg | grep uvesafb" from notebook:
