 Posted: Sat Jan 17, 2009 2:14 pm Post subject: uvesafb framebuffer support doesn't work [solved] |
 |
|
Hi,
I want to have a nice background during the boot process but it doesn't work. I read the wiki carefully and also this guide.
I use the following versions:
- sys-kernel/vanilla-sources-2.6.27.10
- x11-drivers/ati-drivers-8.532
- sys-apps/v86d-0.1.9
- media-gfx/splashutils-1.5.4.2 (emerged with use flag fbcondecor)
The kernel supports the following options:
CONFIG_FB_MODE_HELPERS=y
# CONFIG_FB_TILEBLITTING is not set
CONFIG_FB_UVESA=y
CONFIG_CONNECTOR=y
CONFIG_BLK_DEV_INITRD=y
CONFIG_INITRAMFS_SOURCE="/usr/share/v86d/initramfs"
The kernel is called by grub with: | Code: | kernel /vmlinuz root=/dev/sda3 splash=verbose,theme:emergence video=uvesafb:1024x768-32@75,mtrr:3,ywrap console=tty1
initrd /boot/initrd |
/boot/initrd contains: | Code: | # zcat /boot/initrd | cpio --list

Could someone help me?

Ok, let's get the obvious question out the way first 
I take it that "kernel" and "video" are actually on the same line in your grub.conf?
I only ask as in the text provided they look to be on different lines? |

Both statements are on the same line.
I forgot to mention, that fbcondecor is added to the boot run-level. |

You could try to add:
CONFIG_VGA_CONSOLE=y
CONFIG_FB_CON_DECOR=y |

| CONFIG_VGA_CONSOLE=y is already set. But the option CONFIG_FB_CON_DECOR isn't available. Which kernel version do you use? |

I guess that you need v86d in your initrd.
Make an empty dir. Lets say we will use /root/my_initrd for that purpose. Then make a dir /root/my_initrd/sbin and copy /sbin/v86d there. Then create your initrd with splash_geninitramfs like previously but add "-o /root/my_initrd" to the options.[/code] |

I'm using 2.6.28-gentoo.
However that wiki seems to miss the klibc-part described in Spock's installation guide below (not sure how important that is though):
| Quote: | 1. cd /usr/src/linux
2. configure the kernel; in the "Device Drivers" section select:
Connector - unified userspace <-> kernelspace linker and
Graphics support ---> Support for frame buffer devices ---> Userspace VESA VGA graphics support
(that's CONFIG_CONNECTOR=y and CONFIG_FB_UVESA=y)
3. build the kernel: make
4. remerge klibc: emerge klibc
note: This step is necessary because klibc has to be compiled against a kernel tree that includes uvesafb. You only need to do this once, i.e. you won't have to remerge klibc every time you install a new kernel or a new kernel module.
5. install v86d: emerge v86d
6. reconfigure your kernel; in the "General Setup" section select:
Initial RAM filesystem and RAM disk (initramfs/initrd) support
and use /usr/share/v86d/initramfs in Initramfs source file(s).
(that's CONFIG_INITRAMFS_SOURCE="/usr/share/v86d/initramfs")
7. rebuild the kernel: make, and install it
8. add video=uvesafb:1024x768-32,mtrr:3,ywrap (or similar) to your kernel command line
9. reboot and enjoy uvesafb 
|
Also the following link gives information about installing themes and such:
http://www.tyr.cz/htdocs/tyr/xslt-blog/article.html?article=fbcondecor
This helped me a lot at least. |

| I'm also running 2.6.28 and tried uvesafb and didn't do 4, 6 and 7. But I did generate an initrd with v86d like described above. I thinks it's easier this way.... |

I generated a new initrd | Code: | # ls -l /boot/myinitrd

And changed my grub.conf like this | Code: | kernel /vmlinuz root=/dev/sda3 splash=verbose,theme:emergence video=uvesafb:10$
initrd /boot/myinitrd/img.cpio.gz |
But it doesn't help. The background is still black. What about the following: | Code: | # splash_manager --theme=emergence --cmd=set --tty=1
Failed to open the fbcon_decor control device.
Failed to open the fbcon_decor control device. |
And what about the hint in the wiki | Code: | | Fbcondecor is a kernel patch which allows the display of different background pictures on framebuffer consoles. The patch is included with gentoo kernel sources, and enabled though the CONFIG_FB_CON_DECOR option (Device Drivers -> Graphics support -> Console display driver support -> Support for the Framebuffer Console Decorations). |
It seem's like fbcondecor isn't supported by vanilla sources. |

| Problem is solved. I switched to gentoo-sources and activated the option CONFIG_FB_CON_DECOR=y. |

Hi
framebuffer does not work to me
I read this wiki.
I use the following versions:
- sys-kernel/tuxonice-sources-2.6.24-r9
- x11-drivers/ati-drivers-8.501
- sys-apps/v86d-0.1.9
- media-gfx/splashutils-1.5.4.2 (emerged with use flag fbcondecor)
I followed the steps described in the linkof wiki:
- I have the following options enabled in the kernel
CONFIG_CONNECTOR=y
CONFIG_FB_UVESA=y
CONFIG_FB_CON_DECOR=y
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_FB_VESA=y
- I run make
- I run emerge klibc
- I run emerge v86d but does not work
the error is:

Well - as the error message clearly states: your kernel does not seem to support uvesafb ...
You can either try to patch this kernel or use another kernel like gentoo-sources ...
