although the quality of the image is poor (it looks sort of pixelated)

What do you mean by this? I will attach a grab of a 1024x768 framebuffer
image with the livecd-2007.0 theme, which looks okay here!

What about trying a higher frequency, i have 75Hz here! Or is your
monitor not capable of this frequency?


What I mean is that when if fades in it creates artifacts on the screen (is 
this a matter of uvesafb not having acceleration?).  Also the background 
image when I press F2 is not clear.  It looks as if it is a smaller 
resolution stretched over a larger screen.


What about the silent screen does it also look unclear or just the 
verbose screen.


I don't have any artifacts here and the picture is clear, even with the 
connected TV where i only get 1024x768.


I think I can't help you any further here. Maybe you could contact the 
maintainer of uvesafb, splashutils ([EMAIL PROTECTED]). Probably he could 
help you, although he seems busy with other things at the moment.

Daniel

When it boots up it comes up with these errors:

Any ideas?

Just a shot in the dark are you using any kind of tv-out?

I had this problem with tv-out. I specified a resolution of 1280x1024.
When I connect my tv to my box the maximal resolution possible is
1024x768 because the tv-encoder does not offer higher resolutions. So
instead of switching to the next greatest resolution of 1024x768 the
uvesafb driver switches to smallest resolution of 640x480. This
resolution is not available in the emergence theme thus the splash fails!

If you have a problem like this there are existing patches whto the
kernel which are fixing this issue!

What does "cat /sys/devices/platform/uvesafb.0/vbe_modes" say?


Thanks Daniel, I am not using tvout, just a LCD monitor.  You're right, 
there's no 1280x1024 in the above file!  Changed it to 1024x768 and it works, 
although the quality of the image is poor (it looks sort of pixelated).


What controls what resolutions exist in that file?


Output of /usr/src/linux/Documentation/fb/uvesafb.txt

... snip 

2. Caveats and limitations
--

uvesafb is a _generic_ driver which supports a wide variety of video
cards, but which is ultimately limited by the Video BIOS interface.
The most important limitations are:

- Lack of any type of acceleration.
- A strict and limited set of supported video modes.  Often the native
  or most optimal resolution/refresh rate for your setup will not work
  with uvesafb, simply because the Video BIOS doesn't support the
  video mode you want to use.  This can be especially painful with
  widescreen panels, where native video modes don't have the 4:3 aspect
  ratio, which is what most BIOS-es are limited to.
- Adjusting the refresh rate is only possible with a VBE 3.0 compliant
  Video BIOS.  Note that many nVidia Video BIOS-es claim to be VBE 3.0
  compliant, while they simply ignore any refresh rate settings.

. snip .

4. The sysfs interface
--

uvesafb provides several sysfs nodes for configurable parameters and
additional information.

Driver attributes:

/sys/bus/platform/drivers/uvesafb
  - v86d (default: /sbin/v86d)
Path to the v86d executable. v86d is started by uvesafb
if an instance of the daemon isn't already running.

Device attributes:

/sys/bus/platform/drivers/uvesafb/uvesafb.0
  - nocrtc
Use the default refresh rate (60 Hz) if set to 1.

  - oem_product_name
  - oem_product_rev
  - oem_string
  - oem_vendor
Information about the card and its maker.

  - vbe_modes
A list of video modes supported by the Video BIOS along with their
VBE mode numbers in hex.

  - vbe_version
A BCD value indicating the implemented VBE standard.

. snip .


So this depend on the Video Bios of your card and you maybe can't do 
anything about it!


Although 1280x1024 should normally work and i guess you use this 
resolution for your Desktop. How do you generate your initrd? Which card 
do you have?


"dmesg | grep uvesafb" and "fbset --info -v"?

Re: [gentoo-user] uvesafb fails to work

[Matt Edens]

I have had problems getting this to work also, but was able to get it
working finally
after being directed to the authors website and following his instructions.
What I
did was get a 2.6.24 kernel working for me fully with no errors then
proceded to follow
spock's instructions to get uvesafb working properly on both my desktop and
laptop.
Hope this gives you what you need to get it working.

impossibly large size.  My kernel line is:


kernel /kernel-2.6.24-gentoo-r3 root=/dev/sda3 \ 
video=uvesafb:[EMAIL PROTECTED],ywrap,mtrr:4, \ 
splash=silent,fadein,theme:emergence quiet CONSOLE=/dev/tty1

initrd /boot/fbsplash-emergence-1280x1024

Any ideas?


Just a shot in the dark are you using any kind of tv-out?

I had this problem with tv-out. I specified a resolution of 1280x1024. 
When I connect my tv to my box the maximal resolution possible is 
1024x768 because the tv-encoder does not offer higher resolutions. So 
instead of switching to the next greatest resolution of 1024x768 the 
uvesafb driver switches to smallest resolution of 640x480. This 
resolution is not available in the emergence theme thus the splash fails!


If you have a problem like this there are existing patches whto the 
kernel which are fixing this issue!


What does "cat /sys/devices/platform/uvesafb.0/vbe_modes" say?

Daniel
