Looks like your problem is that your image in your initrd is of the wrong type. Try opening/saving the image in Gimp as a jpg, and then stuff it into the initrd again (using > instead of >>); |

Ok! Thanks for the advice, but here's the problem. I already saved it as jpg and used > to stuff the file!! (Of course I don't want the image concatenated onto the old one!!)
As far as the jpg goes -- I'm using GIMP 2.0. Are there any options for saving jpgs that I should be sure to use or not use? Thanks!
Also, I was looking at the default image for gentoo, and I noticed that its resolution is not 96x96, but rather 186x186 or something like that. Any thoughts?

Yes, I think if you look at the basic howto that starts this thread you will see that dpi must be 96x96.

Somebody tell me what I did wrong. I rechecked my steps but no luck yet.
Need info, let me know. I'm using a 2.6 kernel. It is the one that is stable for me at least.
Edit: Hold that thought. Now the kernel won't boot. Hangs up after replaying journal. Still scratching head on that one. It did work once though, except for the problem above.

if i where you i'd compile a new one (same settings, assuming that you have a settings file saved somewhere) 
i'm going to see if i can patch the recently (like yesterday or something) new stable kernel 2.6.6 with the 2.6.5 one

it's the only error i get when trying to patch 2.6.6, but it's enough to prevent bootsplash from working... maybe the topicstarter can do something with this information to make a patch for 2.6.6? |
You seem to be doing some heavy patchwork to get this going. You may like to try lastest love sources. I can confirm these now work beautifully with bootsplash.

Now I'm off to see if I can make myself a class-act bootsplash like some of the screen shots I have seen here.

Would it be unreasonable to ask someone who has gotten a customized splash image working to detail their process, step by step, using GIMP? I also thought that the problem was the image being formatted incorrectly, but i can't figure out what to do in gimp (ie what jpg save options) will produce a working initrd image.
Thanks in advance for anyone who takes up the call..

omg how stupid can mistakes be lol... made the same mistake i made when i first installed bootsplash on my laptop (see my previous posts in this topic), forgot to add ramdisk support... now it works just fine and also the "oops" is gone

Now here's something weird! That's exactly what I'd BEEN doing. But after your post, I decided, on a lark, to try it on a different image (other than the one I'd been working with). Whoa!! It worked! Maybe my image was somehow corrupted?
Anyway, hopefully I can get the image I want working... I'll try a bit later.

Yes, I have cropped a nice macro photo I took to replace the std silent*.jpg. Works a treat.
I have created a couple of aliases to speed up the process:
| Code: |
alias edbootimg='nano /etc/bootsplash/default/config/bootsplash-1024x768.cfg'
alias mkinitrd='/sbin/splash -s -f /etc/bootsplash/default/config/bootsplash-1024x768.cfg > /boot/initrd-1024x768'
|
Dont know how to screen grab on boot up so I cant post anything. Anyone know?
I also want to change the image behind the grub menu. I can affect it by changing the line in grub.conf
splashimage=(hd0,4)/boot/images/powered-by.xpm.gz
#splashimage=(hd0,4)/boot/images/bug.xpm.gz
but my home grown image comes up in an unrecognisable state. The "powered-by" one works fine. Gimp shows them both to be same size dpi colour depth etc. but two images I tried failed to show properly.
I think its probably a colour depth issue or colour count.
[edit]
Yes , as I suspected, I reduced the image to 16 colours and it works. It aint pretty , but it works.
Gimp: Filters - Web - webify , set to 16 colour not transparency.
Looks like I need to find a more suitable , simpler image for grub bootsplash.
But it all works.

here's a couple of aliases I use for speeding up the typing when poking around with bootsplash. They're in ~/.bashrc
| Code: |
alias edbootimg='nano /etc/bootsplash/default/config/bootsplash-1024x768.cfg'
alias mkinitrd='/sbin/splash -s -f /etc/bootsplash/default/config/bootsplash-1024x768.cfg > /boot/initrd-1024x768'

OK, I have a beautiful grubsplash, I use the same image for both jpeg and silentjpeg which means it drops gently into a transparent mode with the boot text on top.
All this is perfect.
Two oddities remain.
Once the boot process gets to login prompt my nice image gets replaced by the std Gentoo Inc. cows head and the "gentoo" logo in the bottom r-h corner. This somewhat spoils the effect!
Similarly , when I go down for reboot I get silentjpeg from the gentoo directory:
Both these relics are being picked up from /etc/bootsplash/gentoo/images this is no longer the target for default:
| Code: | bash-2.05b# ls -ail /etc/bootsplash/default
524146 lrwxrwxrwx 1 root root 13 May 20 01:18 /etc/bootsplash/default -> livecd-2004.0
bash-2.05b#
|
Why are these relics still coming up?
I guess this is not part of initrd but where are they coming from and how can I change them match my bootsplash theme?
Thanks to the man who knows... |

Glad it got it to work , but you dont need zero compression to make it work (thankfully)
I do mine at 82-84% because this is about the best quality you'll get out of a jpeg. Beyond that it gets rapidly huge with no visible increase in quality.
I have used several different values and it had not caused pbs.
I'm just posting this correction so others don't think it is necessary.
[edit]
After a bit of further testing I can confirm that Floating Point compression is fine (this is better q than integer.) Compression ration is not a factor, tested at 75 82 and 84%.
The only thing that seems to stuff it is Progressive encoding which is pretty unecessary in this context. Apparently sbin/splash cant cope with this format and creates an invalid initrd since even if silentjpeg is OK the whole bootsplash will not work if "jpeg" is not suitable.
Even the dpi does not appear to be an issue, contrary to other posts I have seen. I just recreated my bootsplash with 72 dpi and it came up just the same.
Also note in passing that repeated jpeg saving of an image will quickly deteriorate the qu.
If you have a nice image save it in a non lossy format such as png and always work off that copy. Save to jpeg once only for final version.
Dont feel insulted if you knew that already. Many people dont realise and end up with horrible jpegs and wonder why.
OK, I'm off to splash my boots! Have fun.

@Gentree
Wow!!
I'm positive that I didn't use progressive, so I'm not sure what went wrong. I think I may have used as low as 50% quality, because I checked the preview window and it still looked pretty good without diminishing the quality. Then, of course, the bootsplash failed to work at all. Could you verify this for me (on whether lower quality settings like 50% or less cause your splashes to fail, or is it just me) Also, I might have tried fast integer, and that could have done it. You're right though, that floating point is much higher quality without much cost.
edit
Another thing I tried was 1x1x1x1 subsampling, instead of the default, since 1x1x1x1 doesn't make any changes to the image during the save (This is a non lossy way to save, btw) Do you think that could also be part of why it failed??
/edit
As far as the dpi, I agree, something is fishy. You say it works with 72x72? Well the default image I opened in gimp (the one that comes with bootplash on gentoo) was 186.66x186.66 !!!
Maybe it just works within a range -- because reports claim that 300x300 will NOT work (haven't tried it though). Perhaps 72, 96 & 186.66 are all within the specified legal range of resolutions.
Now that it finally works for me, I'm going to experiment with making more images. Keep you posted.

Ok this should answer about three of the questions posted on this page: Take a look through /etc/conf.d/boootsplash, it's heavily commented and can do lots of stuff. (seperate images per VT, different images on startup/shutdown, etc...)
Thanks, Assgier, for mentioning that, as I had the same problem. |

Sorry to correct you again but this is not accurate. Jpeg uses DCT (discrete cosine tranformation: a sort of Fourrier transform analysis) to analyse an image as an approximation of (co)sinusoildal waveforms. Its lossiness depends on how many frequencies you chose to use. If the highest frequency corresponds to the spacial frequency of your bitmap then it can be non-lossy, but it also ceases to do any compression: you may as well save the bitmap! This is the 100% setting in the save options.
A lot depends on the image content but 50% jpegs can look pretty aweful, although the compression ration is impressive.
There is no sense in using integer or fast-integer compression on modern CPUs. It is a relic from i386+387 days. It is annoying the Gimp defaults to integer and cannot remember the last used compression mode. I doubt anyone using Gentoo is on i386 hardware.
It is true that Gimp does give some fairly biszarre dpi values (I think it actually stores them as p/mm rather than per inch.) In any case I dont see the relavance of this to a screen image, it is the printer resolution. It does not appear to affect bootsplash.
Thanks to Nate_s for the config file , I was not aware of this . Should be a great help. |

| I'm using gentoo-dev-sources 2.6.5-r1, and it has the menu entries for bootsplash - however, i enabled them and it didn't give me a bootsplash. Do i need to patch in bootsplash or is it patched in and i just have to do it the right way? |

I believe there are bootsplash issues on 2.6.5.
I thoroughly recommend 2.6.6-love4 kernel.
This works beautifully with bootsplash and has working rieser4 and nivia Geforce working as well if you need it.
