Did you try undoing each of the steps in that tutorial?

Like, (Note: This is just an undoing of whatever that was done in that tutorial)

sudo apt-get remove v86d
editing the /etc/default/grub file and
1. changing the line 9 which would now read GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=uvesafb:mode_option=1280x1024-24,mtrr=3,scroll=ywrap" back to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
2. and line 18 which would now read - GRUB_GFXMODE=1280x1024 back to GRUB_GFXMODE=1280x1024.

3. gksudo gedit /etc/initramfs-tools/modules and remove the last line reading uvesafb mode_option=1280x1024-24 mtrr=3 scroll=ywrap

4. Remove the line that reads FRAMEBUFFER=y in the /etc/initramfs-tools/conf.d/splash file

5. Then run sudo update-grub2

6. Then run sudo update-initramfs -u

7. Then reboot

At the time of writing this, I have 6+ years of work experience, mostly web projects but also other types. I've used various languages and frameworks: PHP, ASP.NET, C#, SQL Server, Crystal Reports, MySQL, Informix, jQuery, CakePHP, Subversion, Git, and unfortunately even C. I've also played with Sqlite, RoR, Python, GTK (etc) but I have never done a real project with them to call myself an expert. I am of curious nature and like to learn new things, languages, tools and project management related stuff. Lately I've been educating myself about all things Agile which are non-existant in the company I work in (far fowls have fair feathers?).

Several symptoms:
- No splash screen, just a console
- No TTYs available (CTRL+ALT+F1 etc..), just random coloured bars
A while ago, I've used a tutorial to fix Plymouth bootsplash resolution and changed settings I don't quite recall now. What is the proper way to reinstall and reset Plymouth and/or GRUB settings to see if removing my modifications will fix the boot to some acceptable level?

NB: I've updated to 11.10-beta hoping it would fix the problem, but this originally happened on 11.04

Edit: I think the tutorial I followed is this one but I'm not 100% sure. Also, I think the things mentioned in the tutorial are not the only ones I've changed, since I've tried to fix this when it first happened, so I may have messed up other stuff too. This is why I'm looking for a "reset all" solution.

  Can you provide us a link to the tutorial you followed to edit the Plymouth bootsplash resolution?

  Cool :) Did you try undoing each of the steps in that tutorial?

  @nitstorm: Hm, I have to say I didn't.. I figured the update from 10.10 to 11.04 caused the problem so I didn't think my modifications are a problem. Now, I think I might try it... :)

  You probably made some changes to your /etc/default/grub file, so if you are at a loss, give us the contents of it.

  @nitstorm: Well, it seems like the "undo everything" worked. I got the splash back, it's low-res, huge and ugly but I somehow just love it :) Also, the TTYs are back. Would you mind posting your comment as an answer so I can give you some props? :)
