Created attachment 314093 [details] Kernel .config Hello. I'm running 3.4.0 kernel with fbcondecor and boot splash (initramfs generated by genkernel).

1) Does this happen on newer kernels like stable 3.5.7 or testing 3.6.5? > I've found a workaround: if I hit Alt+F1 during initramfs bootsplash (so I see the console) then everything works fine later. This almost sounds like a problem in the theme, although I dunno if copying the theme would be able to cause that. 2) But just to see if it matters, have you tried a different theme? 3) Which version of genkernel (and the fb-related packages) are you using? Can you try a different version for these?
Please comment with requested info if this is still an issue with later kernels and we will reopen.
Sorry, I've switched to dracut and plymouth a while ago due to other issues with udev and systemd, so this bug probably should be closed.
