Re: [gentoo-user] Kernel boot messages are no longer displayed

 Hi all,

 Since kernel 3.12.13 (3.12.13-gentoo), the kernel boot messages have
 disappeared, i.e. they are no longer displayed at boot time. All I get
 is a line like Loading kernel 3.12.13. (I just upgraded to
 3.12.20-gentoo, so now it's something like Loading kernel 3.12.20.)

 I have no idea why. I checked my grub config and it does not add a
 quiet argument. I see nothing in /etc/rc.conf about quiet (or
 verbose). And X86_VERBOSE_BOOTUP is set to 'y'. I also looked for
 quiet, boot, and messages (while running make xconfig) and
 nothing untoward showed up.

 How do I get back to a normal and sane boot process?

Hi, I also experienced this change earlier this year, and it seems the
old behavior can be restored by setting loglevel=7 in kernel cmdline.
Actually, not printing that much message can lead to a small
performance gain, as some console drivers tend to not be very fast;
but you certainly can have the messages if you want.

Hope that helps~

What version was the previous kernel? These two options appeared
recently and are capable of clobbering your console:

  * Mark VGA/VBE/EFI FB as generic system framebuffer (X86_SYSFB)
  * Simple framebuffer support (FB_SIMPLE)

The first time I set them incorrectly, I got a blank screen until XFCE
popped up.

Ka-ching! X86_SYSFB was indeed set and after I enabled FB_SIMPLE,
everything went back to normal. Thanks Michael!
