Burg installation disables Plymouth about burg HOT 7 CLOSED

Yeah, this is a known issue. To fix it in the current version, add this to
/etc/default/burg:

GRUB_GFXPAYLOAD_LINUX=text

and then update-burg. This problem should be gone in the next version.

Ok, with this option I have plymouth enabled, but with a bad resolution.
This is my burg file content:

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
GRUB_GFXMODE=1280x1024
GRUB_GFXPAYLOAD_LINUX=text

It seems the problem reported here: 
https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/551013

Can I fix it with BURG installed??

That seems like a linux driver issue, I don't think it can be fixed by the boot 
loader.

BTW, you can try the method described in #73 by Tomas Šaduikis, adding a 
vga=xxx
parameter to GRUB_CMDLINE_LINUX. You also need to set GRUB_GFXPAYLOAD_LINUX to 
the
specified resolution or use GRUB_LINUX16:

GRUB_GFXMODE=1280x1024
GRUB_GFXMODE_LINUX=1280x1024
GRUB_CMDLINE_LINUX=" vga=xxx"

or

GRUB_GFXMODE=1280x1024
GRUB_GFXMODE_LINUX=text
GRUB_LINUX16=true
GRUB_CMDLINE_LINUX=" vga=xxx"

As there is no further reports, I assume this issue is fixed.

Plymouth is showing, but in bad resolution. I think its a linux driver issue.

Thanks.
