@Lucazade
I've tried out what you suggested, so I launched a root Kwrite by
entering in the "Run" dialog:
kdesu kwrite
I opened /etc/grub.d/10_linux and replaced the line:
set vt_handoff=vt.handoff=7
with:
set vt_handoff=
I also opened /etc/default/grub and changed the gfxpayload to "keep", as
I saw that mentioned in the 10_linux file above, so my resolution
commands there are now:
GRUB_GFXMODE=1600x1200x32
GRUB_GFXPAYLOAD=keep
My resolution is 1920x1200, but since Grub can only handle Vbe
resolutions and not 16:9 resolutions, I had to use the 4:3 resolution
1600x1200.
Then I've rebuilt the grub configuration, entering at the terminal:
sudo update-grub
After that I've rebooted, picked the 3.5.0-17.26 kernel, and... was baffled to
see that it actually worked! :D
The bootscreen is just fine now, no black screen anymore.
Apparently the Ubuntu kernels can't handle the "vt.handoff=7" option properly,
while the mainline kernels have no problems with it. I would strongly
reccommend to remove the "vt.handoff=7" option from the default
/etc/grub.d/10_linux file.
@all:
If this black screen issue affects you too, just follow my instructions above.
For grub_gfxmode, you can pick the resolution you want, but note that you can
only pick 4:3 resolutions.
