Comment # 18 on bug 978973 from Roman Bysh

New test provides good results

I no longer have any vga= entries in openSUSE 13.2 and Tumbleweed.
Both openSUSE 13.2 and Tumbleweed are on separate drives.

Test 1
I set my sata cables so that 13.2 is primary with Tumbleweed on the second
drive.
The desktop is powered up and Tumbleweed is selected from the 13.2 grub2 menu.
I see a flashing cursor in the top left corner of the screen during the boot
process and is followed by the boot splash with the three question marks.

The desktop is then shutdown and rebooted. This time I select 13.2. The boot
process appears normal with the correct resolution and no flashing cursor.

Test 2
I reversed the sata cables so that my 2nd drive with Tumbleweed is the primary
and openSUSE 13.2 is the second drive.
The desktop is powered up and Tumbleweed is selected from the Tumbleweed grub2
menu. This time Tumbleweed boot process looks normal with the correct
resolution.

When I shutdown, reboot and select 13.2 from the Tumbleweed menu the flashing
cursor appears in the top left corner and I have HUGE letters for the console
prompt when I press ctrl+alt+F1.

When I add vga=795 to the kernel options whatever openSUSE distro is on the
second drive no longer shows the flashing cursor in the the left window and
three question marks.
