I get an error from grub on boot 'No server sprcified, No suitable video mode found' And the plymouth splash doesn't come up. But it is visible during shutdown, not at boot time.

While booting I expect to see the graphical splash without errors.

When I boot Ubuntu I get two errors from grub telling that no server has been specified and no suitable video mode found. Although I have edited the grub file and added the resolution of my monitor there. As of now I have turned grub boot into text only and the errors went away but the boot process is still minus a graphical splash.
