cannot update to version 3.0.0

Hi Pavel,
UPDATE: After rebooting my machine and restarting the VM it all of a
sudden supported the resolution and uses now the native 5120 x 1440
DQHD resolution on my screen!! So for Linux it is still needed to
reboot te system for changes like that. I was not aware of that.
any way,  your tip for changing the vgamem but not the other parameters
really worked! 
many thanks for your assistance!
kind regards,
