I have been installing a new Ubuntu server on some old hardware at work this week (HP Proliant DL360 G4) to configure a Free-Radius server for our site-wide WiFi solution; however I fell at the first hurdle!
After installing Ubuntu as normal and rebooting the server, I was presented with a black screen displaying “Cannot display this video mode”. Very annoying!
So what I managed to do was to log in to the server by holding down “shift” straight after BIOS and before the OS tried to boot. This bought me into the GRUB Menu screen where I pressed “e” to edit the boot parameters of the kernel. I added:
to the boot line and then pressed F10 to boot the machine.
My graphics now displayed and I was able to install SSH to ensure I could get access remotely!
Now I needed to add these boot options permanently into the GRUB menu. I ran
“sudo nano /etc/default/grub”
and edited the following lines:
I then uncommented this line:
Saved the file and then ran:
sudo reboot now
My display then worked on the console, and as an added plus I also have full console access to my machine over the standard iLO1 without the need for an iLO Advanced Pack from HP!
Kudos to this bloke for pointing me in the right direction!
