Public bug reported:

When installing Ubuntu 14.04 LTS Desktop from an install DVD isoimage on my 
machine

ubuntu-14.04.4-desktop-amd64.iso


HP Workstation Z240 Tower

CPU: Intel Xeon E3-1245v5 4C (3.50GHz, 8MB Cache, 2133 MHz FSB)
RAM: 32GB DDR4-2133 ECC (2x 16GB)
HDD1: 1TB SATA III, 7.200 U/min
HDD2: 1TB SATA III, 7.200 U/min
Graphic: NVIDIA Quadro K2200 4GB, PCIe
Optical Drive: DVD+-RW Slim SuperMulti, SATA
LAN: 10/100/1000 MBit onBoard

I encountered during installation problems with screen display of
characters. Many characters appeared in the wrong color (white on grey
instead of black on grey or other similar color changes) and so became
nearly unreadable. Nevertheless I completed the installation mostly by
guessing the unreadable parts (but could not use custom partitioning
because it was too risky to enter the necessary data without being able
to read the displayed texts).

The installed version showed similar color corruptions in all places
where text was displayed. After installing the HP driver CD
(hp_drivercd_ubuntu14_sp74252.iso) from the HP Homepage, the problem
disappeared. Nevertheless I think the bug should be fixed, as it's a bit
risky to go through the installation half blind.
