Installing Ubuntu 15.04

Fresh Install

To do a new installation, insert the DVD included in this issue into the drive with the DVD with the label facing up for 64-bit architecture and facing down for 32-bit architecture, and then turn off the computer. Then, turn it back on and immediately hold down the Shift key, and you will get to the Ubuntu boot menu. Here you can make a language selection using the F keys to set language, keymap, and boot parameters.

Press F6 (Other Options ) on the Ubuntu boot menu so that you do not land on the Ubuntu desktop. The window has a Boot Options line at the bottom (Figure 2). Enter the boot options mentioned here instead of the default ones quiet splash .

Figure 2: If booting doesn't work, you can adjust boot option in the Ubuntu boot menu.

The nomodest , radeon.modeset , nvidia.modeset=0 or nouveau.modeset=0 options help if you have graphics problems and the screen stays black. The acpi=off boot option fixes power management problems on older computers.

Ubuntu on Trial

If you do not want to Install Ubuntu right away, you can Try Ubuntu without installing (Figure 3). In Live mode, Ubuntu copies only the necessary programs into memory and executes them from there. Booting takes noticeably longer than with the installed version, and the system as a whole is a bit slower, but you can test Ubuntu 15.04 with little risk. Also, look at the bundled applications to see whether Ubuntu supports your hardware (printers, scanners, wireless, and graphics cards).

Figure 3: Choose Try Ubuntu to run a Live instance on your computer without installing anything.

Ubuntu 15.04 loads only the 3D version of the Unity desktop and uses LLVMpipe for slower machines, creating sluggish responses on some older computers (cause for a recommended desktop replacement).
