HP-2133 Upgrade to Ubuntu 14.04 -- an important prerequisite

Posted 11-22-2014 at 08:30 PM by flshope

The HP-2133 Mini-note PC is a laptop computer with a 9-in. viewable diagonal screen. It has a single-core 1.2 MHz processor with 2 GB RAM and a 120 GB disk. The machine came with SUSE Enterprise Desktop 10 installed, a poor choice because none of the peripherals worked. Prior to the present upgrade, the machine was running Ubuntu 12.04 LTS with the Unity desktop.

Most recently I upgraded the machine to Ubuntu 14.04 LTS. The install was eventually successful, but the first try was aborted because the installer program said the graphics hardware would not support Unity. Specifically, it referred me to a web site that recommended installing Gnome Session Fallback Services under 12.04:

https://wiki.ubuntu.com/X/Bugs/Updat...ningForUnity3D

If I had known about Gnome Session Fallback when I first installed 12.04, I would have installed it immediately. While Unity worked under 12.04, it was slow compared to my desktop machines.

So I installed 'gnome-session-fallback-services' under the Ubuntu Software Center program. The result was a choice of desktops at log-on: Unity, Gnome (Metacity) and Gnome (Compiz). The Metacity version provided what I was used to thinking of as the classic Gnome desktop. The desktop response was much much better under Gnome.

When I tried the 14.04 upgrade again, it proceeded without incident. The download took about 15 minutes with AT&T U-verse running at about 7.7 Mb/s. The install took about 4 hours.

The upgraded machine is working nicely with Gnome Session Flashback Services under 14.04.

So far I have noticed only one anomaly (difference?) compared to 12.04. I maintain the machine using an external keyboard, mouse, and monitor controlled from an IOGear KVM switch. Under 14.04, the display manager treats the laptop display and the external monitor as two different displays. What appears on the laptop screen does not automatically appear on the external monitor, though you can slide windows from the laptop to the external monitor. This may be a configuration choice, but I have yet to figure out how to make both display the desktop simultaneously.
