[Bug 1269595] [NEW] Computer becomes very slow when booted with dual screen

 

Public bug reported:

My computer runs very slow if I have a second monitor connected when I
boot. The slowdown occurs after the logon screen (which is fine). After
trying to find the problem, I noticed that if I boot with only the
laptop screen on and connect the 2nd monitor once Unity is loaded,
everything runs fine. The slowdown makes it hard to extract diagnostics
(or do anything for that matter).

I only use one monitor on at a time.

Acer Aspire one
CPU: Intel Atom N270 (1.6 GHz) (32 bit)
video: Intel® 945GME x86/MMX/SSE2
Ubuntu 13.10
