My Acer Aspire 7720 gave me a fare share of issues on Linux. I won't recommend it for the newbie Linux user.
For the start it would not boot to XWindows...and would pretty much freeze. Can't remember right, but changing to init3 was okay for a while. Finally I managed to make it work by setting noapic acpi=off to the kernel at boot-time. This was done in the grub settings (use the 'a' option when the grub boot screen comes up)
But then my wireless would not work, nor would the Fn keys or the extra keys above the 'normal' keyboard...damn. It turns out that those keys use the APIC controller so either I can boot to init 3 (non graphics) or have graphics but not wireless. What a fork!
After lot of headbanging, I realized that there was an updated BIOS available on the ACER website. Mine was at an old 1.14 version while version 1.42 was available. I booted to windows (thankgod I had not cleaned it away!), a simple utility upgraded BIOS...and sure enough, both Xwindows, WLAN started working fine together. Since realizing that, I removed the noapic acpi=off lines from the /etc/grub.conf
Allz well that ends well
