Comment 6 for bug 1507255

How do I tell if this Lenovo M58p has the Intel GMA4500 chip?
Wily gives me fits with hashing. Can't read text even.
Xenial slightly better. Text sent out by Ubuntu is totally hashed. Text I type in on the terminal window is readable. Wallpaper and images are hashed unintelligible.

Current workaround, this is Xenial with 3.17.8031708 installed from Ubuntu Kernels:
DISTRIB_RELEASE=15.10
DISTRIB_CODENAME=wily

The 4.1.0-16 is totally unusable.
Oddly uname-a reports

which doesn't seem to match ls /boot? And doesn't match the .deb:
linux-image-3.17.1-031701-generic_3.17.1-031701.201410150735_amd64.deb

Anyway, it works, just I'm not testing Xenial...... I've Acer and HP laptops running Wily fine. Will try Xenial on them time permitting.
