It isn't a duplicate, as for other people the proposed kernel fixed the problem
and for me it didn't. Really annoying.

Ignore what I said about the package names in the last comment; it is
incorrect. There are linux-image and linux-headers meta packages that

Marco: That's the version of the meta package. The meta package depends
on the correct version of the kernel/headers packages, so updating the
meta packages will install the packages for the proposed kernel. The

linux-meta.

I'm running on a ThinkPad T500 with dual video. Currently have been running
