Shoddy Laptop? Linux 4.4 Gets Patch To Support ESC Key On Lenovo Laptop
Written by Michael Larabel in Linux Kernel on 14 November 2015 at 07:18 AM EST. 13 Comments
With the Linux 4.4 kernel the Lenovo Yoga 3 laptop owners out there will finally have support for using their ESC key.

Darren Hart sent in the x86 platform driver updates for Linux 4.4 already but he ended up sending in a second pull request as we near the end of the 4.4 merge window. This second platform-drivers-x86 update has "support for the unfortunately rather unique ESC key on the Ideapad Yoga 3" plus fixes and DMI list additions.

The ideapad-laptop driver had to be patched for the Linux 4.4 kernel in order to support the Yoga 3 escape key. Unfortunately, it's a mess supporting the ESC key on the Yoga 3 under Linux while on Windows there is a "Windows Paper Display driver" to provide this functionality due to how Lenovo weirdly maps some of the keys. Those interested in details on this ESC key situation can see this patch message.

The other latest x86 platform driver updates can be found via this pull request.
