Comment 2 for bug 1496151

Do you have a chance to try a current Ubuntu life session on this machine, like 15.10 beta? http://releases.ubuntu.com/wily/

If this still happens there, please install the "evtest" package, run "sudo evtest", select they keyboard, press the Alt/Shift/etc. keys, then press Control-C, and copy&paste the output. Please annotate the output with which keys you actually pressed for which part of the output. Thank you!
