When KDE's "Plasma 5" appeared with Kubuntu 15.04, I found it to be too new and have too many dysfunctions, so I reverted to Kubuntu 14.04 LTS. Now this problem. Looking at the Ubuntu 14.04 repository, I found that it contained a backported version of the kernel used in 15.04. So... Remove "meta" packages that have latest 3.13 kernel as dependencies: sudo apt-get purge linux-generic linux-signed-generic Install meta packages that pull in the latest 3.19 kernel: sudo apt-get install linux-generic-lts-vivid linux-signed-generic-lts-vivid Serial now works fine. The later kernel introduces no functional changes in (K)ubuntu 14.04 that I can discern. I presume that since it is a "backported" version of the 3.19 kernel, that its video drivers have been matched to Ubuntu 14.04's version of X.Org, and so on. Anyway, that's what works for me. I could've put a "hold" on the 3.13.0-63 kernel, but this seems a better fix. -- https://mail.python.org/mailman/listinfo/python-list
