If so then you are running into problems with the newer Linux kernel. > My keyboard and mouse are Logitech. > > Nota : I have the same issue with the Ubuntu last release (13.x) so > I guess it's a kernel issue but I have no idea of the parameter(s) > to change to resolve this.. > > It really would help if anybody has a clue on what is really going on. I don't know but in recent Linux kernels there has been a big reorganization and removal of features. Unfortunately many of us were using those features. So when we install the new kernel it causes kernel panics and other problems. One set of problems has to do with them moving firmware blobs out of the kernel. In Debian these have been moved into firmware-linux-nonfree. If booting the older kernel works then try installing firmware-linux-nonfree and see if that helps. Secondly there have been problems with the graphics subsystem. A lot of previously supported video cards lost support in recent Linux kernels. You say your keyboard is not working. Is the system still up and online and on the network? Are you able to ping the machine from another system? Are you able to log into the machine with ssh from another system? If so then you might be able to use that path to debug and fix this problem. If not then the problem is deeper than your keyboard. Good luck! Bob
