Last week, when my system froze, I was able to use SysRq¹ key combinations to sync disks, remount and reboot. Might be a good idea to check if it is enabled² (it should be enabled by default AFAICR), and keep instructions handy, if your system will freeze once again.Hmm, this combination is new to me. As I am using plasma5, there is <ctl><alt><escape>, which changes the mousepointer to a skull. Clicking then with the skull on some window, it will kill this window/ application. However, this does not work.Pressing <ctrl><alt><F1> should switch to console 1, (F2 to 2, F3 to 3 and soon) but this does not work, too. As I said, completely frozen! Oh, and it is also not possible, to login from another computer (i.e. with ssh), as due to the freeze authentication and other things do not work then.
