I added only minitube. and no settings changed. on the same machine was previously the last Manjaro version installed and exhibited the exact same behavior. my guess is a kernel bug. but I am total beginner. for comparison runs Windows XP Professional x64 on same machine without any problems. an overheating problem can I exclude. under normal use the laptop is indeed warm but not hot. sensor shows a maximum of 65 ° C. what is completely in normal range.
