Mr. Takashi, follows your request for 'xev' in an IceWM session. This package was already installed. Mr.Stefan, follow your request for output 'rpm --changelog -q xorg-x11-server | head -n 10 '. I did not disable the patches mentioned, because I do not know how to do this. But I looked for them with the zypper, and it said that 'no matching item was found'
