Собственно сабж. При попытке смержить nvidia-settings вылезает следующее
* This package will overwrite one or more files that may belong to other * packages (see list below). You can use a command such as `portageq * owners / <filename>` to identify the installed package that owns a * file. If portageq reports that only one package owns a file then do * NOT file a bug report. A bug report is only useful if it identifies at * least two or more packages that are known to install the same file(s). * If a collision occurs and you can not explain where the file came from * then you should simply ignore the collision since there is not enough * information to determine if a real problem exists. Please do NOT file * a bug report at http://bugs.gentoo.org unless you report exactly which * two packages install the same file(s). See * http://wiki.gentoo.org/wiki/Knowledge_Base:Blockers for tips on how to * solve the problem. And once again, please do NOT file a bug report * unless you have completely understood the above message. * * Detected file collision(s): * * /usr/lib/libnvidia-gtk2.so.355.11 * * Searching all installed packages for file collisions... * * Press Ctrl-C to Stop * * x11-drivers/nvidia-drivers-355.11-r2:0::gentoo * /usr/lib64/libnvidia-gtk2.so.355.11 * * Package 'media-video/nvidia-settings-355.11' NOT merged due to file * collisions. If necessary, refer to your elog messages for the whole * content of the above message.
