Благополучно пользовался x2go, но достали постоянные обрывы соединения, а так как соединение с той же машиной по ssh-у в консольке все это время прекрасно держится - то виновным был признан x2go. На удаленной машине - gentoo. Решил попробовать nomachine. Поставил сервер, открываю на клиенте соединение и вижу черный экран, в правом углу окошко (отрисовано явно средствами mate, стоящей на удаленной машине) с надписью
Could not connect: No such file or directory
