This problem was solved a few minutes ago. I followed this bug report on Red Hat Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1043686. In there, I should do "clearing out the X resources":
1) xrdb -load /dev/null (xrdb is X server resource database utility from manpage) 2) xrdb -query 3) wish (wish is a Tk simple windowing shell application from manpage, probably invoked for testing purpose only here) 4) I should uncheck KDE System Settings -> Application Appearance -> Colors -> Options -> "Apply colors to non-KDE4 applications". Yes I use KDE, and I have not mentioned it before. I am sorry. In KDE 4.10 of mine, I don't need to relogin. Now gitk runs well again. ** Bug watch added: Red Hat Bugzilla #1043686 https://bugzilla.redhat.com/show_bug.cgi?id=1043686 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1357863 Title: gitk won't start: unknown color name To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/git-core/+bug/1357863/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
