I've got the same problems (see Bug 1173857). Sorry for my ignorance, but how do I change the theme from oxygen to something else?
I just did some testing to se what causes emacs23 to hang: - If I start emacs from a terminal, then it most of the time does to open a new window. - emacs -nw from a terminal works fine (as also noticed above) - If I start emacs from the kubuntu menu, then it (almost) always starts, and does not hang immiately. After that there are many things that I can do before Emacs hangs, such as: - compose an E-mail message (using M-X mail). It hangs only when I try to send the mail (using Ctl-C). - Write some text in the scratch-window, and save it to the disk. - I can edit some more, and do a "recover file" to get back what I saved earlier, and it still works fine. - Many of the the help menues under Ctl-H work fine. However, Ctl-H r makes it hang. After that I have to wait some time before it again starts properly. - The window splitting commands work fine. However, there are certain commands that always make Emacs hang: - Find file (Ctl-X Ctl-F) - Visit File (Ctl-X Ctl-V) - Dired - Sending of Mail - Ctl-H r (Display the Emacs manual in Info mode.) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gtk2-engines-oxygen in Ubuntu. https://bugs.launchpad.net/bugs/1142213 Title: emacs23/24 GUI does not start when run in Kubuntu 13.04 with oxygen- gtk theme enabled Status in “emacs23” package in Ubuntu: Confirmed Status in “emacs24” package in Ubuntu: Confirmed Status in “gtk2-engines-oxygen” package in Ubuntu: Confirmed Status in “oxygen-gtk3” package in Ubuntu: Confirmed Bug description: If I try to run emacs23 in Kubuntu 13.04, (KDE 4.10.0) I am finding that the GUI starts only some of the time. If the GUI doesn't start then I will only see a process running in htop or similar. Starting emacs in a terminal window with the -nw argument or installing the Lucid interface shows that emacs does run each time it starts so the problem is either with the emacs GTK interface or the GTK libraries. Emacs24 exhibits the same problem.
