I recently updated (after maybe a week lapse) and now I cannot start emacs (at least, this is the only application I’ve noticed so far). Here’s what I see:
$ emacs emacs: symbol lookup error: /usr/lib/libxcb-shm.so.0: undefined symbol: xcb_send_request_with_fds
It seems that libxcb-shm is a shared memory library for X11.
I also tried
emacs -Q and
emacs -nx, but neither changed anything, nor did completely removing emacs and reinstalling.
I’m running a fairly fresh install with Gnome. The only major changes are these: I replaced lightdm with gdm, and tried to get bumblebee working (i think it was, but I removed it anyway). I’m using the nvidia drivers and running wayland. Generally things seem to be working well, except for emacs.
Where else can I look for debugging?
