Hi! Since upgraded to xfce4.12, from 4.10, I cannot start the display settings panel and I get the "Segmentation fault (core dumped)" error when I run in terminal "xfce4-display-settings". I don't know if it's related but before upgrading to 4.12, since xrandr was introduced, I had issues with display-settings detecting my laptop screen resolution (full hd) and I had to manually add a profile that fits my normal resolution, otherwise I would have a resolution of 640x480px (this one is shown right now in my nVidia settings in "X Screen Information" section). Even after I had a working xrandr profile I couldn't see that specific resolution inside display-settings. Some general info: - asus laptop - archlinux x86_64 - kernel 3.19.2-1 - bumblebee & xf86-video-driver (hybrid graphics) What have I tried so far: 1. Create new user account - same issue. *The root account has the same problem. 2. Renaming ~/.config/xfce4/xfconf/xfce-perchannel-xml/display.xml. Logout - Login. Problem persists. This is the original file: http://pastebin.com/g1zqAF9N and this is the new created after login: http://pastebin.com/C3v4kZY9 Debug info: 1. "strace -o ~/trace.txt xfce4-display-settings". Output: http://filebin.ca/1vOGqtRiEnvS 2. gdb instructions from wiki. Output: http://pastebin.com/BVPnF3tA
[SOLVED] xrandr issue after all. Step 1: reset xrandr with "xrandr -s" Step 2: add a new xrandr mode. Step 3: use that xrandr mode. Step 4: open display settings. Notice that it works and also the added xrandr mode is listed! Probably the 4.12 upgrade couldn't detect the already added xrandr modes..
