I'm with the same problem when I try to edit grub config file. So searched over another places and found this:
"If I recall correctly from a previous discussion about this sort of thing, the problem is that when you su to root a lot of your environment which is required for the correct running of Gnome GUI apps is not set up appropriately. The consensus from the developers seemed to be that running GUIs as root was generally a bad idea and should not be encouraged. Perhaps an alternative (nano?) or just use vi." http://forums.fedoraforum.org/showthread.php?t=303374 If I've understood right I've to switch to another editor. So I'll try the same line in terminal switching "gedit" for "nano". I've switched to "sudo nano gedit /boot/grub/grub.cfg" and sucess until now. I've to reboot and see if grub is now with the new settings ready to go. So, good luck to you'll all and I'll be back, if my note don't explode. :D -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gedit in Ubuntu. https://bugs.launchpad.net/bugs/1575484 Title: "Set document metadata failed" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gedit/+bug/1575484/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
