I'm having real trouble changing my screen resolution. When I go into the monitor settings the only choice is 1920 x 1080. Now, I had the exact same issue when using this monitor (it's actually an HDTV) with Windows and had to change the resolution in the nvidia settings manager to resolve this (turns out the correct resolution for this screen is 1842 x 1026).
I've looked through the forum, and found a possible solution involving creating a file called config.txt in the boot folder, but Fedora isn't letting me create this file (access denied), and when I try to run "sudo openbox" in terminal it tells me that my user (the only one on the system) is not on the list of sudoers, and that the incident has been reported :S
Going through dmesg (type dmesg|more), I noticed in the kernel command line two parameters bcm2708_fb.fbwidth=720 and bcm2708_fb.fbheight=576, so I added them to the file /boot/cmdline.txt, with the values I needed; it worked.
It seems fedora isn't using the file config.txt, unfortunately, since I don't know what are the kernel parameters for other config.txt options.
As for sudo, you may login as root, and also I think under X the regular user is prompted for the root password for administrative actions. Don't know if there is some way to start a file manager window as root, for instance.
Since ssh was working without any tweaking required, I just use ssh -X root@raspi in my laptop, and then launch gedit (runs on the raspi, but displays in my laptop's X session). This avoids the problem of misconfigured display, while allowing the use of graphical environment.
