Changing the Resolution After Install...

[Georgie-o]

I just installed Fedora for the first time last night (switched from Ubuntu) and I am very pleased so far. I have a question about monitor resolution. During the install it asked me to set a resolution level, which I did at some mid/high level number (1100 x 800). It appeared that I set the maximum resolution and cna't select above that now throught the Desktop > Preferences > Screen Resolution. Is there a way to change that setting to return tha full range? I seem to recall in Ubuntu that you could go into a file with an editor and change or uncomment some resolution levels? Does that sound correct or possible for this issue? If so, where and how? Thanks

First try lauching a command box (Alt-F2) and entering "system-config-display". It should be on the first tab labeled "Settings". You can pick a different resolution there. If not, you may use the other tabs to change the definition of your display if you think it's defined wrong.

You can also change the x.org.conf file manually if you prefer. First, SAVE A BACKUP, and then change your setting in the Display section to what you would like.

Goodluck,
Jeff

I did the change thorugh system-config-display and it changed the resolution however, on both the log-in and desktop it appears as though screen extended beyond the borders of the monitor. For instance on the log-in screen the "sessions" and "shutdown" buttons were most hidden below tha bottom of the screen. Adjusting the monitor manually (using the buttons on the monitor) did not help. Any other thoughts on how to get to a higher resolution?

Thanks

Post the file contents of xorg.conf. Open terminal, enter "cat /etc/X11/xorg.conf" . Not at home so hopefully I remembers the exact naming string.

Did you load the most recent NVidia driver, or are you using the one that loaded when you installed? From my recollection, I'm betting you are using the installation driver and you need to download the most recent and install folling their instructions. Very straightforward to do.

I see (2) mode references in your file and not sure if they are conflicting or not. If using original driver, download from here and re-install. It will prompt you to remove the old one and you need to do that.

Looks like no nvidia drivers installed. This may help:http://www.fedoraforum.org/forum/showthread.php?t=45378

I believe the driver "nv" is the stock loaded driver for an Nvidia board. After running the Nvidia installer, I believe it changes the driver description to "nvidia".

how do you change the resolution if when you try to boot into the gui, your monitor mode isn't supported?

[jhetrick62]

Pancakelizard,

Use a file editing program such as Gedit. Open a terminal and become root:
su "enter" and the root password and "enter"

Enter "gedit /etc/X11/xorg.conf"

This will open the xorg.conf file where you can move down to the "Monitor" section and you can manually set the settings there. I had to set my Horizontal and Vertical refresh rates manually when I first got my new LDC monitor.

Also, check out the "Screen" section and make sure that the modes aren't set too high for now. The first mode encountered will be the highest resolution attempted. If too high for your monitor, maybe this is causing a hiccup although it should move down to the next lowest on it's own, you never know.

Also, save a copy of the file to something like xorg.backup.conf so that if it gets hosed, you can restore from this backup.

Goodluck,
Jeff
