screen resolution in Fedora 13

[AshtaFelix]

Hi all,

Is there any way to change the screen resolution to something other than 1024x600, 800x600 or 640x480?? I have tried to do so both through "system preferences" and through xrandr. In system preferences, I only have the three options mentioned above. When I try through xrandr -s to change it to something like 1024x768, it yeilds:

Size 1024x786 not found in available modes

.

This is slightly infuriating for me, as some of the applications such as Evolution require a screen resolution height greater than 600. Help?

Might be worth installing the correct video driver, assuming you haven't done so yet.

Which Graphics Card do you have?

lspci | grep -i vga

Open /etc/X11/xorg.conf file or create new if there isn't any and edit it.

Section "ServerLayout"
	Identifier     "single head configuration"
	Screen      0  "Screen0" 0 0
	InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

	Identifier  "Keyboard0"

Section "Device"

	Driver      "i810"
EndSection

Section "Screen"
	Identifier "Screen0"
	Device     "Videocard0"

		Depth     24
		Modes    "1280x1024" "1024x768"
	EndSubSection
EndSection

Save file and reboot machine. You must have root privileges to edit/create xorg.conf file.

In case it doesn't work, replace Driver "i810" with "vesa" in Video Card section.

Linux can be a strange animal. Works perfectly here, on my laptop, with no human intervention.

This stuff can make one tear one's hair out.

Display unit create problem for X Server most of the time. Most of my machines don't have xorg.conf file and display works fine in all. I had to create xorg.conf file manually in a few because X Server couldn't configure Monitors correctly ( supported Refresh rates and modes).

Uh, that didn't work, now the screen is all static-y and I can't see anything. The Fedora loading screen is all fine, but once I get to the login screen, everything is so fuzzy that I can't even see the cursor! I'll just have to boot into rescue mode! Oops!

Remove Driver line from Video card section and let X Server detect correct driver.

I can't do that because I can't see anything!

I tried to download a rescue disk, but the only ones I could find were i386 and I need i686. There is no option on the Fedora 13 CD or Live USB for Rescue Mode. HELP?!
