Help with 1440x900 resolution
Hey all,
After trying out Vista via MSDN, I grew tired of it quickly, and have fallen back to Fedora. I'm using it on a file server, administrating it through cli only. But I just installed FC6 on my desktop, which was running XP. So far, its running great. Only have 512mb at the moment, but its fairly fast.
Anyway here's my problem. I am using a Radeom x300 card, and installed ATI's drivers. However, using a wide screen, I cannot get 1440x900. Right now, its at 1280x960, and the screen is stretched to hell. When I set the resolution to 1440x900, the screen gets all messed up, moving over to about a third of the screen, and looking more like 1024x768. Here is my xorg, which is kinda foreign to me:
Code:
# XFree86 4 configuration created by pyxf86config
Section "ServerLayout"
Identifier "Default Layout"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

# Multiple FontPath entries are allowed (they are concatenated together)
# By default, a font server independent of the X server is
# used to render fonts.
FontPath "unix/:7100"

Load "extmod"

Section "InputDevice"
# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
# Option "Xleds" "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:
# Option "XkbOptions" "ctrl:nocaps"
#

Hello:
I don't have an ati card, however, if you look in your /var/lob/Xorg.0.log
you should be able to see if there are any warnings or errors that may provide a clue.
You wan to have a look nearer to the ended and see what the validated modes are and if you desired settings are working?
$ cat /var/log/Xorg.0.log | grep -F EE
it should display any errors
$ cat /var/log/Xorg.0.log | grep -F WW
to display any warnings
Seve

This is what happens:

Pardon the crappy quality. The screen is is moved over slight to the right, and then all mashed together. It's like it doesn't recognize it as a widescreen.

I'm sorry, when I set xorg.conf for 1440x900 as the only mode, I restarted gnome and had a login prompt, but then after logging the screen went black and the monitor said Input not supported. As far as checking Xorg.0.log, nothing new.

I need help with this, too. I have a Viewsonic Optiquest Q19wb, which there is no option to choose this monitor, so I had to go with the generic LCD choices. Everytime I restart after choosing the 1440x900 resolution, it comes back up with the 1024x768 resolution in hardware, and settings 1152x768. I tried choosing a 1280x800 resolution, but it restarted with the 1024x768. The picture is not sharp and I can't seem to get anywhere. I used both computers, one with an ATI 9600 card and the other with an nVidia MX 4000.
I am not a tekkie, so my knowledge of searching through the files is limited. Please keep explanations geared for the "Dummies" group. Thanks----

heres a few things that might help..
When you change the settings using the gui settings manager, your xorg.conf that was originally generated is then saved to xorg.conf~ (now the backup file.) In my experience, trying to change the monitor or settings more than once after install didn't write any new data to the xorg file (your results may vary), because the backup was already created. So if the windowed system runs after a reboot, try removing, as root, sudo, su, however ya like it, the xorg.conf~ file. Then go into the text editor under apps>accessories>text editor as root and save xorg.conf as xorg.conf.backup (this will give you a failsafe backup, knowing that the display worked after a reboot). Now you should only have two files in /etc/X11/, xorg.conf and xorg.conf.backup. This should let the graphical display settings manager to make changes that will be applied.
I just got my 19" monitor working in a weird way--under settings>screen resolution, I changed the default 1440x900 to 1280x768, and kept the settings. Then went right back and changed to 1440x900 and voila, full screen (I was experiencing the same output as you were.)
hope this helps
