 Posted: Thu Nov 10, 2011 7:43 am Post subject: Setting proper screen resolution in X |
 |
|
Ever since I switched from an Nvidia card to a ATI card I cannot seem to set my screen resolution to 1440x900 with a 75Hz refresh rate. With my old Nvidia card doing this was easy using Nvidia settings. I have yet to figure this out with my new card.
Here is my xorg.conf

| can you explain how you got your screen set that way? Do you have a xorg.conf that you can share? Your post doesn't help much. |

I do not use this resolution as seen from the output of xrandr.
The use of the asterisk.
The rest is allowed.
LVDS: my laptop display.
CRT1: my Samsung SyncMaster E1920 LCD monitor.
xrandr what to say you? |

Your config file seems to have some unecessary lines.
Here's my (complete!) working xorg conf for three monitor setup, but I use open drivers - don't know if it will work with proprietary drivers (the open ones are great, though)
| Code: |
Section "Monitor"
Identifier "NEC P221W"
Option "PreferredMode" "1680x1050"
EndSection
Section "Monitor"
Identifier "Eizo L568-1"
Option "PreferredMode" "1280x1024"
Option "LeftOf" "NEC P221W"
EndSection
Section "Monitor"
Identifier "Eizo L568-2"
Option "PreferredMode" "1280x1024"
Option "RightOf" "NEC P221W"
EndSection
Section "Device"

Driver "radeon"
Option "Monitor-DVI-1" "NEC P221W"

| most of that was put there by aticonfig so I'm not sure if that stuff has a purpose but with out this xorg.conf file I can't get X to start. I'm guessing yours doesn't because you are using the open source drivers. |

OK bumping this thread after a month of inactivity as I have still not figured out how to fix this. I am not running ati-drivers-11.11

What is weird about this output is that it states that my setup allows for a maximum resolution of 1600x1600 yet 1440x900 is not an available option. Does anyone know if there is a way to force my resolution to 1440x900? |
