Really Unusual Xorg Problem with new monitor!

sc30317 · 2008-08-31 17:01:31

Hey all,

I just bought a Samsung Syncmaster 2493HM, which is an awesome 24" monitor that swivels 90 degrees so you can do portrait mode (like the really old imacs).

Unfortuantely, I am having problems with it in arch.

I use an ATI 4850 Video card, which worked perfectly with my old 22" monitor @ 1680x1050.

I turned off my computer, unplugged it, and plugged in the new samsung. The font was about 800x600 size; however, when I went into Catalyst 8.8 or System->Preferences->Screen Resolution, it says I am @ 1920x1200.

I have figured out that If I go to 640x480, then CTRL+ALT+BACKSPACE, I am able to change back to 1920x1200 and have the screen look 1920x1200, but this fix does not work after I log out and log back in, or restart.

I would also enjoy being able to rotate the monitor 90 degrees. I do not have the rotation option in System->Preferences->Screen Resolution.

Any help would be awesome!

Gnome's bultin Preferences -> Screen Resolution dialog is very, very weak, so I doubt it ever shows an option to rotate the screen. I don't know if ATI have their own control panel (nVidia does, and it's great BTW), try to install one.

For resolution, you should configure that in /etc/X11/Xorg.conf for keeping the resolution settings. See the Arch Wiki for more on that.

Here is my xorg.conf

Section "ServerLayout"
Identifier "aticonfig Layout"
Screen 0 "aticonfig-Screen[0]-0" 0 0
EndSection

Section "Files"
EndSection

Section "Module"
EndSection

Section "Monitor"
Identifier "aticonfig-Monitor[0]-0"
Option    "VendorName" "ATI Proprietary Driver"
Option    "ModelName" "Generic Autodetecting Monitor"
Option    "DPMS" "true"
EndSection

Section "Device"
Identifier "aticonfig-Device[0]-0"
Driver "fglrx"
Option "RandRRotation" "on"
Option "RandR" "on"
BusID "PCI:1:0:0"
EndSection

Section "Screen"
Identifier "aticonfig-Screen[0]-0"
Device "aticonfig-Device[0]-0"
Monitor "aticonfig-Monitor[0]-0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection

I have no Idea how I would change it in order to work with the resolution correctly and to be able to rotate the screen. Any helpers?

In my xorg.conf I have resolutions listed in the "Display" subsection as shown below:

SubSection     "Display"
      Depth       24
      Modes      "1440x900" "1024x768" "800x600" "640x480"
EndSubSection

You may want to try adding the resolutions you want your monitor to display. Just a guess, but it may help.

Also, have you looked over the Arch Wiki as freakcode suggested?

There are no resolutions pre-configured here, that's why you get a different resolution every time. Refer to how configure Xorg on the Wiki.
