[SOLVED] Ubuntu 9.10 Resolution Problem

[AxlD]

My system specs are:

CPU: AMD Phenom II 965 3.4GHz Black Edtion
MoBo: ASUS Crosshair III Formula
RAM: Corsair Dominator DDR3 3X2GB 1600MHz
GPU: Sapphire Radeon Vapor-X HD 4890 2GB GDDR5
HDD1: WD 500GB Black Caviar
HDD2: WD 1TB Green Caviar
Case: CoolerMaster Haf 932 Black Case
PSU: Crosshair CMPSU-650TXEU 650W
Monitor: Samsung Syncmaster P2370

And right now I'm using Ubuntu 9.10 64bit.

Having Ubuntu 9.04, openSuSe 11.1 and Linux Mint, and after the intallation of the Ati drivers (using the Hardware Manager either the manual installation) I was not able to setup a resolution of 1920x1080 in my monitor. Also for a reason unknown to me (and everyone else I asked) when I typed in the terminal "aticonfig" or "aticonfig --initial) the response was: "aticonfig: no supported adapters detected".
Not to mention the watermark in the down-left corner of my screen saying: "AMD Not supported hardware"

I just installed Ubuntu 9.10 Karmic Koala and what is changed is that the command "aticonfig" works!!! But the command "aticonfig --initial" does NOT!!! :'( :'( :'(
Also I don't get the annoying watermark anymore.

After I installed the FGLRX driver though the Hardware Drivers section my xornf.conf looks like this:

Section "Screen"
        Identifier      "Default Screen"
        DefaultDepth    24
EndSection

Section "Module"
        Load    "glx"
EndSection

Section "Device"
        Identifier      "Default Device"
        Driver  "fglrx"
EndSection

Also I have to say that I have the same problem in Windows, only the problem is fixed when I install the Monitor Driver from Samsung. Before the installation of the monitor driver, the max reso I can have is again 1600x1200 but after that I can have 1920x1080. So I suppose that I have to force the monitor the reso I want somehow...

please, PLEASE, help deal with this really frustrating problem. Excuse my english and thank you in advance...

Edit Monitor and Screen sections. If there isn't any Monitor section then create it :

Section "Monitor"
	Identifier	"Generic Monitor"
	HorizSync	30 - 71
	VertRefresh	50 - 160
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Device		"Configured Video Device"
	Monitor		"Generic Monitor"
	DefaultDepth	24
	SubSection "Display"
		Depth		24
		Modes		"1920x1080" 1600x1200" "1280x1024" 
	EndSubSection
EndSection

I have posted Generic HorizSync and VertRefresh rates. Check your Monitor's Manual for supported Refresh rates.

devils casper thank you for the quick response. I applied the changes as instructed, placed the correct HorizSync and VertRefresh but after the reboot instead of being in the GUI, the command line opens up asking for logging. I log in but I cannot open up the GUI. I remeber that a I have to press Alt+F7 or Alt+F8 but nothing happens. What am I supposed to do? I don't mind reinstall cause I have no programs yet installed. The first priority is to fix the resolution. Again thank you in advance.

Execute this

cd /etc/X11
sudo mv xorg.conf xorg.conf.bak
shutdown -r now

Above code will rename xorg.conf file and on restart, X Server will use Generic Values to load GUI.
Post the contents of /etc/X11/xorg.conf.bak file here.

Thanks for this fix, it also works to restore dual monitor functionality in Karmic Koala (9.10) on a Dell d610 with an Intel 915M graphics controller.

Execute this

cd /etc/X11
sudo mv xorg.conf xorg.conf.bak
shutdown -r now

Above code will rename xorg.conf file and on restart, X Server will use Generic Values to load GUI.
