The driver module is i915.

For adjusting screen resolution look within system --> administration/settings

Did you read what you posted? You originally said that you need the display driver....but the error here is telling you that the system doesn't know what kind of MONITOR you have. The two are different. Since you're an RHCE, have you tried looking at any of the RHEL knowledgebase docs on this? Since you're using RHEL6, you are paying for it, right???

And this has been covered before:
http://www.techotopia.com/index.php/...tiple_Monitors
http://www.linuxforums.org/forum/red...esolution.html

Run the X configuration tool to generate a new xorg.conf file, and get your monitors manual, to see what resolution it supports. You can make any modifications you wish in the xorg.conf file, up to the maximum allowed by your hardware. Max resolution for both your video card and monitor can be found in the manuals for those devices. A 'certified' RHCE should be able to easily follow/edit the xorg.conf file.

It would have seemed to me that an RHCE would already know how to fix such things. And did you get it working? Did you look up anything on the knowledgebase?

If you solved the issue, post the solution. If you haven't, post what you've tried, and leave the sarcasm out.

I have reinstalled gnome packages but of no use.

No. of people said that make changes in /etc/X11/xorg file
but I don't know what to change.
So i examine another PC, but there is no file there named xorg in /etc/X11.

and the output of my /etc/X11/xorg file is,

Section "Device"
Identifier "Videocards0'
Driver "vesa"
Endsection





Now plz tell me what to do???????

So if you still need help, why be sarcastic to those helping you?

...which will make ZERO difference, since Gnome runs on top of X, and the problem you're having is with X itself.

Right...since you're an RHCE, wasn't this covered? Did you not read/understand the articles posted before? From one of them:

Spell out your words. And again, THIS HAS LITTLE TO DO WITH YOUR VIDEO CARD...it is your MONITOR that's unknown. The VESA driver is generic, and will work at whatever resolution it can. The MONITOR is what needs to be identified. Since you posted the DEVICE section of the xorg.conf, did you try looking at the MONITOR section??? That would be the place where your MONITOR is defined. It would look like this:
Code:
Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "MFG"
    ModelName      "Model"
    HorizSync       28.0 - 33.0
    VertRefresh     43.0 - 72.0
    Option         "DPMS"
EndSection
Try reading the man pages on xorg.conf yet?
http://www.x.org/archive/X11R6.8.0/doc/xorg.conf.5.html

You have to define your monitor capabilities first; AGAIN, read the manual for your monitor to determine what it can do, put the values in. Then in the SCREEN section, you can try to define other modes, up to the limits of your video card (which AGAIN, you need to look up in the manual for it). Again, the xorg.conf man page has ALL the options/syntax in it. Read/understand it.

Did you run the "Xorg -configure" command, as suggested? Did you look at the output of the file it generated? Did you see a SCREEN section?
Code:
Section "Screen"
	Identifier	"Default Screen"
	Device		"Whatever Device in Xorg"
	Monitor		"Whatever Monitor in Xorg"
	DefaultDepth	24
	SubSection "Display"
		Depth		24
		Modes		"1600x1200" "1280x960" "1280x1024" "1024x768"
	EndSubSection
EndSection

As TB0ne pointed out, you just need to add a desired screen resolution in /etc/X11/xorg.conf file, as follow:

Code:
Section "Screen"
 Identifier     "Screen0"
 Device         "Videocard0"
 Monitor        "Monitor0"
 DefaultDepth    24
 SubSection     "Display"
 Viewport       0 0
 Depth          24
 Modes          “Add here” "1280x1024" "1280x960" "1152x864" "1024x768" "800x600" "640x480"
EndSubSection
Then once use Ctrl+shift+backspace key combination, so it will give you login prompt, and xinet service will restart automatically.

The problem has solved. I simply add these lines
Quote:
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280*960"
EndSubSection
to xorg.conf file and now my machine can support
Quote:
1280*1024
1024*768
800*600
640*480
