monitor problem on 19" Hannstar AH191D Widescreen Multimedia Monitor
All right i just installed Linux Ubuntu and my monitor (19" Hannstar AH191D Widescreen Multimedia Monitor) just won't work properly it comes up with distortions ( black lines and dots)One is wide enough to see that it contains display material from the right of the screen, and this line is near the left. I tried changing the driver settings but there was no driver realsed for this type of monitor so i tried entering them manually still the same problem remains. Here:

login in a console mode and do a xorgconfig. and find out your monitors range and default resolution
Check the /etc/X11/xorg.conf and /var/log/Xorg.0.log to see what driver you are using for the Graphics card and anything else you can determine about it.
How do i check it i am a Linux noob
Use any editor to open the file: /etc/X11/xorg.conf
Or--in a terminal--enter: "more /etc/X11/xorg.conf" (no quotes) Use the spacebar to scroll down. Look for sections similar to what is shown below and post what you find.
These are edited heavily to illustrate what you are looking for:
I don't know what might be the issues with "sis" driver, but Google will surely have something (I peeked).
Things to try:
Comment out the line starting with "Virtual" (just add "#" --no quotes-- at the beginning) What this does is put the desktop into a space larger than the screen---very confusing (to me) turn it back on later to see if you like it
For readability if nothing else, delete all the modelines except the one for 1440x900@60 and maybe 1440x900@75 . Likewise, delete all the modes except the two for 1440x900.
(LCDs always want to be at their native resolution and most are not useful above 60Hz---I'm sitting here on one running at 50 and there is no hint of flicker.)
To edit xorg.conf, you will need to use "su" to become root (or maybe sudo). Then you can use any editor--eg gedit, kedit, nano,
It's a good idea to make a copy of the file before changing it.
cp xorg.conf xorg.conf.copy
as i said before i am only an armature at using Linux and find your solution a bit hard to understand, please note that i have also adjusted my screen to 1280x720 @ 60hz as i found the default monitor settings 1440x900 @60hz too bad (too much distortions) Anyway i appreciate your help and if possible provide a more detailed guide to the possible solution.
1280x720 is a 16:9 aspect ratio. Your monitor has a native resolution of 1440x900, which is 16:10. 1280x720 is the one I would expect to show distortion.
Again, I can't speak to the choice of video card or driver.
As for editing xorg.conf, which part of the instructions did you not understand? Please don't hesitate to ask the most basic questions---we're here to help.
One thing that can be intimidating is the terminal and the various commands. In the long run, there is a high payoff for learning a few basics.
press the alt F1 you will see a menu pop up if not press the windows button. Yes the one on you keyboard that looks like windows that could also bring up your menu. go to system admin there you will see the screen resolution click on it and then change your resolution all will be well. if not if you hold you mouse at the edge your screen will move with it. you may be able to open a terminal then type display and type xorg then push the tab button you will then get some comamands for xorg. if you get xorgcfg use it if you get xorgsetup that is better if you get xorgconfig you better know what your doing.
