Monitor screen shifted to the right

Asked by Meteor

I installed Kubuntu 6.06 two days ago and it WAS running fine until this evening. Now, the desktop and all open screens have shifted to the right leaving a black line approx. one inch wide down the entire left side. I have been unable to locate any way in the KDE menus to correct this and I have no idea what may have caused it. I'm a 'newbie' to both Kubuntu and Linux.

The most irritating part of this is the minimize, reset/restore and the 'X' buttons are not visible when the program on screen is full size. To close, I have to right click the program name in the (I believe it's called) panel at the bottom of screen and select 'Close'. This also means that the scroll bars are not visible so scrolling through a file is impossible.

This email is being written in Thunderbird and it, fortunately, loaded in a small size. I used the mouse to stretch this page to the right (not to the edge of the screen) and to the bottom.

Monitor is a Viewsonic CRT 19 inch about two years +/- old, set for a resolution of something like 1280 X 860 (if memory serves correctly). Kubuntu was downloaded from the Kubuntu web site using a Canadian mirror.

Computer is AMD, current to 2006. Additions downloaded using Kubuntu's downloader (add/remove on the "K" icon) were the Gimp, Scribus, Firefox and Thunderbird, all of which seem to run OK (though I've never used Gimp and Scribus before so I guess they run OK...).

The black left side is not accessible to the mouse.

What's happened and how can I correct this?

I appreciate your advice.

Meteor
Canada, eh!

I also have observed this. I run Gnome. The black stripe seems to be about half an icon in width. I do not see this in the usplash screen. If you reset the screen resolution to some lower value and then return it to the right resolution, the screen is displayed properly from then on. This seems to be a bug in Xorg as I've seen it in other distros such as fedora 5 and suse 10.1. This is the first report I've seen from a KDE user. I reported it as a bug in Dapper, but I haven't heard anything since.

You could use xvidtune in order to adjust it.
Martins, could you please link your bug request?

I may be misunderstanding the problem, but can't you use the monitor's own settings to shift the display to the left? It's usually available through buttons on the front or back. If that works, make sure it stays working after a restart. It could be that the frequency is just slightly skewed.

If you adjust the monitor in Linux and then reboot to XP, the monitor may need adjusting for XP, then when you reboot to Linux you'll need to adjust it again.

If you have an LCD monitor you may have an "autoset" function built into your monitor using the keys at the front of it. Which will fix the problem as long as you don't adjust it in Windows.

Monitor screen shifted to the right

Meteor,
I experienced the same problem and it's very easily fixed.
However, like Dean said, if you use the monitor's onscreen settings or buttons or knobs to adjust this, WinXP will be off to the left when you boot back to it.
My Gnome desktop screen appears to be off to the right by about maybe 10 or 12mm.
To fix it, type xvidtune into a terminal window (or however you get to a command line), I believe xvidtune is installed by default on just about all distros, if not, just install it using Synaptic Package Manager.
Then, when the somewhat ugly (hehe, it really is) xvidtune window/utility opens, simply click "Left" about 4 or 5 times (this is right below where it says "HTotal") then click on "Apply" to see if it moved enough (you can also click "Wider" or Narrower" here to really fine tune it)
Remember to click "Apply" after every adjustment.
This will fix you up, no doubt about it... ;)

Oops!
I left out a MAJOR step in my instructions above.
If you follow the instructions above, it will fix the problem, BUT NOT PERMANENTLY. As soon as you reboot, the problem will come back.
To make the fix permanent, as soon as you get it fixed up like you like it in xvidtune, click the "Show" button.
At the command prompt that you started xvidtune from, it will now show something like this:

Vendor: , Model:
Num hsync: 1, Num vsync: 1
hsync range 0: 30.00 - 70.00
vsync range 0: 50.00 - 160.00
"1024x768" 94.50 1024 1084 1180 1364 768 769 772 808 +hsync +vsync

The line that starts with "1024x768" (and it's all one line, it just wrapped here) is the one you want.

At the prompt type: sudo gedit /etc/X11/xorg.conf

When the file opens in gedit, click on 'File" then "Save As" and save a backup named "xorg.conf.bak" or something like that.

Then, scroll down to the section that says "Section "Monitor"". It will probably look something like this :

Section "Monitor"
 Identifier "Generic Monitor"
 Option "DPMS"

Now, all you have to do is add a modeline line with your info so that it now looks like this:

Section "Monitor"
 Identifier "Generic Monitor"
 Option "DPMS"
        Modeline "1024x768" 94.50 1024 1084 1180 1364 768 769 772 808 +hsync +vsync

Again, the line that begins with "Modeline" is all one line, (in other words, it starts with "Modeline and ends with "+vsync"...all on one line, it just wrapped here)

THEN, click on "File", then "Save As" and make sure the file you are saving is named "xorg.conf". Overwrite the old one if it asks.

Last but not least. type: sudo dpkg-reconfigure -phigh xserver-xorg at the command line to update the xorg.conf with your changes and you're done!

That's it!
Hope that helps you out,
Hugh Abernathy

Had the same problem and have used the adjust buttons on the monitor. Then went to system. preferences. desktop effects and the program downloaded a restricted driver manager which seems to have fixed the alignment.
