Video Card Problems.

Asked by DChampnoise

I just updated to 7.04 and I am still having the same problem as I did when I had 6.06. My Video card displays on my monitor when I boot up and log in an error saying that the signal timing needs changing. Here is one of the errors I get H: 80.0khz V: 75.0khz. I am wondering if I have the wrong video drivers installed. I Visiontek XTASY 256MB card that is based upon ATI Radeon 9600.

Judging by the erorr, this is most likey a problem with your monitor, not your video card. In fact, it's not really a "problem" with your monitor, simply a case of Xorg trying to use a frequency that is out of the range of your monitor. You are trying to use 80khz horizontal frequency and 75 vertical. One or both of those numbers is probably too large. Find the manual for your specific monitor (online or offline), and see what its limitations are. Then go to your xorg.conf file and change the monitor's options to something within those settings. This should fix everything.

Good luck =)

No that didn't solve the problem. I found the PDF manual on my monitor and tried different resolutions. And it still came up with the errors. I looked at my xorg.conf file and here is what is says for my monitor.
Section "Monitor"
 Identifier "Microtek"
 Option "DPMS"
EndSection

Section "Screen"
 Identifier "Default Screen"

I still don't know what to do.

No, I'm not talking about resolutions, I'm talking about refresh rates. Those things measured in khz, not pixels. Your "Monitor" section, judging by what you posted, does not set those, so XOrg tries to guess a safe default, and fails, hence your error message. You need to check your monitor manual for frequencies. Basically check for "Hz".

If you want, upload the monitor's manual in .pdf form online somewhere, and I'll look at it and figure out what your Monitor section should say. :)

VESA 640 x 480 @ 72HZ
VESA 640 x 480 @75HZ
VESA 800 x 600 @ 56HZ
VESA 800 x 600 @ 60HZ
VESA 800 x 600 @ 72HZ
VESA 800 x 600 @ 75HZ

Okay, good :) Try adding the following line in your monitor section:

HorizSync 75.0

And then reboot. Let me know if that works (or at least changes the error message you get)

Putting that line into the xorg.conf file didn't fix the problem. After rebooting, I had no log in screen but was able to log in. I had only 2 choices for Screen Resolutions and still had the errors.

Try entering the lines in this format (DO NOT use these values or you might fry your monitor):

Section "Monitor"
 Identifier "Generic Monitor"
 Option "DPMS"
 HorizSync 25-94
 VertRefresh 50-160
EndSection

Use the minimum and maximum values supplied by your monitor manual.

I inputed the above section into my xorg.conf and when I rebooted, my X server wouldn't start. I had to nano the file and change the Generic Monitor to Microtek. Still had error.

Did you try without any xorg.conf at all? Did you upgrade to Ubuntu 7.10?

hello again
you can manually reconfigure your X server with the command:

dpkg-reconfigure xserver-xorg

And if you do not want to answer all the questions but only those which are rated with high priority:

dpkg-reconfigure -phigh xserver-xorg

Have been using Gutsy since November. For the first three months, I had no display problems, but since early February, I periodically get a problem at start up, whereby the image on my monitor appears squashed, and the fonts are the wrong size. I can resolve it temporarily by logging out then logging back in, but the problem always reappears at a later boot. During the boot process, my monitor usually loses the brown screen for a few seconds, then regains it. Sometimes it loses it completely, and I have to hit any key to restore it. I am using an ATI Radeon 9200 video card. I have not made any system modifications. Thanks for any help.

Mark, please open a new ticket since your problem is slightly different.

Can you help with this problem?
