Video Mode not Supported

HBN · 12-24-2006, 11:23 PM

Hello Everyone,
I had this problem when I changed to a new LCD monitor. The screen is black with this message "Video Mode not Supported". Briefly the Hardware and Software details are:
1. SUSE 10
2. Dell Poweredge 1430
3. Hyundai ImageQuest L705.

Now I did try to configure “xf86config” but I don't think I am doing something right here. Also, since I am new to SUSE so I don't know much about it config issues.

Help will certainly be appreciated

Mary Christmas EVERYONE

SuSE uses the xorg server, so the config file to edit is /etc/X11/xorg.conf.

Does kde or gnome start automatically? Or do you even get the error before X starts? For different console resolutions you can add a boot option "vga=<number>". 1024x768 resolution is "vga=791" seems to work the best for me.

Did you try running SaX2 to select your monitor? "sudo /sbin/sax2"

That error is most likely caused by an error in the boldface lines here:

Code:

Section "Monitor"
  Option       "CalcAlgorithm" "XServerPool"
  DisplaySize  332 207
  HorizSync    32-48
  Identifier   "Monitor[0]"
  ModelName    "ZV5000"
  Option       "DPMS"
  VendorName   "HP"
  VertRefresh  50-70
  UseModes     "Modes[0]"
EndSection

Another thing you can try is to generate your own modeline with the gtf program:
gtf 1024 768 60 -x

Remove the ".00" part at the end of the line and add it to the "Monitor" section. Then add "1024x768_60" entries to the "Screen" -> "Modes" lines as in:

Code:

Section "Screen"
  DefaultDepth 24
  SubSection "Display"
    Depth      15
    Modes "1280x768_60" "1024x768" "1280x600" "1024x600" "800x600" "768x576" "640x480"
  EndSubSection

I am having the same problem again but with a different machine. The situation is as under.
I installed SUSE 10.1 on an OLD IBM server. Everything went well for the installation but when it came to starting off with xserver I can’t get through.
The Hardware/Software description is
1. SUSE 10.1
2. IBM Netfinity Server.
3. Hyundai LCD Monitor.

This might be due to monitor configurations but I can't figure that out. I did try "sax2" after logging as root in failsafe mode but nothing happens after that except that I get the message “Video Mode not supported”.

Help/support will be appreciated

You have had approx. 6 month to study how xorg.conf works and you still don't know

But OK

Edit xorg.conf and modify/add the HorizSync and VertRefresh in the monitor section (example in post #2). These values should match the specs of your monitor (which you can find in the user manual). As you did not give the exact model, I can't tell you what it must by.

Find the default depth in the beginning of the screen section; it's usually 24. Next look for the subsection display with that depth and check the Modeline. Only put resolutions there that you want to use and that are supported by your monitor.

If you still have problems, come back with the following info:
make/model of videocard (probably an integrated one)
make/model of monitor
sections device, monitor and screen of xorg.conf

PS I don't have experience with Suse, but I have understood that 10.1 is a bit buggy. You might want to consider to use another version.
