Hi all! Just to give you a bit of a background, I've used various distros of Linux in the past 5 years or so but I still would consider myself a Newbie as I've never played around too much with it.

Here's my problem. I've recently bought a new computer and when I install Suse 9.2 x64 I get a error on my monitor when booting saying "Out of Range". Of course at that point, I can't do anything. I've tried Mandrake 10.2 and get the same error message when it's trying to load the GUI. I thought this might be because of incorrect refresh rates but both Suse and Mandrake detect my monitor and video card properly (NED LCD1712/ATI AIW x600 Pro). I've double checked in my monitor's manual for the refresh rates and both distros are putting the correct settings.

It's strange, I'm able to install in Graphical Mode. Picture looks fine.

What could be causing this "Out of Range" and how can I fix this?

Thanks for the help :D

try using a lower resolution and refresh rate than you are currently trying.

thanks for the reply, although that didn't fix it.

so for anybody interested, here's what i ended up doing (which fixed the issue).

So while it was booting, everything loaded fine but when it got the loading gui, I got "Out of range" showing on my LCD monitor. There's nothing I could do at that point. So I booted adding "init 3" as a parameter. It booted to command line. Once there, I ran "xorgconfig". Where it asked me basic questions about my monitor's specs (refresh rates...) and video card options. All seemed ok, but I got the same error after that. What I ended up doing was to edit xorg.conf (vi /etc/X11/xorg.conf) and changing the device driver of my video card to "vesa". Bam! It works now.

I'm not sure if I really understand how the videocard driver was putting the monitor "Out of range". But anyway, seems to work fine now! :D

If you post your xorg.conf file, I'd be willing to be that the source of the trouble can be identified. -- J.W.

Welcome back to LQ!

when your monitor says out of sync does it also list the Horizontal and Vertical Sync Ranges? because that's what my monitor does and if that's the case all you have to do is use the X Configurator , say you have a cuztom monitor and type in those ranges manually. the problem could also be that it's detecting the wrong chipset/video card (i'm having this problem currently). if this were the case i have no idea what the solution would be. but try the first suggestion. it might work.

ps. if your monitor won't tell you its sync ranges just go online and search for its sepcifications.

Thanks for the welcome :) This is part my xorg.conf file. Originally, under the section "Device", the driver was showing as "ati". I just changed it to "vesa" instead and that alone fixed the problem.

My monitor did not display the sync ranges. I just got a green square on the monitor saying "Out of range". It looks to have detected the monitor and video card properly, although I did have to change the driver to "vesa" instead of "ati".

I think the problem is that your horizontal and vertical refresh rates are not set correctly. Your file shows them set to Horiz = 30-81, Vert = 43-76, however according to
this source the correct settings should be Horiz = 31.5-81, Vert = 56-75.

However, before you go changing anything, note that using incorrect video settings may potentially damage your monitor, and therefore, you must personally verify the correct settings for your monitor. If you have the owner's manual, they should be listed, otherwise please confirm to your own satisfaction that any new settings are safe. If/when you are comfortable proceeding, just edit xorg.conf then restart X. Good luck with it -- J.W.
