Hello forum, I have asked earlier on Linux-General. This is probably a hardware compatibility issue so here i am. Well since i added a dedicated graphics card to my setup I am now unable to run linux smoothly. I can install them but I am experiencing "Input Signal Out of Range" as i'm expecting X to came up. If i remember correctly only Porteus Mate 3.2.2, Slacko7.0 and Ubuntu 20.04.2.0 (safe graphics) live usb booted without the error. Before the upgrade i can install and operate fine on both Buster and Slackware 14.2. As of now i am stuck with windows 7 as my main driver with several linux guest oses. But i really want to switch now asap.

I am currently looking at xrandr as advised from a related thread here on LQ.

I am ready solve this but i can't without your help.

Does your VGA cable provide all 15 pins on both ends? If not, try one that does.

This spec shows your display only has VGA and DisplayPort inputs. Does your 710 have a DisplayPort output? Is your 710 new enough you can exchange it for one that does, or return it and buy something else that has a DisplayPort output? What about exchanging the display for one that has digital outputs same type as your 710. Sometimes this kind of problem will go away when not using (analog) VGA. All the different digital output types produce superior results to VGA in most cases, often very striking.

Can you boot an installed Buster and arrive at signal out of range to find Ctrl-Alt-F3 brings you to a login prompt? If yes, goto /etc/X11. Does xorg.conf exist? If yes, rename or remove it and try restarting X or rebooting.

If no, goto /etc/X11/xorg.conf.d/ if it exists. Are there any 50-*.conf files there? Are there any other *.conf files there that appear to be for graphics configuration (e.g. 25-intel.conf)? If yes, remove or rename them and try restarting X or rebooting.

Is anything blacklisted in /etc/mod*?

Either live or installed Buster, can you append video=1600x900@60 to the linu line by editing the stanza at the boot menu (Grub, Syslinux, ?) and get different answers to any of the above questions?

A script containing a simple xrandr mode and rate command at the right place in /etc/X11/Xsession.d/ might help:If not, a more evolved one that creates a new 1600x900@60 mode then applies it might work.

I don't know but I'm excited with your reply mrmazda

Yes. Confirmed. 15 pins.

No DisplayPort. DVI, HDMI and DSUB only.

I bought it online and it is a hassle returning it and the warranty is over. I'm planning to change it when I have some bucks to spend. Something with a HDMI.

I'll have get back to you later about this. Can I do this with Ubuntu or Slackware or MX-Linux? I dd'd my Debian installer with Ubuntu to test and I always have a spare usb installer dedicated for Slackware. Just a while ago I'm planning to install MX-Linux XFCE on my SSD.

You can do it with any distro, but various distros nuance their X setups, which can monkeywrench the ability to provide appropriate, or follow, help instructions. *buntu should be well enough conformed to Debian. MX might be as well. Slackware quite likely not. I don't, and won't for the foreseeable future, have any MX or Slackware to test with here.

Hello Forum, thanks for you help. I am marking this thread solved. Just installed MX Linux 19.4 x64, without the ISOOR error. Thanks again.

Wrong thread quoted, but mmazda's suggestion to rename xorg.conf worked for me, when everything was O.K. until login, so it seemed to be a problem in my home directory.
