Dual monitor configuration problem in Redhat linux


Hi all

one monitor is working fine but the display is not coming on other monitor. I guess no problem in monitor because i swapped the cable to check the individual monitor. When i try to install the new driver its giving GCC-VERSION-CHECK while installing.

And i do not think i have to install the new driver because it has already one. What should i do to configure the dual monitor. Do i have to edit any configuration file.

My system configuration details are below. Thanks in advance for your kind help.

Redhat version : Redhat Enterprise Linux WS release 3 (Taroon update 4)
Driver in SRBC 26: NVIDIA-LINUX-x86_64-1.0-7664-pkg2.run
Nvidia card model : Quadro fx p171
Bios version of Nvidia : 4.35.20.23.07
p/n : 900-50171-0400-0000K
600-50171-0002-201J

Your RHEL version is old...I'd update it. Since you're using RHEL, you've got an upgrade path available, so contact RedHat support and they can assist you with it.

Using the current nVidia driver would be a good thing, also, but not required. You have two options: nVidia's twinview or Xinerama. You don't say what desktop environment you're using, but there are usually options in your configuration utilities to enable dual-head video, and this has been covered on LQ before. These may help you:
http://www.linuxquestions.org/questi...5200-a-285467/
http://www.linuxquestions.org/questi...y-woes-650112/

You'll again have options. You can 'clone' the display (both monitors display the same thing), or have one desktop spread across two (xinerama). If you're using the proprietary nVidia drivers, you have a Twinview option, which is well documented in their installation instructions.

Dual display

hi TB,

when i give redhat-config-display the display didnt say anything about dual monitor configuration. when i go for advanced settings the driver option given is nv . Twinview will come once the driver is in nvidia i guess , but i dont have that option in that list . If i try to edit /etc/X11/XF86Config file, Xserver is not starting. once if i change it to nv or vesa it work for both monitor but not twin view , same screen is coming on both monitor.

Is this problem is due to old Redhat version , then why this GCC-VERSION-CHECK error is coming when i try to install the nvidia driver.

Please help me .

Well, you posted the answers to your questions when you replied.

As said, Twinview is only available with the nVidia drivers...so obviously you won't have it if you don't use them (the nv and vesa drivers). The GCC error is because you're using an old version of RedHat, with a similarly old version of GCC. Again, update it, or contact RedHat support. You should have options to upgrade your system/GCC, if you're paying for RHEL (as you should be, if you're using it).

You CAN use xinerama, as I stated before, if you follow the links as guidelines. You have to configure and set up both monitors manually, and give their relative positions to each other. There are also many other Xinerama how-to guides you can find online that may explain it better.
