I want to install RHEL7 in purely text-only mode. Although I added the inst.text and inst.cmdline kernel option (since I want it to install from kickstart) it still requires more than a console as it is pushing its output through the framebuffer.

Is there a way to force it to disable the framebuffer entirely and have everything visible to a plain console in text on Red Hat 7? There seems to be no nofb option.

  • Appending "text" on the install options did the trick on CentOS 7 install for me too... – user91271 Nov 12 '14 at 13:47

I was using Centos 7. On the install, I hit tab to bring up the install options, and appended "text" on them.


This is what I did. (add nomodeset)

 label CentOS 7 x86_64
   KERNEL linux/centos/7/x86_64/vmlinuz
   initrd linux/centos/7/x86_64/initrd.img
   APPEND nomodeset lang=us keymap=us noipv6 ip=dhcp ks=http://pxe.example.com/pxe/linux/centos/ks7.cfg

This is what worked for me. Please change the values as per your environment.

This is my PXE file /var/lib/tftpboot/pxelinux.cfg/default parameters :-

KERNEL distros/CentOS_7.1_64/images/pxeboot/vmlinuz
INITRD distros/CentOS_7.1_64/images/pxeboot/initrd.img
APPEND ks= ksdevice=link

Additionally, I have used cmdline in my kickstart file instead of text.


If you (like me) are using this on a server from a management module web-interface and you see everything, but can't type or move the cursor, the framebuffer is actually not the problem. This bug is and the workaround is to append usbcore.autosuspend=-1 to the kernel command line.

For some possible candidates on fixing framebuffer/video issues, there are few interesting parameters in the Installation Guide: inst.xdriver=vesa or inst.usefbx.

Apart from those there's also nomodeset, which worked for me after the installation, where I could verify there's no /dev/fb* device, which is said to be an indicator of framebuffer's presence.


press ESC on first boot screen and input "linux text" boot:linux text
