I realise most people will have moved to v7 but I just had to upgrade an older ATOM based system can not run ClearOS7.

Installing ClearOS_Community-6.8.0.174473-i386.iso (32bit)

The default install includes a graphics mode GUI and I could not find any option for a minimal text mode install.

The removal of ClearConsole is documented by Clear Foundation here: https://sfj48-fkj200.heiksthsd.cf/resources/documentation/clearos/content:en_us:kb_o_removing_clearconsole

For various reasons, you may want to remove ClearConsole after the install. These reasons may include:
Increased performance. By reclaiming the resources required to run ClearConsole, you can optimize further the performance of your server. This is especially useful if ClearOS is running as a VM.
Alternate graphical state. By removing the ClearConsole, you can make way for the ClearOS Core Desktop interface.

Note the page does not include a version number for the OS so perhaps is not for v6.8

I found the provided yum remove command on that page to be too aggressive as it also removes tconsole (the text mode admin login screen) and shared-mime-info and various "libX" librararies (I didnt take detailed notes) that seem to be dependancies for other packages in 6.8.

I copied the command from the ClearFoundation page and then deleted the references to '*libX*' '*console*' and shared-mime-info (so those packages are retained on the system) and this worked well - the box then booted to the familiar red rectangle admin login.

yum remove '*x11*' GConf2 ORBit2 alsa-lib atk fontpackages-filesystem gnome-vfs2 hicolor-icon-theme hunspell jasper-libs libICE libIDL libSM liberation-fonts-common liberation-sans-fonts libfontenc libthai mesa-dri-filesystem mozilla-filesystem pixman plymouth-graphics-libs sgml-common xkeyboard-config

Posting this for 3 reasons... 1) it might help someone else, 2) to suggest the ClearFoundation documentation maybe needs a version number and 3) selfishly so I can find it again next time.
