It's too simple just to intersperse the new and delete the unneeded at any point in a traditional email client.

Grub's non-default selections usually limit Xorg's ability to function.

Is the failure the same after removing the nouveau driver package to enable the integrated driver and restarting? Note that Debian and Fedora 6 months ago or longer made the integrated modesetting driver the default for most non-antique gfxchips. Other distros have at least acknowledged that FOSS driver development has been heavily focused on minimizing the need for gfxchip-specific drivers. >> Do either 'dmesg | grep fail' or 'systemctl | grep fail' provide clues? > Yes, both fail to provide clues.

TDE cannot use a screen that xrandr cannot find. Thus, querying a forum with more CentOS and/or recent video hardware users is more likely to get needed results. Something else to think about: boot a live disk of something recent enough that it surely should support M2000 out of the box. https://wiki.trinitydesktop.org/LiveCDs -- "The wise are known for their understanding, and pleasant words are persuasive."
