Kernel-based mode-setting, or KMS, allows an improvement on the display of a Linux server. In the case of a remote dedicated server, these benefits will be difficult to exploit. We recommend disabling this feature which is enabled by default for the 'new' driver. 

===How to find out if the KMS is activated== =

Using this command, if the result is not '0' : 

cat /sys/module/nouveau/parameters/modeset
-1

==How to disable the KMS== =
  • Set modeset to 0 in the default grub settings /etc/default/grub (to be added at GRUB_CMDLINE_LINUX):
nouveau.modeset=0
  • Regenerate the grub configuration files to reflect the default settings:
grub-mkconfig -o /boot/grub/grub.cfg
  • Check that the option is set up correctly:
grep -ri nouveau /boot/grub/
  • A restart is necessary to take it into account. Si les commandes précédentes ont générées des erreurs, il est indispensable de vérifier avant de procéder au redémarrage.
