As to grub.cfg: I set GRUB_TIMEOUT=5 in my /etc/default/grub, but the timeout for efi was reset to 30 on every update. I didn't know that files in /etc/default/grub.d are supposed to be changed, but I now changed
if [ \$grub_platform = efi ]; then set timeout=${GRUB_RECORDFAIL_TIMEOUT:-30} if [ x\$feature_timeout_style = xy ] ; then set timeout_style=menu fi fi in /etc/grub.d/00_header to ... GRUB_RECORDFAIL_TIMEOUT:-5 ... and hope that this helps in the future. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libx11 in Ubuntu. https://bugs.launchpad.net/bugs/1929854 Title: Vital and critical configuration files get overridden by system updates without warning To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1929854/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
