Red Hat Bugzilla – Bug 1264265
Enter key does not work on Grub console if keymap is changed
Last modified: 2017-02-28 04:49:12 EST
I have grub2-2.02-0.23.fc23.x86_64
1. Install ckbcomp which is called by grub2-kbdcomp internally.
# dnf install console-setup
# rpm -q console-setup
2. Create jp keyboard.
# mkdir /boot/grub2/layouts
# grub2-kbdcomp -o /boot/grub2/layouts/jp.gkb jp
Unknown keyboard scan code 0x54
Unknown keyboard scan code 0x65
Unknown keyboard scan code 0x7f
3. Modify grub.cfg to enable jp keymap.
# diff -urNp /etc/default/grub.orig /etc/default/grub
@@ -3,5 +3,6 @@ GRUB_DISTRIBUTOR="$(sed 's, release .*$,
# cat /boot/grub2/custom.cfg
# grub2-mkconfig -o /boot/grub2/grub.cfg
4. Enter 'e' to edit boot parameters in Grub console.
5. Append ' vga=ask 3' in vmlinuz boot line and press Ctrl+x to boot Fedora.
linux16 /boot/vmlinuz-4.2.0-300.fc23.x86_64 ... LANG=ja_JP.UTF-8 vga=ask 3
3. Try to press Enter key on VGA asking screen:
Press <ENTER> to see video modes available, <SPACE> to continue, or wait for 30 seconds
I cannot input Enter key.
This problem does not happen if I don't change the keymap.
If typing is changed to capital after '=' is typed, Shift+~ can revert it.
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 23 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle.
Changing version to '26'.
