I have installed fedora 31 from scratch with disk encryption enabled and default disk partitioning. At the time of installation the kernel version was 5.3.*. At that time the fedora was asking me to enter disk encryption passphrase with GUI dialog.
When I updated fedora, it installed kernel version 5.5.7. After reboot, the encryption passphrase prompt comes in text mode.
How can I enable the GUI for encryption passphrase again. How can I troubleshoot it?
Note: The encryption passphrase comes in text mode. After that the login GUI is shown and fedora is working properly. Even updating the kernel several times afterwards the encryption passphrase prompt is in text mode.
I have not proprietary drivers installed and graphics card is AMD. The laptop is 6 years old now, so no driver issues from long time.
So also the boot screen is in text mode, right?
After entering passphrase the the splash GUI boot screen comes. Only passphrase dialog comes in text mode.
# ?
cat /proc/cmdline
Result of “cat /proc/cmdline”:
BOOT_IMAGE=(hd0,gpt2)/vmlinuz-5.5.8-200.fc31.x86_64 root=/dev/mapper/fedora_localhost–live-root ro resume=/dev/mapper/fedora_localhost–live-swap rd.lvm.lv=fedora_localhost-live/root rd.luks.uuid=luks-cc1ba45c-e62e-44ab-ac92-0921eaf761cc rd.lvm.lv=fedora_localhost-live/swap rhgb quiet
Note: I have not changed any default boot parameters.
# possibly it can be solved by reinstallation?
dnf upgrade
dnf reinstall `dnf list --installed`
After reinstalling complete system, the problem did not solve. Still getting text based prompt for passphrase.
After updating the system today, the issue got resolved. Thanks all for your suggestions and help.
