I can confirm the same behavior with Kubuntu 24.04 upgraded from 6.8.0-49 to 6.8.0-50. System boots to LUKS password prompt and I get 2 seconds or so to type before the screen blanks for 2 seconds. When it returns I am unable to type. Using Grub Advanced I can force the boot to 6.8.0-49 and everything works fine as before. Alternatively I can use Grub Advanced to edit the 6.8.0-50 command line and remove quiet and splash to do a text boot. In that mode I still get the flash behavior; however, I am able to continue typing after the flash. I found several Mint related posts complaining about the same kernel with the same issue.
My system is an AMD 5950X with and AMD 7800XT video card. RAM is 64GB. Keyboard and mouse are Razer and they are hard wired in. When Windows 11 people want to switch to Linux, this kind of behavior is very unsettling to them. While my experience gives me the ability to work around it, this really needs to be fixed. Its not comforting to find and 8 year old ticket that describes the same issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1621367 Title: 4.4.0-36: keyboard dead at boot & full disk encryption prompt for password To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1621367/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
