I had this problem, too, with a PC (I'm sorry, I can't access the PC; this is from my written/saved records): CPU: AMD Ryzen 3 2200G, 4x 3.50GHz, boxed (YD2200C5FBBOX) Graphics: AMD Vega 8 Kubuntu 22.04, fully updated today
Expected: PC starts Actual: PC monitor stays black after logo of mainboard manufacturer. Attempts at fixing this: Because I had problems with startup where the addition of "nomodeset" in GRUB helped, I tried this. This time it did not help. The computer actually started - more than before - but got stuck at various stages of the boot process. The PC would not fully start with kernel 5.15.0-112-generic. I chose 5.15.0-107-generic in GRUB. 107 worked without a hitch. At the moment the workaround is simply using 5.15.0-107-generic. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2068738 Title: Kernel update 5.15.0-112 might cause severe problems with specific AMD GPUs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2068738/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
