I have the same issue on a Thinkpad X395: with power plugged in, everything boots fine. However, on battery it will only boot to a black screen once the display manager is started.
Plugging the power in, booting up and unplugging the power once the login-screen appears does work, however. Also, using `nomodeset` as kernel option works, but in that case, amdgpu won't be loaded (I assume some generic VESA driver is used in that case). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870971 Title: [amdgpu] Xubuntu 20.04 boots to black screen on Lenovo Ideapad L340-17API To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1870971/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
