Ubuntu hangs on the startup screen.
Ubuntu hangs on the startup screen.
I powered down my machine last night. This morning it refuses to start and stays on the Ubuntu splash screen. I can access recovery mode, so I think I can recover from this. I’m using Ubuntu 18.04.3 Graphics llvmpipe (Lomb 9.0.1, 128 bits). The PCPartPicker Part List shows several items including a CPU, cooler, motherboard, RAM, storage, and a monitor. My build is complete; I installed Vulkan and thought some updates might have caused the issue. I’m unsure if that’s connected. The problem seems to appear when the system hangs at the Started User Manager for UID 121, though it says OK in the brackets to the left.
You might be able to dive into the system and undo the most recent change, though it seems to resemble a poorly applied GPU driver fix—but there could be other reasons as well. Record the packages you restore to help identify what might have triggered this issue.
You could ask for clarification or explain your question more clearly.
Begin the computer in CLI mode first. As I recall, you need to press CTRL + ALT + F1 or F2 to view the logs and monitor activity.
I recommend going back to the earlier driver version via recovery mode, as discussed previously.
Great news. I realized it might have been an incorrect update. When I accessed the recovery manager, I noticed around 49 packages requiring updates. I chose to proceed and it paid off. This seems to be the result of using a longer-term version with updated hardware.
Start the system from the installation disk, launch a terminal and adhere to the provided instructions. Adjust the installed packages from before your most recent reboot. This should resolve the issue—looks like it’s fixed!
That's the situation. It seems I'm sticking with the LTS release of Ubutnu. The Radeon 5700 is a more recent GPU, but the kernel bundled with LTS doesn't support it, so I had to upgrade my kernel. In practice, people usually prefer the newest versions for newer hardware. I believe the next Ubuntu release is coming around April, and it's expected to include an updated kernel based on what I've seen. From what I know, Ubuntu has generally performed better than Windows 10 for me.
