I have been running 17.2 Core just fine on my Lenovo P1 Gen 7. It's been working beautifully. I was using it on a recent trip and a notification popped up about updates. I waited until I got home to run them and upon rebooting, I get a blank screen with the cursor in the lower right corner. No response to input or mouse movement. The fan just runs and nothing seems to be happening. Is there a way to uninstall the updates? Wondering if it could be the nvidia update since I have an ADA1000 card? I'm new at this but have been enjoying the journey so far. Just need some help and guidance on this one.
If it was a kernel update that has messed you up,
can you boot to grub menu,
select "Additional Options for Zorin"
select an older kernel generic version to boot.
My old acer unit has issues with the 550-560 drivers. Blinking cursor during boot, black screens after suspend. The only one that works these days is a beta driver that got released last week by nvidia (565 driver).
As stated above first try that, if that did not work i would try to look at the nvidia drivers.
Thank you for the suggestions. This laptop is not dual boot, Zorin is the only OS installed. When accessing grub, I just get a grub prompt, no options to choose from. I think the kernel is fine as I installed 17.2 from scratch and it was running perfectly fine. I believe it comes with the newer kernel. Wayland was the default desktop and whatever nvidia driver was installed out of the box was working great (I'm thinking it may have been 550). I noticed that there were some nvidia updates along with other system updates I installed and that some nvidia drivers have caused issues for others which is why I suspect that may be the issue. I just don't know how to roll back to what I had and I can't get to the desktop.
I am sure there is a simple way to get from grub prompt to grub menu and select older kernel, but I cannot find it right now. Maybe other members will know it.
That’s really annoying! I’ve had a similar issue before after an update. I would recommend trying to boot into safe mode; it’s a lifesaver for stuff like this. Once you’re in safe mode, you can uninstall the recent updates, and if it’s the NVIDIA update causing the problem, that should fix it. If that doesn’t work, you might want to look into restoring your system to an earlier point.
Thanks everyone for the suggestions. I was finally able to get it to boot using an option that had one version older kernel. After installing a couple of updates, I tried rebooting and using the newer kernel and it worked. Glad to have it up and running again. The only issue now is every time I start the computer and login, it says a critical update failed. I don't know how to remove the message. But happy I can login now.
