I’m using Ubuntu 20.04 LTS on my Thinkbook14+ with GeForce RTX 2050. Everything worked fine until the system performed an unattended-upgrade that upgraded the kernel from
Start-Date: 2022-07-01 07:23:27 Commandline: /usr/bin/unattended-upgrade Install: linux-headers-5.14.0-1044-oem:amd64 (5.14.0-1044.49, automatic), linux- image-5.14.0-1044-oem:amd64 (5.14.0-1044.49, automatic), linux-modules-5.14.0-10 44-oem:amd64 (5.14.0-1044.49, automatic), linux-oem-5.14-headers-5.14.0-1044:amd 64 (5.14.0-1044.49, automatic) Upgrade: linux-oem-20.04:amd64 (220.127.116.112.38, 18.104.22.1684.40), linux-headers-o em-20.04:amd64 (22.214.171.1242.38, 126.96.36.1994.40), linux-image-oem-20.04:amd64 (5. 14.0.1042.38, 188.8.131.524.40) End-Date: 2022-07-01 07:23:55
After the upgrade, the system gives black screens when I reboot with Nvidia selected as prime (But that doesn’t happen when I switch the prime to Intel or on-demand).
I had been using the Nvidia driver
515.48.07 from Nvidia.com before I encountered the problem. I’ve tried:
- Reinstall the driver
- Upgrade the driver to
nvidia-driver-515from PPA instead
- Roll back the kernel to
But none of them works.
Log file from recovery mode is attached. I would be really grateful if anyone can help.
