I recently purchased Razer Blade 15 Advanced Model - (OLED 4K Touch 60Hz - GeForce RTX 3080) and installed Ubuntu 21.04, dual boot with Windows. Since the minute I installed I'm having some random flickering and system freezes, meaning everything freezes quite randomly (sometimes after a few hours, sometimes less). I tried a ton of solutions offered online to solve the freezing problem, now it doesn't seem to freeze, but instead whenever I close and open the lid or just suspend it, it either reboots or crashes with a "*ERROR* CPU pipe A FIFO underrun" error or is stuck in a terminal login. My current setting is the following: CUDA 460.91.03 (I tried 470 and 495 but then I had my laptop randomly freezes) I disabled secure boot In grub I added GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" Bios version is 1.10 PRIME profiles in Nvidia x server settings is set to NVIDIA On-Demand If there's any further information needed, just let me know what to run/check and I will. Any help in solving it will be greatly appreciated.
