[Kernel-packages] [Bug 1911055] Re: [modeset][nvidia] suspend/resume broken in nvidia-460 : Display engine push buffer channel allocation failed

2022-01-16 Thread Tolga Durak 
I'm also having the identical problem with external monitor connected
via only HDMI. No problem with DisplayPort.

Screen does not wake up from sleeping when using refresh rate 240 Hz. It
is fine with 60 Hz.

My graphics card is RTX 2070 Mobile

Using Ubuntu 20.04.3 LTS and Nvidia driver 470.86

[Kernel-packages] [Bug 1951166] [NEW] nvidia_drm error at the end of kernel ring buffer (dmesg)

2021-11-16 Thread Tolga Durak 
Public bug reported:

Recently, I have noticed an error about nvidia_drm logged several times
on my kernel ring buffer output occasionally.

G-SYNC monitor.
