Nvidia card not working properly

[karypid]

I currently go into the BIOS and set the graphics mode to "Intel UMA" in order to have a stable experience.

When enabling the Nvidia drivers, I get:

• Unstable suspend/resume (system sometimes never wakes up)
• Terrible battery life even if not making intense use (seems like GPU is consuming power)
• System log is spammed with nvidia-powerd errors

Regarding the last point, the log contains:

Apr 26 20:50:40 myhost /usr/bin/nvidia-powerd[6008]: error setting power limit
Apr 26 20:50:40 myhost /usr/bin/nvidia-powerd[6008]: Error setting GPU limit: 55000.
Apr 26 20:50:40 myhost /usr/bin/nvidia-powerd[6008]: error setting power limit
Apr 26 20:50:40 myhost /usr/bin/nvidia-powerd[6008]: Error setting GPU limit: 55000.
...

The latest Fedora kernel seems to fix this. I am currently using:

❯ rpm -qa | grep kmod-nvidia
kmod-nvidia-6.8.8-300.fc40.x86_64-550.78-1.fc40.x86_64

~ 
❯ rpm -qa | grep kernel
kernel-modules-core-6.8.8-300.fc40.x86_64
kernel-core-6.8.8-300.fc40.x86_64
kernel-modules-6.8.8-300.fc40.x86_64
kernel-6.8.8-300.fc40.x86_64
kernel-modules-extra-6.8.8-300.fc40.x86_64
kernel-tools-libs-6.8.8-300.fc40.x86_64
kernel-tools-6.8.8-300.fc40.x86_64
kernel-headers-6.8.3-300.fc40.x86_64

With kernel 6.8.8 and drivers 550.78, all issues seem resolved:

• Stable suspend/resume
• Good battery life
• No more nvidia-powerd errors spamming the log

Since I've used this kernel/drivers for less than 24 hours, I will wait a few more days and then close this issue (provided things keep working as they have for the past several hours).

I have been using the card without issue in the past 4 days. I tried several games from Steam, as well as used PyTorch for some tensor operations with acceleration. No issues at all. Suspend/Resume has also been flawless.
