System wide stuttering



You have all this installed and the same user for them?


It actually doesn’t happen on the live install. No I didn’t, I install them one by one. If it didn’t work, I just moved to another distro.


This is a good starting point to trace the issue.

I understand, but are all on the same system or on separate partitions? Same user with the same /home is a mix that i always avoid when comes to multiple DE’s.


I installed them on the same system (Same hardware). I had them on the same hard drive, but if I had the issue I would wipe the hard drive and install the next distro. Just to be on the safe side.


I found there’re something odd in your xorg.0.log. First some nvidia options in your config are not used (at least not mentioned in xorg log), and second as quoted above is the mode changed to “nvidia-auto-select”. Here’s my config, you can try to set mode explicitly and move nvidia options to “Device” section. Good luck!

if xorg loads config correctly, in xorg log there will be some hints about options, like below:

I added those into my config and it’s still doing it. I have a pcie error when booting but it says it has been corrected. If that’s any help.


Update your BIOS that might be messing with things


Thanks for the tip. I updated and it’s still messing up. It seems to be doing it less often now.


Next question, why are you using the 4.9 kernel on an 8th gen processor. Add the 4.14 and 4.19 kernel. Test them both. Then check your BIOS settings and make sure you don’t have an overclock, undervolt setting tha tmight be messing with things. If you do drop it to stock settings for freq and voltage.


I also noticed that you have two outputs (displays) connected, and DPI is set to

(--) NVIDIA(0): DPI set to (110, 114); computed from "UseEdidDpi" X config

I’m not sure if you use multiple monitors or single one. Can you try to use one output and set DPI to 96?Then test and check if come back normal.
