As absolute newbie I recently installed Linux Mint 19.2 Cinnamon on Lenovo SL500 with GeForce 9300M GS. Everything went relatively well up to the point, when the Nouveau driver was replaced by Nvidia driver (340.107 - 0ubuntu0.18.04.3) as was recommended by Driver manager.
Then the system started freezing after few minutes after restart.
It took me a while to discover that the issue is caused by the Nvidia Powermizer function, which change the performance level of the graphic card by stepping down the clock. It seems to work well in lower direction up to the point, when the lowest level is achieved. Than, if the system require to increase the frequency by some load (for example -opening, or closing the windows) the system will start freezing intermediately.
This issue does not happen if the PowerMizer is switched to "Prefer Maximum Performance" mode in NVIDIA X Server Setting. Than the system work nicely.
I have spent few days on this forum to find some workaround. I tried to create xorg.conf with
Code: Select all
Option "Coolbits" "13" Option "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerDefaultAC=0x1"
So, any advice will be more than appreciated. Thank you.
