well it seems something went wrong so lets investigate a bit…
- You can see Grub Menu?
IF Yes --> then from Grub you can boot to terminal by editing the grub menu and adding number 3 at the end of your boot kernel parameters line
for example -> linux /boot/vmlinuz-linux root=UUID=26dfcc2f-41e4-4c70-a2a9-ae62100ddf61 rw quiet pcie_aspm=off elevator=deadline 3
if you manage to boot to root now you can reinstall everything you want and you can use even --force option .
Edit your lightdm conf file nano /etc/lightdm/lightdm.conf
make sure that everything looks ok
for example check if -> user-session=plasma
Most of the times the blinking cursor is something messed up with graphic drivers or xorg configuration so you either need to generate a new xorg or install the correct drivers but if you say is something with the login screen I will stop here.
Thats it for now , good luck!
further more I have discovered that having all 3 monitors at resolution 1920x1080 Powermizer is working fine.
If I have one monitor at resolution 2560x1440 and the other 2 at resolution 1920x1080 powemizer is NOT Working
I have tried setting up 2x Monitor at 3840x2160 and is working fine but if I connect a third monitor at 1920x1080 Powermizer is not working it has to go full performance.
I have tried also 2x monitors 2560x1440 with 1920x1080 … 2560x1440 with 3840x2160 and powermizer is working
But with 3 monitors different resolution is not working
nvidia-settings -a ‘[gpu:0]/GPUPowerMizerMode=0’
where 0=adaptive 1=maximum performance and 2=automatic
Nothing of these are working on the fly so is another indication that powermizer is broken
inside xorg.conf or better 20-nvidia.conf
in the “Device” section for your graphics cared, add:
adaptive strategy for any power source
Option “RegistryDwords” “PowerMizerEnable=0x1; PerfLevelSrc=0x2233; PowerMizerDefault=0x3”
batt=max power saving, AC=max power saving
Option “RegistryDwords” “PowerMizerEnable=0x1; PerfLevelSrc=0x3333”
batt=adaptive strategy, AC=max performance
Option “RegistryDwords” “PowerMizerEnable=0x1; PerfLevelSrc=0x3322; PowerMizerDefaultAC=0x1”
batt=max power saving, AC=max performance
Option “RegistryDwords” “PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x1”
batt=max power saving, AC=adaptive strategy (my favorite)
Option “RegistryDwords” “PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x3”
Does these settings will make powermizer to AUTOMATIC jump power levels according to what application or game I Am gonna run because as I see it , it will only adapt one strategy
My problem is powermizer that does not AUTO switching level profiles, If you have nvidia you will understand
Powermizer always uses max perfomance and I dont want that because is using my GPU 100% even when my PC is idle…
Even the fans of the GPU are working to the MAX and is very noisy and besides that it consume a lot of power.
@kyrisk I have fixit by generating a new xorg
Option “RegistryDwords” “PowerMizerEnable=0x1; PowerMizerDefaultAC=0x3;”
VendorName "NVIDIA Corporation"
Option “Coolbits” "12"
Option “RegistryDwords” "PowerMizerEnable=0x1; PowerMizerDefaultAC=0x3;"
I have noticed that PowerMizer is not working anymore and it seems that the card is constantly working at performance level , I have tried a lot of things but no success , NVIDIA stacked at maximum performance.
1.I have re installed Nvidia drivers , kernels etc
- Disable compositor in Plasma
- I have removed all widgets
- Install dkms,kernel and drivers
Well I run out of ideas so am just wondering if the same thing is happening to you as well or is just my pc. :o?
