View Full Version : [SOLVED] Screensaver recovery and system fan

October 20th, 2018, 12:05 AM
Good day all,

Additional problems with upgrade to 18.10. When screensaver, or more accurately screen blanking happens, nothing will restore the screen, except a power off reboot. The second issue is the fan is running constantly, and the keyboard is warm when there is nothing actually requested from the CPU and the monitor shows no CPU activity.

I have tried reinstalling (using Synaptic) all installed python, xfce, power, and gdkpixbuf (due to errors seen in the original dist-upgrade terminal output). No luck so far.

This is a System 76 Bonobo laptop running Xubuntu. The issues found prior to upgrade were all resolved, and the system was running very well prior to upgrade.

Please let me know if additional information is needed to find a resolution.

Can you use other options of ubuntu when booting, and test the old kernel wich should still be there?

Interesting. I rebooted and was presented with two options under Ubuntu Advanced. and I chose the older one and when the boot completed let the screen go blank. Using the mouse the screen recovered. Also, the issue with the fan running constantly went away.

I then rebooted into the normal Ubuntu and the screen blanking issue returned, but the fan running has stopped. I suppose I will need to wait for a new kernel for the fix now. Is there some place I should report this, or do the kernel folks read this?

Well, the fan running constantly is back. Nothing taxing to the CPU is happening.

Think to always clean the system after a dist-upgrade, to purge orphans and old settings left behind, and often disturbing the system.
Use 'autoremove' 'gtkorphan' and/or 'bleachbit'

The system has been cleaned with apt-get autoremove, apt-get autoclean, and bleachbit. No help.

Reading in a different thread I tried running

journalctl -b

Here is the output


There were several red highlighted lines, unfortunately they did not remain red when copy and pasted into pastebin.

I have no idea what to do with this information.

My query to System76 got a response. They recomended:

sudo apt purge nvidia* && sudo apt autoremove
sudo apt install system76-driver-nvidia

And that has worked.

Thank you everybody.
