xubuntu 12.04 black screen on wake

rated 0 times [ 2] [ 0] / answers: 1 / hits: 1161 / 2 Years ago, mon, october 24, 2022, 5:17:10

In /var/log/suspend.log, all is a success or not applicable, except these lines:

Having NetworkManager put all interaces to sleep...Failed.



Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file or directory



Having NetworkManager wake interfaces back up...Failed.

I'm not sure that they are relevant, but I'm stymied.

I tried adjusting the brightness via keyboard, and also tried opening a terminal and commanding a shutdown, but neither worked, so it appears to not load properly at all, though the screen backlight is powered and the system is running.

This is an HP Pavillion Dv7 notebook.

I have a suggestion which might be worth trying,

If your system has AMD/ATI graphic card and you are using Proprietary drivers then try disabling them and using the default/ Xorg Radeon drivers, one that Ubuntu selects.

(This may or may not work.. Its Only a guess..)
