 |
|
Hi, I have a multiseat installation with 2 seats now. I use mate-desktop.
Everything works just fine, but if mate-power-manager is installed it prevents me for having even the power on self screen.
I cant get any display what ever I try, restarting display-manager does not bring up the display and reboot does not help
either. Display is completety dead until I remove mate-power-manager, after that display starts to work as it should.
I have two different nvidia cards and this happens only on GTX 970, 1070 keeps working, 970 gets totally jammed.
But how can I prevent mate-power-manager to newer install again on my system? Arent there some depedencies that installss it again and again?

If you want a package not to be installed, then emerge --ask --verbose --depclean package to get rid of it. Once it is gone, add it to /etc/portage/package.mask to keep it out.
In the cases where this fails, is the system alive with no video (but reachable over ssh) or is it completely dead? Does ACPI soft-off work or are you required to use the 8-second-hold hard-off? If the system is alive at all, do logs afterward show any messages about why it was broken? |
